What is an air sensor?
VAZ-2110 and many other models of the "tenth family" have a similar design of DMRV. Basically, this spare part is a small device that is installed in the nozzle and connects the throttle valve to the air filter (hence the name - the air sensor). Its main function is to control the volume of air that enters the injector motor.
How can I determine if this part is malfunctioning?
The main symptom of a mass air flow sensor failure is uneven engine operation. At its work the driver feels sharp jumps of turns, wrong dynamics of dispersal and faults at idling. Also, when this part is broken, it's very difficult to start a car: even if on the street plus 30, in the salon the heat and the engine are hot, it's unlikely that you will be able to go somewhere with such a car.
Can it be repaired?
Unfortunately, this part can not be repaired. In case of breakage, it can only be replaced. In addition, the VFD-2110 DMRV is a very vulnerable device: it can be broken even when its surface is often cleaned (especially often when the device is cleaned with cotton).
Precisely, after how many it is necessary to replace the mass air flow sensor, it is impossible - it can break even after 10 thousand kilometers, and can serve 100 thousand or more. Everything depends on the specific operating conditions and on the quality of the assembly of the part itself.
Sensor DFID VAZ-2110: price
On average, the cost of a new spare part for the "tens" is about two thousand rubles. But in the stores you can see the details with much less value. As a rule, these are sensors without a housing. But to buy them for the sake of economy is not worth it, since such a spare part can soon break down. It is also possible that such a mass air flow sensor simply does not work for your iron friend.
