Crankshaft Position (CKP) Sensor

On V8 engines, CKP sensor is located at the rear of the bedplate, near flywheel. On V6 engines, CKP sensor is located on the front cover, near crankshaft pulley. The CKP provides ECM or PCM with information on engine speed and crankshaft position. ECM uses this information to control fuel injection pulse rate and ignition timing. CKP sensor is also used for misfire detection.
