Cleaning the throttle valve of a VAZ 2110: what you need to know

As you know, cars with an injector differ markedly from versions with a carburetor in terms of the design of the engine power system. This fully applies to both foreign and domestic cars.

As for the popular VAZ 2110 model, the throttle valve on the VAZ 2110 is an important and critical element that requires periodic maintenance.

Next, we will look at how the VAZ 2110 throttle valve works and works and what malfunctions the throttle assembly may have. It is also necessary to pay attention to when you need to clean the throttle assembly, how to properly clean the throttle on a VAZ 2110, etc.

Operating principle of the throttle valve

The throttle valve's job is to supply oxygen, which the engine needs to operate properly. It is with the help of this valve that the air supply to the engine is regulated during combustion of the fuel mixture. Air enters the cylinders from the environment when the valve opens, having previously been cleaned through the vehicle's air filter. The flap turns, opening the way for air, by pressing the gas pedal.

Operation of the throttle valve VAZ 2110

At the same time, the number of revolutions on the tachometer increases. In the VAZ 2110 car, the throttle control is electronic, which allows you to perform more useful work than with a mechanical type. The VAZ 2110 throttle valve is located under the hood of the car, in its central part. As a rule, it is located between the intake manifold and the air filter; all these devices interact with each other. In some assemblies of the VAZ 2110 car, it can be located on the passenger side of the car.

Several sensors also take part in the operation of the throttle valve. The main one is the air flow meter sensor. It is he who electronically controls the air supply to the engine. If there are problems with the throttle valve, it is most often the cause of failures. Also, one of the common reasons for poor operation of the throttle valve in a VAZ 2110 car is partial or complete contamination of the valve. This happens due to untimely replacement of the air filter and affects the operation of the engine - of course, for the worse.

Throttle valve of a VAZ 2110 car

Engine performance directly depends on the amount of air that comes with the fuel mixture. If the air supply is limited, the fuel mixture will not be enough for complete combustion.

Cleaning the throttle body - when to start?

For every VAZ 2110 owner, sooner or later there comes a time when it is necessary to clean the throttle valve yourself. One of the characteristic signs of its contamination is unstable engine operation. At idle, the engine may run unevenly, and in some cases even stall. When trying to start the engine, delays may occur.

Cleaning the throttle valve VAZ 2110

During normal engine operation, the number of revolutions on the tachometer in operating mode should be 900 rpm, the value should be stable. Floating speed on the tachometer, unusual sounds from the exhaust pipe - all these are also signs of a dirty valve. When driving the car at high speed, fuel consumption will noticeably increase; when driving at low speed, jerking is possible. In both cases, the car engine will work under load.

The valve becomes dirty due to oil dust and various gases. They settle on the throttle valve and can be seen with the naked eye. Since the type of throttle valve device is not complicated, you can then do the cleaning yourself without leaving the garage. To clean the VAZ 2110 damper, you need a standard set of tools, as well as any injector or carburetor cleaner - due to their chemical properties, they are all suitable for this task.

Dirty throttle valve VAZ 2110

The car's service book states that the damper should be cleaned once every 35,000 km. As practice shows, it is better to perform this action more often, at least once every 15,000–20,000 km. Cleaning the throttle body won't take much of your time, but it will significantly increase engine power. Experienced drivers constantly monitor the condition of the valve, and even if there are no problems with the engine, they remove deposits on the surface of the valve.

Let's sum it up

Taking into account the above information, it becomes clear that the throttle valve is an important element of a fuel injection engine. At the same time, it is a mistake to believe that the throttle assembly does not require regular maintenance.

Moreover, although the manual recommends cleaning the damper every 35 thousand kilometers, it is important to make allowances for the operating conditions of the vehicle. As a rule, even in cities, roads in the CIS countries are not clean, and the air is quite heavily polluted. If a car drives on dirt roads, air pollution increases significantly.

