SES light, error code P0030?
About two weeks ago, my service engine soon light came on. It is yellow. I recently got it scanned and the code it is throwing is P0030 (heater control circuit, bank 1, sensor 1).
I searched the forum and couldn't find much information on it. Has anyone else had to deal with this code? From what I can gather, it has something to do with smog/sensors. Is this something I should deal with immediately, will it harm the car or affect the performance? Bottom line, what is it exactly?
