Replacing the DMRV on the Grant with your own hands
The mass air flow sensor on Lada Grant cars can properly serve the entire period of its operation, up to a mileage of 300 km. This is not a theory, but the personal experience of many owners who drove on such engines (000 1,6-cl) just such a mileage without a single DMRV replacement.
The main reason why this air sensor fails is the fault of the owners themselves. Why is this happening? The answer is simple - untimely replacement of the air filter leads to failure of the DMRV. So it is better to change the filter as often as possible, and it is quite enough to do this at least once every 10 km, because it costs a penny, and the price of the sensor is 000 times more expensive and can reach 20 rubles, depending on the manufacturer.
If you are still unlucky and this part needs to be replaced, then this repair is performed quite simply, for this you just need:
- crosshead screwdriver
- 10 socket head
- Crank or ratchet
The order of performing this work is as follows. First you need to disconnect the power harness connector from the mass air flow sensor. Grants:
After that, we loosen the clamp bolt on the inlet pipe that connects the sensor to the throttle:
And then we take the branch pipe to the side so that it does not interfere with further work:
Now you just need to unscrew the two bolts with which the DMRV is attached to the air filter housing:
And remove the sensor, since there are no more fasteners and it can be freely removed without unnecessary effort:
Now it remains to buy a new mass air flow sensor, which will not cost you so cheaply, and replace it. Installation is carried out in reverse order.
