How to replace the Heated Oxygen Sensor (HO2S) for Bank 1 Sensor 2 on 2009 Cadillac SRX?

Begin replacement of the Heated Oxygen Sensor (HO2S) for Bank 1 Sensor 2 by turning off the ignition and safely raising the vehicle. Separate the HO2S electrical connector while carefully extracting the wiring harness from the transmission case without causing harm to the permanently installed pigtail and connector. Easier sensor removal requires an engine temperature above 48°C (120°F) before starting work. Add anti-seize compound P/N 5613695 along with an equivalent material to reused sensors' threads since service sensors from the factory receive this compound automatically. After tightening the HO2S installation to 40 Nm (30 lb ft) torque measure use the same steps to return the electrical connector and wire harness to the transmission case before lowering the vehicle down.
