light with that code...(please correct me if I'm wrong)...it's been a while since I've seen that. That code can be set if you really push the car hard....(i believe that's how I set it before)
The DTC's I've been getting was for an O2 sensor correction factor. THis is due to either bad cats or bad O2 sensors or both. It is set when the ECU doesn't see a proper secondary O2 sensor voltage after the inline cats.
