Error p0441 viburnum 8 valves

Modern technologies are developing, equipment is becoming more complex and sophisticated, and progress does not bypass vehicles. Carburetor cars were very simple, and any driver could figure them out, but on cars with injection engines, new components were added, in particular, a fuel vapor recovery system appeared, the main element of which is the adsorber. The main task of this circuit is to remove fuel vapor from the tank into the intake manifold at the time the internal combustion engine is started, and the adsorber purge valve plays an important role here. This article will discuss the operating principle of this system, the procedure for replacing the valve, and possible malfunctions that may arise during the operation of a Lada Kalina passenger car.

How to fix error P0441 on Lada Kalina

In today's article we will talk in detail about what causes error P0441 in the Lada Kalina car and how to fix it. To begin with, it must be said that this brand of car is equipped with an injection engine, which, unlike a carburetor, has additional components, as well as a fuel vapor recovery system, where the main component is an adsorber. Its task is to remove fuel vapor from the tank into the intake manifold at the moment when the internal combustion engine starts, and an important role here is played by the adsorber purge valve. Error P0441 just indicates incorrect air flow through this valve.

Description and meaning of error P0422

This diagnostic trouble code (DTC) is a generic powertrain code, which means it applies to OBD-II equipped vehicles. While general, specific repair steps may vary depending on the make/model. A vehicle's catalytic converter (catalyst) helps improve tailpipe emissions by oxygenating the exhaust gases. It helps convert carbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx) into water vapor (H20), carbon dioxide (CO2), and nitrogen (N). The PCM (Powertrain Control Module) monitors catalyst efficiency through the catalyst post oxygen sensor. This sensor is mainly used for this purpose. It should shift much slower than the front oxygen sensors. If at any time the PCM detects that the catalytic converter O2 sensor is switching too quickly (without indicating any change between the input and output of the catalytic converter), then it interprets this as the catalyst not functioning properly. Bank 1 is the side of the engine with cylinder number 1.

The principle of operation of gasoline vapors in Lada Kalina

The car was equipped with this system to prevent harmful vapors emitted by gasoline from entering the atmosphere. It consists of:

fuel shut-off valve;
adsorber;
connecting pipelines;
solenoid valve for purging the absorbent component.

The main thing here is the adsorber, as was already mentioned at the beginning of the article, and it consists of activated non-edible carbon in a plastic case. The vapors that form from gasoline are absorbed by the absorbent component and accumulate in it over time.

When the engine starts, the canister purge valve comes into action, releasing all existing vapors that enter the intake manifold, after which they burn out.

Violations in the system

There are few problems observed here, since the design of the device is not at all complicated. The solenoid valve may not open or, conversely, not close, or may be stuck in any other position. But the system can malfunction for other reasons, for example:

there are malfunctions in the operation of the control unit;
there may be a break in the circuit and, as a result, there is no voltage in the valve;
connecting pipes may be clogged or pinched;
The carbon filter is clogged.

A situation where the control panel does not close can lead to the following problems:

the dynamics of the internal combustion engine will decrease;
fuel consumption will increase;
the mixture will be excessively rich, and, as a result, a black coating will appear on the spark plugs;
the engine will begin to malfunction, which will be especially noticeable at idle.

When the valve, on the contrary, is constantly closed, vapors accumulate in the gas tank that exceed the permissible limits, and therefore the fuel pump or fuel level sensor may fail.
All malfunctions in the system are recorded by the control unit, and a check engine light is displayed on the dashboard. The error code is determined by a special diagnostic device or a computer with the necessary program installed. The most common errors in this regard are codes P0441 and P0455.

Auxiliary valves grant 8 valve (2000)

100-103 – the throttle valve drive is broken or there is damage to the wiring;
105 – monitoring system is faulty;
122-123/127-128 – pedal position sensor A/B low or high value;
187-188 – incorrect adjustment of the fuel mixture at idle, lean or excessively rich;
135/138 – resynchronization of throttle/gas pedal position sensors;
176/178 – incorrect adaptation of the remote control drive;
270-271 – oxygen sensor No. 2 in the exhaust system does not respond to enrichment or leanness of the mixture;
301/304/307/310 – the ignition coil is closed to 12V, respectively, for all combustion chambers in series;
500/501 – generator excitation starts incorrectly.

