Crankshaft Position Sensor: Service and Repair

18.30.12 Sensor - Crankshaft Position (CKP)

Before disconnecting the battery, ensure all text and cautions in the battery disconnection section are observed.

Remove
1. Position vehicle on lift.
2. Disconnect battery earth lead.





3. Raise vehicle and disconnect multiplug from CKP sensor.
4. Clean area surrounding CKP sensor.
5. Remove Allen screw and remove CKP sensor.

Refit
1. Clean casing mating face.





2. Observe the following when replacing the transmission, incremental gear or the CKP sensor. If one or more spacers are fitted between transmission and CKP sensor, the distance between the sensor and teeth on the incremental gear must be measured.
3. Rotate crankshaft until a full 'trigger' tooth is visible through aperture in casing. Ensure the tooth is centered to the hole.
4. Using a depth micrometer, measure depth from sensor mating face to 'trigger' tooth. Record measurement.





5. Measure length of CKP sensor between tip and mounting face, dimension 'A'. Record dimension.
6. Subtract length of CKP sensor, from sensor mating face to 'trigger' tooth dimension and record the resulting gap. The Air gap should be adjusted to 0.55 mm +/- 0.2 (.022 in +/-.0080), using available shims.
7. Fit shim to CKP sensor if required. Align CKP sensor to casing, fit bolt and tighten to 10 Nm (7 lbf.ft).
8. Connect CKP sensor multiplug.
9. Connect battery earth lead.
10. If a replacement sensor has been fitted re-set adaptions using TestBook/T4.
