Im, not sure which 02 sensor has the prob?? The code is( P0038 heater CKT high ) I cleared it twice, it keeps coming back. I have a generic code reader, Im a laid off GM auto mechanic, on GM vehicles they usually say bank 1 or bank 2 etc. Its a 2004 with 48k, I wonder if it's coverd under powertrain warr.?? :roll

Has anyone else had this code set ??????????????