Error P0441 in the Lada Kalina car

The reasons for this problem may be:

Problems in the operation of the adsorber valve.
Clogged air line running from the canister purge valve to the air filter.
Perhaps the pipes are leaking air.

In most cases, the malfunction lies precisely in the purge valve, which is a common problem with the Lada Kalina. If necessary, it is recommended to simply replace it with a new one.

When a valve begins to malfunction, this does not indicate that the engine is losing power or, for example, that the fuel pump will no longer function correctly. In most cases, this just leads to a higher level of exhaust emissions, as well as an intermittently displayed Check Engine light.

Perhaps this is precisely why many Lada Kalina owners are in no hurry to repair their car if error 0441 is present. After all, you can ignore the lamp (for the time being), gasoline is consumed as before, and there are no special malfunctions in the fuel system. But at the same time, it is recommended not to leave any problems in the car for later, to diagnose, repair and replace the necessary parts on time so that the car serves for a long time and without failures.

Valve repair

Deciphering error codes for Lada Kalina (1st and 2nd generation)

Checking and purging the valve

The first signs that the Kalina adsorber needs to be repaired are the appearance of a persistent smell of gasoline in the car interior and difficulties that arise during draining the fuel. For repairs, it is necessary to remove the adsorber and disassemble it. Since the device is usually solid, for disassembly you will need to cut off the cover. This can be easily done with a regular file. After repair work has been carried out and replacement of the main parts, the cover is usually simply sealed. For complete sealing, the seams are treated with resin. The resin dries within 12 hours. After this, it can be lightly sanded to bring the filter into proper shape.

Spent and unusable coal is poured out of the adsorber. Foam rubber is suitable as intermediate filters. Remove the old filters and replace them with new ones, prepared in advance. Some craftsmen believe that foam rubber is not particularly effective and will allow all the dirt and coal to pass through, so filters can be made from felt. You can place a piece of cotton fabric between the device and the felt, which will prevent small threads from getting into the system. The resulting gaskets are glued to the base and treated with sealant.

When the dry coal is filled in, felt filters are installed again. All the plates and springs are put in place, and then the filter itself. As can be seen from the above, it is not difficult to diagnose and repair the Kalina absorber valve; you can do it yourself. Good luck!

The influence of the fuel vapor recovery system on the operation of the Lada Kalina engine

How does a mechanic diagnose a p0441 code?

First, the mechanic will connect the OBD-II scanner to the vehicle's diagnostic port and read all the stored data and error codes.
He will then clear the error code from the ECM and test drive the vehicle.
If P0441 appears again, have a mechanic visually inspect the evaporative emission system.
The mechanic will then check the fuel pressure sensor in the fuel tank for damage.
He will also check the fuel cap.
He will then check the operation of the vacuum switch and purge valve.
If no problem is found, the mechanic will perform a thorough check of the evaporative emission system to check for leaks.

How does the Lada Kalina gasoline vapor recovery system work?

The EVAP system in question was created to prevent the release of harmful gasoline vapors into the surrounding atmosphere resulting from fuel evaporation; it includes:

fuel shut-off valve;
adsorber;
solenoid valve for purging the absorbent element;
connecting pipelines.

The most important component in the system is the adsorber (also called a carbon filter), the basis of which is activated non-edible carbon, enclosed in a plastic housing. The resulting gasoline vapors are absorbed by the carbon of the absorbent element, gradually accumulating in it. When the engine starts, the canister purge valve (KPA) is turned on, and due to the vacuum, all accumulated vapors enter the intake manifold and then burn out.

On the Lada Kalina, the adsorber is located in the gas tank area, and getting to it is very difficult. To dismantle this EVAP element, it is necessary to remove the fuel tank, but the control unit is located in an accessible place - the valve is located in the engine compartment, in close proximity to the battery, on the rear wall of the air filter housing. It should be noted that for turbocharged engines, a vacuum is not created in the intake manifold, and in order to force the vapors in the desired direction, an additional two-way valve is included in the circuit.

