Life hack: Priora car adsorber valve - check, replacement, price

Remember, like on sevens and shochs, before refueling you unscrew the tank, but the cap does not unscrew. Having strained myself, I went and heard such a loud hissing, as if you were opening a bottle of beer, not just a bottle, but a keg. To prevent such hissing, an adsorber valve was invented. 10 and Priora have this system.

But it’s not just a matter of hissing; it turns out that with this hissing, harmful fumes burst out, polluting the environment. The price is too expensive for today's ecology. And more importantly, the solenoid valve for purge the canister on a Priora car saves gasoline.

After turning off the car, the system begins to work, it drives vapors through the filter and returns fuel to the tank.

The adsorber itself on the Priora consists of a carbon filter - that is, there is carbon inside. The entire system consists of 11 spare parts. The adsorber for Priora is not expensive in itself, its price starts from 800 rubles. But the whole system costs from 5,450 rubles. Replacing a valve or adsorber on a Stoda will cost from 1000 rubles. Some drivers don't see the point in this system and simply remove it. Apparently the consumption is higher, or the Priora doesn’t go with it, it just knocks, and there’s 0 usefulness from it. They simply remove the adsorber valve, and instead put a fine filter, all gases naturally escape into the atmosphere. In fact, the working system does not affect traction in any way. The Priora drove its 11 seconds and continues to do so.

In rare cases, immediately after starting the engine, the car owner may be disturbed by a malfunction of the adsorber valve. This can be confused even with more serious breakdowns that relate to the incorrect operation of the internal parts of the Priora car engine - for example, it makes a clicking noise, which, unknowingly, can be confused with hydraulic compensators. In this article we have collected signs and malfunctions of the system, so read to the end.

The built-in purge valve for the Priora adsorber is, one might say, a necessity. It is precisely because of the presence of this part that the car meets European environmental safety standards. It runs much cleaner than older cars, and the valve itself allows you to save precious drops of gasoline to release them into the combustion chamber.

The principle of operation of the adsorber on Priora

The breather is a container filled with activated carbon. Two hoses extend from it - outlet and inlet, and it itself is part of the engine power system. It operates like any storage tank: when gasoline vapors rise through the tubes from the gas tank, some of them manage to turn into liquid and flow down to the gas tank.

The second part of the vapor enters the inlet tube of the absorber and remains inside the container. They condense because activated carbon acts as a catalyst for the operation. The process occurs with the engine turned off - while the power system is at rest. After this, the fuel will be used by the engine.

The absorber valve, which operates on the principle of electromagnetic induction, is responsible for the release of fuel in the Lada Priora. The causes of malfunctions can be eliminated by simply replacing the Priora adsorber purge solenoid valve. A special absorber sensor is responsible for its movements. Like any other part that performs similar functions, it is critical to maintaining the functionality of the automotive system.

The ECU independently controls many of the processes taking place under the hood. Among his responsibilities is the preparation of the fuel-air mixture with the correct proportion. This means that the ECU must correctly use the available resources (fuel) by connecting the breather to work.

Purpose and principle of operation

Adsorber - is a container filled with activated carbon, which acts as a filter element. This element is the main part of EVAP - Evaporative Emission Control (gasoline vapor recovery system).

The system has been integrated into the fuel system of cars with Euro-2 standards and higher. Those. you won’t see an adsorber on a VAZ classic or even a 2108 model, not to mention Moskvich, Volga 3110, etc.

Standard adsorber for Priora - article number, device, price and location

The breather of the Priora car absorber is located on the top left relative to the engine cover. Replacing the absorber valve is not difficult, given that the instructions and steps are simple. Finding it is quite easy: the breather hose goes to the throttle to direct fuel in the desired direction.

