  1. Remove any dirt, grease, or other impurities from the mounting surface.
  2. Position the sensor horizontally on the mounting surface.
  3. Point the arrow on the sensor toward the front of the vehicle.
    4. NOTE: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure.