Lada Granta computer errors that are not directly related to the ESD (0400)

422 - a common Lada Granta engine error indicates that the catalyst is clogged or its efficiency has critically decreased, may be accompanied by a drop in engine power, can be eliminated by replacing the module;
441 – the adsorber purge valve does not work correctly or is jammed;
443-445 – damage to the control lines of the above element;
458/459 – short circuit of the canister purge valve lines to ground or 12 volts;
480/481 – respectively for the first and second central fan control relays, open circuit or short circuit;
485 – the head fan is faulty or the module control has failed.

Today we will talk about error P0830 (clutch pedal switch, circuit faulty) in the Lada Granta. The mistake is that when we are driving in second gear, we begin to depress the clutch and shift to third gear, at this moment the engine speed increases. No matter what gear, downshift or upshift, the revs increase. Let's try to figure out the problem.

Raise the steering wheel to the maximum position and also move the seat back. Near the clutch pedal we see the following picture:

The clutch sensor is marked in red, next to it is a green harness that needs to be disconnected in order to remove the sensor itself and check its functionality. The sensor is also secured with two screws on the side that need to be unscrewed; for these purposes, use a small screwdriver; it will be difficult to get another one in there. We remove the clutch sensor and test it using a multimeter. In our case, “ringing” is carried out but the readings “jump”; in the video you can see the diagnostics of the new sensor, there these readings are stable. After installing a new clutch sensor, the error disappeared, the problem with increased speed when switching gears disappeared.

Hello dear subscribers! Today you will clearly see how to overcome error P0830 Clutch pedal switch, the circuit is faulty! In total, I tried to photograph everything in the smallest detail. So there seems to be nothing more to add! So watch, comment and just stock up on experience! Enjoy watching.

Thank you for your attention! Always yours Kazakov Dmitry.

When changing gears, the check light began to light up. Bortovik - BK-STAT showed P0830 - malfunction of the clutch switch. The clutch status is transmitted to the vehicle's ECU via the clutch switch. Pressing the clutch pedal while driving takes the load off the engine. However, the ECU assumes that there is a load because it receives signals from the VSS sensor and therefore controls the unloaded engine as if it were loaded. Since in this case the optimal control of fuel injection is disrupted, the engine speed becomes uneven and smoke is generated. The clutch status signal is transmitted from the clutch switch. This signal allows the ECM to process sudden changes in load on the vehicle's engine. In addition, the clutch switch signal, along with vehicle speed and engine speed signals, is used to determine which gear is engaged.

Design of the VAZ Kalina adsorber purge valve

KPA is present on all modern injection internal combustion engines, and Lada Kalina is also no exception. The purge valve (another name is Evap-Solenoid) is connected on one side to the carbon filter, on the other to the intake manifold, when there is no electrical signal to the control unit, the pipeline channel is closed, and vacuum is not created in the system. When an electrical signal is supplied while the engine is running, the valve is activated, the channel opens, and gasoline vapors freely pass from the adsorber into the intake manifold.

Malfunctions in the fuel vapor recovery system Lada Kalina

Since the solenoid valve itself is not a complex device, it has few malfunctions as such - it may not open or close when necessary, or may freeze in a certain position. But the culprit of the breakdown may not only be Evap-Solenoid; the gasoline vapor recovery system does not work correctly for other reasons:

connecting pipes are pinched or clogged;
normal vacuum is not created in the system;
due to an open circuit, there is no voltage on the valve;
the carbon filter is completely clogged (which is rare);
The control unit malfunctions.

If the CPA is stuck in the open position and does not block the channel, the following defects may occur:

the fuel mixture becomes richer, causing “blackness” to appear on the electrodes of the spark plugs;
the engine begins to operate unstably, this is especially noticeable at idle;
gasoline consumption increases;
The throttle response of the internal combustion engine decreases.

When the EVAP channel is constantly blocked by the purge valve, excess vapor pressure is created in the gas tank, due to this:

there is a risk of fuel pump failure;
The fuel level sensor may fail.

It should be noted that purge occurs in a certain mode after starting the engine, the program is executed depending on the crankshaft speed, and the system does not work at idle. An impulse arrives at the CPA if:

the coolant has heated to a temperature of at least 75 degrees Celsius;
the throttle valve is open at least 4%;
the car is moving at a speed of more than 10 km/h (but this is not a necessary condition).

