Camshaft Position (CMP) Sensor

WARNING: This page is about a different car, the 2017 Jaguar XJ, 2016 Jaguar XJ, 2015 Jaguar XJ, 2014 Jaguar XJ, and 2013 Jaguar XJ. However, it is still accessible from the selected car via links, so may be relevant.

The Camshaft Position (CMP) sensors are magneto resistive element sensors that allow the ECM to determine the angular position of the camshafts. Magneto resistive element sensors produce a digital output which allows the ECM to detect speeds down to zero.

Four CMP sensors are installed in the front upper timing covers, one for each camshaft.

Each CMP sensor is secured with a single screw and sealed with an O-ring. On each CMP sensor, a three pin electrical connector provides the interface with the engine harness.

The head of each CMP sensor faces a sensor wheel attached to the front of the related VCT unit.

If an exhaust CMP sensor fails, the ECM disables the VCT of both exhaust camshafts.

If an intake CMP sensor fails, the ECM disables the VCT of both intake camshafts. This can result in the engine being slow, or failing, to start.
