Crankshaft Position Sensor Replacement 24X CKP Sensor

1. Turn OFF the ignition.
2. Remove the serpentine drive belt from crankshaft pulley.
3. Raise the vehicle on hoist.
4. Remove RH splash shield.
5. Remove the crankshaft harmonic balancer retaining bolt.
6. Remove the crankshaft harmonic balancer using special tool (J 24420-B).
7. Note the routing of sensor harness before removal.
8. Remove the harness retaining clip with bolt (1).
9. Remove the sensor electrical connector.
10. Remove the sensor bolts (2).
11. Remove the sensor.

1. Install the 24X Crankshaft Position Sensor with bolts (2) and route harness as noted during removal.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
