Warning. Before performing repair work to replace the crankshaft position sensor (DPKV) on a VAZ 2110 car, read the precautions for repairing the engine management system (see "Precautions when repairing the engine management system").
To perform work on checking the crankshaft position sensor, you will need: a multimeter (in voltmeter mode).
Removing
1. We prepare the car for repair work (see points 1 and 2 "Preparing the car for maintenance and repair").
2. Having released the latch, disconnect the wire connector from the crankshaft position sensor - in the photo is a view from the bottom of the car.
3. Using a 10 mm socket wrench, unscrew the bolt securing the crankshaft position sensor.
4. Remove the crankshaft sensor.
Examination
1. We connect a multimeter to the terminals of the crankshaft position sensor (in voltmeter mode with a measurement limit of up to 200 mV).
2. We quickly carry the screwdriver blade near the end of the DPKV sensor, while observing voltage surges on the voltmeter.
Note. More precisely, the crankshaft position sensor can be checked by taking readings from it when it is installed on the engine and the crankshaft pulley rotates. For a working sensor, the voltage at the terminals reaches 0.3 V. Faulty crankshaft position sensor (DPKV) we replace with a new one.
Installation
We install on the car all the removed parts in the reverse order of removahp a set of feelers, we check the gap between the end face of the crankshaft position sensor and the teeth of the crankshaft pulley. The gap should be 1±0.41 mm, it is set by the design of the DPKV sensor and is not adjustable.
Recommendation. If the gap is more than normal, remove dirt from under the DPKV sensor.