Gasoline consumption will depend on the quality of its operation - the efficiency of the power system will decrease, since part of the engine vapor will be released into the atmosphere, as was the case in old cars. The VAZ-2170 catalog implies the presence of the following components in the “Gasoline Vapor Recovery System”:

• Breather (adsorber valve) - 2170-01164042-00, price - about 800 rubles.
• Hose 115 cm long - 2170-01164087-20, price - about 500 rubles.
• Hose 70 cm long - 2108-31164103-10, cost - 350 rubles.
• Hose 90 cm long - 2110-31164109-12, cost - 400 rubles.
• Hose 25 cm long - 2110-31164105-12, cost - 150 rubles.
• Steam removal tube – 2170-01164084-01 – 150 rub.
• Front steam exhaust pipe – 2170-01164244-01 – 200 rub.
• Tube – 2170-01164282-00 – 300 rub.
• Adsorber – 2170-01164010-00 – 800 rub.
• Separator – 2170-01164005-01 – 1500 rub.
• Middle steam outlet tube - 2170-01164248-00 - 300 rubles.

Where is it installed?

As a rule, the adsorber is installed under the hood on the right in the direction of travel of the car, for example, in the VAZ 2110 it is in the form of a barrel.

In other cars, it can be square and installed to the left of the engine (in the direction of travel), under the air duct (Lada Granta), the vacuum brake booster (some Nissan models) or in the radiator area. For VAZ 2114 it is located near the battery and air filter.

On the Volkswagen Passat B3, the adsorber is located under the air filter on the right side in the direction of travel.

Other vehicles - see your model's owner's manual.

What can break - malfunctions

Symptoms of a system malfunction are often associated with two parts - a purge limiter, or an adsorber sensor (price from 350 rubles).

On a Priora car, signs of a system malfunction may be as follows: While the engine is idling, the speed fluctuates. The ECU must supply the correct amount of fuel to the injector to make its operation stable. Due to a lack of data (the sensor does not work), the ECU “goes astray”.

Fuel consumption has increased. In VAZ-2170 cars there may be several reasons for increased fuel consumption. The same bad gasoline familiar to all drivers creates a real troubleshooting puzzle. Therefore, the gasoline vapor recovery system may not be related to the breakdown - pay attention to other signs of malfunction.

The check light came on

• The engine, warmed up to normal temperature, does not start the first time. This means that the "exhaust" cannot open to allow fuel to flow to the throttle, and the engine does not receive gasoline to make the first cycle.
• Engine thrust has decreased. Acceleration has become very “heavy”, and the car seems to strain when the driver presses the gas pedal harder, increasing the speed.
• The breather of the Lada Priora absorber is knocking. An unpleasant clattering sound is due to the fact that the part is simply worn out.

The VAZ-2170 car is characterized by the following breakdowns related to the gasoline vapor recovery system:

• the winding is frayed or shorted;
• wiring damage;
• mechanical damage to the valve;
• sensor malfunction.

Signs of a sensor malfunction are:

• floating idle speed;
• unstable engine operation, loss of traction;
• poor acceleration (the engine cannot take “spare” gasoline from the absorber of gaseous substances.

Specific errors must be looked at using the diagnostic connector - this way the diagnostic information will be much more accurate.

What are the dangers of a faulty valve?

Incorrect operation of the adsorber and its entire system will sooner or later lead to the fact that the fuel tank will no longer be ventilated with proper regularity. Next, a vacuum occurs, after which deformation and damage to the pump usually occurs.

When there is no ventilation of the device in question on the Lada Priora, gasoline begins to accumulate in the intake manifold. This will lead to engine malfunctions. The spark plugs become clogged, the catalyst and a device such as a lambda probe fail.

How to check the canister valve for functionality

To check the absorber limiter on the Priora, you will have to remove it. There is a difference regarding fastening. For engine 21126, the mount is a plastic casing, and for 21127 it is a mount that is located at the intake manifold. To remove a part, do the following:

1. Stop the car, lift the hood, remove the negative terminal from the battery.
2. Press the fastener of the lead wire and disconnect it.
3. Press down on the latch. After this, slide the vent up along the guides.
4. Disconnect the inlet pipe. If you can’t heat it up, pour hot water on it.

Check as follows:

1. Inspect the hoses, look for mechanical damage if any.
2. Try to fill the restrictor with air using a bulb or pump. At the same time, maintain the tightness of the small part - use clamps.
3. If air is not blown through, the part works.
4. Apply current from the battery. A click should appear as a signal to start working. When resetting the wire, you should hear another click, indicating proper operation.

