Circuit Description

The Camshaft Position (CMP) sensor signal, when combined with the CKP sensor signal, enables the PCM to determine exactly which cylinder is on a firing stroke. PCM can then properly synchronize the ignition system, fuel injectors and knock control. PCM supplies 12 volts to sensor. Power and reference low circuits are also connected to CKP sensor. DTC will set when PCM detects a problem with the CMP sensor signal.
