If your aircraft air sensor died, then do not hurry to change it. Try to clean it, perhaps it will help you and save considerable money in your pocket.
Opinions about the flushing of DMRV are ambiguous: someone says that the flushing of DMRV helps, someone just scares the sensor, using this method. Our opinion is that the sensor can be washed, but very neatly, because DMRV is very sensitive, complex and sensitive. And you need to wash not all the plate, but a small rectangular window under the arrow of the air direction. There is an anemometer and very subtle contacts suitable for it. These contacts are very sensitive and easy to break and dissolve.
Therefore, for washing it is strictly forbidden to use:
- compressed air;
- ether;
- ketones;
- matches, cotton wands;
- acetone content aerosols.
Regarding the cleaners of the carburetor, the opinion is also not definitely, because For example, in the Skoda service center, they write that the sensor is washed precisely the carburetor cleaner. But I would not risen, because DMRV is the most expensive of all sensors.
What to clean DMRV?
To clean the sensor, we still have the well-known WD-40 and "liquid key".
Their composition includes diesel fuel with heavy fatty acids, so they leave the film. This film can be washed with alcohol: ranging from methyl, ending with ethyl and isopropyl. Of these, it is necessary to make a mixture with distilled water in the ratio of alcohol / water 5 to 1. Do not use alcohol sold in the host. products, - he is dirty. An ideal flushing solution will be isopropyl alcohol with a temperature of 55-75 degrees.
Cleaning DMRV on VAZ.
For the so-called DMRV repair we will need:
- cleaning and flushing fluids;
- syringe;
- shutter flat.
- Remove DMRV. To find out how to remove DMRV, read the article
- We unscrew the sensor element that is attached on two special bolts. Such bolts can be unscrewed by the usual flat scolding.
- We take a syringe with liquid and at a distance of 5-10 cm. I splash on all parts of the sensor: contacts, diode, holes, etc.
- For prophylaxis, clean the wire connection block and their contacts.
- We rinse everything as a syringe and give dry.
- Install and check.
- If it does not help, the process can be repeated again. If the sensor does not work anyway, you will have to buy a new one.
At the failure of the sensitive element of the mass flow sensor (DMRV), it will take expensive repairs. To such damage, it most often causes contamination of this instrument: it cannot adequately estimate the amount of the necessary air, the composition of the combustible mixture is disturbed and, ultimately, the operation of the entire engine. Cleaner DMRV Liqui Moly, created by the famous German auto chemical manufacturer, allows you to bring the sensor in order and do without repair.
Description
Liqui Moly Luftmassensensor-Reiniger - a special blend of cleaners in a convenient aerosol form. Easy to use, economical. Removes different kinds of contamination on the sensor, cleans the sensor. When this device is contaminated, a combustible mixture is incorrectly formed, which leads to problems with the launch of the motor, idle disorders. The engine power drops, can give automatic transmission.
If the problem is only in the contamination of the sensor, then the cleaning fluid is able to correct the situation and help avoid expensive repair.
Properties
Liquima moth PMRV Purifier has a number of useful properties:
- fast and high-quality cleansing;
- simplicity and ease of use;
- economical flow;
- high evaporating ability;
- fast full evaporation;
- security for DMRV.
Thus, this tool allows you to solve many problems with a time, avoid vain waste of money. AND positive reviews Motorists confirm this.
Specifications
Application area
Washing is suitable for cleansing wire and film air flow sensors. It can be used in vehicles working both on gasoline and diesel fuel.
Instructions for use
The instruction on the use of this fund does not differ in difficulty:
- Disconnect the electrical switch from the sensor.
- Remove the sensor from the engine.
- Spray the means to the DMRV sensor.
- Wait when dissolved pollution of the glasses.
- Seeing the sensor completely.
- Install it back.
Do it need as needed or when replacing air filter. Before using the spray to check its action on plastic on a small area of \u200b\u200bthe body of the device.
IMPORTANT!
You can not touch the sensor sensor with hand or tools during dismantling. This can lead to its failure.

What a cleaner will kill DMRV, and what is safe for DMRV - see yourself. I put an experiment with cleaners and decided for myself how the cleaner can clean the DMRV, and what it is impossible. And you decide for yourself - the choice and decision is purely individual.
