Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Sensor, Camshaft Position: Installation
The magnetic timing wheels (1) must not come in contact with magnets (pickup tools, trays, etc.) or any other strong magnetic field. This will destroy the timing wheels ability to correctly relay camshaft position to the camshaft position sensor.
- Clean out the camshaft position (CMP) sensor mounting bolt hole (2) in cylinder head.
- The CMP sensor seal (1) can be reused if not damaged.
- If required, install a new CMP sensor seal (2) in the cylinder head cover:
- Lubricate the CMP sensor seal inner and outer diameters with clean engine oil.
- Place the CMP sensor seal (2) on the Cam Sensor/Spark Plug Tube Seal Installer (special tool #10256, Installer, Cam Installer, Cam Sensor/ Spark Plug Tube Seal) (1).
- Push the seal into the cylinder head cover until the base of the seal is seated.
- Remove the tool.
NOTE:A properly installed CMP sensor seal (1) will have a 1.5 - 2.0 mm (0.06 - 0.08 in.) gap (2) between the cylinder head cover and the seal upper flange.
- The sensor mounting bolt O-ring (1) can be reused if not damaged.
- Apply a small amount of engine oil to the sensor mounting bolt O-ring (1).NOTE:
The RH CMP sensor is shown in illustration, the LH CMP sensor is similar. If both RH and LH CMP sensors where removed, install them into their original locations.
- Install the CMP sensor to the cylinder head. Tighten the mounting bolt (2) to the proper torque specification. Refer to TECHNICAL SPECIFICATIONS .
- Connect the electrical connector (1) to the sensor.
- Following installation of the LH CMP sensor, install the upper intake manifold (1). Refer to MANIFOLD, INTAKE, INSTALLATION .
- Install the air cleaner body. Refer to BODY, AIR CLEANER, INSTALLATION .
- Connect the negative battery cable.
The Cam/Crank Variation Relearn procedure must be performed using the scan tool anytime there has been a repair/replacement made to a powertrain system, for example: flywheel, valvetrain, camshaft and/or crankshaft sensors or components.
