Does anyone have an idea of what these codes could be? I have a catless dp but I already disabled the rear O2 sensors.

I'm pretty sure it's referring to the heating element that's part of the O2 sensor. Are your O2 sensors still plugged in? I'm curious if the tune just tells the ECU to not read the value and doesn't disable the component checks that's part of the open loop procedure on startup.

Unless the shop that did my downpipe damaged my O2 sensor it should be plugged in and all good. I did put and extension on it to maybe help fool it from throwing a code but that never worked. The car runs perfectly fine btw.
