  1. Disconnect the negative battery cable.
  2. Remove the serpentine drive belt, as outlined in of this guide.
  3. Remove the power steering pump assembly and set aside with the lines attached.
  4. Detach the CMP sensor electrical connector.
  5. Unfasten the retainer bolt, then remove the CMP sensor.
  6. Installation is the reverse of the removal procedure.
3.4L (VIN X) Engine
  1. Disconnect the negative battery cable.
  2. Detach the electrical connector from the camshaft position sensor.
  3. Remove the sensor retainer bolt and carefully pull the sensor from the camshaft carrier. An O-ring seal may hold the sensor in place. Use care not to lose the O-ring.

To install:
  1. Installation is the reverse of the removal procedure.
  2. Before installing a replacement camshaft sensor, lubricate the new O-ring with clean engine oil. Tighten the bolt to just 88 inch lbs. (10 Nm). Do not over-tighten.
  3. Connect the negative battery cable.
3.5L (VIN H) Engine
  1. Disconnect the negative battery cable.
  2. Remove the two coolant recovery tank mounting nuts and lift out the tank to gain access to the camshaft position sensor.
  3. Detach the electrical connector from the camshaft position sensor.

  1. Remove the retaining screw. Remove the sensor by pulling on the sensor connector. Do not pry on the bracket. Do not rotate (twist) the sensor or damage the mounting bracket, if the sensor is to be reused.
To install:
  1. Installation is the reverse of the removal process, observing the following points:
    1. Make sure the sensor bore is completely free of any foreign material (old O-ring, dirt, burrs, etc.).
    2. Make sure that the flange of the sensor bore is not damaged.
    3. Clean all mounting surfaces before reinstalling any components.
    4. If the sensor is being reused, check for damage. Inspect the face of the sensor (bottom of the brass housing) for damage.
    5. Never install a sensor that has been dropped.
    6. Lubricate the O-ring with clean engine oil.
  2. Install the camshaft position sensor and fully seat into its bore. Install the retaining screw and torque to just 80 inch lbs. (9 Nm). Do not over-tighten. Verify the electrical connector is secure.
  3. Install the coolant recovery tank, then connect the negative battery cable.
3.8L Engines
  1. Disconnect the negative battery cable.
  2. Detach the electrical connector from the camshaft position sensor.
