Warning! Before performing work, read the precautions for repairing the engine management system (see "Precautions when repairing the engine management system").
To complete the work you will need a multimeter (in voltmeter mode).
Removal
1. Prepare the car for work (see "Preparing the car for maintenance and repair").
2. Having released the retainer, we disconnect the wiring block from the crankshaft position sensor (the photo shows a view from underneath the car).
3. With a socket wrench by 10 mm unscrew the crankshaft position sensor mounting bolt.
4. Remove the sensor.
Examination
1. Connect the multimeter to the sensor terminals (in voltmeter mode with a measurement limit of up to 200 mV).
2. Quickly move the blade of a screwdriver near the end of the sensor, while observing voltage surges on the voltmeter.
Note: The 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 sensor must be replaced.
Installation
We install the crankshaft position sensor in the reverse order. Using a set of feeler gauges, we check the gap between the end of the sensor and the teeth of the crankshaft pulley. The gap should be 1+0.41 mm, it is specified by the design of the sensor and is not adjustable.
Advice: If the gap is larger than normal, remove dirt from under the sensor.
