Camshaft Position Sensor: Service and Repair

CAUTION: DO NOT TURN THE CAMSHAFT DURING THE REMOVAL AND INSTALLATION PROCEDURE OR THE FUEL SYSTEM TIMING WILL BE OUT OF TIME WITH THE ENGINE AND POSSIBLY CAUSE ENGINE DAMAGE.

NOTE: Prior to the removal of the Camshaft Position (CMP) sensor, set the No.1 cylinder to Top Dead Center (TDC) of the compression stroke. Then note the position of the CMP sensor electrical connector. Installation procedures require that the electrical connector be located in the same position.

REMOVAL

CAUTION: DO NOT TURN THE CAMSHAFT DURING THE REMOVAL AND INSTALLATION PROCEDURE OR THE FUEL SYSTEM TIMING WILL BE OUT OF TIME WITH THE ENGINE AND POSSIBLY CAUSE ENGINE DAMAGE.

NOTE: Prior to the removal of the Camshaft Position (CMP) sensor, set the No.1 cylinder to Top Dead Center (TDC) of the compression stroke. Then note the position of the CMP sensor electrical connector. Installation procedures require that the electrical connector be located in the same position.

1. Disconnect the Camshaft Position (CMP) sensor electrical connector.






2. Remove the camshaft synchronizer bolt.






3. Remove the camshaft synchronizer.

NOTE: The oil pump driveshaft might come out with the camshaft synchronizer. If so, retrieve the oil pump drive shaft before proceeding.

INSTALLATION

CAUTION:
^ A special tool must be used during the installation of the replacement synchronizer assembly. Failure to follow this procedure will result in the fuel system being out of time with the engine, possibly causing engine damage.
^ It is very important to coat the gear on the camshaft synchronizer with Super Premium SAE-5W-30 Motor Oil XO-5W30-DSP or equivalent meeting Ford specification WSS-M2C153-G. Failure to do so could result in gear failure.






1. Install the special tool by rotating the tool until it engages the notch in the camshaft synchronizer housing and the armature.











2. Install the camshaft synchronizer.

NOTE:
^ When installing the camshaft synchronizer into the cylinder block, make sure that the arrow on the special tool is pointing toward the rear of the vehicle.
^ The synchronizer will rotate slightly as the synchronizer gear engages the camshaft gear. When the synchronizer is fully installed the arrow on the special tool should point to the position of the electrical connector.






3. Position the clamp and install the bolt.
4. Remove the special tool.
5. Install the Camshaft Position (CMP) sensor.
6. Install the upper intake manifold.
