  3. Remove the sensor harness and connector from the attachment clip.
  4. Use a liquid penetrate before removing the sensor.
    5. NOTE: Removal of the sensor is easier if the exhaust system is slightly warmed up. Be careful that the exhaust is not hot to work on safely. Moving the sensor back and forth while applying penetrating oil to the threads will aid in removal and will decrease the chance of exhaust pipe thread damage.
  5. Remove the H02S-1 using the J 39194-C  ,or equivalent. See Special Tools .
