The oxygen sensor is located in the flow of exhaust and there will be two. the first is at the exit of the exhaust manifold where the head pipe attaches before the converter and the other is just after the cat converter.

- There are only two oxygen sensors for your car, front and rear. Are you sure it's not a different sensor?
