Crankshaft Position Sensor: Description and Operation
Crankshaft Position (CKP) Sensor
Crankshaft Position (CKP) Sensor
The Crankshaft Position (CKP) sensor (1) is mounted in the engine block (2), behind the flywheel or flexplate. The PCM receives a digital signal from
the CKP sensor. The PCM uses the CKP sensor signal in order to determine crankshaft speed. The PCM uses crankshaft speed as one of the inputs in
engine misfire monitoring. The CKP sensor is not adjustable.
Camshaft Position (CMP) Sensor
Operation
The CKP sensor (4) generates a magnetic field within the magnet (3) and coil (2) assembly. The CKP sensor has a specified air gap between the
sensor core end and the crankshaft signal rotor (1) that is located on the crankshaft. An AC voltage is generated in the sensor when crankshaft rotation
causes a change in the magnetic flux. The CKP sensor sends the A/C voltage signal to the PCM.
