Throttle valve gasket VAZ 2114 8 valves injector

As is known, fuel-injected cars use many sensors that are necessary to monitor and control the operation of the engine. To operate an internal combustion engine, you need not only fuel, but also air, and the accelerator pedal actually regulates engine speed by supplying air to the cylinders. The more air entering the cylinders, the more fuel is needed for the correct fuel mixture ratio.

In injection cars, which is the VAZ 2114, a special unit called a throttle valve is used to regulate the air.

This article talks about the VAZ 2114 throttle valve, namely its purpose, design, signs of malfunction, cleaning and removal.

General characteristics

If we consider the throttle assembly as a whole, it will consist of several parts:

• coolant outlet and supply pipes;
• ventilation system tube;
• a sensor that controls the position of the damper;
• RXX;
• the damper itself;
• condensation system pipe.

Knowing the throttle structure and what it looks like is necessary for cleaning. This unit is one of the most important components of the intake system. When the throttle operates correctly, a sufficient amount of air is sent to the engine, which is used to enrich the fuel mixture. The damper is controlled by an electronic gas pedal, which, when pressed, changes the opening angle.

This mechanism is located between the intake manifold and the air filter. Getting to it for preventive cleaning will not be difficult even for someone who has just become a car enthusiast.

To work, you will need to prepare tools and materials for cleaning.

Signs of damper contamination

The car itself may tell you that it’s time to start cleaning the damper. To do this, you need to listen to the engine. A few main signs:

• when the e-gas pedal is released, the engine speed decreases jerkily;
• difficulty starting in winter;
• When starting, a strong smell of gasoline may be felt in the garage;
• at the beginning of operation, the engine stalls, since not all cylinders start at the same time;
• the car jerks during acceleration;
• it is impossible to brake with the engine and coast;
• when switching to low speeds, the car may stall;
• When driving at low speeds, shocks are felt.

The appearance of these symptoms is due to the fact that insufficient air enters the engine and the fuel mixture becomes poorly enriched. Due to the design features, combustion product residues accumulate on the damper - unprocessed fuel, soot, drops of oil. Dust and small particles of sand are added to them from the air supply system, which makes the mass very thick. The intervals between preventive cleanings are shortened by poor quality fuel and engine oil.

When the layer of dirt becomes thicker, the damper cannot move smoothly, and its opening angle becomes smaller. Because of this, the amount of air entering the cylinders is reduced and engine power is reduced.

Symptoms of DZ malfunction

The throttle mechanism quickly becomes dirty due to the fact that it is located in direct contact with combustion products. Plus, during the operation of the car, natural contamination of the internal protection occurs with various inclusions that enter through the filter membrane. Dust and dirt reduce the movement of the damper, the thermal gap decreases, and in turn the channel capacity decreases.

You can understand that the throttle valve needs cleaning by the following signs:

1. During frosts, starting the VAZ-2114 engine is very problematic, and when starting the engine you can’t hear the smell of exhaust gases. In a closed room you can often hear the strong smell of gasoline.
2. Due to the lack of air-fuel mixture in the engine cylinders, vibration occurs when the power unit is started, and at low speeds the vehicle jerks.
3. There is no smoothness when releasing the gas pedal and when switching from high to low speeds.

If similar symptoms of a malfunction begin to appear, then it is likely that the throttle mechanism has reached its critical level of contamination and requires prompt cleaning.

Step-by-step instruction

Before starting work, purchase a special cleaner for carburetors, and also prepare a set of screwdrivers and a 13mm wrench. If you want to get to the hidden places of the damper, then also take cotton swabs. When disassembling it often turns out that the reservoir o-ring and throttle body gasket are unusable, it is best to replace them at the same time as cleaning, so that later you do not have to waste time disassembling the assembly again. You need to purchase parts based on engine size and number of valves. The gaskets for 1.6 are slightly different than for a motor with other parameters.

1. Lift the hood and remove the plastic cover from the engine. If you have not a mechanical, but an electronic damper, which was installed on cars of later years of production, then remove the terminals from the battery and disconnect the electronic damper control chip.
2. Disconnect the rubber ventilation hose. This hose is held in place by a clamp, so you will need a screwdriver. If you see dirt in this part of the assembly, wipe the connections and components with a rag.
3. To reduce the pressure in the cooling system, remove the liquid supply tubes from the throttle assembly. To do this you will need to loosen the clamps. To prevent dirt from getting into the cooling system, plugs are put on the tubes. There you can do with all the hoses.
4. Lastly, remove the fuel tank ventilation hose.
5. After this, it is enough to unscrew two bolts and disconnect the accelerator pedal cable to get to the damper.

Examine the part and decide how you will proceed next:

• carry out superficial cleaning without removing the entire assembly;
• completely remove all contaminants, replace the gasket and o-ring.

