Crankshaft Position Sensor — Replacement (Opel Zafira A)

The necessity of performing this operation should be determined during the inspection of the technical condition of the engine control system (see "Engine management system - technical condition check and fault diagnostics").

Warning! Before performing the operation, be sure to read the section "Safety precautions for maintenance and repair of the engine management system".

Note: Depending on the engine model and year of the vehicle, the crankshaft position sensors may differ and have different locations. Two options are discussed below.

To complete the job you will need a set of flat feeler gauges.

Replacing the sensor located in the cylinder block

1. Prepare the car for work (see "Preparing the car for maintenance and repair").

2. Disconnect the wiring harness connector from the sensor.



3. Using a 10 mm socket wrench, unscrew the crankshaft position sensor mounting bolt.
