02 Sensor: Installation

  1. After removing the sensor, the threads must be cleaned with an 18 mm X 1.5 + 6E tap. If reusing the original sensor, coat the sensor threads with an antiseize compound such as Loctite 771- 64 or equivalent. New sensors have compound on the threads and do not require an additional coating. Tighten the sensor to 28 N.m (20 ft. lbs.) torque.
  2. Connect the heated oxygen sensor electrical connector.
  3. Install the wiring clip to the heat shield (Fig 2 ).