In the experiment participated:
- 2 carburetor cleaner, one of whom I called for myself "conditionally safe" for cleaning DMRV, because of the inscription on the can oxygen sensor »
- Special liquid for cleaning DMRV
- Liquid to facilitate work with threaded compounds
- Plastic bath
- Sensor DMRV
- idle sensor
- throttle knot
In the end, I cleaned everything I need.
The result is excellent, it is shown at the end of the video.

I got a question: what to clean the sensor (SENSOR) (DMRV) Mass Air Flow Sensor (MAF). Sensor (Sensor) is very gentle here this sensor (Sensor MAF) Bosch from Lada Niva 4x4 other cars Sensors are also such gentle alone weaker, other less weak all sensors (Sensor MAF) cost $ 200 and more many masters in YouTube are advised to clean DMRV (Carb Cleaner) carburetor liquid (Carb Cleaner) carburetor cleaning, carburetor fluid (Carb Cleaner) There are carburetrators (Carb Cleaner) Conditionally safe. They have an inscription on a cylinder. It is not damaged by an oxygen sensor for others. There is no inscription Sensor For example, this composition is not written, the manufacturer's secret information. But the smell of acetone is the composition of this cleaner in the previous video, I told and showed about the components of this cleaner, too, you can only tell now about WD 40. This WD 40 it turned out to be completely accidental, the Master advised to clean ( Sensor MAF) With the help of WD40, it turns out it is very strange. The fact is that the WD40, on the contrary, is designed to lubricate the film against corrosion, rust, what we want to get rid of what was the DMRV (Sensor MAF) is clean, without an oil film dry, almost low-fat this cleaner smells a medical alcohol.
Splazgal, poured onto the plastic bath until the alcohol did not heat the plastic. All well plastics did not melt it. This is not an aggressive fluid can not be afraid and clean the DMRV Mass Air Flow Sensor (MAF). This liquid with the smell of acetone This plastic spatted by carburetors cleaner (Carb Cleaner) Abro I did not make a long form and wait until melted plastic Believe this place was melted from the Abro cleaner if the acetone smells, it means there is acetone plastic dissolved in 2 minutes completely bath dissolved this safe Carburizer Cleaner (Carb Cleaner) I splashed here safe Carb Cleaner a little better plastic was melted longer but a bath still melted an aggressive environment still eating less aggressive than Azeton ABRO but it will not save DMRV Mass Air Flow Sensor (MAF). Both carburetors cleaner (Carb Cleaner) melted plastic in 5 minutes plastic dissolved strongly.
It became from Carb Cleaner Bath 5 minutes after processing this "safe" carburetor cleaner (Carb Cleaner) What are the conclusions? When choosing cleaners, it should be borne in mind that chemicals of many cleaners can spoil the DMRV Mass Air Flow Sensor (MAF). Need to think what fluid to clean? Price cleaner Different about the price I spoke in previous video Choose I cleaned the sensor (Sensor). A special cleaner for DMRV (MAF) Liqui Moly's excellent result, has become a clean this throttle node (Throttle Body Injection) I cleaned the carburetor cleaner (Carb Cleaner) The magnificent result was very clean yet cleaned the idling sensor (Regulator Idle) I am sure that the cleaners are necessary Apply by their intended purpose, according to the instructions it is not necessary to experiment, especially DMRV Mass Air Flow Sensor (MAF) is expensive more than $ 200 Choice for you to make a decision. Goodbye.

Good day! VAZ2114, 2011 G.V. Now there has been such a problem on the traffic light, I begin to touch, and the turns as they were 900 and stand, they do not respond at all on the gas pedal. It happens on the contrary, how to jump until 2000-2500 and do not fall, you have to join the car and re-start. What is the problem? What to change? I have an electronic gas pedal. Tell me what to do. For previously thanks !!!

Andrei, thanks for your video. We look with pleasure. A small remark on carburetor cleaners - safe for oxygen sensor is safe for lambda probe, because Oxygen sensor is it. To clean the DMRV, I do not recommend using carburetor cleaners at all. Instead of Liquimolly, often use isopropyl alcohol at a small pulverizer pressure. The effect is the same.
in 90% of cases, the car wash will not help, there is a subtle active spraying that over time can steal the arriving garbage from the air intake. Very often this happens when using "zulevikov".
