Error codes for Lada Priora 16 valves with interpretation

On the Priora, like on many other cars, there is a display on the panel behind the steering wheel that displays the status of internal systems. When an error occurs, its number immediately appears on the screen. And there are a lot of these numbers, to decipher them you will need to read the instructions or article.

You often see error 4 there, which means problems with the coolant temperature sensor. What exactly is faulty there is up to the owner to figure out. For this purpose, additional testing and visual diagnostics are carried out.

Why does it occur: reasons

The reason for the appearance of the number on the display is rarely clear without a detailed analysis of the issue; there is only general information. But, according to the experts, the options are as follows:

1. The greatest probability is due to a malfunction of the coolant temperature sensor.
2. Further in descending order - the circuit with this sensor could break.
3. Due to external influences (accident, shock, etc.), the control unit system sometimes malfunctions and generates an error.
4. Plaque on the device may contribute to loss of contact.

Such reasons will not be a serious stumbling block to free travel, and will not make your wallet noticeably empty. Each of the points is completely solvable, both independently and at a service station, you just need to allocate time and a little effort for this.

What to do if your car has trouble starting?

Hello, Alexey. If you have doubts about the flywheel, it is better to contact another specialist for a more thorough diagnosis. But we have every reason to believe that the cause of your problem lies precisely in the battery, especially considering that with a more powerful battery, your Nexia started without problems. Try to check the performance of the battery yourself - we have already described this process, you can handle it, even if you have never encountered such a task.

More detailed instructions are described here. It is also quite possible that the reason lies in the starter; this is a fairly common problem on the Daewoo Nexia. We also wrote about starter malfunctions; we recommend that you familiarize yourself with this material.

How to check on the on-board computer

To carry out a check on the on-board computer, you need to insert the ignition key and simultaneously hold down the button that resets the daily mileage. When the correct actions are performed, all elements on the LCD will light up. And the arrows (speedometer, tachometer, etc.) will begin to quickly and continuously move from zero to the maximum indicator and back. Already here you can see how good the LCD indicator and sensors are.

Next, you can use one of the buttons that switches the functions of the bookmaker. As a result, a set of numbers will appear on the display indicating the version of the program currently installed. Now you need to apply pressure on the key again, then the error codes that are available in this car will appear there.

If you need to reset information from the LCD, it is best to press the button for three seconds, which resets information about mileage during the day. Now it's time to return the light to the sensors and use one of the BC keys. Due to the lack of impact on the system, after about half a minute the instrument panel will return to working condition.

Troubleshooting

There are several methods for troubleshooting the problem, but together they constitute a complete diagnosis of the car for faults in the coolant temperature sensor. After all, error number 4 gives a signal about exactly this. You can fix it like this:

1. First we check the sensor to see how well it functions. It copes with the assigned tasks, there are no complaints about the speed and clarity of data transmission - let's move on to the next point. Does not respond to signals - most likely, it is completely broken and requires replacement.
2. This is followed by checking for contact and absence of plaque. If a problematic connection is identified, the sensor will have to be replaced with a new one. And if the surface is covered with plaque, it is necessary to thoroughly clean the seat.
3. Now you can move on to the on-board circuit, make sure that there is contact there.
4. The remaining dilemmas usually lie in electronics, for this reason the car is taken to a specialist who can adjust the device. Usually in such a situation the ECU is re-flashed, which means that errors are prudently reset.

The issue of eliminating error 4 can be solved on your own, but not in one hundred percent of cases. Sometimes you have to turn to specialists to perform work that requires specific knowledge and skills. But it would be right to try to prevent a breakdown, since most often it occurs after a long period of parking in the cold in an open area (that is, not in a garage or covered parking).

p1558

This error usually occurs on cars with a 127 engine. It is associated with the throttle valve, the quality of which in this power plant leaves much to be desired. P1558 does not interfere with normal engine operation, but you can still try to fix it. Some people solve the problem by flashing it, but we offer a simpler method.

Remove the throttle valve, and then remove the cover - this can be done using a hexagon. We find a plastic gear inside - this is the working part. Lubricate the gear thoroughly and reassemble in reverse order. Most likely, error p1558 will disappear after these manipulations.

What does error 4 mean on Lada Priora and how to fix it

So, when self-diagnosis is carried out and error 4 lights up on the panel, then most likely the car has a problem with the coolant temperature sensor. Many people immediately ask the question “Which sensor should I change?”, but first you need to find out what exactly the problem is.