Problems in the electrical part of the EVAP are detected by the control unit, and the Check Engine warning lamp lights up on the instrument panel. The fault code can be determined using a special diagnostic scanner or a computer with a program installed; the most common errors in the vapor recovery system detected by the diagnostic device are P0441 and P0455.

Common Problems Causing Code P0441

In many vehicles, including VW, Audi, Nissan and Mazda, a bad purge valve is the most common culprit for code P0441. The purge valve (also called the purge solenoid) is easy to replace in most vehicles.
Often when the canister begins to fail, carbon granules are drawn into the purge line and clog the purge valve or purge lines. If there are a lot of carbon granules stuck inside the purge valve, the canister may also need to be replaced.
In many Toyota and Lexus cars from the 90s - 00s, there is an EVAP VSV valve and vacuum hoses on the canister that need to be checked. Often the VSV fails, or one of the vacuum hoses becomes clogged with carbon granules from the adsorber.
Unfortunately, Toyota sells the EVAP VSV valves as one piece with the canister, but they can be purchased separately from a third party. In any case, all vacuum hoses connected to the EVAP VSV valves must be replaced, and metal vacuum lines must be checked for blockages and cleaned.
The 2003 Toyota Technical Bulletin (TSB) also mentions an inoperative Canister Vacuum Switching Valve (CCV VSV) as a possible cause for codes P0441 and P0446. The CCV VSV should be checked and replaced with an updated part if it does not work.
In 2002-2007 Dodge and Chrysler vehicles, it is quite common for the NVLD device to fail and cause code P0441.

Replacing the adsorber purge valve on Kalina

If the check shows that the Evap-Solenoid is faulty, the part must be replaced (catalog number - 11181164200). There is no point in repairing the device:

the price of the valve is in the range of 400-800 rubles;
You can buy the device in almost any store that sells VAZ spare parts;
changing the KPA is very easy and simple.

But before making a replacement, it would be a good idea to check the control circuit; quite often the valve does not work due to a break in the wires going to it. To complete the work, you will not need a pit or a lift, and the procedure itself will take no more than one to two hours, even if the operation is performed by an inexperienced worker without metalworking skills.

We change the valve as follows:

turn off the ignition, raise the hood;
find Evap-Soleno >
just in case, disconnect the negative terminal from the battery;
move the plug tab to the side and disconnect the wires;
so that the air flow sensor does not interfere, use a Phillips screwdriver to loosen the clamp securing the air duct, and move the pipe to the side. For convenience, the air flow sensor can be removed;
Now access to the valve is free, all that remains is to gently pull it up to pull it out of the grooves;
but that’s not all - since the tube on the valve itself is sealed, we do not touch this connection for now, it is necessary to release the other end of the hose, to do this we remove the latch and pull the pipe out of the connection;
We dismantle the valve together with the tube, and the disassembly is almost complete.

Replacing the purge valve could be considered a very simple task, if not for one “but” - it is very difficult to remove the plastic tube from the CPA without damaging it, and it does not come with the new valve. There are two options here:

try to carefully heat the connection with a hairdryer and pull off the pipe;
cut the tube at the connections, and instead buy an ordinary fuel hose with a diameter of 8 mm and two clamps.

Having measured the required length of the hose, cut it, connect it to the valve and connector, we get approximately the same design as in the figure below.

We install everything in place, start the engine, and test the car on the move.

The adsorber valve is knocking on Kalina

Many owners of Lada Kalina cars are faced with a problem - while the engine is running, an incomprehensible clattering sound is heard from under the hood; when identifying the cause of the noise, it turns out that the sound comes from the purge valve. Although the knocking does not affect the operation of the car in any way, some car owners are annoyed by it, and car owners want to get rid of it. You can “overcome” the unpleasant clattering sound; you just need to do the following:

remove the valve and inspect it carefully;
Find the adjusting screw on the side; it will be filled with epoxy resin on top;
pick out the epoxy, tighten the screw half or three-quarters of a turn;
install the valve in place, check for changes in the operation of the internal combustion engine.

