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).
Note: The work is shown on an 8-valve engine as an example. On a 16-valve engine, the work is performed similarly.
Removal
1. Prepare the car for work (see "Preparing the car for maintenance and repair").
2. Press the lock to disconnect the wiring harness connector from the sensor.
3. With a socket wrench by 13 mm we unscrew the bolt securing the sensor to the cylinder block.
4. Remove the sensor together with the mounting bolt. Remove the bolt from the sensor.
Examination
1. Connect the multimeter to the sensor terminals (in voltmeter mode with a measurement limit of up to 200 mV).
2. With a metal object (with a bolt, screwdriver) lightly tap the sensor, and the voltmeter should show voltage surges. A faulty sensor does not respond to impacts. In this case, replace it.
Note: The sensor can be tested more accurately only on a special stand.
Installation
We install the sensor in the reverse order.
