Crankshaft Position (CKP) Sensor

CKP sensor is located below cylinder No. 7 on the left side of flywheel housing. CKP sensor uses different thicknesses of mounting 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 to 5000-5500 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 and/or the tachometer fails to operate. If CKP sensor is installed incorrectly engine will misfire, run rough or stall. A fault is indicated by illumination of the MIL. If CKP sensor input signal wire and ground wire are inadvertently reversed, the ECM will advance ignition timing 3 degrees.
