Removal & Installation
The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used.
- Locate the oil pressure sensor on the engine.
- Disconnect the sensor electrical harness.
- Unfasten and remove the sensor from the engine.
- Coat the new sensor with Teflon® tape or electrically conductive sealer.
- Install the sensor and tighten to 15 ft. lbs. (20 Nm), for 2.3L engines tighten to 11 ft. lbs. (15 Nm).
- Attach the sensor-s electrical connector.
- Start the engine, allow it to reach operating temperature and check for leaks.
- Check for proper sensor operation.
- Test and verify the engine oil pressure. If no or insufficient pressure exists, oil pressure problem exists and gauge and sensor are operational, repair oil pressure problem.
- Check the appropriate fuse before attempting any other diagnostics.
- Unplug the sensor electrical harness.
- Using an ohmmeter, check continuity between the sensor terminals.
- With the engine stopped, continuity should not exist.
- With the engine running, continuity should exist.
- If continuity does not exist as stated, the sensor is faulty.
