Camshaft Position Sensor: Service and Repair

Alldata Editors Note: Ford provides NO procedure to replace the Camshaft Position Sensor without the special tool shown in this article.

CAUTION: Prior to removal of the Camshaft Position (CMP) sensor, set cylinder No. 1 to 0° Top Dead Center (TDC) of compression stroke. Note position of the CMP electrical connector. The installation procedure requires that the connector be located in the same position.

REMOVAL

1. Disconnect battery ground cable.

NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the Powertrain Control Module (PCM) relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.

2. Disconnect fuel charging wiring connector from stator assembly.

3. Remove stator assembly retaining screws and stator assembly from synchronizer assembly.

4. If synchronizer assembly is to be removed from the cylinder block, proceed with Removal Step 5. If synchronizer assembly is not being removed, proceed to Installation Step 6.

5. Remove hold-down clamp (bolt and washer assembly).

6. Remove synchronizer assembly from cylinder block.

NOTE: The oil pump intermediate shaft should be removed with the synchronizer assembly.

INSTALLATION

Camshaft Position Sensor:

CAUTION: If the replacement synchronizer assembly sensor housing does not contain a plastic locator cover tool, a special service tool such as Syncro Positioning Tool T89P-12200-A, one must be obtained prior to installation of the replacement synchronizer assembly. Failure to follow this procedure will result in improper synchronizer assembly alignment. This will result in the 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 Positioning Tool T89P-12200-A as follows:

a. Engage synchronizer assembly vane into the radial slot of the tool.

b. Rotate tool on synchronizer assembly until tool boss engages notch in synchronizer assembly.

2. Transfer oil pump intermediate shaft from old synchronizer assembly to replacement synchronizer assembly.

3. Install synchronizer assembly so that drive gear engagement occurs when arrow on locator tool is pointed approximately 30° counterclockwise from the rear face of the cylinder block. This step will locate camshaft position sensor electrical connector in the pre-removal position.

4. Install hold-down clamp (washer and bolt) and tighten bolt to 20-30 Nm (15-22 lb ft).

5. Remove Syncro Positioning Tool T89P-12200-A.

6. Install CMP sensor and retaining screws. Tighten screws to 2.5-3.5 Nm (22-31 lb in).

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.

7. Connect fuel charging wiring connector to camshaft position sensor stator assembly.

8. Connect battery ground cable.
