I recently removed one read O2 sensor and replaced it with a wide band O2 and i'm getting all kinds of weird codes i don't understand why i would get a bank 1 sensor 1 and bank 2 sensor 1 code. I posted a picture any help would be great. Ignore the tps code i need to change it
Sorry this is for my 2002 Chevy Tahoe with a 5.3L

Those are pending history codes from what it looks like, clear them and see what comes back.
Removing just a rear o2 sensor should only cause that code to come up.
So last night I turned off all the rear o2 sensor codes and that cleared up that code but this morning heading to work the bank 1 sensor 1 and bank 2 sensor 1 heating code came back on. Is it possible that the heating circuit is all connected together and by removing the one rear o2 i broke the circuitQuote:

If you don't feel like sifting through all of the DTCs in the Engine Diagnostics tab, you can always wait for a code to set, look up the code on the Engine Diagnostics tab and disable it. As long as it pertains to the catalyst monitoring system.