Heat. On TV Tolstomordinary specialists in agriculture It began to say that wheat burns, and it seems, we are waiting for another cropping. After working, the number of cars on the roads leading to nearby reservoirs makes you remember about Novosibirsk traffic jams. The roadmakers flew on the roads of the crap called "dry asphalt" and, sitting in the tank, are waiting for motorists with their wheels to roll it up to an acceptable state. The number of dismissed glasses does not care. Fir-fermented engine on an attempt to quickly accelerate reacts to long detonation, so it is necessary to press the gas pedal carefully. With low revolutions, the engine also refuses, informing about this ringing knocks. Yes, and idle is not quite even. Preliminary diagnosis - DMRV is poorly working (air flow sensor). The test method was once seen in the journal "driving", but to look for a very long time in paper magazines. Therefore, dive on the Internet. Half an hour and the problem is thoroughly studied, and the method of diagnosis is found. You must first find the yellow wire in the DMRV connector (we are talking about the production sensors of Bosch), usually it is located extreme, and stick to the wire itself or in the connector (along the wire) needle with the calculation so that it touches the metal or contact metal. Then connect one digital tester wire to the needle, the second tester wire is to the mass of the car. Turn on the ignition and see the testimony of the tester. Normal for the sensor are indications from 0.996 to 1.07 V. If the readings do not fall into the specified range, that is, more than 1.07 V or less than 0.996 V, then the sensor at death. But you can try to treat it, after which it is a little more. The main reason for changing the sensor readings is the contamination of the sensitive element having a type of wire or a plate with a layer of platinum layer (so they are so expensive). The design of the inlet path on dozens is such that all microparticles of oil, which supplies the crankcase ventilation system in the intake tract, first settled on the air pipe walls, and then, through the DMRV case, flow into the air filter housing. The more the engine is worn out, the more the oil flows through the DMRV housing and the faster the sensor will be contaminated.
I have a flow of oil well noticeable on the air filter, in the DMRV area, even an oil spot with a radius of 15 mm. The voltage on the sensor was 1.13 V, which was far exceeded by permissible values.
Most. best tool To clean the sensory element of the mass flow sensor, the internet believes an aerosol cleaner of the carburetor. It is believed that if there is a word synthetic word in the title, it cleans it much better. Platinum film on a sensitive element is very thin and fragile, so it is impossible to expose it to any mechanical effects. You can clean only the carburetor cleaner. And in order for the jet to fall on a sensitive element, you need to finalize the sprayer tube a little. For this, the tip of the tube must heat the flame of the lighter and bend at an angle of about 45-75 degrees relative to the axis of the tube. It is most convenient to make it a tweezers. He heard, grabbed tweezers for the tip and bent down. Then the tip must be trimmed in such a way that the hole and the jet of the cleaner splashed at an angle of 45-75 degrees relative to the axis of the tube.
Cleaning technology is easy. It is necessary to remove the sensor from the housing. To do this, unscrew two screws with a TORKS type and gently shaking the sensor to remove it from the housing. The sensor in the housing is compacted by a rubber ring, which is quite firmly held. In the square hole of the sensor (in the photo it is drawn down) we see the plate of the sensitive element. Here we have to rinse it. We enter the sprayer tube into the hole closer to the plate and rinse the jet of the cleaner. Then let it calmly dry, you can care carefully, and check the result. To do this, the sensor in the housing can not be inserted, but simply connect the connector to it. I have left more than half of the cylinder cleaner, until the voltage decreased to 1.07 V. Further flushing of the reduction in the voltage did not give, but the result is normal and it had to stop. The air duct was washed before installing the sensor and the DMRV body from the oil.
The result of the washing of the sensor did not slow down to affect - the detonation disappeared completely. Now you can accelerate how many gas pedal allows. The engine runs smoother, idle dies are disappeared. And, most interesting, vibration disappeared at the Trogan. Before that, I sinned on the clutch - they say, most likely the slave disk curve. In fact, it turned out that flushing DMRV simultaneously straightens the slave clutch disc and the car starts without vibration.