It should also be noted that VAZ 2110 car owners often do not install the best air filters. The result is active and rapid contamination of not only the filters themselves, but also the throttle assembly. For these reasons, it is optimal to change the air filter every 15 thousand km, and also clean the throttle valve (at least superficially) every time it is replaced.

It is also necessary every 30-40 thousand km. completely remove the throttle assembly, deep clean it, at the same time clean the sensors and electrical connectors, check the condition of the corrugations, pipes, etc.

Finally, we note that you need to constantly monitor the condition of the throttle and regardless of whether there are any problems with the engine. This approach will allow not only to achieve stable operation of the internal combustion engine, not to lose engine power and not to consume excess fuel, but also to increase the service life of the power unit. “Turn the Engine” is dedicated to one of the greatest blessings of civilization - the piston internal combustion engine. Everything about the operation, service and preventative maintenance of gasoline and diesel internal combustion engines. Useful information on engine and attachment repairs, methods and techniques for carrying out diagnostic procedures. Tuning, engine tuning and competent selection of technical fluids.

Superficial intervention or deep cleaning?

There are two ways to clean the throttle valve. The first is a superficial intervention that does not require complete removal of the entire device. And the second is a complete cleaning, which must be performed in cases where your car’s engine is not working well.

To perform the first type of cleaning, you will need a pre-purchased cleaning product and a fine brush. Open the hood, remove the corrugation, it goes from the air filter housing to the throttle valve. You will see a valve - it is easy to recognize by its completely round shape. Treat it with a chemical and let it sit for a few minutes, then remove the dirt with a brush. If necessary, use a rag. Repeat the procedure several more times until the flapper valve turns a bright color. This work can be carried out once every 3–5 thousand kilometers, fortunately, it does not take much time.

Removing the corrugation from the throttle valve

For more detailed cleaning of the throttle valve in a VAZ 2110, you need to completely remove the entire injector mechanism. It is also recommended to replace the gasket and O-ring, which are included in the throttle valve repair kit, which is easy to buy at any auto store. Before starting cleaning work, remove the terminals from the battery.

Then disconnect all air pipes connected to the throttle body. After this, remove the fastenings of the throttle cable and unscrew the throttle valve itself. It is attached to two bolts that are screwed into the engine housing. Electronic sensors must be disconnected carefully to avoid damaging them.

Disconnecting the air pipes of the throttle assembly

After that, take a chemical and treat the entire body and all the grooves of the throttle body. Do this until you completely get rid of the dirt. You can also clean the air flow meter sensor. To do this, carefully treat its hairs with a cleaning product and remove the dirt with a brush. Give the entire device time to dry completely before reassembling. Do not forget to change the gasket and ring, which are located in the corrugation. Also pay attention to whether all air pipes are intact. Perhaps some require replacement with new ones. For maximum effect, you can also replace the air filter.

Signs of trouble

The problem with many VAZ 2110s is that until a serious increase in speed, the car remains, as motorists say, in a “sluggish” state, it does not pull, and becomes more or less playful only when the revolutions reach approximately the 3000 mark.

This is very often associated with improper throttle operation. Moreover, the main culprit may be the manufacturer, but more on that later. And now - about some more signs of malfunction:

• engine speed fluctuates;
• there is no clear response from the car when you press the gas pedal;
• when changing gears, jerking can be observed;
• vibration is observed when the car is idling;
• stalls when changing speed;
• The engine does not start well if the car is already warmed up and then turned off.

Electronic gas pedal

On some modifications of the VAZ-2110, the throttle valve is driven by an electric motor. The idea is simple: a sensor system is installed on the pedal (most often based on a potentiometer - a variable resistor). When you press the pedal, the resistance changes, and the electronic control unit determines the position based on the signal level. Then a signal is sent to the throttle valve actuator, and it opens to a certain angle. Instead of rheostats, encoders are installed - sensors that record the angular movement of the axis. They are more accurate and reliable, but the cost is higher. In general, the reliability of an electronic damper drive is much higher than a cable drive.

