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

A vehicle-mounted approach with proper support must be implemented before initiating Bank 2 Sensor 1 Heated Oxygen Sensor (HO2S) replacement. First strip the harness retention clip holding the HO2S then detach the sensor from the clip. The sequential installation begins by removing the HO2S electrical connector after separating the CPa retainer followed by disconnecting the Bank 2 sensor. During installation of the HO2S users must apply special anti-seize compound with liquid graphite and glass beads to its threads. new and replacement service sensors arrive with pre-applied anti-seize compound. When reinstalling an old HO2S sensor always apply anti-seize compound GM P/N 12377953 or alternative equivalent to the threads. The bank 2 HO2S needs to be installed tightly to reach a torque of 42 N.m (31 lb ft). Reconnect the HO2S electrical connector then install the CPA retainer followed by repositioning the HO2S into the harness clip before completing launch of the engine harness as you lower the vehicle.