Mass flow sensor. At the bottom of the snapshot is visible to the DMRV connector with the needle inserted.
Cleaner carburetor with a modified tube.
The mass flow sensor (short DMRV) shows how the amount of air is filled in the cylinders when the engine works. DMRV is connected to the wiring system of the wire control 6-pin pad and is in space between the air filter and throttle valve. It is needed to measure which load goes to the engine, and in order for the fuel to be in the desired quantity (for the surveillance for this process, it is just necessary to determine the mass of the air received).
The DMRV is a wire (nitium) and a film type, a fundamental difference is that a platinum wire will be a platinum wire, and a film is a film on which the film resistor is filled with a film. Regardless of the type, DMRV has a pollutant property (platinum elements are covered with dust and work faulty). How to clean DMRV will understand in order.
The main cause of DMRV contamination is the condition of the air filter! If it is bad, it begins to skip the dirt and dust batter with the flow of air, which are settled on the sensitive sensor element.
DMRV cleaning is required if:
- At idle, the engine works with interruptions,
- The cost of idle is unrealistic
- When overclocking "Tupit" (twitching or works intermittent),
- Benz is spent in large quantities
- You can not start in principle.
It also happens that the sensitive element itself is fine, but the connection of the sensor with the throttle module of the junk (the connecting hose can crack). And this is a completely different story. Also, the controller can issuecheck. engineWhat can talk about the same breakage in the sensor connections circuit (and may indicate completely on the other breakdown).
Each owner of the Russian car understands that, despite the obvious signs of a particular part of the machine, these signs may relate to any other malfunction. For this, trust the signs, but check the specifics.
- We take a multimeter, put a voltmeter mode;
- We put the measurement limit - 2 V;
- In the sensor connector, there is a yellow wire (the signal is fed to the controller) and the green wire (the signal is massive);
- We measure the voltage between these wires: Ignition turn on, but I do not start the engine!
- Smori, which showed the multimeter.
Massed from 0.99 to 0.02 - well, the sensor is in order; If the upper limit is increasing about 0.03 - an old sensor, it is urgent to reanimate to a normal state of cleaning. And if the arrow falls behind the lower limit (0.95), or sharply exceeds the upper (0.05) - chances of 50/50, that the flushing of DMRV will help, and it will work as new, or go on shopping for a new sensor.
By the way, there is another way to check the working condition of the mass flow sensor in the fourteenth: disconnect the sensor and start the engine, sneakers to the floor up to 2000 revolutions, trig. Rocked and realized that the car "came to life" - the sensor should be cleaned.
Cleaning DMRV VAZ 2114
Buying a new sensor (air unit) - the pleasure is not cheap. Before running to the nearest store, make sure that your sensor will not help anything.
And help him can correct care. Because, the wrong arms attached to this fragile element can finally destroy it. First, you need to understand how to clean the mass flow sensor and what to clean it.
It has already been said that the dirt is assembled on a sensitive sensor element: that is, on platinum wire or platinum resistor (this is a system of very thin platinum fibers on the film type of air unit). Sensitive elements are very tender, do not think to clean them with the following means:
- Ether-containing liquids
- Ketone-based fluids
- Liquid with acetone
- Cleaner carburetor
- Compressed air and matches with wound!
For a sensor of any vase, including the fourteenth, exists special fluid For flushing DMRV - WD-40.
Process in step-by-step accessibility
Purchase the desired fluid, take a disposable syringe and a flat screwdriver. Even if you are a pro, and know every crack of your car - still read the instructions again, how to clean the air consumption sensor on the VAZ 2114. If you have discovered your fourteenth hood for the first time and you are neat - pray that everything goes smoothly, Parallel reading the instruction.
- Opened the hood, they found the sensor, removed (loosen the fastening of the air filter hose with the sensor, the end key-tenth unscrew the two nuts and vua, ready);
- On the sensor, there is a part announcing his body with two bolts, it must be unscrewed;
- Inside splashing out of the syringe to the sensitive element with the necessary liquid (you can also wash the block of the pads of the pad);
- Let dry.
It remains to collect everything in place and start the engine.
Flushing may not help the first time, after this, do not upset and repeat the process. If it still did not help - you have to buy a new air air.
