• Q: How to replace the Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1 on 2005 Cadillac SRX?

  A: In order to replace the Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1, first remove the left side air inlet panel. Make sure the HO2S and the O2S are treated gently while maintaining the in-line electric connector and the louvered end clean of grease, dirt, contaminations, and never use in cleaning solvents. It should be noted that Bank 2 here means left bank and the removal is easier when the institution temperature will be more than 48°C (120°F. Unplug the HO2S connector and pull it out from the wiring harness bracket. Lift and hold the vehicle as you take out the HO2S. For installation, it is also required to apply anti-seize compound P/N 5613695, or an equal one to the threads of the used sensor, as new sensors which have to be used should already have this compound applied to it. Mount the HO2S and tighten it to 40 Nm (30 lb ft). Lower the vehicle then; Connect the HO2S electrical connector to the wiring harness bracket; Connect the said. Lastly, replace the left side air inlet panel.
