You have to post the 4 digit codes. As you learned, just because a code pinpoints that a particular sensor is detecting a problem, doesn't mean that particular sensor is faulty. That's why you have to do some diagnostics and have the knowledge of the particular vehicle your working on to determine what exactly is causing the issue. So re-scan the SUV and post the codes here and we can try to help further.
The code that I am getting is P0171 saying that the system too lien bank one
Which told me that mass air flow sencer was bad so I put a new one on the suv then it said that the map sencer was bad so I put a new one on the suv now I am being told that the pvc valve is bad
We had a similar issue recently ended up being the egr valve. I think it was the same code.
