Removal Procedure
- Disconnect the electrical connector (1) from the camshaft position (CMP) sensor.
- Scribe an alignment mark on the flange of the CMP sensor housing and the cylinder head.
- Remove the CMP sensor housing boltS (3).
- Remove the CMP sensor (2) from the cylinder head.
Installation Procedure
- Install a new O-ring (1) on the CMP sensor housing (2).
- Lubricate the CMP sensor O-ring with engine oil.
- Align the offset coupling (1) of the CMP sensor (2) in order to correctly engage the drive slot in the end of the camshaft.
- Install the CMP sensor housing into the cylinder, while observing the offset coupling on the CMP sensor for proper alignment during installation.
- Install the CMP sensor housing bolts (3), but do not tighten the bolts.
- Rotate the CMP sensor housing (2) until the scribed alignment marks are matched up.
- Tighten the CMP sensor housing bolts.
- Connect the CMP sensor electrical connector (1).
- Install a timing light and check the ignition timing. Refer to Ignition System Timing Adjustment .
Important: Do not use force to install the CMP sensor housing into the cylinder head. The CMP sensor coupling has an offset drive that engages an offset slot in the end of the camshaft. Align the CMP sensor coupling and the camshaft slot before installing the CMP sensor housing into the cylinder head.
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.
Tighten
Tighten the bolts to 15 N·m (11 lb ft).