Correction of a factory miscalculation

It is quite common for a throttle assembly to come out of the factory with something that cannot even be called a defect, but can still be attributed to design errors. In theory, air should flow into the space behind the throttle, for which a channel of approximately 2.5 mm is specially made.

But the whole problem is that this channel was pressed against the wall of the receiver, thus blocking the possibility of air flow. A slight modification of the throttle assembly can help in this case.

This material will help you install engine crankcase protection yourself: https://vazweb.ru/desyatka/dvigatel/zaschita-dvigatelya.html

Bored channel for air flow in the throttle

To do this, just take a file and use it to make a small groove in the indicated place. 2 - 3 mm will be enough. But before doing this, it is necessary to remove the throttle.

On a VAZ 2110, the throttle assembly is removed in the following sequence:

1. Disconnect the connectors of the sensor that regulates the position of the throttle valve, its drive cable and the XX regulator;
2. We partially drain the coolant;
3. Next is the removal of the air hose located on the body of the mass air flow sensor. Why do you just need to loosen the clamp;
4. We also loosen the clamps: where the throttle pipe is attached to the air hose; where the hose of the 2nd crankcase exhaust circuit is attached to the cylinder head cover pipe. We remove the connected hoses - the air and 2nd crankcase ventilation circuits;
5. Having loosened the clamp, remove the hose of the 1st crankcase gas exhaust circuit from the throttle assembly fitting;
6. Having loosened the clamps, we remove the hoses supplying and discharging coolant;
7. You will need a wrench with a 13mm head, with which you need to unscrew the nuts securing the throttle assembly to the receiver on a VAZ 2110;
8. It is now possible to remove the throttle assembly from the studs;
9. It remains to remove the sealing gasket and, if your VAZ 2110 has a system that traps gasoline vapors, disconnect the hose for purging the adsorber.

Even if the purpose of removing the throttle was to modify it, still do not forget that for stable operation it also needs periodic cleaning. To be honest, there is nothing complicated in this procedure, but it will help the engine run better, which is quite important.

For cleaning you will need:

• short and long screwdrivers;
• toothbrush (soft, or just old);
• cotton buds;
• cleaning agent;
• rubber or cotton gloves.

For cleaning to give the desired result, it must be carried out very carefully. First, you can go through all the cavities with a toothbrush, at the same time cleaning the idle speed control (it must also be removed). Further, more delicate, cleaning is done with cotton swabs. Pay special attention to the area where the throttle valve is located and the place where the XX regulator fits.

Please note that cleaning the crankcase ventilation duct with conventional means is not possible, but it can be easily done using the foot pump available in each trunk. The diameter of the fitting is similar to the wheel one, you just need to add cleaning agent and pump your foot several times.

If you have problems mentioned at the beginning that started recently, cleaning should fix them. If there were problems from the beginning, do not forget about improvements. Sometimes only replacing the throttle assembly helps.

Step by step cleaning

Before you start cleaning, you should prepare everything you need so that in the future you will not be distracted by searching for the right tool:

• a set of car keys, sockets and tools;
• regular and Phillips screwdriver;
• gasket for the throttle block, it is advisable to purchase a new element;
• a product that is used to remove contaminants from the carburetor;
• gloves to protect hands.

You may also need ear cleaning sticks and a toothbrush that is not used for its intended purpose.

Cleaning is carried out in the following sequence:

1. Having opened the car hood, you need to disconnect the terminals from the battery, using a size 10 key to do this.
2. By loosening the clamps on all 5 pipes, the pipe will be carefully removed.
3. The connectors are disconnected from the sensor, which is located on the damper and the regulator that controls idle speed.
4. The cable that controls the throttle is disconnected.
5. Using a Phillips screwdriver, unscrew the idle speed control to remove this element from the block.
6. Using a product used to clean carburetors, the surface of the block is cleaned. To clean the dirtiest areas, you can use a waste toothbrush and ear sticks.
7. To extend the performance of the idle air regulator and the unit, experts recommend applying high-quality silicone lubricant to the rod. If, during a visual inspection, it was noticed that the condition of the rod is unsatisfactory or there is strong play, the easiest way is to completely replace the rod with a new one, especially since its cost is quite reasonable.
8. Before assembling the throttle assembly, which is carried out in the reverse order, you need to replace the old gasket with a new one.

