Crankshaft Position Sensor Replacement 7X CKP Sensor
Removal Procedure
- Turn OFF the ignition
switch.
- Crank steering wheel fully to the left.
- Raise the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Disconnect the sensor electrical connector.
- Remove the attaching bolt/screw.
- Remove the sensor from engine.
- Inspect for wear, cracks, or leakage if the sensor is not being
replaced.
Installation Procedure
- Lubricate the O-ring with clean engine oil before installation
and replace if damaged.
- Install the sensor to
the block.
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.
- Reinstall the
sensor attaching bolt.
Tighten
Tighten the bolt to 8 N·m (71 lb in).
- Connect the sensor electrical connector.
- Lower the vehicle.
