Crankshaft Position Sensor: Description and Operation

Crankshaft Position Sensor (CKP):

DESCRIPTION
The Crankshaft Position (CKP) sensor consists of a magnet and coil. It is mounted on the oil pan with a specified air gap between the sensor core end and the crankshaft timing belt pulley tooth.

OPERATION
As the crankshaft turns, an AC voltage (pulse) is generated in the sensor. The PCM detects the crankshaft revolution speed from the signal and uses it as one of the signals for misfire monitoring.
