Camshaft Position Sensor

Camshaft Position Sensor

Special tools, testers and auxiliary items required

• Cam Sensor/Spark Plug Tube Seal Installer (10256)

Removing







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.







The Camshaft Position (CMP) sensors are located at the rear of the cylinder head covers and are bolted to the cylinder head.

- Disconnect the negative battery.

- Remove the air cleaner housing. Refer to => [ Air Cleaner Housing ] Air Cleaner Housing.

- If removing the LH CMP sensor, first remove the upper intake manifold (2). Refer to => [ Upper Intake Manifold ] Upper Intake Manifold.







• The RH CMP sensor is shown, the LH CMP sensor is similar. If removing both RH and LH CMP sensors, mark the sensors so they can be installed in their original locations.

- Disconnect the electrical connector (1) from the CMP sensor.

- Loosen the sensor mounting bolt (2).







- Pull the sensor and mounting bolt from the cylinder head cover.

- The O-ring seal (1) can be reused if not damaged.

Installing







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 (10256) (1).

• Push the seal into the cylinder head cover until the base of the seal is seated.

• Remove the tool.







• 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).







• The RH CMP sensor is shown, 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 9 Nm (80 in. lbs.).

- Connect the electrical connector (1) to the sensor.







- Following installation of the LH CMP sensor, install the upper intake manifold (1). Refer to => [ Upper Intake Manifold ] Upper Intake Manifold.

- Install the air cleaner housing. Refer to => [ Air Cleaner Housing ] Air Cleaner Housing.

- 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.