At this stage, the cleaning process can be considered complete, and, as you can understand, this event is not as difficult as it initially seems.
If during cleaning it is not possible to achieve smooth operation, it is recommended to contact a specialist about this problem. To determine the cause of the malfunction, it may be necessary to use special equipment, which is available only at service stations. By following the step-by-step instructions, all car enthusiasts, without exception, will be able to clean the throttle valve from contamination. If difficulties arise, you can visit the Internet resource at any time and watch a video lesson taught by experienced mechanics.

Throttle valve for VAZ 2110

What is a throttle valve in a car? This is a regulator of the patency of the channel cross-section, which changes the amount of medium, gas or liquid flowing in the channels. It is part of the design of the engine intake system. The throttle valve is an element without which the air will not be adjusted to form a fuel-air mixture, that is, the car will not operate uninterruptedly.

At its core, it is a valve, which is also called a throttle. The design consists of the following elements: the throttle itself is presented in the form of a round plate; it can rotate 90 degrees, that is, at a right angle, fixing the closing and opening of the flow. The body of the device has a complex mechanism, since it is part of the cooling system.

The throttle valves on different types of carburetors are different:

• if the carburetor has a falling current or rapid discharge, then the damper will be in the form of a rigid plate;
• horizontal type carburetor - vertical gate valve;
• in the fuel injection system - represented as a separate unit.

The types of damper drives are: electric, mechanical. It is possible to imagine an electric throttle only in modern car models. Distinctive features characteristic of this type of drive: idle speed is adjustable, there is no mechanics between the damper and the pedal. Thanks to the use of such a drive, it is possible to influence the rotating element without any effort.

To increase the reliability and strength of the element, a module with two sensors is installed. With mechanics, things are completely different. This type of drive is found only in budget cars. There is a connection between the damper and the pedal through a metal cable. We will also warn drivers that if the position of the flap valve and its position sensor is violated, this will entail the following: the speed will fluctuate, the idle speed will increase, the car will stall when the gear is in neutral, and fuel consumption will increase. If a malfunction does occur, a signal on the dashboard will definitely let you know.

Type diversity

Everyone knows two types of TPS:

1. Sample with a mechanical drive type.
2. Unit with electric drive type.

Throttle position sensor

The first type is being introduced in economy class vehicles. The complete set of elements is combined in a separate block, which includes the following parts:

• frame;
• throttle valve;
• sensor;
• idle speed controller.

As an addition, there are also pipes located here, the functional task of which is to ensure the operation of gasoline vapor recovery and crankcase ventilation systems.

The damper housing is part of the cooling system. The functional task of the idle speed controller is to maintain the crankshaft speed in the closed position of the damper when starting or warming up the engine. The IAC is a stepper motor and valve. The functional tasks of these parts are to regulate the air supply entering the intake system bypass.

In modern conditions, most manufacturing plants equip machines with electric-type dampers. These elements are characterized by their own electronic control system. Thus, the optimal amount of torque is ensured at all speed ranges and loads of the machine. In addition to increased power and dynamics, owners receive a reduction in fuel consumption and exhaust emissions.

This element includes the following mechanisms:

• Frame.
• Throttle valve.
• Electric motor.
• Gearbox.
• Throttle position sensor.
• Return spring mechanism.

Differences between the electric damper type

Main functional differences:

• Lack of mechanical connection between the gas pedal and the throttle;
• Adjustment of XX by direct movement of the damper.
• The electronic system is able to independently influence the amount of torque of the internal combustion engine. This is possible due to the absence of a rigid connection between the gas pedal and the throttle valve. This condition persists even when the driver presses the accelerator.