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.

How to repair the adsorber and valve

Often the nature of damage to these parts is very large, since they operate under high wear conditions. The valve really shouldn't be repaired because the part is so small. But the main device often breaks down because the foam rots inside it. Coal breaks through the tubes and clogs the solenoid valve.

To repair, you will need to replace the foam separator. To do this, you will need to remove part of the gasoline vapor recovery system:

1. Open the hood, stand on the left. Stretch your hand slightly down where the gasoline vapor recovery system is located (on the left edge).
2. Clamp the two clamps that hold the separator outlet tubes. Remove the fitting tips.
3. Using a “10” wrench, unscrew the bolts securing the radiator.
4. Pull the adsorber towards you.

Why do they refuse the adsorber?

Despite the advantages of this design solution, and these are: fuel economy, absence of odor in the cabin, reduction of harmful emissions into the atmosphere (although many do not care about this), the adsorber has a number of significant drawbacks, due to which many seek to disable it or completely remove it.

Disadvantages, they are also signs of malfunction:

1. Expensiveness of the product (not for all cars). Replace or remove? More often, preference is given to the second option. For example, on an Acura MDX the price of the product varies within 10,000 rubles. For VAZ – from 800 rubles.
2. A malfunction of the device leads to interruptions in the operation of the unit: the engine does not pull (poor acceleration of the car, stalls when driving uphill, transporting goods, floating idle speed on a warm engine, if the tank is plastic, then with a clogged adsorber, constantly compressing and unclenching (in the absence of a bypass valve in the lid), it may eventually burst due to the pressure of gasoline vapors; if it is metal, then it will become deformed. One of the characteristic signs of a malfunctioning adsorber is a hissing sound when the fuel tank lid is opened, caused by the movement of air into the tank (not out) and the appearance of the smell of gasoline in the cabin, incorrect fuel level.The appearance of error p0443 (the cause of the error is a clogged or faulty solenoid valve).

Therefore, when a product fails, many people turn it off and remove it, or take a more complicated path - they open the case and replace the old activated carbon with a new one.

Components

In fact, this is a large plastic jar with activated carbon inside, because it is this composition that perfectly fights gasoline vapors. The main parts can be described as follows:

• Separator + gravity valve
• Pressure meter
• Filter part (usually carbon)
• Connecting tubes
• Solenoid valve

As you can see, there is absolutely nothing complicated. Separator - serves to catch part of the gasoline, then sends it back to the tank. Gravity valve - almost never used, but it is needed in emergency situations, for example during accidents, it prevents fuel from overflowing from the tank (for example, when a car overturns).

Purge valve failure

The valve operates on the principle of electromagnetic induction. A faulty shut-off valve, as it can also be called, makes clicking and hissing sounds when it releases unrefined vapors from the gas tank. The machine panel display includes a breakdown signal; the diagnostics carried out will accurately show the fault.

• the winding is short-circuited;
• wires are broken;
• mechanical damage.

A faulty adsorber part cannot be repaired; it only needs to be replaced. You can do this simple procedure yourself. In the latest Priora models it is located under the engine cover, and removing it is not difficult.

• disconnect the wiring;
• soften the pipe with hot water;
• remove and replace the valve;
• again use boiling water and clamp the soft tube, you can use a clamp.

• cut the hose along the edge of the part;
• install a new lock;
• heat the pipe and put it in place.

Don’t forget to attach the adsorber to its original position and flash the electronic control unit.

Why was the adsorber created?

Actually, this is a tribute to the environmental standard, namely EURO-2. Essentially this is a large filter that catches light hydrocarbons. According to the new standards, it is unacceptable for gasoline vapors to enter the atmosphere, because this contributes to air pollution.

Also, couples should not enter the car interior, because this is, to put it mildly, harmful! ON old carburetor cars, such a filter and its valve simply did not exist; the system there is a little different. BUT the carburetor went away along with the old standards, now there is only an injector and a filtration system is MANDATORY.
