I plug up my Osiris tuner just to clear my O2 sensor codes for my exhaust until I get a tune and I got this third code, P0605 Internal Control Module Read Only Memory (ROM) Error. As far as I could find, it has something to do with the power output of the ECM, correct me if I'm wrong. I was just curious if this was something I should be worried about and bring to the dealership's attention. Any help or advice would be greatly appreciated. Thanks!