Such functional changes are possible thanks to the operation of input-type sensors of the control unit and the actuator. This electronic control system device is additionally characterized by an accelerator pedal position sensor and a brake and clutch position switch. Thanks to all this, the engine control unit successfully responds to sensor signals, converting them to the damper module into control actions.

Evidence of pollution

Don't forget that the throttle valve can become dirty. Signs of this are the following criteria: the engine begins to stall, lose speed, the engine starts with difficulty, at the minimum speed of the car, jerking begins. Always check the throttle assembly for causes of problems. Damper contamination occurs in many cases. Settlement occurs on the walls of the mechanism, entering the assembly due to ventilation of gases. Another reason is poor filter performance.

Remote control position sensor

The remote control position sensor can be contact (supplied as standard) or non-contact. Most often, a non-contact TPS is installed after removing the old one and discovering that it will not be possible to restore it efficiently.

This sensor on the VAZ 2110 is located directly on the throttle pipe, attached to the throttle axis.

The following symptoms indicate that the VAZ 2110 TPS needs to be checked and it needs to be cleaned (and possibly replaced):

• “Floating” idle speed;
• When the gas pedal is pressed during acceleration, the car moves jerkily;
• Increased fuel consumption compared to before;
• It is possible (but not certain) that the "Check Engine" light on the dashboard will light up.

The main danger is that if the TPS malfunctions, it will distort information regarding the position of the damper, then your VAZ will be guaranteed interruptions in engine operation, plus excessive fuel consumption.

Step-by-step cleaning instructions

If the damper does get dirty, it doesn’t matter; with the help of several cleaning steps, the car’s operation will be restored. Before cleaning, you must remove the throttle assembly according to the following instructions:

• remove the corrugation;
• turn off the power supply to the sensors;
• push out the “weight” that secures the pedal cable;
• disconnect the coolant pipe;
• remove the ventilation hose; unscrew the assembly fastening;
• Unscrew the idle speed control.

To clean mechanisms, special products are required, in most cases aerosol cans. The best solution for this task is a carburetor or brake cleaner.

Description and performance check of the VAZ 2110 throttle valve

Let's look at the example of the throttle on a VAZ 2110 car. The position of the throttle valve on a VAZ 2110 is the engine compartment. The type of drive in this car will be mechanical, we discussed this earlier. The throttle position sensor itself on a VAZ 2110 car is located in the throttle assembly; it is popularly called the “right foot sensor”.

It is used to measure the amount of throttle opening and transmits information to the car's engine block. The sensor operates on the principle of a conventional resistor. A resistor is an element of an electrical circuit that has a certain or variable resistance. Sensors can be contact or non-contact. In the car it is located on the throttle pipe and connected to the damper. The main danger is that if it malfunctions, information regarding the throttle position will be distorted.

The VAZ 2110 throttle valve and injector are important components responsible for supplying air and fuel to the engine cylinders. Many owners of this car model have a desire to check the functionality of the VAZ 2110 throttle sensor. And more than once this situation has baffled drivers. Now we will tell you about this; with the ignition on, you need to use a voltmeter to check the “minus” and the contact of the voltage element.

The reading should not be higher than 0.7 V. Then open the damper, turn the plastic sector and measure the voltage again. Now the sensor should show at least 4 V. With the ignition on, pull out the connector, check the resistance, turn the sector and see how the device readings behave. If they jump, then urgently replace the sensor, preferably with a non-contact one. Motorists say it will last much longer.

Having checked many sites for selling auto parts and comparing the cost of the throttle, we can say that the average price of a VAZ 2110 throttle body is 2 thousand rubles, or even higher. When purchasing this part for your car, do not forget to consult with the seller.

Potentiometer

In other words, the potentiometer changes the opening angle of the damper and thereby affects the controller. When the damper is closed, the voltage does not exceed 0.7 V, and when fully open it reaches 4V. This is how fuel supply is controlled.

