They are about 3 to 4 inches long with an electric wire on them. There is 4 of them on your truck and they are screewed into the exhaust pipe system. Start where the exhaust bolts to the engine and you will see 2 of them in that area, Then work your way back the exhaust system towards the muffler and you will see 2 more of them.
When you are under the truck, look on the driver side of the oil pan.
There are 4. Two upstream (bank1) two downstream (bank2).
You probably mean the NOX sensor, it is the exhaust in front of the converter and the V8 has at least two of these sensors, easy to get to after you get under the truck, just unplug the wire and remove from the exhaust
Two,one in front of the catalytic converter & one behind it.
there are 2 oxygen sensors on the 03 Chevy cavaliers. one is located right by the exhaust manifold, this is you upstream. then the other, down stream, is located right behind u Cadillac converter. hope this helps!

There are several O2 sensors on that vehicle and they are all threaded into the exhaust system at various points.