Note that in order to start self-diagnosis, you need to press and hold the daily mileage reset button + turn on the ignition. After a few seconds, the on-board computer displays an error code.

It is noteworthy that codes in different firmware versions may indicate different problems. Therefore, we recommend that you stock up on an up-to-date reference book. In our case, the software version is 1.0.

How other error codes are deciphered:

• code 2 indicates that there is high voltage in the on-board network;
• code 3 indicates a fuel level sensor error;
• error number 5 indicates incorrect operation of the outside temperature sensor;
• code 6 is engine overheating;
• code 8 – problems with the brake system;
• error number 9 indicates that the battery is discharged;
• P0441 – high or low air flow through the valve;
• P0443 – faulty canister purge valve control circuit;
• P0480 – failure of the cooling fan relay No. 1;
• P0481 – failure of the cooling fan relay No. 2;
• P0500 – incorrect signal from the vehicle speed sensor;
• P0503 – intermittent car speed sensor signal;
• P0506 – low idle speed if the idle speed control is blocked;
• P0507 – high idle speed when the idle speed control is blocked.

You can get acquainted with all error codes in more detail if you purchase a special book or on the official website of the manufacturer.

Cylinder misfires, causes, diagnostics, repairs

Unstable engine operation and shaking at idle, loss of power and increased fuel consumption, the appearance of a “Check” error on the instrument panel, jerking of the car and other troubles can be caused by a misfire in the engine cylinder.

There is nothing wrong with this, because if the engine runs but does not pull, it means that not everything is so critical.

Next, we will talk about how to properly diagnose a car and identify the cause of the malfunction.

How to fix the problem

To resolve the error, do the following:

1. Check the sensor for functionality. If it breaks, you simply need to replace it.
2. Make sure there is no plaque on the contact. If it is there, you need to clean it.
3. Check the operation of the on-board circuit and make sure that it has contact.
4. A random error can only be corrected by flashing the on-board computer, but to do this you need to go to the nearest service station.

So, you can solve this problem yourself, however, as practice shows, this does not always work out. It is worth noting that this code often appears in winter, if the car has been standing outside for a long time and not in the garage. It is noteworthy that it does not matter which engine is installed - 16 valves or 8 valves.

What to do if the radiator fan does not work?

As we understand, your problem is an inoperative radiator fan. If this is the case, then you first need to diagnose the expansion tank cap - make sure that its valve is working; if not, then the cap must be replaced. If this does not help, then check the functionality of the thermostat (if the lower radiator line is cold, then the thermostat must be replaced).

If these steps do not help, check the condition of the fuse. Find the mounting block in your car and open its cover - on its back there should be an image diagram with the purpose of all safety elements. If all the parts are intact, then you need to check the fan itself - it is connected directly to the battery, if it turns on when connected, this means that it is operational.

If your car has a controller for turning on the ventilation device, then it is diagnosed as follows:

1. On carburetor engines, you need to close the contacts of the regulator located in the radiator itself. If the fan is activated when closed, this indicates that the regulator is working.
2. On injection engines, the connector from the controller located near the thermostat is disconnected. Since the device is controlled by the control unit, it should be automatically activated in emergency mode. If this is the case, then this means that the regulator is not working (the author of the video is the Dmitriy Sherstniev channel).

Another possible reason could be an open circuit. Conduct diagnostics of all contacts, and also try to find a break; for this you will need a diagram, which should be in the service book.

After reading this article, many Lada Priora owners will be able to independently find and eliminate the cause of error 4. And despite the fact that special knowledge is required to decipher the error code, all the necessary information can be found in this article.

conclusions

Finding and eliminating the cause of error 4 on the Lada Kalina turned out to be quite easy. Although deciphering error codes requires special knowledge, the necessary information can be found in this article.

As in any electrical/electronics, there are no miracles, only bad contacts. If there is a sensor malfunction, then there is a circuit from the sensor to the computer. There is a malfunction somewhere.

I have a Kalina 1118, as described in the article - this is a common mistake on viburnums, but I have never had one like this, not even my friends. I myself have installed the Delta CEP, all errors are clearly described and it is not difficult to find a solution on the Internet.

Everything is written correctly. But everyone forgets what a gigantic percentage of parts are defective. Personally, only the third sensor from the store worked for me.

