Camshaft Position Sensor: Description and Operation
Cam Position Sensor
The Camshaft Position (CMP) Sensor is located in the distributor and consists of the signal generator (pickup coil and magnet) and signal rotor.
As the signal rotor turns, pulsing AC voltage is generated in the pick-up coil. This pulse signal (4 pulses per revolution) is sent to the PCM where it is
used to calculate the engine speed, and as one of the signals to control various devices.
