Please answer the question. "How do you change an oxygen sensor in a 2002 Pontiac Bonneville
In the 1989 Grand Prix, the oxygen sensor is in the tail pipe. Look for a wire that is plugged into both the tail pipe and the undercarriage of the vehicle.
The 1991 Pontiac Grand Prix oxygen sensor is located on the outside of the air filter housing. You will find the sensor on the back side of the air filter housing.
The oxygen sensor on a 1996 Pontiac Grand Am is found near the catalytic converter. It will be place on the piping which leads to the catalytic converter.
The 2003 Mercury Grand Marquis came equipped with the 4. 6L V8. Oxygen (O2) sensor locations are upstream and downstream (before and after the catalytic converters).
That would be the sensor after the catalytic convertor.
In the exhaust pipe, near the engine.
OEM stands for original equipment manufacturer. The Oxygen sensor senses amounts of oxygen in the exuast to adjust the fuel mixture acordingly.
