How to replace the Heated Oxygen Sensor (HO2S) Bank 1 Sensor 2 on 2005 Cadillac CTS?

You should start by turning off the ignition and lifting the vehicle for better access prior to the HO2S Bank 1 Sensor 2 replacement. Release the HO2S electrical connector while removing the wiring harness from the transmission case being cautious with the pigtail and connector upkeep. Engine temperatures above 48°C (120°F) present the best conditions for sensor replacement. Apply anti-seize compound from P/N 5613695 or equivalent to sensor threads when using a recycled HO2S before installation. Tighten new and reused sensors to 40 Nm (30 lb ft). The HO2S electrical connector needs reconnection while returning the wiring harness into position on the transmission case followed by lowering the vehicle.
