Camshaft Position Sensor
WARNING: This page is about a different variant/trim than selected.
The CMP s are Hall effect type sensors that allow the PCM to determine the angular position of the camshafts. The CMP s are of the ferro-magnetic resistance element type. The CMP s produce a digital output which allows the PCM to detect speeds down to 0.
The 4 CMP s are located in the front upper timing covers, 1 for each camshaft.
Each CMP is installed with a single screw and sealed with an o-ring. On each CMP , a 3-pin electrical connector provides the interface with the engine wiring harness.
The head of each CMP faces a reluctor ring attached to the front of the related VCT actuator.
- If an exhaust CMP
fails
- The PCM disables the VCT of both exhaust camshafts.
- If an intake CMP
fails.
- The PCM disables the VCT of both intake camshafts.
This can result in reduced engine performance and slow to start. A failed CMP does not prevent the engine starting.
