Parts
- Camshaft Position Sensor × 1 — 90919-05060 or equivalent
- Camshaft Position Sensor O-ring × 1 — Typically included with sensor
Preparation
- Park vehicle on level surface and engage parking brake
- Allow engine to cool completely for at least 30 minutes
- Disconnect negative battery terminal and wait 3 minutes before proceeding
- If equipped, remove engine cover by pulling upward on four corner clips
- Locate the camshaft position sensor on the right (passenger) side of the cylinder head near the timing chain cover
Procedure
- 1Disconnect electrical connectorLocate the camshaft position sensor electrical connector. Press the locking tab and pull the connector straight off the sensor. Do not pull on the wiring harness itself.
- 2Remove sensor mounting boltUsing a 10mm socket, remove the single bolt securing the camshaft position sensor to the cylinder head. Keep the bolt in a safe location for reinstallation.Torque specCamshaft Position Sensor10 Nm (7 lb-ft)
- 3Extract sensor from cylinder headCarefully pull the camshaft position sensor straight out of the cylinder head. Use a slight twisting motion if needed to break the O-ring seal. Avoid excessive force or angling which could damage the sensor bore.
- 4Inspect sensor bore and clean mounting areaInspect the sensor bore in the cylinder head for debris, oil sludge, or metal particles. Clean the mounting surface on the cylinder head with a clean shop towel. Ensure no debris falls into the sensor bore opening.
- 5Prepare new sensorRemove the new camshaft position sensor from packaging. Verify the new O-ring is properly seated in the groove on the sensor body. Apply a light coat of clean engine oil to the O-ring to ease installation and prevent tearing.
- 6Install new sensorInsert the new camshaft position sensor straight into the cylinder head bore. Push firmly until the sensor is fully seated and the mounting flange contacts the cylinder head surface. Ensure the sensor orientation matches the bolt hole alignment.
- 7Install and torque mounting boltHand-thread the mounting bolt into the cylinder head, ensuring it engages properly without cross-threading. Using a torque wrench, tighten the bolt to the specified torque value of 10.0 Nm (7.0 lb-ft). Do not overtighten as this can crack the sensor housing.Torque specCamshaft Position Sensor10 Nm (7 lb-ft)
- 8Reconnect electrical connectorPush the electrical connector firmly onto the camshaft position sensor until you hear and feel a positive click, indicating the locking tab is fully engaged. Gently tug on the connector to verify it is locked in place.
- 9Reinstall engine coverIf removed, align the engine cover with the four mounting grommets and press down firmly at each corner until the clips snap into place.
- 10Reconnect battery and clear codesReconnect the negative battery terminal and tighten securely. If using an OBD-II scanner, clear any stored diagnostic trouble codes related to the camshaft position sensor (P0340, P0341, P0342, P0343, P0344).
Reassembly
- Ensure all electrical connectors are fully seated and locked
- Verify the sensor mounting bolt is torqued to specification
- Confirm engine cover is properly installed on all four mounting points
Verification
- Start the engine and verify it runs smoothly without misfiring or rough idle
- Confirm the check engine light does not illuminate after 30 seconds of running
- Using an OBD-II scanner, verify no camshaft position sensor codes are present
- Test drive vehicle to confirm normal operation and no loss of power
- Re-scan for codes after test drive to ensure repair is successful
