• Q: How to service the Bank 1 Sensor 2 oxygen sensor on 2000 Cadillac Eldorado?

  A: The first step to service Bank 1 Sensor 2 oxygen sensor involves raising and supporting the vehicle. Eliminate power from the pre- or post-converter oxygen sensor through the electrical connection disconnecting process. Engine temperatures above 48°C (120°F) lead to difficult oxygen sensor removal so sensor replacement should begin when the engine temperature reaches this threshold. Wait until the operating engine temperature reaches above 48°C (120°F) before continuing to remove the pre- or post-converter oxygen sensor. The threads of new service sensors must receive anti-seize compound applicatioin as part of installation but reused sensors should receive this compound P/N 5613695 or equivalent before thread installation. Screw in the pre- or post-converter sensor while maintaining a torque of 41 N.m (30 lb ft). The vehicle's descent concludes with sensor connector installation under the harness heat shield for protection before vehicle lowering.
