Cam Position Sensor Mount: Service and Repair
CAUTION: Prior to starting this procedure, set cylinder number one to 26 degrees After Top Dead Center (ATDC) of the compression stroke. Then note the position of the camshaft sensor electrical connector. The installation procedure requires that the connector be located in the same position.
Removal
1. Disconnect negative battery cable.
2. Remove camshaft sensor assembly.
3. Remove synchronizer clamp (bolt and washer assembly).
4. Remove synchronizer from front engine cover assembly.
NOTE: The intermediate oil pump driveshaft should be removed with the synchronizer assembly.
Installation
CAUTION: If the replacement synchronizer does not contain a plastic locator cover tool, a special service tool such as Syncro Positioner T89P-12200-A or equivalent must be obtained prior to installation of the replacement synchronizer. Failure to follow this procedure will result in improper synchronizer alignment. This will result in the ignition system and fuel system being out of time with the engine, possibly causing engine damage.
1. If the plastic locator cover tool is not attached to the replacement synchronizer assembly, attach Syncro Positioner Tool T89P-12200-A or equivalent as follows:
a. Engage synchronizer vane into the radial slot of the tool.
b. Rotate tool on synchronizer base until tool boss engages the base notch. The cover tool should be square and in contact with entire top surface of synchronizer base.
2. Transfer intermediate oil pump driveshaft from old synchronizer to replacement synchronizer assembly.
3. Install synchronizer assembly so that gear engagement occurs when arrow on locator tool is pointed approximately 30 degrees counterclockwise from the front face of the engine block. This step will locate camshaft sensor electrical connector in the pre-removal position.
4. Install synchronizer base clamp (washer and bolt) and tighten bolt to 20-30 Nm (15-22 lb-ft).
5 Remove Syncro Positioner Tool T89P-12200-A or equivalent.
6. Install and connect camshaft sensor.
CAUTION: If camshaft sensor electrical connector is not positioned properly (i.e. contacting the A/C bracket or forward of the supercharger drive belt), DO NOT reposition the connector by rotating the synchronizer base. This will result in the ignition system and fuel system being out of time with the engine, possibly causing engine damage. Remove the synchronizer and repeat installation procedure, beginning with Step 1.
7. Connect negative battery cable.