You cannot tighten the screw any more, in this case the control panel will stop opening, and the engine diagnostic lamp on the instrument panel will record an error. It is also worth noting that some drivers confuse the clatter of the solenoid valve with detonation, but in principle, the sounds can be distinguished. You just need to take into account that detonation occurs under load, for example, when a loaded car is moving uphill, in this case they say “fingers are ringing.”

What does error p0363 mean?

To detect misfires, the PCM uses data from the crankshaft and camshaft position sensors and also takes into account the number of engine revolutions per minute. If the PCM detects that the camshaft or crankshaft position has changed and is abnormal under current conditions, or that the actual engine speed is not at the required value, it will assume that one of the engine cylinders is misfiring. In this case, the PCM will cut off fuel to that cylinder and store P0363.

What is the essence of this system

Kalina's automatic fault diagnosis system includes several devices. The display displays information that is processed by all devices. To prevent car owners from having to independently service their cars, manufacturers do not try to talk about the location of the devices and their decoding. This is explained quite simply: if a car owner who does not have the proper experience decides to repair the Lada Kalina on his own and without the advice of specialists, seeing error 0441 on the display, then he can only worsen the technical condition of his “four-wheeled friend.”

It should also be borne in mind that the information received from the automatic diagnostic system is processed by the on-board computer, which simplifies the repair of the automotive unit, since the owners have the opportunity to visually find out where the defect is found.

Since the Lada Kalina does not have an on-board computer, the owner will only be able to visually familiarize himself with the code number, and he will have to guess the location of the breakdown on his own. In order to avoid mistakes when repairing your car, experts recommend knowing each code by heart in order to promptly eliminate any type of malfunction.

Diagnosis of faults using the dashboard

Owners of the Lada Kalina need not only to know the fault codes by heart, but also to understand how to diagnose the health of the car using the dashboard, on which the analyzed codes are displayed.

To run diagnostics you need to do the following:

activate a button that calculates the car’s mileage per day;
continuing to hold it, turn the ignition key;
if everything is done correctly, the arrow of the electronic elements will begin to move from the current position to the designated one;
after the arrow reaches its final position, you will need to activate the button located on the wiper switch so that the received information is switched to the screen;
When this button is activated, the functionality of electrical appliances will be displayed on the panel, which will allow car owners to quickly identify the malfunction and quickly fix it.

According to this scheme, you need to update the information on the instrument board three times so that you can visually familiarize yourself with the error codes, which are indicated by numbers:

2 indicates a problem with the mains voltage;
3 warns of a breakdown of the sensor that monitors the fuel level;
4 shows that the cooling system sensor has failed;
5 warns that the temperature sensor has failed;
6 warns of engine overheating;
7 indicates that the oil pressure has dropped significantly;
8 warns of problems in the brake system;
9 indicates that the battery is low.

Video response about error 0830

A video made by our friend Grantovod will help you solve the problem.

We had the same garbage, check the wires under the pedals. If everything is fine there, then it’s better to go for diagnostics

Another option is to change the clutch pedal sensor. Everything is done very quickly and for pennies. It should help.

Immediately after this, I took the car for diagnostics. It's safer than fixing it yourself.

It's something to do with the clutch. Well, more precisely, everything is fine with him, but the wires either came off or were broken. If you have a clue about cars, fix it yourself; if you don’t, take it to a service station.

Thank you - it’s a breeze to repair..... I’m worried about why BC told me this - why didn’t the check light come on?

Dmitry the check light will light up in 10-15 minutes, checked for other errors.

We need to talk less and get closer to the point.

Disassemble the old sensor and clean the contact area in it, and a multimeter will show the same resistance as on the new one. It’s just that over time a film, soot, oxide, etc. appears on the contacts.

I also got this error, but everything is fine with the car, except for the constantly beeping handbrake warning light. It would be nice if the light just came on, but this squeak is killing (I turned the music up louder, it also gets boring). The fault was with the button under the handbrake lever, but replacing it didn’t help. The car is 5 years old, 106,000 miles, the clutch sensor was changed at about 90,000. Otherwise, there are no problems, the car is unpretentious, but even an old woman can get into trouble. If anyone has encountered such a problem. Write how you found the solution. Thank you.

