Parts
- Camshaft Position Sensor × 1 — Use OEM Ford specification
- O-ring seal (if not included with sensor) × 1 — Included with most OEM sensors
Preparation
- Park vehicle on level surface and engage parking brake
- Allow engine to cool completely if recently operated
- Disconnect negative battery cable to prevent accidental starting
- Locate the camshaft position sensor on the front driver's side of the engine, near the timing chain cover
Procedure
- 1Access the camshaft position sensorOpen the hood and secure it safely. Identify the camshaft position sensor on the front left (driver's side) of the engine block, just below the cylinder head near the timing chain cover. It will have a single electrical connector and one mounting bolt.
- 2Disconnect the electrical connectorPress the locking tab on the camshaft position sensor electrical connector and carefully pull the connector straight off the sensor. You may need to wiggle it gently while pulling. Inspect the connector terminals for corrosion or damage.
- 3Remove the sensor mounting boltUsing a 10mm socket with extension, carefully remove the single bolt securing the camshaft position sensor to the engine block. Keep track of the bolt as dropping it into the timing chain area can cause serious engine damage. Set the bolt aside in a safe location.
- 4Extract the old sensorGrasp the sensor body firmly and pull straight out from the engine block. It may require slight twisting motion to break the O-ring seal. Once removed, note the orientation of the sensor for proper installation of the replacement.
- 5Clean the sensor mounting boreUse a clean shop towel to wipe out the sensor mounting hole in the engine block. Remove any debris, old seal material, or oil residue. A small amount of contact cleaner on a shop towel can help ensure a clean sealing surface. Do not allow debris to fall into the engine.
- 6Prepare the new sensorRemove the new camshaft position sensor from its packaging. Verify it matches the old sensor design. Check that the O-ring seal is properly seated in the groove on the sensor body. Apply a light coating of clean engine oil to the O-ring to aid installation and prevent damage.
- 7Install the new sensorCarefully insert the new camshaft position sensor into the mounting bore, ensuring proper orientation matches the removal position. Push the sensor in until it seats fully against the engine block. The sensor should sit flush without gaps.Torque specCamshaft Position Sensor10 Nm (7 lb-ft)
- 8Torque the mounting boltThread the mounting bolt by hand to ensure proper alignment, then torque to specification using a torque wrench. This ensures proper sensor positioning and prevents damage to the sensor housing or threads.Torque specCamshaft Position Sensor10 Nm (7 lb-ft)
- 9Reconnect the electrical connectorPush the electrical connector onto the new sensor until you hear or feel a positive click, indicating the locking tab has engaged. Gently tug on the connector to verify it is securely locked in place. If desired, apply dielectric grease to the connection for corrosion protection.
- 10Reconnect battery and clear codesReconnect the negative battery cable. If a scan tool is available, clear any stored diagnostic trouble codes related to the camshaft position sensor. This allows you to verify the repair resolved the issue.
Reassembly
- Ensure electrical connector is fully seated and locked
- Verify no tools or shop towels were left in the engine compartment
- Close hood securely
Verification
- Start the engine and verify it runs smoothly without rough idle or hesitation
- Check that the check engine light does not illuminate or return with camshaft position sensor codes
- Use a scan tool to verify camshaft position sensor is providing signal data to the PCM
- Test drive the vehicle to confirm normal operation under various load conditions
- Inspect the sensor area for any oil leaks from the O-ring seal after test drive
