Caution: Prior to the removal of the camshaft position sensor, set No.1 cylinder to 0 degrees top dead center (TDC) of compression stroke. Then note the position of the camshaft position sensor electrical connector The installation procedure requires that the connector be located in the same position.
Disconnect battery ground cable.
Disconnect fuel charging wiring connector from stator assembly.
Remove the CMP sensor retaining screws and camshaft position sensor from synchronizer assembly.
If synchronizer assembly is to be removed from the cylinder block, proceed with Step 5. If the synchronizer assembly is not being removed, proceed to installation Step 6.
Remove hold-down clamp.
Remove synchronizer assembly from cylinder block.
If the replacement synchronizer assembly housing does not contain a plastic locator cover tool, SST must be obtained prior to 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.
Do not move crankshaft until entire assembly procedure is complete. Doing so will result in the fuel system being out of time with the engine resulting in possible engine damage.
Align the synchronizer vane with the radial slot of the SST.
Rotate the SST on the synchronizer base until the SST's boss engages the base notch.
Dip gear end into engine oil to coat gear, thrust washer and lower bearing.
Insert the synchronizer assembly (with SST ) into the block. The SST should be aimed approximately 75 degrees counterclockwise from the centerline of the engine.
Rotate the SST clockwise slightly to engage the oil pump intermediate shaft. Continue the downward motion, twisting the SST lightly until the synchronizer gear engages the camshaft gear.
With the synchronizer flange fully seated against the block, the SST should point rearward 33 to 45 degrees counterclockwise off engine centerline.
Install hold-down clamp.
Tightening torque: 18-29 N-m (13-21 lb-ft)
Caution: If camshaft position sensor electrical connector is not positioned properly, DO NOT reposition the connector by rotating the synchronizer assembly. This will result in the fuel system being out of time with the engine, possibly causing engine damage. Remove the synchronizer assembly and repeat installation procedure, beginning with Step 1.
Install CMP sensor and retaining screws.
Tightening torque: 1.5-4.0 N-m (14-35 lb-in)
Connect connector to camshaft position sensor stator assembly.
Connect battery ground cable.
Note: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.
