I have been running with bad sensors for a few months because I haven't had time to change them. And yes, I know how horrible that is. But I replaced all 4 today, clears the codes and ran it up the road and then got the codes. Any suggestions?

 

Unfortunately some of us have had Bosch O2 sensors be bad out of the box. That could be the case here, especially given the codes you're seeing.

If you bought them locally just return it and get another one. That's why I don't buy O2 sensors online. If one is bad out of the box I want to be able to exchange it same day and not have to wait.

Other than that you might check to confirm that the harness-side connector is nice and clean.

 

That's kind of what I was thinking. Tomorrow I'm going to swap the front 2 and see if I get it on bank 2 sensor 1. I'll also check all the connections. Thank you
