Crankshaft Position Sensor: Service and Repair
Crankshaft Sensor Replacement:
1. Disconnect the negative battery cable.
2. Disconnect the crankshaft sensor electrical connectors from the engine wiring harness.
3. Raise vehicle and support properly.
4. Remove the upper and lower damper shield assemblies.
5. Rotate the crankshaft by hand to position the metal vane of the shutter (attached to rear of the damper) outside of the sensor air gap.
6. Remove the crankshaft sensor retaining screws and remove the sensor.
7. Position the crankshaft sensor assembly on bracket.
8. Install the sensor retaining screws but DO NOT tighten them at this time.
9. Install the crankshaft sensor gauge (Ford part #T89P-6316-AH, or equivalent) to the outside surface of one vane of shutter.
NOTE: Gauge is metallic and will conform to the shape of the vane.
10. Rotate the crankshaft by hand to align shutter vane with gauge into sensor air gap.
11. Push sensor housing inward to contact gauge and tighten retaining screws to 22-31 lbs. in. (2.5-3.5 N-m).
CAUTION: This is a critical torque. Over tightening fasteners can cause damage to the timing sensor.
12. Rotate the crankshaft by hand to position shutter vane with gauge outside of air gap. Remove the magnetic gauge.
13. Install upper and lower damper shields and tighten fasteners.
14. Lower vehicle and route sensor wiring harness and connect both electrical connectors.
15. Connect the negative battery cable.
