CAMSHAFT POSITION (CMP) SENSOR


Synchronizer Alignment Gauge:






SPECIAL TOOL(S)

REMOVAL
1. Disconnect the battery ground cable.
2. If removing the camshaft synchronizer, drain the cooling system.

3. CAUTION: Do not turn the crankshaft or the camshaft after the No. 1 cylinder is at top dead center (TDC) of the compression stroke or the fuel system timing will be out of time with the engine and possibly cause engine damage.

Rotate the crankshaft until the No. 1 cylinder is at top dead center (TDC) of the compression stroke.












4. Remove the parts in the order indicated in the illustration and table.

To remove individual parts, only carry out the listed steps.

Item 8: Power Steering Pump Bolts Removal Note
1. The bolt that is positioned under the power steering pressure line fitting will remain with the pump.

Item 11: Camshaft Synchronizer Removal Note
1. The oil pump driveshaft might not come out with the camshaft synchronizer. If so, retrieve the oil pump driveshaft before proceeding.

INSTALLATION
1. To install, reverse the removal procedure.
2. Fill and bleed the cooling system.

Item 11: Camshaft Synchronizer Installation Note







1. CAUTION:
- After installation, do not loosen the synchronizer bolt and rotate the synchronizer assembly. The synchronizer assembly is not adjustable. Do not loosen the synchronizer bolt after the alignment tool has been removed in order to align the CMP electrical connector for any reason. If the electrical connector is not in the correct position, the synchronizer assembly must be removed, the alignment tool and the assembly reinstalled if the engine has not been rotated from top dead center (TDC) of the compression on the No. 1 cylinder.
- A special tool must be used when installing a synchronizer assembly. Failure to follow this procedure will result in the fuel system being out of time with the engine, possibly causing engine damage.


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







2. CAUTION: It is very important to coat the gear on the camshaft synchronizer with clean engine oil prior to installation. Failure to do so could result in gear failure.

NOTE: During installation, the arrow on the special tool will rotate clockwise until the oil pump intermediate shaft and camshaft gear engages.

Install the camshaft synchronizer housing assembly so the arrow on the special tool is 54 degrees from the centerline of the engine.
