Bank 2 Sensor 2

REMOVAL PROCEDURE





NOTE: Use care in handling the HO2S. Refer to HO2S Pigtail Notice in Cautions and Notices.

IMPORTANT: The heated oxygen sensor may be difficult to remove when the engine temperature is below 48°C (120°F). Excessive force may damage the threads in the exhaust manifold or exhaust pipe. It may be necessary to lower the exhaust system in order to gain sufficient access to a HO2S and/or the connector. Refer to Engine exhaust.

1. Raise the vehicle.
2. Disconnect the HO2S electrical connector.




3. Carefully back out the heated oxygen sensor.

INSTALLATION PROCEDURE





IMPORTANT: Use special anti-seize compound on the heated oxygen sensor threads. The compound consists of graphite suspended in fluid and glass beads. The graphite burns away, but the glass beads remain, making the sensor easier to remove. New or service sensors already have the compound applied to the threads. If you remove an oxygen sensor and if for any reason you must reinstall the same oxygen sensor, apply the anti-seize compound to the threads before reinstallation.

1. Coat the threads of the heated oxygen sensor with the anti-seize compound P/N 5613695, or the equivalent if necessary.

NOTE: Refer to Fastener Notice in Cautions and Notices.

2. Install the heated oxygen sensor.

Tighten
Tighten the HO2S to 41 N.m (30 lb ft).




3. Connect the HO2S electrical connector.
4. Lower the vehicle.