Hello! Lada Granta automatic transmission is blocked. Please advise what to do. I drove it to a hundred, but to no avail. What could be the reason? The battery was not in the car for 3 days. Please advise what to do? Thank you

This is not a sensor. An ordinary microswitch costs 300 rubles per bucket, not per piece. Go to a radio store, buy and re-solder two wires.

Error codes that are logged as errors by the engine control module memory belong to a specific type of diagnostic information. The interpretation of codes is useful for any owner, including the owner of a Lada Kalina.

Through these encrypted information units, the process of self-diagnosis of all on-board electronic components in the car is carried out. This is very useful because it provides the ability to identify a malfunction before a critical failure of a system component occurs.

Diagnosing faults using car controllers: what to do

You can diagnose faults for the Lada Kalina not only using the dashboard, but also with the help of separate automobile controllers, which are responsible for the operation of a specific component or unit of the car.

You can find out how the code is decrypted in a reference book or using a special software program. After all, remembering all the codes by heart is not so easy, especially for novice car enthusiasts.

Let's look at a few of the most common codes that the diagnostic system can show:

Lada Kalina error 0441 will indicate a breakdown of the oxygen access sensor.
Code 1602 will indicate that the computer is not receiving voltage from the network.
Code 0363 indicates a breakdown of the car coil.
The controller marked Bosch-ME-7.9.7 will report an engine malfunction.

It is worth noting that the diagnostic system does not always accurately indicate the element that has failed; most often, this system indicates the area in which the problem occurred. That is, such a system prompts the car owner about a malfunction in a certain component, so that the car owner corrects the breakdown in a timely manner, having first made a more accurate diagnosis of the defect. For example, if error code 0504 is displayed, this will indicate a malfunction in the system responsible for the brakes, and what kind of malfunctions have occurred can only be determined after a thorough study of the performance of this system.

Troubleshooting methods

Now that all the causes have been identified, we can begin to consider troubleshooting. But, before we begin, it is worth noting that a car enthusiast needs to have an idea of the design features of the engine if he wants to fix the problem himself. Otherwise, go directly to a car service center, in order to avoid other problems that, due to lack of experience, car enthusiasts usually create for themselves.

Sensors

Often, the reason why the check light on Kalina may come on is the failure of one of the sensors. Possible ones that are worth checking right away include: mass air flow sensor, idle speed control, crankshaft position sensor, oxygen sensor and coolant temperature sensor.

But, there is a simpler and more effective way to determine the malfunction of a particular sensor, namely connecting to the electronic engine control unit. Here you can look at the errors and, by deciphering them, determine where the problem is.

Throttle

A clogged throttle valve can often cause the check engine light to come on because not enough air is supplied to the power unit. The solution to the problem is cleaning. This process can be carried out using carburetor cleaning fluid or VD-40 fluid.

The part is removed from the car and cleaned, after which it is installed in place. It is also recommended to check the throttle position sensor, which may have failed.

Injectors

One of the common reasons for the “check” icon to appear on the dashboard is a malfunction of one or more injectors that do not spray the fuel mixture properly. So, it is worth dismantling all the elements and checking them using a special stand.

If there is none, then you can use the traditional method by pouring flushing fluid into the fuel supply pipes and activating the injectors using the battery. This way it will be clear which injector is not working well. But, experienced auto mechanics recommend cleaning and checking the nozzles on a stand, since the effectiveness of the procedure is higher.

Fuel pump and filter

Another cause of the malfunction may be a malfunction of the gasoline pump or its filter. Lack of power or contamination of the filter elements leads to the fact that an insufficient amount of fuel will enter the power unit to form an air-fuel mixture.

The malfunction can be cured by checking the functionality of the gasoline pump, as well as by replacing the filter inside the gasoline pump. It is also worth looking at the fuel filter, which could become clogged when pouring low-quality gasoline.

Air filter

A clogged air filter can cause insufficient air in the combustion chambers. So, to check this element, it must be dismantled, which is done quite simply. By inspecting the filter element, you can find out how dirty it is and whether the product needs to be replaced. So, after replacement, the check signal from the dashboard may disappear.