Error 4 appeared occasionally a couple of years ago. Then it disappeared. For the last year it has been on constantly. But nevertheless, the device on the panel shows the temperature correctly... I tried to remove it, it lights up again and again... I gave up on this matter and just drive on... All systems work fine and ok... I tell everyone that it is on because it works engine…

There are two temperature sensors in Kalina and the one that gives readings to the tidy is located a little lower than this one, which is discussed in this article...

the device on the panel (arrow) is controlled by another sensor

Perhaps the wiring connected to the sensor has broken, and hence the emergency mode with increased fuel consumption.

I have the same problem. But here's the pies... I checked everything, the whole system is working, the sensor was replaced, the fan works when it heats up. But the check is on. I'll probably have to flash it...

We forgot another option for this error to occur, it is a bad mass, or rather a parasitic influence on the computer on board due to mass from other systems. In the harness that goes to the computer there is a twist of masses, they need to be untied, as you look for on the Internet.

Hello, Vladimir Did you have such a problem when the engine overheated above normal? I changed the thermostat, pump, cylinder head gasket, but the problem does not go away.

It pops up periodically......I remove the negative terminal for 2-4 minutes. True, you have to restore the settings of the clock and radio. But in general it can be jammed... if the cooling system is working properly

For the third day now the check light is on, it shows error “4”, I reset it, then reset the terminal, but it didn’t help, it’s still on

Masses see 100%

You need to connect through the test connector and look at the real code, for me the error on panel 4 turned into code P0343.

Good afternoon, evening, morning, whatever suits you. I would like to share a little information that I have thanks to the use of a Kalina car with a simple 8-valve engine. Once... or twice... or a season... in general, I encountered a popular problem that spoils the mood of many - the car “lived its own life.” The revolutions do not float like a child. While you're driving, it seems like nothing, but if you stop at a traffic light... there's a guard. She herself holds one and a half thousand, two, two and a half. I tried everything. First, I changed two sensors at once - dhx and dpdz. Nothing changed. Then I bought the same sensors only from a different manufacturer, in the hope of thinking that they were defective (both two and only I got the fool) in general, it didn’t help either. I went to different auto specialists (we have two in total), did diagnostics, just don’t forget to fix it, as they say. I even changed the firmware. Everyone threw up their hands! And the car continued to live its own life... Then, out of my mind, I changed all the sensors in a circle, including even the DMRV (the most expensive one). But nothing has changed. I was desperate. For two months this problem bothered me - you fly on the highway, it twitches; the consumption is crazy; you drive around the city and everyone shys away from you... I started sinning on the computer... Probably the khan came to him since the problem was global, but there were no errors!))) (I’m smiling now, then I wanted to cry). Issue price 11

Common error codes for Lada Priora

Modern Lada model

Like any modern foreign car, the Lada Priora has many different sensors installed. The condition of important vehicle systems depends on their correct operation. The problem is that if some sensors fail, the Priora can continue to move. Faults of this kind can lead to increased fuel consumption, unstable engine operation, and increased wear of parts, but the car will drive, and you will only find out about the fault when it means you have to make expensive repairs.

In order not to go into the engine compartment with a multimeter, the Priora has a controller that allows you to check faults using a special tester, a plug-in or built-in on-board computer. In order to diagnose the systems, just press 2 buttons and look at the error codes.

p0504

Also, many owners of a Lada Priora with 16 valves have questions about the appearance of error p0504. She tells the owner that there is a malfunction in the brake pedal sensor. To find out the exact reason for the appearance of p0504, you need to remove the sensor and disassemble it. Pay attention to its springs, one of them could burst - replace the damaged part.

Another reason is copper contacts, which can burn. Inspect them and clean them if necessary. Sometimes error p0504 pops up due to the incorrect position of the brake pedal sensor on Priora 16. Twist it and check whether codes p0504 remain on the screen or not.

Diagnostics using the built-in BC

To view the error codes, you need to find the daily mileage reset button on the dashboard, press it and, holding it, turn the ignition key. The self-diagnosis mode will turn on. All arrows on the instruments should move from minimum to maximum values ​​and back, and all positions on the LCD display should light up. You need to look: if any position does not light up or the arrow on any device does not move, then you should check the corresponding sensors, their networks or display for malfunctions.

Priora on-board computer

In the same mode, press any button for switching modes of the built-in BC 2 times, after which digital codes may appear on the liquid crystal display:

• 2 - very strong voltage in the BS;
• 3 - errors in the fuel level sensor system in the gas tank;
• 4 - error in the coolant temperature sensor system;
• 5 - error in the air temperature sensor system outside the car;
• 6 — motor overheating;
• 7 — emergency low oil pressure;
• 8 - malfunctions in the brake system;
• 9 - battery is low;
• E - error in the data packet stored in the EEPROM.