In the first option, you need to remove a layer of dirt using a rag or cotton pad from the surface of the damper.
In this case, do not use specific cleaning agents - wipe the throttle with gasoline or ordinary solvent. When cleaning, manually adjust the flap to remove dirt not only from the outside, but also from the inside. For complete cleaning, remove the throttle assembly. To do this, it is enough to remove two bolts with a 13mm wrench. In this case, complete cleaning is carried out with special means and consumables are replaced. After you finish work, be sure to blow out the assembly with a stream of compressed air. Thanks to this, you will get rid of excess moisture in the assembly. With complete cleaning, your manipulations take place in a non-confined space, which allows you to put the entire unit in order. This is exactly what is best to do if you are doing routine throttle maintenance. During the complete cleaning, be sure to pay attention to the idle speed sensor - it is best to remove dirt from it using WD40 and cotton swabs.

Preventative cleaning of the part

In order not to wait until the VAZ 2114 throttle completely stops functioning, it is necessary to carry out surface washing of the part. This cleaning method is very simple. But do not forget that by performing such an operation, you will only clean some parts of the damper from dust. Consequently, the work will not be of much use. However, superficial cleaning will be an excellent start for VAZ drivers who have no experience in servicing the throttle valve.

Surface washing of the part

For preventative cleaning, it is necessary to remove the corrugation from the surface of the part. Next, we spray the internal parts of the damper with a cleaning agent, after which we thoroughly clean its structure with a rag or brush. The same must be done on the reverse side of the throttle valve. After this, install the corrugation and close the hood of the car.

Installing the throttle body corrugation

This cleaning method can be performed every 20–30 thousand km. In this way, you will significantly reduce the clogging of the element and extend its service life.

Cleaning the throttle valve on a VAZ 2114 in two ways

Flushing the throttle valve is not a troublesome procedure. Especially if you have already had to remove the throttle and put it back. For those who are hearing about such a unit as a throttle for the first time, I’ll explain: on the fourteenth, as well as on the fifteen and ten, this damper is located in front of the intake manifold.

The main function is to regulate the amount of air that enters the manifold. It is clear that the fuel entering the cylinder burns only when mixed with air, therefore, the more of it, the more active the combustion is, the engine produces more power, and the car drives faster. Everything would be fine, but only if there is more air, then in proportion to it more gasoline will flow in and be burned. But this is not always required. And this same throttle controls the inlet for air flow, thereby controlling the power produced by the engine and the speed of the car.

The valve opens and closes at the moment when we press the shoe to the floor - the gas pedal - or release it (the throttle valve is connected to the gas through a cable).

As has already been said, you don’t need much experience in the process of how to clean the throttle valve; it is much more important to realize in time that it needs it. Experienced drivers and service specialists unanimously insist that every 60-70 thousand kilometers it is necessary to carry out preventive maintenance along with diagnosing the condition of the damper.

Car service nuances

It's no secret that many car owners prefer repairs at service stations. There are many reasons for this.

But there are several nuances that should be taken into account when visiting a service station.

1. In addition to cleaning the damper, the technicians will begin to assure you that additional cleaning of a number of components is required, as if without this the repair will not be complete and the effect will not be achieved. All this is a banal attempt to charge you more money for unnecessary work.
2. They may start telling you that the damper is cleaned every 15, or even 10 thousand kilometers, they will offer their services, maybe even provide a discount as a regular customer. Again, the simplest trick. This figure is completely untrue. The frequency of cleaning the throttle valve on a VAZ 2114 car recommended by the manufacturer is 60-70 thousand kilometers. But in practice it turns out to be about 50-60 thousand kilometers. You just need to monitor the condition of the unit and pay attention to the symptoms of contamination that we have already introduced you to today.

Whether to do the work yourself or have it done at a car service center is entirely up to you. The most important thing is not to let the problem get worse, as it can result in really expensive repairs.

When is it needed?

Dust, oil, crankcase gas - all these are reasons why we have a dirty throttle valve. Slag settles on the walls of the entire assembly and prevents complete response to the pedal of the damper itself - it will no longer open and close efficiently. It will easily become clear to you that the time for cleaning has come, based on the following symptoms:

• The engine starts every other time
• Increased crankshaft speed
• RPM fluctuates at idle
• The car jerks if you drive at low speed
• The engine may start and immediately stall

Cleaning has never been superfluous, but along with this procedure, just in case, check the condition of the air flow, idle speed and throttle lift sensors.

Signs of a dirty remote control

The most common symptoms associated with a dirty damper:

1. Poor engine starting.
2. Unstable idling, speed fluctuates.
3. The car jerks when driving at low speeds.
4. Difficulty idling, engine stalls.

All these signs indicate a dirty remote control. But do not rush to draw conclusions and start cleaning the unit, because they may also indicate a breakdown of some sensors: IAC, TPS - they are located on the throttle assembly and may be faulty. In particular, high-quality washing of the remote control can cure them, but not a fact (by following the link, you can check, clean, replace the IAC, check the TPS, repair and replace it). A faulty mass air flow sensor also has similar symptoms. It is advisable to clean the remote control at intervals of 30 thousand km.

Washing methods

On a VAZ 2114, cleaning the throttle valve can be done in two ways: surface and deep washing.