If the throttle valve stops responding to impulses emanating from the position sensor, the following breakdowns may occur:

• Floating speed when the engine is running. Increased idle speed;
• The engine stalls when switching to neutral;
• Uncontrolled fuel consumption;
• The engine is running at half power;
• The CHEK light is on - check if the throttle valve is working correctly.

Throttle assembly VAZ 2110 | VAZ 2111 | VAZ 2112 - removal and installation

RECOMMENDATION The throttle assembly on VAZ 2110, VAZ 2111, VAZ 2112 vehicles can be removed without draining the coolant. This will require two M10 bolts as plugs.

WARNING Start work only after the engine has cooled down to a safe temperature (not higher than 45°C).

Removing the throttle assembly

1. We prepare the car for repairs (see paragraph 2a Preparing the car for maintenance and repair). 2. Remove the wire terminal from the negative terminal of the battery (see paragraph 2 Battery - removal and installation). 3. Remove the decorative trim of the engine (see Decorative trim of the engine - removal and installation). 4. By unscrewing the expansion tank cap, we relieve excess pressure from the engine cooling system. 5. Remove the air supply hose to the throttle valve. 6. Disconnect the throttle valve drive cable from the sector (see paragraphs 3 and 4 Throttle valve - replacing the drive cable) 7. Disconnect the wire connector from the TPS (throttle position sensor). 8. Disconnect the wire connector from the idle air control (see paragraphs 2 and 3 Idle air control (IAC) - check and replacement). 9. Use a Phillips screwdriver to loosen the clamps securing the crankcase ventilation system hose and two coolant supply hoses. . and adsorber hose.

14. While holding the throttle assembly in a raised position, remove the coolant supply hoses from the throttle body fittings. 15. Insert M10 bolts into the hoses. To prevent them from falling out, tighten the hose clamps.

Throttle assembly installation

We install the throttle assembly and all the removed parts on the car in reverse order.

useful tips for motorists

Alternative replacement

Sometimes there are cars with parallel installation of 2 TPS. In a functional sense, such installation will not add any power, but if one unit fails, the second one will operate uninterruptedly. Therefore, the introduction of two TPS is carried out in order to increase the reliability of the module. These elements can be either non-contact type or sliding contact type. As an addition, this module design includes an emergency damper position, which operates thanks to a return spring mechanism.

Do-it-yourself cleaning of the throttle valve on a VAZ 2110

The throttle valve is an integral part of almost any car. The domestic masterpiece represented by the VAZ 2110 is no exception.

It is noteworthy that there is no place for a car without a throttle valve, but it is this valve that often causes a lot of trouble to the car owner.

Most often, problems with the throttle manifest themselves in the form of incorrect operation of the gas pedal, strange behavior of revolutions when accelerating or driving on the road. The first thing you need to do is check if everything is fine with the damper.

Unit design

In simple terms, without terminology unnecessary for most motorists, the throttle valve is nothing more than the gas pedal of your car.

By pressing or releasing this pedal, you thereby close or, on the contrary, open this damper.

The device provides a path for additional air to enter. When you press the gas pedal to the floor as much as possible, you open the throttle fully, so the engine speed increases.

Location

Debugg

If you notice that the throttle has begun to perform its direct duties poorly, do not rush to go to a service station and hand over your money.

The problem with the damper can often be solved with your own hands.

Most often, a problem with the throttle occurs due to contamination, which leads to impaired functionality. To correct the situation, simply clean the element.

When Cleaning Is Required

The practice of "tens" car owners shows that on these cars the throttle becomes clogged literally just a few years after the start of active use of the car.

The biggest “pests” for the damper are particles of oil, dust and gases coming from the engine crankcase.

When the engine is running, dust mixes with air and oil, forming a kind of mixture that enters the throttle valve. Over time, this substance sticks to surfaces and accumulates on the idle rod.

Soon the thermal gap becomes covered with dirt, and access through the idle air regulator channel is significantly deteriorated. If you do nothing, the engine will begin to work incorrectly, the dynamics will drop, and the engine will respond late to pressing the gas pedal.

