• Q: How to service and repair oxygen sensors on 2000 Buick Park Avenue?

  A: The removal process of oxygen sensors becomes easier at engine temperatures higher than 48°c (120°F). Removal of oxygen sensors requires the j 39194 (Oxygen Sensor wrench) to do the job while users must protect the pigtail and connector which won't separate from the sensors. The threads of reused sensors require application of anti-seize compound p/n 5613695. Begin by removing the fuel injector sight shield then detach the ho2s retaining clip from the bracket before disconnection of the electrical connector tab from the retaining clip. Use the j 39194 to take out the Oxygen Sensor from the rear Exhaust Manifold when the vehicle is raised at work height. The rear ho2s installation requires tightening at 41 n.m (30 lb ft) while reconnecting the electrical connector then securing the retainer before lowering the vehicle to reinstall the fuel injector sight shield. To begin installation on sensor number two raise the vehicle and remove the splash shield before disconnecting the ho2s 2 electrical connector retaining tab from the ho2s electrical connector. Use the j 39194 tool to remove the Exhaust Pipe Oxygen Sensor before installing a new one which needs to be tightened to 41 n.m (30 lb ft). Then reconnect all electrical connectors and retaining tabs before putting back the splash shield and lowering the vehicle.