Spark plugs and high voltage wires

Wiring is also often the reason why the check icon lights up on the panel. This happens when the spark plug is inoperative or there is a breakdown in one of the high-voltage wires.

Diagnostics and decoding of codes on Lada Kalina

The Lada Kalina car is equipped with an on-board computer, which allows you to quickly diagnose any faults that have arisen. Thanks to the control unit, you can find out about car breakdowns thanks to readable codes. In this article we will tell you what the most common Kalina error codes are and how to diagnose it yourself.

How to Troubleshoot or Reset Trouble Code P0441

Some suggested steps to troubleshoot and fix error code P0441:

A common fix is to replace the leak detection pump/LDP.
Repair damaged EVAP lines or canister.
Repair the open or shorted voltage supply to the purge solenoid.
Correction of the circuit going to the ECU.

Diagnostics

If you notice that something is wrong with the operation of the Lada Kalina vehicle, then it makes sense to diagnose the car. As a rule, all breakdowns appear immediately after checking the car. You can ask for help in carrying out diagnostics at a service station, where you will pay a certain amount for this service, or you can do everything yourself. Of course, with the help of special equipment there is a greater chance of identifying a malfunction, since when checking independently there is a possibility of obtaining inaccurate data.

Decoding combinations

Below we will look at the decoding of error codes. We will not consider all codes: only the most common combinations that indicate a breakdown are given.

Self-diagnosis

So, what codes can be seen when self-diagnosing Lada Kalina.

Code	Error interpretation
2	Code 2 means excess voltage in the vehicle's on-board network.
3	This code indicates a malfunction of the gasoline level sensor in the fuel tank. Possible circuit break.
4	When this code appears, the car owner needs to pay attention to the operation of the antifreeze temperature sensor. There is also a possibility of a circuit break.
5	There is a problem with the outside temperature sensor.
6	The control unit (CU) detected engine overheating. It is recommended to deal with this problem before further operation of the car.
7	Emergency lubricant pressure in the internal combustion engine is reported.
8	If you see this code on the dashboard, then you need to check the functionality of the brake system. The on-board computer recorded an error or breakdown in its operation.
9	The on-board computer reports that the battery charge is too low. It is recommended to perform a more thorough check of the battery.
E	An error has been reported in the data packet stored in the EEPROM.

Diagnostics using equipment

If you check your car for errors using special equipment, then, as stated above, the combinations will be four-digit, and the code will be preceded by a letter.

First, let's look at what the letters and numbers mean.

B - indicates a malfunction of the body, that is, we are talking about airbags, central locking, electric windows. Of course, this is true for Lada Kalina cars equipped with these devices;
C - means an error in the operation of the chassis;
P - indicates a malfunction in the functioning of the engine or automatic transmission.

What does the second number mean:

0 – common code for OBD-II;
1 – number of the car manufacturer;
2 – number of the car manufacturer;
3 – reserve code.

The third symbol directly indicates the type of malfunction:

1 – malfunction of the fuel system or air supply;
2 – malfunctions in the fuel system or air supply are also reported;
3 – malfunctions in the ignition system were detected;
4 – auxiliary control;
5 – malfunctions in idle speed;
6 – malfunction of the ECU or its circuit;
7 and 8 – errors in the operation of the transmission system.

Code	Decoding
P0036	Errors in the operation of the oxygen sensor are reported. It is recommended to check the device for operability, and also check the circuit for opens and short circuits.
P0102	This error code tells the driver about a malfunction in the mass air flow sensor. It's also worth checking the chain.
P0441	Incorrect air flow through the canister purge valve was detected. You should check the valve itself, as well as the entire gasoline vapor recovery system.
P0444	The control unit registered a break in the wiring of the canister purge valve. The circuit should be checked.
P0445	The on-board computer reports a short circuit in the control wiring to ground or the on-board circuit.
P0480	A broken fan relay wiring has been detected. This code can also directly indicate a relay failure.
P0504	A problem has been reported with the brake pedal sensor.
P0830	Malfunctions have been reported in the operation of the clutch switch. It is necessary to diagnose the clutch and identify the breakdown.
P2187	Literally means: the fuel supply system is too lean at idle. Here, first you need to adjust the idle speed. If this does not help, then look for the problem in the fuel supply system itself.
P1115	Incorrect data was recorded in the operation of the oxygen level control sensor. The circuit should be checked.
P1123	In idle mode, the on-board computer registered a too high combustible mixture index.
P1124	At idle, the on-board computer reported that the fuel mixture was too low.
P1127, P1128	The control unit reports too high or too low a fuel mixture indicator in partial engine load mode.
P1135	The Lada Kalina control unit has detected a short circuit or an open circuit in the heater circuit of the oxygen level control sensor.
P1136, P1137	The fuel mixture level is too high or low in low load mode. The internal combustion engine should be checked.
P1141	The on-board computer detected malfunctions in the functioning of the heating device of the oxygen level control sensor.

