How to replace the Heated Oxygen Sensor (HO2S) for Bank 2 Sensor 2 on 2010 Buick Enclave?

To change the heated Oxygen Sensor (HO2S) for bank 2 sensor 2, first, lift and raise the vehicle securely. Eliminate the connector placement warranty (CPA) retainer and remove the ho2s electrical connector from the engine wiring spanner electric connector. Then, take out the ho2s out of the Exhaust Pipe. If re-installing the old sensor, coat the threads with anti-seize compound gm p/n 12377953 or an equivalent, since it uses in the ho2s threads a special anti-seize composition containing liquid graphite and glass beads to make future removal easier. Mount the ho2s back onto the Exhaust Pipe and screw it in with 42 nm (31 lb ft). Connect ho2s electrical connector to the engine wiring harness electrical connector and balance retainer cpa before returning the car.
