Crankshaft Position (CKP) sensor – replacement
1. Disconnect the cable (s) from the negative battery terminal(s) (see Engine electrical systems).
5.3a Disconnect the CKP sensor electrical connector (A) and remove the sensor mounting bolt (B) (3.7L V6 engine)
5.3b Disconnect the CKP sensor (A) electrical connector (B) and remove the sensor mounting bolt (C) (4.7L V8 engine)
5.3c Disconnect the CKP sensor (A) electrical connector (B) and remove the sensor mounting bolt (C) (Hemi engine, right-rear side shown)
2. Raise the front of the vehicle and support it securely on jackstands.
Gasoline engines
Note: The CKP sensor is located on the right rear side of the engine block.
3. Disconnect the electrical connector from the CKP sensor (see illustrations).
4. Remove the CKP sensor mounting bolt. Remove the sensor from the engine.
5. Remove the CKP sensor 0-ring and inspect it for cracks, tears and deterioration. If it’s damaged, replace it.
6. Apply a small amount of engine oil on the 0-ring and, using a slight rocking motion, push the sensor into its mounting hole in the engine block until the sensor is fully seated.
7. Installation is otherwise the reverse of removal.
Diesel engine
Note: The CKP sensor is located on the front left side of the engine, next to the harmonic balancer.
8. Disconnect the electrical connector from the CKP sensor (see illustration).
5.8 Disconnect the CKP sensor electrical connector and remove the sensor mounting bolt (diesel engine)
9. Remove the CKP sensor mounting bolt and remove the CKP sensor.
10. Remove and inspect the old sensor 0-ring. If it’s cracked, torn or deteriorated, replace it.
11. Before installing the CKP sensor, clean out the sensor’s mounting hole and apply a little clean engine oil to the sensor 0-ring.
12. Install the CKP sensor using a slight rocking motion. Make sure that the sensor is flush with its mounting surface before installing and tightening the sensor mounting bolt.
13. Installation is otherwise the reverse of removal.
