I am going to put a wideband in place of one of my rear O2's. I already have P420 deleted as I don't run cats, but what if any, other codes need to be deleted when I unplug and remove the rear O2's?

Thanks and I DID search

 

i just went through the whole list of trouble codes looking for anything pertaining to rear o2s and shut them all off.