Signs of contamination

Problems with the throttle valve can be identified by characteristic symptoms.

Signs

Explanation

Engine has difficulty returning from high to low speeds

This happens when you take your foot off the gas pedal. Instead of a smooth return to the required parameters, the speed literally drops to the 400 rpm mark. The engine may stall and begin to shake. The speed can return to the desired level, but with difficulty

The engine is difficult to start when cold and even when operating temperature is reached

To start the engine normally, you need to turn the starter for a long time. You can identify the problem by smell. The characteristic aroma of unburned fuel will come from the exhaust pipe. Try pressing the pedal all the way down several times. This will open the throttle fully, air will flow in, and the engine will start. But in the first few minutes the engine will still stall

Troubling the motor is a rather indirect sign, since this is how the engine can behave in various types of failure. But don't rule out problems with the throttle.

Repair work

Now to the question of how the cleaning procedure is performed. For everything to go smoothly and without problems, it is enough to prepare all the necessary materials and tools in advance, place everything at hand and get to work.

To clean the throttle you will need:

• Screwdriver Set;
• 13mm wrench;
• Throttle valve cleaner.

Specialized preparations made from appropriate components are sold specifically for these purposes. Do not spare money on their purchase, since the funds will last for a long time. This is more profitable than changing the damper every time.

Cleaning with special means

Preparation

Let's start with the preparatory activities that will ultimately allow you to get to the throttle body and more and clean it properly.

1. Remove the casing that is installed on the power unit.
2. Unscrew the cap on the expansion tank. This will allow you to relieve excess pressure from the cooling system.
3. Slightly loosen the tension on the mounting clamps, then remove the forced ventilation tube.
4. Examine the current condition of the air pipe, which should also be removed and, if necessary, replaced.
5. If there are significant traces of oil in the pipe, then you can be 100% sure that the throttle is definitely clogged.
6. The problem is most likely in the forced ventilation duct. This is explained by the fact that contaminants in the form of gas from the crankcase and oil particles have no other way than through the ventilation branch.
7. Next you need to remove the damper heating tubes. To do this, just loosen the clamps with a screwdriver.
8. For a while, come up with plugs for them from improvised means - old spark plugs, some kind of non-hollow rubber bands. In short, anything that fits the diameter of the hole.
9. Remove the fuel tank ventilation system hose. To do this, you must first unscrew the clamp, remove the cable and unscrew the throttle mounting nuts.
10. Be sure to remove the connectors from two sensors - idle speed and throttle position. They are located on the unit being repaired, so there will be no problems with the search.

There is nothing difficult about cleaning the throttle valve. This procedure can be easily done with your own hands, without involving specialists from car services and without spending extra money.

• Using the purchased throttle cleaner, clean the channels and the entire disassembled assembly;
• Rinse the engine's forced crankcase ventilation duct especially carefully, since this is where the largest amount of pollutants comes from;
• Use sharp objects if you want to carry out the work responsibly and as thoroughly as possible. A simple knitting needle will do;
• Remove the idle air control. To do this, simply unscrew a couple of bolts;
• Be sure to wash the unit thoroughly;
• Check the condition of the rod. If it is heavily soiled or there is play, the element is easiest to replace. It's not expensive;
• Inspect the current condition of the gasket. If the gasket is damaged, be sure to buy a new one. Even if it is in satisfactory condition, we advise you to make a replacement once you have begun to dismantle this unit;
• After washing the throttle assembly elements, return all its components to their places, proceeding in the reverse order.

Cleaning result

If you follow the recommendations, use special cleaning products and do not rush, after the washing procedure all problems with the gas pedal will disappear, the engine will again clearly respond to your “commands”.

As you can see, cleaning the throttle is quite simple. The most difficult stage can only be called disassembling the unit. And then, in the confident hands of a master, even a beginner, everything will go smoothly and without mistakes.

conclusions

Dismantling the intake manifold of a 16-valve VAZ-2112 is quite easy and simple. Of course, it’s worth understanding at least a little about the design of the main power unit, but if desired, any car enthusiast can remove this unit.

