Crankshaft Position (CKP) Sensor

CKP sensor utilizes a 4-wire dual Hall Effect switch mounted near vibration damper. Sensor monitors vibration damper position (crankshaft position) and sends signals to ignition control module, which passes these signals on to the PCM. These signals provide PCM with a TDC position reference for each piston, as well as supplying an engine speed (RPM) signal.
