Crankshaft Position Sensor
WARNING: This page is about a different car, the 2015 Jaguar XK, 2014 Jaguar XK, 2013 Jaguar XK, and 2012 Jaguar XK. However, it is still accessible from the selected car via links, so may be relevant.
The characteristics of the signal supplied by the CKP sensor are learned by the ECM. This enables the ECM to set an adaption and support the engine misfire detection function. Due to the small variation between different drive plates and different CKP sensors, the adaption must be reset if either component is renewed, or removed and refitted. It is also necessary to reset the drive plate adaption if the ECM is renewed or replaced. The ECM supports four drive plate adaptions for the CKP sensor.
Each adaption relates to a specific engine speed range. The engine speed ranges are detailed in the service information below:
| ADAPTION | ENGINE SPEED, REV/MIN |
|---|---|
| 1 | 1800 - 3000 |
| 2 | 3001 - 3800 |
| 3 | 3801 - 4600 |
| 4 | 4601 - 5400 |
