Camshaft Position Sensor

Camshaft Position (CMP) sensor is located on top of cylinder head in camshaft housing. CMP sensor is used to determine crankshaft-to-camshaft position so that PCM can determine which cylinder is ready to be fueled by injector. Sensor is also used to determine which cylinder is misfiring when misfire is present. A problem in the circuit will set a related diagnostic trouble code.