If you have discovered and eliminated a breakdown, you can reset the error code so that it does not appear again during the next diagnosis. To do this, hold down the daily mileage button and hold it in this position for more than three seconds.

EVAP system components

The main components of the fuel vapor recovery system are:

Fuel tank

Has some expansion room at the top to allow fuel to expand on a hot day without overfilling or leaking the EVAP system.

Fuel cap

Typically contains some type of relief valve for ventilation on older vehicles (pre-OBD II), but is completely enclosed (no vents) on newer vehicles (1996 and newer).

Gas tank separator

Located on top of the fuel tank or part of the expansion tank. This device prevents liquid gasoline from entering the adsorber.

Gas tank separator

Liquid gasoline should not be sent directly to the canister because this would quickly overload its ability to store fuel vapor. The separator is relatively problem-free. The only problems that can occur is that the fluid return becomes clogged with debris such as rust from the fuel tank.

Some separators use a slightly different approach to prevent liquid fuel from entering the canister vent line. A float is installed inside the separator. If liquid enters the device, the float rises and the valve closes the tank vent.

If there is a blockage in the separator or in the vent line between it and the adsorber, the fuel tank will not be able to “breathe” normally. Symptoms include fuel starvation or a warped fuel tank.

If you hear a significant "poof" sound when you open the gas cap, suspect poor ventilation. You can check the tank venting by opening the cap and then disconnecting the fuel tank vent line from the canister. If the system is clear of any blockages, you should be able to blow through the vent line into the fuel tank.

Blowing out with compressed air can sometimes clear the blockage. If not, you will have to inspect the vent line and possibly remove the fuel tank to diagnose the problem.

Ventilation valve

The ventilation valve controls the flow of outside air into and out of the adsorber. In some vehicles it is called the Canister Closing Valve (CCV).

One side of the ventilation valve is connected to the adsorber. The other side is connected to a ventilation hose that has a filter or mesh at the end and is attached to the body or frame of the car.

On some vehicles, the vent valve is attached to the canister. In others, it is installed separately.

Ventilation valve

The ventilation valve is controlled by the engine control unit. Normally the valve is open. It closes when the controller checks the EVAP system for leaks.

Adsorber (canister with coal)

This is a small round or rectangular plastic or steel container. It is usually hidden and may be located in a corner of the engine compartment or near the gas tank.

Adsorber FORD Focus

The adsorber is filled with approximately 0.5 - 1 kg of activated carbon. Coal acts like a sponge, absorbing and storing fuel vapors. The vapors are stored in the canister until the car starts, warms up and drives.

The ECU then opens the canister purge valve, which allows intake vacuum to pump fuel vapor into the engine. The coal container is connected to the fuel tank by a ventilation line.

Under normal conditions, the adsorber causes few problems. Since carbon does not wear out, it should last the entire life of the vehicle.

The most common problem with a charcoal canister is a faulty purge or vent valve. Vacuum purge valves can be tested by applying vacuum directly to the valve using a hand vacuum pump.

Adsorber VAZ

The valve should open and not allow vacuum to pass through if it is good. With solenoid type purge valves, voltage can be applied directly to the coil to see if the valve opens. The solenoid resistance can also be checked with a multimeter to see if there is an open or short.

The purge control strategy in many late model EVAP systems can be quite complex, so the best advice here is to look up EVAP diagnostic procedures in the manufacturer's service literature.