Surface washing method

This method is easy and does not require knowledge of how to disassemble the throttle valve on the fourteenth. But the effect from it is insignificant - we walked superficially with a rag over the body of the unit, wiped off the dust and that was it. But even in this case, you need to have a small arsenal: a cleaning agent - the good old WD-shka will come in handy (many people believe that this is the best product for cleaning the throttle body), but you can also take alcohol, gasoline, carburetor cleaner, a rag and a brush. The process is like this:

1. Removed the corrugation from the damper
2. Sprayed all the insides of the assembly with cleaning agent
3. Went through with a brush
4. Wipe it off with a cloth
5. The main thing is not to forget that the reverse side of the unit also needs to be cleaned - open the flap
6. Then we put everything back in place - and that’s it!

Surface method from the word “surface”, the internal parts of the unit with this method of cleaning remain dirty.

Deep washing method

The method requires a more thorough approach, a little experience in removing the damper and a richer arsenal for cleaning: a cloth with a WD head remains, plus a cross-head screwdriver, a throttle valve gasket (if the engine is 1.5 liters) and a receiver O-ring (if the engine is 1.5 liters). 1.6 l) - an inexpensive pleasure, on average 40 rubles, cotton swabs, a 13-socket wrench and 2 M13 bolts. The process is as follows:

Removing the throttle valve on a VAZ 2114

• We remove the throttle assembly: pull the corrugation off the filter, then disconnect the pipes with antifreeze (for this procedure you need the same M13 bolts to plug the pipes; many recommend draining the antifreeze, but this is a waste of time, just very quickly disconnect and plug the ends), Next, you need to remove the adsorber pipe.
• All the hardest part is over, we move on to disconnecting the fasteners of the assembly itself, then disconnect the gas pedal cable and remove our assembly.
• As soon as the assembly has been removed, we disassemble it: let's start with the IAC and TPS sensors.
• They need to be washed thoroughly.

• Then wash the damper on all sides, after washing, blow through all the holes so that everything is dry.
• We assemble the assembly in exactly the opposite order and put it in place.

Superficial cleaning

This method does not require complete disassembly of the mechanism. All you need to do is run a cloth over the damper and remove the surface layer of dirt. We will arm ourselves with any cleaning agent (alcohol, solvent, gasoline, wd-40), since they differ only in how much effort will need to be put into cleaning. You will also need a brush and a cloth.

You need to remove the bellows of the air purification filter and spray the hole in the throttle valve with cleaning agent. Clean the splashed surfaces with a rag. If it doesn’t rub off well, use a brush. It is worth noting that the inner surface of the damper is also dirty, so it also needs to be cleaned after opening it. That's the whole procedure for removing plaque. We install the device in the reverse order of removal. However, such cleaning does not provide access to all surfaces of the mechanism, so if it is heavily soiled, you should use the full cleaning method.

Cleaning the idle speed sensor

It is very important to pay special attention to the condition of the idle speed sensor. Since it plays an important role in the throttle assembly, and if this sensor is faulty, then the engine will behave inappropriately, and you will sin on the throttle. But this is not even the worst thing - a malfunctioning sensor always means excessive voltage on the entire system of the car and its incorrect operation, which is dangerous, especially at a VAZ, where sometimes it is not possible to figure out what caused the problem.

Knowing how to clean the throttle valve, we clean the IAC sensor. The only thing is that if you have the fourteenth with a volume of 1.6, you will first need to unscrew the two nuts securing the throttle assembly to the receiver and move it away with a gap of a couple of centimeters, without removing it from the car. The process for cleaning the sensor is as follows:

• You need to remove the entire wiring system from the sensor.
• Dip a cotton swab into the WD solution and carefully clean all these contacts.
• Then use a cross-head to unscrew the sensor fasteners (if they are present, of course, if they are not, the IAC is sitting on the varnish and you cannot do without removing the entire assembly).
• The sensor can now be pulled out and inspected - if it is all oily and covered with a layer of dirt - the VAZ 2114 throttle valve has long been in need of deep washing, just like it.
• Take a WD-shku and spray it onto the needle of the cone with a spring, wipe off the corroded dirt with a cotton swab. Just like the entire assembly, you need to blow it out after washing and put it back in place dry.

• Now check the distance from the sensor cone needle to the body - it should be 23 mm!

That, in principle, is all that concerns the process and reasons why you should clean the throttle valve. It is important to understand the fact that if after deep cleaning of the damper and sensors. The higher fourteenth still behaves badly, twitches and stalls at idle, then the problem is not in the throttle or in the sensors (most likely). Perhaps the wiring is loose.

By the way, if you still decide to go to the service center to the craftsmen so that they wash and clean everything for you, the pleasure is relatively inexpensive, on average 500 rubles. Advice - the throttle is the only thing they should clean, without touching your brain about the topic of why they clean the throttle and how often it should be done. It’s no wonder that the more often a client visits the service, the better the business goes. They may say that flushing should be done once every 10-15 thousand km; this is too small a figure and not realistic in practice.
