Hall Effect 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.

CAUTION: Prior to removal of the camshaft position sensor (CMP sensor), set cylinder No.1 to 0° top dead center (TDC) of compression stroke. Then note the position of the camshaft position sensor electrical connector. The installation procedure requires the connector be located In the same position.

Removal

1. NOTE: When the battery has been disconnected or reconnected, some abnormal drive symptoms may occur while the powertrain control module (PCM) relearns its fuel trim. The vehicle may need to be driven 16 km (10 miles) or more to relearn the fuel trim.

Disconnect battery ground cable.

2. Disconnect fuel charging wiring connector from camshaft position sensor.

3. Remove camshaft position sensor retaining screws and camshaft position sensor from camshaft position sensor housing.

4. If removing camshaft position sensor housing from the cylinder block, proceed with Removal Step 5. If not removing camshaft position sensor housing, proceed to installation Step 6.

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

6. NOTE: Remove the oil pump intermediate shaft with the camshaft position sensor housing. Remove camshaft position sensor housing from cylinder block.

Installation

1. CAUTION: If the replacement camshaft position sensor housing does not contain a plastic locator cover tool, a special service tool must be obtained prior to installation of the replacement camshaft position sensor. Failure to follow this procedure will result in improper camshaft position sensor alignment. This will result in the ignition system and fuel system being out of time with the engine, possibly causing engine damage.

NOTE: For 3.0L engines, use Syncro Positioning Tool T95T-1 2200-A.

If the plastic locator cover tool is not attached to the replacement camshaft position sensor, attach Syncro positioning tool as follows:

a. Engage camshaft position sensor housing vane into the radial slot of the tool.
b. Rotate tool on camshaft position sensor housing until tool boss engages notch in camshaft position sensor housing.

2. Transfer oil pump intermediate shaft from old camshaft position sensor housing to replacement camshaft position sensor housing.

3. Install camshaft position sensor housing so drive gear engagement occurs when arrow on locator tool is pointed approximately as shown in the illustrations. 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.

6. 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 ignition system and 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.

Install camshaft position sensor and retaining screws. On 3.0L engine, tighten screws to 2.5-3.5 Nm (22-31 lb-in).

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

8. Connect battery ground cable.
