Warning. Read the Precautions for Repairing the Engine Control System Before Performing Repairs (see "Precautions when repairing the engine management system").
To perform repair work on replacing a knock sensor on a VAZ 2110 car, you will need a multimeter (in voltmeter mode).
Note. Access to the DD sensor makes it difficult for the intake module. Therefore, it will have to be removed by touch. You can remove the engine protection and work from below the car (on a viewing hole or overpass).
Removing
1. We prepare the car for work (see points 1 and 2 "Preparing the car for maintenance and repair").
2. Using a 13 mm socket wrench, unscrew the bolt securing the knock sensor to the cylinder block.
3. Remove the sensor from under the intake module.
4. Pressing the latch, disconnect the wiring harness connector from the sensor.
Examination
1. Connect a multimeter to the sensor terminals (in voltmeter mode with a measurement limit of up to 200 mV).
2. Metal object (bolt, screwdriver) lightly tap on the sensor, while voltage surges should be observed on the voltmeter. A faulty knock sensor does not respond to impacts. In this case, the knock sensor must be replaced.
Note. More accurately, the sensor can only be checked on a special stand.
Installation
We install on the car all the removed parts in the reverse order of removal.
