How to Replace the O2 Sensor in a 95 Pontiac Bonneville SSEI
- 1). Raise the hood of the Bonneville. Locate the oxygen sensor threaded into the exhaust manifold near the front of the engine compartment.
- 2). Pull the electrical connection apart to disconnect it from the sensor. Remove the sensor with a wrench.
- 3). Coat the threads of the new sensor with electrical anti-seize compound. Install it by hand to avoid cross-threading. Torque the sensor to 30 foot-pounds with a torque wrench.
- 4). Push the electrical connector together until it clicks. Lower the hood.
