Heated Oxygen Sensor Replacement - Bank 2 Sensor 1

Removal Procedure






Notice: Refer to Heated Oxygen and Oxygen Sensor Notice.

Notice: Refer to Excessive Force and Oxygen Sensor Notice.

1. Raise the vehicle. Refer to Vehicle Lifting.
2. Disconnect the heated oxygen sensor (HO2S) electrical connectors. Note the harness routing and retainers for reassembly.
3. Remove the right side catalytic converter.
4. Remove the HO2S (1).

Installation Procedure






Important: Use special anti-seize compound on the HO2S 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 HO2S with the anti-seize compound P/N 5613695, or the equivalent if necessary.

Notice: Refer to Fastener Notice.

2. Install the HO2S (1).

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

3. Install the right side catalytic converter.
4. Connect the HO2S electrical connector. Ensure that the harness is routed and retained as noted during disassembly.
5. Lower the vehicle.
