Only finding one o2 sensor on my 03 dakota

My grandfather and I have been looking and looking for more then the one o2 sensor on my truck. The one we found is on the passenger side out put. Does anyone know where to find the bank one sensor one o2 sensor? Or does this only have one sensor? Any help would be much appreciated!

Bank one sensor one would be the first sensor closest to the engine, and if it only has one sensor that would be it.

It’s got a 4.7 l v8 in it. The only one sensor we can find is on the passenger side on the output

Typically your o2 sensors will be before and after the catalytic converter / converters. Here is a 49 state aftermarket setup for your 03' 4.7.

Notice the o2 bungs on the top of the pipe. If your truck isn't a california truck, your o2's will be in roughly the same areas.

If you have California emissions, you should have a pipe that looks like this:

It's close to the frame coming downward. They are a BICH to get at.
