CKP Sensor
The
CKP sensor is located in the engine front cover perpendicular to a reluctor ring mounted on the crankshaft nose. The reluctor ring has 3 or 4 slots depending on whether the engine has 6 or 8 cylinders. As the reluctor rotates past the sensor tip, the slots change the sensor magnetic field to produce a voltage ON-OFF signal. Based on these signals, the PCM is able to determine crankshaft speed and position.
