Camshaft Position Sensor Replacement 5.0L, 5.7L

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable.



2. Disconnect the spark plug wires and ignition coil wire from the distributor.



3. Disconnect the CMP sensor harness connector from the distributor.



4. Remove the distributor cap screws.



5. Remove the distributor cap.



6. Remove the rotor screws.



7. Remove the rotor.



8. Remove the CMP sensor screws.



9. Align the square slot in the reluctor wheel with the CMP sensor.



10. Remove the CMP sensor.

Important: Do not use the old cap screws, CMP sensor screws, or rotor screws. Use replacement screws that have been coated with a thread locking compound. Precoated replacement cap and CMP sensor screws can be acquired using P/N 10475922 (pkg of 10 screws). Precoated replacement rotor screws can be acquired using P/N 10475924 (pkg of 10 screws).

1. Align the square slot in the reluctor wheel with the CMP sensor.
2. Insert the CMP sensor through the reluctor wheel slot.




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.

3. Install new CMP sensor mounting screws.

Tighten
Tighten the fasteners to 1.6-2.8 N·m (14-25 lb in).





Important: The locating tabs on the rotor are necessary for correct alignment of the rotor. If the tabs are missing or damaged, replace the rotor.

4. Install the rotor onto the reluctor wheel.



5. Install new rotor fasteners.

Tighten
Tighten the screws to 1.5-2.4 N·m (13-22 lb in)




6. Install the distributor cap.



7. Install new distributor cap screws.

Tighten
Tighten the screws to 1.8-3.0 N·m (16-26 lb in)




8. Connect the CMP sensor harness connector.
