Removal Procedure

Important:  Bank 2 are cylinders 2, 4, and 6 which are closest to the front of the vehicle.

1. Turn the ignition OFF.
2. Disconnect the bank 2 heated oxygen sensor 2 harness connector (2) and disconnect from the retaining bracket.
3. Raise and support the vehicle. Refer to Vehicle Lifting.
4. Remove the left transmission mount just enough to gain access to the heated oxygen sensor.
5. Remove the heated oxygen sensor wiring harness bracket and bolt.

Caution:  Removal of the sensor is easier if the exhaust system is warmed up slightly. Be careful that it is not too hot to work on safely.
Applying penetrating oil to the threads while moving the sensor back and forth will also aid in removal and will decrease the chance of
exhaust pipe thread damage
.
