Well, your vehicle has either 3 or 4 of them. They are located in the exhaust system. One in either Exhaust Manifold at the engine and the other one or two are located either one infront of the Catalytic Converter and one after or behind it. Or if you have two cats they are in front of each cat.
If you have the code post it and can tell you which sensor to replace or the possible causes of the code.
