    Important

    The larger metal contact area of the knock sensor MUST be toward the engine block. DTC P0327 may result if the sensor is installed backwards.

  2. Tighten

    Tighten the knock sensor to 25 N·m (19 lb ft).

    Important

    If the new knock sensor connector retaining clip is going to be used, the old one must be removed from the bracket. Use diagonal cutters to remove.

  3. Lower the vehicle.
  4. Insert the knock sensor retaining clip into the bracket.
  5. Connect the knock sensor harness connector. Push in the connector until a click is heard and pull back to confirm a positive engagement.
