How to replace the Heated Oxygen Sensor (HO2S) Bank 1 Sensor 2 on 2005 GMC Sierra 1500?

The replacement of the Heated Oxygen Sensor (HO2S) Bank 1 Sensor 2 requires a vehicle lift to support the vehicle's body. Disconnect both the fuel composition sensor electric connector and connector position assurance (CPA) retainer if present. Remove the HO2S electrical connector from its fuel line clip when a fuel composition sensor exists on the vehicle. Separate the HO2S electrical connector from the vehicle in models with either a 4.8L or 5.3L engine while 6.0L engines require the same action. Remove the HO2S. New sensors arrive pre-coated with anti-seize compound GM P/N 12377953 so use this product to coat old sensor threads when reinstalling. Install the HO2S utilizing a torque of 42 N.m (31 lb ft). The electrical connector of the HO2S needs attachment for both 6.0L or 4.8L and 5.3L motor vehicles. To install the HO2S electrical connector you must connect it to the fuel line clip before removing the CPA retainer to reconnect the fuel composition sensor electrical connector. Finally, lower the vehicle.
