Heated Oxygen Sensor Replacement - Bank 1 Sensor 2

HEATED OXYGEN SENSOR REPLACEMENT - BANK 1 SENSOR 2

REMOVAL PROCEDURE




1. Raise the vehicle. Refer to Vehicle Lifting i.

NOTE:
- Refer to Heated Oxygen and Oxygen Sensor Notice.
- Refer to Excessive Force and Oxygen Sensor Notice.

2. Disconnect the heated oxygen sensor (HO2S) electrical connector. Note the harness routing and retainers for reassembly.
3. Remove the HO2S (1).

INSTALLATION PROCEDURE




1. Coat the threads of the HO2S with the anti-seize compound P/N 5613695, or the equivalent if necessary.

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.

2. Install the HO2S (1).

NOTE: Refer to Fastener Notice.

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

3. Connect the HO2S electrical connector. Ensure that the harness is routed and retained as noted during disassembly.
4. Lower the vehicle.
