Depends on which engine you have! 4 or 6 cyl.???? V6 pass. side is bank 1, 4 cyl only one bank so it is #1. Now, is it sensor bank one sensor 1 or bank 1 sensor 2?? We need the actual code number(s).

4 cylinder

There is only one bank but two sensors! Sensor #1 is at the engine, sensor #2 is behind the cat. converter. Post trouble code(s).

It read "Bank one, sensor one".....that's an upstream sensor, right?
