Pre and Post Converter

Removal Procedure

Notice: Remove oxygen sensors with the engine temperature above 48°C (120°F). Otherwise the oxygen sensors may be difficult to remove.

Notice: Take care when handling oxygen sensors. The electrical connector and louvered end must be kept free of contaminants. Do not use cleaning solvents on the sensor. Do not drop or mishandle the sensor.

1. Raise and support the vehicle.
2. Disconnect the pre- or post-converter oxygen sensor connector.
3. Remove the pre- or post-converter oxygen sensor.

Installation Procedure

Notice: A special anti-seize compound is used on the oxygen sensor threads. New service sensors should already have the compound applied to the threads. Coat the threads of a reused sensor with anti-seize compound P/N 5613695 or equivalent.

1. Install the pre- or post-converter oxygen sensor. Tighten the Pre or Post HO2S sensor to 41 Nm (30 lb ft).
2. Connect the pre- or post-converter oxygen sensor connector.
3. Lower the vehicle.
