Crankshaft Position (CKP) Sensor

CKP sensor is mounted in side of engine block, and is positioned approximately 0.02-0.05" (0.4-1.3 mm) from 60 tooth sprocket mounted on crankshaft. CKP sensor position is not adjustable. Sensor generates a voltage signal to ECM. Two teeth are missing after 58th tooth on sprocket, giving ECM a reference point to determine crankshaft position of 117 degrees before top dead center. Information form CKP sensor allows ECM to ground the fuel pump relay, and is also used to control ignition, fuel injection and knock detection.
