OBD2 help
so my 01 s4 had two codes which caused a cel, the codes were 1113 and 1131. According to the reader it was one of my o2 sensors, i spent the day yesterday replacing that and cleared the cel, it popped back on today and when i checked it again 1131 was the only code. Does anyone have any idea what that code is for the reader wont say which this one is for. Thanks
