Granta mass air flow sensor: granta car mass air flow sensor

Design

Structurally, the sensor is made of plastic and is similar to a pipe. Inside the sensor there is a special sensitive element, which actually counts the air that passes through it. The sensing element is securely fixed in the sensor. A special mesh is installed in front of this part, which protects it from damage.

The sensor is attached with two 6 mm bolts to the air filter housing through a special o-ring, and on the other side through a clamp to the corrugation of the intake manifold.

Is it possible to connect this DMRV through an additional resistance?

Can you tell me where I bought this MAF sensor (118th). I'm covered. I can’t find it either in the city or on the Internet. If I don’t find it, I don’t know what to do. At least transfer to a trampler.

Are you sure you have 118? They look the same, but may differ in markings.

It's in my garage

I flushed with ABRO CARB. Before this the engine stalled.

It’s strange, you have a Granta automatic transmission of 16 class, and the DMRV is marked for 8 class. It should be?

If I'm not mistaken they are no different for 8 or 16 valve engines

Thank you, the salesman in the auto store said the same thing) the only thing was that I wanted to install the Boshevsky one, but the connector turned out to be different.

For what reason do you want to change the mass air flow sensor?

Have already changed! The car was stalling and stalling in the heat with the air conditioner on. I measured it with a multimeter and it was 1.7)

1.7 is this the readings of the mass air flow sensor multimeter?

Maybe it is so)) The new MAF showed 1.01 in the multimeter. I read the information on the measurements here: www.drive2.ru/l/2893171/

I will say this, after the procedure for replacing the DMRV, the car came to life, the idle speed became smooth!

on Grant and Kalina 2 one mass air flow sensor is installed. Itelma. Regardless of the number of engine valves. On Kalina 1 it was installed on 8 valve electric gas. Priorovsky Bosch was installed on the 16 valve.

How long to keep the mass air flow sensor

The cost of this sensor is very expensive, and its failure will significantly affect your pocket. To avoid costs for this sensor, you must carefully monitor its condition.

• The risk of mechanical damage to the sensor must be minimized. For any repair work under the hood, it is recommended to remove the mass air flow sensor and put it aside;
• Change air filters in a timely manner, as they can significantly extend the service life of the mass air flow sensor. If the filter is dirty, then all the dust from it will settle on the sensor, thereby gradually disabling it;
• It is not recommended to clean the sensor with various untested liquids, as they can seriously damage it;

By following these small tips you can extend the life of the sensor by ten years.

Possible sensor malfunctions

In Lada Granta and Kalina cars, the mass air flow sensor located in the engine compartment usually fails due to wear and tear if the controller’s service life comes to an end.

In the event of a malfunction, the car owner will encounter the following symptoms:

• The Check Engine indicator appears on the dashboard and does not go out after starting the engine;
• if the device malfunctions, fuel consumption will increase;
• the power of the power unit as a whole will decrease;
• the dynamics of the car will also be disrupted, and when you press the gas pedal, the driver will notice that the car has difficulty picking up speed;
• the driver may also encounter the problem of being unable to start the engine, or starting the engine will be very difficult;
• when idling, the engine speed will fluctuate (the author of the video is the IZO channel)))LENTA).

Checking the mass air flow sensor

The Lada Grant is equipped with a frequency mass air flow sensor. This part is the most reliable and durable compared to its predecessors, but a significant disadvantage is that it is impossible to check it with a conventional multimeter.

To check the frequency sensor, you must use vehicle diagnostics. Therefore, the verification can be divided into three stages; let’s consider each of them in more detail.

Visual inspection

This check is carried out after dismantling the mass air flow sensor, as well as at the time of its removal. During a visual inspection, it is necessary to evaluate the external condition of the sensor; there should be no chips, cracks or nicks on it, the connector must be securely fixed in its groove and not fall out, the sensitive element inside the sensor must be clean, without traces of dust and oil.

If any of the listed defects are present on the mass air flow sensor, they must be eliminated or the sensor replaced.

Substitution check

One of the most accessible and reliable sensor tests. It consists of replacing the sensor from another working car to a faulty one or vice versa. If a car with a sensor from a working car operates normally, most likely the problems with the car were caused by the mass air flow sensor.

Diagnostics

The most useful and reliable option for checking any of the sensors in the car. Checking the mass air flow sensor using diagnostics consists of comparing the ADC channels and, based on the readings obtained, a conclusion is drawn about the operability of the sensor.

Since this check is very expensive and reaches about 2000 rubles, you can use the Chinese ELM 327 scanner and carry out the check yourself using a smartphone. You can read how to do this in our article, here.

Where to buy car accessories

Spare parts and other products for the car are easily available for purchase at auto stores in your city. But there is another option that has recently received significant improvements. You no longer need to wait a long time for a parcel from China: the AliExpress online store now offers the opportunity to ship from transshipment warehouses located in various countries. For example, when ordering, you can specify the “Delivery from the Russian Federation” option.

Replacement

Replacing the sensor is quite simple; you just need to prepare a 10 mm wrench and a Phillips screwdriver and you can start replacing.

• Remove the connector from the sensor;

• Unscrew the corrugation clamp from the sensor;

• Unscrew the two bolts securing the sensor to the air filter housing;

• We remove the sensor and install a new one in its place, not forgetting to install the rubber O-ring.

Troubleshooting methods

There are several options for troubleshooting the device:

1. Replacing the sensor. The surest way to ensure normal system operation is to install a known working controller.
2. Check the connection of the regulator, as well as the functionality of the electrical circuit. It is very rare, but it happens that the regulator refuses to work normally due to oxidation of the contacts on the connector. In this case, you can try to disconnect the sensor and clean the contacts with an iron brush.
3. Rinse the device. This option for restoring performance is considered one of the most popular among our compatriots today. Cleaning usually takes a little time, but you have every chance of restoring the functionality of the regulator. Our resource has already written about flushing the device; detailed step-by-step instructions are presented in this article.
