Note. The work on removing, checking and replacing the DPRV sensor is shown on a VAZ 2110 car with an injection engine VAZ 21124 (1,6i). Removing and checking the camshaft sensor on a car with a VAZ 2112 engine (1,5i) performed similarly.
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 to replace the sensor, you will need: a multimeter (in voltmeter mode).
Removal and inspection
1. We prepare the car for repair work (see points 1 and 2 "Preparing the car for maintenance and repair").
2. Remove the engine trim (see "Decorative overlay of the engine - removal and installation").
3. Having released the latch, disconnect the wire connector from the camshaft position sensor (DPRV).
Note. For clarity, the photographs were taken from the side of the radiator of the engine cooling system.
4. Connect «negative» voltmeter probe to «mass» (to the car body).
5. Turning on the ignition, use a voltmeter to measure the supply voltage at terminal A of the wiring harness connectors (pin designations are made on the connector).
Note. The voltage at the output must be at least 12 V. If the voltage is not supplied to the connector or it is less than 12 V, then the battery is discharged, the power circuit is faulty or the computer is faulty.
6. Using a 10 mm socket wrench, unscrew the two bolts securing the camshaft position sensor (DPRV).
7. We remove the camshaft position sensor from the hole in the rear cover of the timing belt.
Recommendation. Check if the camshaft position sensor is faulty (DPRV) You can replace it with a known good one.
Installation
We install on the car all the removed parts in the reverse order of removal.