Many drivers ask how to reset error codes on a Lada Priora. Perhaps their built-in BC is faulty, since a working on-board computer automatically exits the diagnostic mode after 30 seconds if you do not press any control buttons.

Main indicators

The Priora dashboard contains twenty-four visual elements. When the ignition is turned on, all warning lights on the dashboard turn on briefly. Thus, the on-board computer (in the future, possibly BC) checks their serviceability. This is not a mistake, as some novice car enthusiasts think.

On the Priora shield, from left to right, there are four largest elements in the form of graduated semicircles.

1. The first scale is the tachometer scale, the purpose of which is to measure the engine speed. The values ​​are shown in two colors: white (normal) and red (dangerous). If the instrument needle falls into the last gap, then the Priora’s engine is in danger.
2. The second scale is a visualization of the car's speed - the speedometer.
3. The third graduated semicircle indicates the current antifreeze temperature. If the indicator needle hits the area with red numbers, the Priora should be stopped in order to avoid boiling in the cooling system.
4. The fourth semicircular scale of the Priora dashboard reflects the fuel level in the tank. When the arrow hits the area with red scale divisions, the yellow indicator lights up. It is located slightly lower and is depicted in the form of a gas station. This means that Priora has been transferred to the reserve level of gasoline consumption.

There are two green arrows to the left and right of the speed indicator. They light up when the corresponding turn is engaged or during an emergency stop.

The following indicators are located at the bottom of the panel from left to right.

1. Check signal, or Check Engine. This indicator lights up when a breakdown occurs in the engine and displays Priora errors on the instrument panel.
2. Lights up when there is a problem with the clutch system.
3. Signals that a certain airbag is disabled.
4. Indicates that an accident has occurred with the brake system.
5. If the passenger's seat belts are not worn, this indicator will illuminate.
6. BC screen.
7. It beeps and lights up if there is a malfunction in the immobilizer system.
8. Airbag failure indicator.
9. Indicator of the operation of external lighting devices: low beam or dimensions.
10. Lights up when the high beams are turned on.
11. Failure indicator in the electric amplifier.
12. Alarm when the emergency lights are on.
13. Reset button.

Checking using a connected computer or tester

Driver Information Panel

Checking system malfunctions using connected devices gives more accurate results, but at the same time requires deciphering special codes. For example, the monitor displays code p0441 or p0130 or error p0422. Oh, these car manufacturers, in human language they could write “replace the oxygen sensor” instead of P0130 or “check the canister valve” instead of P0441. But nothing can be done, the Lada Priora is also intended for export, so it is easier to write p0441 in the program than to give explanations in Russian, Kazakh, Arabic, Armenian and 10 other languages. And then attach special tables that indicate the meaning of certain codes. Just look at them and everything will become clear. But these tables are not included with the operating instructions. Either way, you can check them out below.

All fault codes for Lada Priora car systems consist of 5 characters. Here is a breakdown of Prior's errors.

The Latin letter comes first:

• P - error in the electronic systems of the motor;
• C - error in the electronic systems of the chassis;
• B - error in interior electronics;
• U is an error in the joint operation of different systems.

• 0 - OBD-2 code;
• 1 - enterprise code;
• 2 - enterprise code;
• 3 - reserve code.

The system indicates an error

The next digit indicates the system in which the malfunction was found:

• 0 — exhaust;
• 1, 2 — fuel and air supply system;
• 3 - ignition;
• 4 - additional control;
• 5 — idle system;
• 6 - ESC;
• 7, 8 - transmission.

The last 2 digits indicate the serial number of the fault.

Deciphering faults in the fuel and air systems

• P0030 - the oxygen sensor heater wire to the exhaust gas converter has broken;
• P0031 - the same electrical wire has shorted to ground;
• P0032 - the same wire has shorted to the on-board network (BS);
• P0036 - the wiring of the oxygen sensor heater is broken, after the converter;
• P0037 - the same wiring has shorted to ground;
• P0038 - it has shorted to BS;
• P0102 - weak signal in the mass air flow sensor network;
• P0103 - very strong signal in the network of this device;
• P0112 - weak signal in the air temperature sensor network;
• P0113 - very strong signal in the network of the same device;
• P0116 - antifreeze temperature sensor signal is out of operating range;
• P0117 - poor signal from the antifreeze temperature sensor network;
• P0118 - very strong signal from the antifreeze temperature sensor;

Here we are looking for an electrical problem that has arisen.
