WARNING: This page is about a different car, the 2005 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
- Turn the ignition OFF.
- Disconnect the HO2S-1 harness connector.
- Remove the sensor harness and connector from the attachment clip.
- Use a liquid penetrate before removing the sensor.
- Remove the H02S-1 using the J 39194-C ,or equivalent. See Special Tools .
NOTE:
The HO2S uses a permanently attached pigtail and connector. This pigtail should not be removed from the HO2S. Damage or removal of the pigtail or connector could affect proper operation of the sensor.
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.
