Warning: Before performing repair work to replace the crankshaft position sensor (CPS) on a VAZ 2110 vehicle, read the precautions for repairing the engine management system (see "Precautions when repairing the engine management system").
To perform the work on checking the crankshaft position sensor, you will need: a multimeter (in voltmeter mode).
Removal
1. We are preparing the vehicle for repair work (see points 1 and 2 "Preparing a car for maintenance and repair").
2. Having released the retainer, we disconnect the wire connector from the crankshaft position sensor - in the photo the view from the bottom of the car.
3. Using a 10 mm socket wrench, unscrew the crankshaft position sensor mounting bolt.
4. Remove the crankshaft sensor.
Examination
1. Connect a multimeter to the terminals of the crankshaft position sensor (in voltmeter mode with a measurement limit of up to 200 mV).
2. Quickly move the blade of the screwdriver near the end of the crankshaft position sensor, while observing voltage surges on the voltmeter.
Note. The crankshaft position sensor can be checked more accurately by taking readings from it when it is installed on the engine and the crankshaft pulley is rotating. A working sensor has a voltage of 0.3 V at the terminals. A faulty crankshaft position sensor (CPS) is replaced with a new one.
Installation
We install all the removed parts on the car in the reverse order of removal. Using a set of feeler gauges, we check the gap between the end of the crankshaft position sensor and the teeth of the crankshaft pulley. The gap should be 1±0.41 mm, it is specified by the design of the CKP sensor and is not adjustable.
Recommendation: If the gap is larger than normal, remove dirt from under the crankshaft position sensor.
