Ive been trying to get ready to smog my car, and ive been having some difficulties doing so. So i had a catless dp on before removing and being put back to stock, but this code has been popping up every test drive. It show up as bank 1 sensor 2 code unknown, ive swapped the downstream 02 sensor twice now, and it still shows up as my last code to get rid of. I dont know if anyone has dealt with this code or similar issue, but it would really help with any input. Ive swapped the fuse for the heater circuit and also swapped the upper 02 sensor clearing other codes but even so the code still want to stay.
Any input is welcomed
