there are 2 o2 sensors they are both under the car on the passanger side. one is just in front of the cat towards the engine and the other is just behind the cat. easy to locate if you have access to a lift to get under the car. just follow the exhaust back to the engine and you can miss them..
they are located in the exhaust system Where ? how many 02 sensors on a 2003 Pontiac Montana
The o2 sensors on the 2002 Pontiac Grand Am GT are found screwed into the exhaust pipe. There are 2 of these on the 2002 Grand Am GT.

Under the cover there should be two screws. On my '02 Firebird they were a star screw. Taking those two screws off let the panel come out.
02 sensors are located on your exhaust pipes that come out of your heads on your engine there could be up to 4 02 sesors on a vehicle.Bank 1 or 2 means your different heads Then you will have upstream and downstream and that means the location of the 02 sensors
There are multiple O2 sensors on a 2002 Chevy truck. They are all located on the exhaust system. There will be pre catalytic converter and post catalytic converter sensors.
the 02 sensor on my 1994 4.9 6 cyl is located just pass the first converter in the exhaust pipe and the egr is to the right of the air tubes coming from the air box on the intake other sensors depend on which ones as to location
Most oxygen sensors are heated oxygen sensors.
The 02 sensors are in the exhaust pipes but don't know about the updraft sensors.
The vehicles computer relies on the information from the 02 sensors and other sensors to adjust the engine for peak performance.
The o2 sensors screw in. There is a special socket for removing the 02 sensors with a slot in the side to clear the wiring.
There are 2 upstream 02 sensors just behind the exhaust manifolds, threaded into the exhaust pipes, one on each side. There are 2 downstream 02 sensors just behind the catalytic converters, one on each side as well.
