Camshaft Position Sensor

The Camshaft Position (CMP) sensor is a signal generator (pick-up coil and magnet) and a signal rotor. On Metro & Firefly (Canadian) 1.0L, CMP sensor is mounted inside distributor housing. On all others, CMP sensor is mounted in cylinder head. A pulsing signal (one pulse per cylinder) is sent to PCM and is used to identify cylinder, calculate engine speed, determine injector firing and monitor cylinder misfire.
