Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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.
