UGH. Can't figure out what is throwing these O2 sensor codes.

I had these mixed up on my swap as well, they are opposite of what you think.

Easiest way to find out is disconnect one. Wait for it to throw an O2 heater code and then check which bank the code is to see if it matches the bank of the disconnected O2 sensor.

If they are ok the next step is to smoke test the intake system.

Hey y'all been super busy and forgot to update this thread last week. I swapped the O2 sensors and everything is peachy now. [emoji106] Thanks so much for the feedback, always nice to have a really simple solution to a problem for once. [emoji3]
