Camshaft Position Sensor: Service and Repair



NOTE: Ford does not provide a TDC (Top Dead Center) mark or determination procedure for this engine in this vehicle.
ALLDATA users have reported success using aftermarket tools to determine TDC on this engine.

REMOVAL
1. Disconnect battery ground cable.

NOTE: When the battery has been disconnected or 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 from camshaft position sensor.
3. Remove retaining screws and camshaft position sensor from housing.
4. If removing camshaft position sensor housing from the engine front cover, proceed with Removal Step 5. If housing is not being removed, proceed to Installation Step 7.
5. Remove retaining bolt and hold-down clamp.

CAUTION: Before proceeding with this procedure, set cylinder No. 1 zero degrees Top Dead Center (TDC) of the 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.

6. Remove camshaft position sensor housing from engine front cover.

NOTE: The oil pump intermediate shaft should be removed with the camshaft position sensor housing.






INSTALLATION
1. Attach Syncro Positioning Tool T96T-12200-A on camshaft position sensor housing and turn it clockwise until tool boss engages notch in camshaft position sensor housing.

CAUTION: Special service tool Syncro Positioning Tool T96T-12200-A must be obtained prior to installation of the camshaft position sensor. Failure to follow this procedure will result in improper camshaft position sensor alignment. This will result in the fuel system being out of time with the engine, possibly causing engine damage.

2. Transfer oil pump intermediate shaft from old camshaft position sensor housing to replacement housing.
3. Install camshaft position sensor housing so drive gear engagement occurs when arrow on locator tool is pointed as shown in the illustration. This step will locate the camshaft position sensor electrical connector in the pre-removal position.
4. Rotate Syncro Positioning Tool T96T-12200-A clockwise slightly. This will engage the oil pump intermediate shaft. Push downward adjusting the Syncro Positioning Tool T96T-12200-A until the syncro gear engages the camshaft gear.
5. Install hold-down clamp and retaining bolt and tighten bolt to 20-30 N-m (15-22 lb ft).
6. Remove Syncro Positioning Tool T96T-12200-A.
7. Install camshaft position sensor and retaining screws. Tighten screws to 2.5-3.5 Nm (22-30 lb in).

CAUTION: If camshaft position sensor electrical connector is not positioned properly, DO NOT reposition the connector by rotating the camshaft position sensor housing. This will result in the fuel system being out of time with the engine, possibly causing engine damage. Remove the camshaft position sensor housing and repeat installation procedure, beginning with Step 1.

8. Connect fuel charging wiring connector to camshaft position sensor.
9. Connect battery ground cable.
