Crankshaft Position Sensor: Description and Operation
Crankshaft Position (CKP) Sensor
The crankshaft position (CKP) sensor is located on top of the flywheel housing. There are 56 notches spaced 6° apart and a 24° section that is uncut.
This uncut portion allows for the defection of top dead center (TDC). The CKP sensor is a magnet coil type sensor, which generates an AC signal
voltage based on the crankshaft rotational speed. If the CKP sensor fails, the camshaft position sensor (CMP) sensor signals will substitute for the CKP
sensor signals back up.
