Tools Required

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. Refer to Battery Cable in Engine Electrical.



2. Remove the serpentine belt(s) from the crankshaft pulley. Refer to Drive Belt Replacement in Engine Mechanical.

Caution: Provide additional support when a vehicle is on a hoist:

•	Before removing parts, support the opposite end. This helps prevent the vehicle from slipping off.

•	Before removing major components, chain the vehicle frame to the hoist pads at the same end as the removal. This helps avoid a tip-off.

Failure to follow these precautions could cause vehicle damage, serious personal injury, or death.
3. Raise the vehicle on a hoist.
4. Remove the right front wheel and tire assembly. Refer to Tire and Wheel Removal and Installation .
5. Remove the right inner fender access cover. Refer to Wheelhouse Panel Replacement .
6. Remove the flywheel inspection cover.
7. Hold the flywheel with J 37096 Flywheel Holding Tool.



8. Using 28 mm socket, remove the crankshaft harmonic balancer retaining bolt.
9. Remove the crankshaft harmonic balancer using special tool J 38197-A Balancer Remover.



10. Disconnect the sensor electrical connector (1).



11. Remove the crankshaft position sensor shield. (Do Not use a pry bar).



12. Remove the 2 attaching bolts from the crankshaft position sensor (3).



13. Remove the crankshaft position sensor from block face.

1. Position the crankshaft position (CKP) sensor to the block.
2. Install the bolts to hold the CKP sensor to the block face.

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.
