Camshaft Position (CMP) Sensor
The camshaft position (CMP) sensor is located in the cylinder head near the number 4 fuel injector. The CMP sensor is a signal generator that is composed of a magnet and a coil with an iron core. The PCM relies on the AC signal provided by the CMP sensor in order perform the following:
- To optimize the ignition timing
- To optimize the fuel delivery
- To detect any engine misfire
- To monitor CMP actuator solenoid valve operation
