Hello cpbarbour: My name is Roger and I will help. If the sensor is precat? The sensor will be directly in front of the catalytic converter. Should you need further help please just ask. Please rate the answer you received. Thank You for using Fix Ya. Roger

These are normally located on the exhaust pipe...it could also be the manifold as different vehicle varies.So if it not near the manifold then look further down the exhaust pipe.

Location oxygen sensor 2002 chevy monte carlo


I believe, depending on the engine...you have 3 O2 sensors in the exhaust stream. Do NOT go to the Chevy Dealer for repair...instead find a good local mechanic and save approx $150
Good Luck

Location of oxygen sensors


I think there is more than two. Either way, they are located in the exhaust system. The pre-cat sensors are in the head pipes, just below the exhaust manifold, and then there will be one right behind the catalytic converter. You will need a 7/8 inch wrench or possibly a special O2 socket.

you should have three oxygen sensors on your car, one for each bank of three cylinders; should be towards the Y pipe on each exhaust manifold. Additionally you should have one on the exhaust pipe before the cadilitic converter.