Since I removed the flap for flushing, I decided to immediately replace the gaskets on the receiver; it is not known when they were changed before me. The procedure for removing it can be found on the Internet, but it’s a pleasure to remove it (((. At first I couldn’t feel the nuts, because I didn’t know where they were))) Then I couldn’t unscrew it because everything was stuck.

And then I couldn’t remove it because the breather pipe didn’t want to come off until I pryed it open with a screwdriver. He became like a stone. In general, in addition to the gaskets, I had to change both the breather and the oil dipstick seal.

Gaskets cost 65 rubles. , I’ll tell you right away, buy silicone ones, rubber ones are very difficult to install and they don’t last long.

The pipe and clamps and seal cost about 300 rubles.

Now the most interesting thing is that when I took it off, I was a little freaked out) the rubber bands were burnt out, there were some deposits in the receiver itself, there was generally some kind of dirt in the back that couldn’t be picked with a screwdriver. And there’s some kind of crap in the block, blackness, dirt, yuck... how could the car get like this? Now I have to do it! In general, look at the photo!

Full size These are gaskets, as if they were cauterized on one side

Full sizeBreaker who didn't want to take off

Description of the engine structure, the procedure for repairing the power unit of the Lada 2110 car, the stages of assembly and disassembly of parts of the Lada 2112 cylinder head, adjusting the engine valves with your own hands VAZ 2111, VAZ 2112, VAZ 2110. Maintenance of the engine of the Lada 2112 car. Instructions for repairing the cooling system, exhaust exhaust gases, power supply of the Lada 2111. Features of the 8 and 16 valve engines of the Lada 2110. Operation of the main components and assemblies of the engine Remove the plastic engine shield and disconnect the high-voltage wires from the spark plugs (see Replacing spark plugs for VAZ-2111, -2110 engines). Disconnect the throttle assembly from the receiver (see Removing the throttle assembly) and the throttle drive cable. We disconnect from the receiver the vacuum supply hose to the electro-pneumatic valve of the VAZ 2110... ...and the hose of the vacuum brake booster of the VAZ 2112.

Using a 10mm socket, unscrew the two nuts securing the VAZ 2112 receiver to the cylinder head cover supports.

Using a Phillips screwdriver, loosen the clamps securing the couplings connecting the receiver to the intake manifold.

We remove the VAZ 2111 receiver. Use a 10mm wrench to unscrew the bolt securing the guide tube of the oil level indicator of the VAZ 2112. To remove the intake manifold, use a 13mm socket to unscrew the five nuts securing it to the cylinder head of the VAZ 2110.

We remove the intake manifold of the VAZ 2112... ...and the manifold gasket. We install the VAZ 2111 intake manifold and receiver in the reverse order.

None Prepare a standard set of tools and perform the following sequence of actions:

1. Remove the plastic engine shield and disconnect the high-voltage wires from the spark plugs (see “Replacing spark plugs”). We disconnect the throttle assembly from the receiver (see “Removing the throttle assembly”) and the throttle drive cable (see “Removing the throttle drive cable”).
2. Disconnect the vacuum supply hose to the electro-pneumatic valve and the vacuum brake booster hose from the receiver.
3. Using a 10mm socket, unscrew the two nuts securing the receiver to the cylinder head cover supports.
4. Using a Phillips screwdriver, loosen the clamps securing the couplings connecting the receiver to the intake manifold.
5. We remove the receiver.
6. Using a 10mm wrench, unscrew the bolt securing the guide tube of the oil level indicator.
7. To remove the intake manifold, use a 13mm head to unscrew the five nuts securing it to the cylinder head.
8. Remove the intake manifold and manifold gasket.

At this point, the repair work to remove the receiver and intake manifold on the VAZ 2112 engine has been completed. Install the intake manifold and receiver in reverse order.
