Crankshaft Position (CKP) Sensor

CKP sensor is located on the left side of flywheel housing and uses different thicknesses of spacers for manual and automatic transmissions. CKP sensor provides ECM with information indicating that engine is turning, engine speed and crankshaft position. ECM controls fuel injection and coil firing based on signal from CKP sensor. Engine overspeed protection is set at 5500 RPM and is based on CKP sensor signal. There is no default strategy for the CKP sensor. A failure will result in an engine no start condition. A fault is indicated by illumination of the MIL.

CKP sensor output signal is obtained from the magnetic path being made and broken as the reluctor ring teeth pass CKP sensor tip. Reluctor ring has 35 teeth and one missing tooth spaced at 10 degree intervals. The missing tooth is positioned at 20 degrees after TDC.
