How to replace the Heated Oxygen Sensor - Bank 2 Sensor 2 (1500 Series) on 2009 GMC Sierra 1500?

The first task for the Heated Oxygen Sensor - Bank 2 Sensor 2 (1500 Series) replacement requires you to lift and stabilize the vehicle. Disengage the connector position assurance (CPA) retainer while separating the HO2S electrical connector from the HO2S electrical connector of the engine wiring harness. The next step requires removal of the HO2S electrical connector clip from its position on the engine harness clip before extracting the HO2S . The threads of the HO2S need to receive anti-seize compound preparation using GM P/N 12377953 or equivalent to ease removal since the sensor employs a unique anti-seize compound of liquid graphite and glass beads for thread compatibility. You should install the HO2S and secure it with 42 Nm torque (31 lb ft). Secure the engine harness clip with the HO2S electrical connector clip and then link the engine wiring harness electrical connector to the HO2S electrical connector before using the CPA retainer to finish the installation process when lowering the vehicle.
