0303 code...how to fix?
Just pulled an 0303 code (left bank heated O2 sensor) and I have no idea where to even begin with this one. It said something about wiring maybe doing it, so I'd like to check the voltage thats running through it but I have no idea where it's at. If its not that, how much do these run and are they hard to replace? Thanks for you help.
