Caution: Refer to Heated Oxygen and Oxygen Sensor Caution in the Preface section.

1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
2. Remove the connector position assurance (CPA) retainer.
3. Disconnect the bank 2 sensor 2 electrical connector.



4. Remove the bank 2 sensor 2 from the catalytic converter.

Note: A special anti-seize compound is use on the heated oxygen sensor (HO2S) threads. The compound consists of liquid graphite and glass beads. The graphite tends to burns away, but the glass beads remain, making the sensor easier to remove. New or service replacement sensors already have the compound applied to the threads. If the sensor is removed from an exhaust component and if for any reason the sensor is to be reinstalled, the threads must have anti-seize compound applied before reinstallation.

1. If re-installing the old sensor, coat the threads with the anti-seize compound P/N 12377953, or equivalent.

Caution: Refer to Fastener Caution in the Preface section.

2. Install the bank 2 sensor 2 to the catalytic converter.

Tighten
Tighten the sensor to 42 N·m (31 lb ft).




3. Connect the bank 2 sensor 2 electrical connector.
4. Install the CPA retainer.
5. Lower the vehicle.
