Heated Oxygen Sensor Replacement - Bank 1 Sensor 2

Heated Oxygen Sensor Replacement - Bank 1 Sensor 2

Removal Procedure




1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle (Service and Repair).

Caution: Refer to Heated Oxygen and Oxygen Sensor Caution (Heated Oxygen and Oxygen Sensor Caution).

Caution: Refer to Excessive Force and Oxygen Sensor Caution (Excessive Force and Oxygen Sensor Caution).

2. Disconnect the bank 1, oxygen sensor 2 (2), electrical connector from the engine harness.
3. Remove the bank 1, oxygen sensor 2 (2), in the catalytic convertor.

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.




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

Caution: Refer to Fastener Caution (Fastener Caution).

2. Install the bank 1, oxygen sensor 2 (2), in the catalytic convertor.

Tighten the oxygen sensor to 41 Nm (30 lb ft).

3. Reconnect the bank 1, oxygen sensor 2 (2), electrical connector to the engine wiring harness electrical connector.
4. Lower the vehicle.
