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. Using a 10 mm socket wrench, 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 hung more accurately if readings are taken from it when it is installed on the engine and the crankshaft pulley is rotating. A working sensor has a voltage at the terminals of 0.3 V. We replace the faulty sensor.
Installation
We install the crankshaft position sensor in the reverse order of removal. Using a set of feeler gauges, we check the gap between the sensor tip and the teeth of the crankshaft pulley. The gap should be 1±0.41 mm, it is specified by the sensor design and is not adjustable.
Advice: If the gap is larger than normal, remove dirt from under the sensor.
