Heated Oxygen Sensor Replacement - Bank 2 Sensor 2

Heated Oxygen Sensor Replacement - Bank 2 Sensor 2

Removal Procedure

1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle   (See: Maintenance/Vehicle Lifting/Service and Repair).
2. Disconnect the bank 2, oxygen sensor 2 (4), electrical connector from the engine wiring harness connector.

Caution:  Refer to Heated Oxygen and Oxygen Sensor Caution   (See: Service Precautions/Heated Oxygen and Oxygen Sensor Caution).

Caution:  Refer to Excessive Force and Oxygen Sensor Caution   (See: Service Precautions/Excessive Force and Oxygen Sensor Caution).

3. Remove the bank 2, oxygen sensor 2 (4), from the catalytic converter.

Installation Procedure

Note:  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.
