Q: What is the purpose and location of the Crankshaft Position (CKP) sensor?
A: The Crankshaft Position(CKP) sensor determines the timing for the fuel injection and ignition on each cylinder. The crankshaft sensor is mounted on the timing chain cover next to the crankshaft pulley. A problem in the crankshaft sensor circuit will set a diagnostic trouble code. Loosen the right front wheel lug nuts. Disconnect the cable from the negative battery terminal. Raise the front of the vehicle and support it securely on jack stands. Remove the wheel and the inner fender shield. Remove the two bolts(one secures the sensor, the other is close by and secures the harness) and detach the sensor. At the upper part of the timing chain cover, disconnect the harness connector and remove the harness and sensor. Installation is the reverse of removal. Be sure to use a new O-ring on the sensor, lightly coated with engine oil.
