So I went to the carwash, about 2 miles after leaving the wash my "Service Engine Soon" light came on... I went into the troubleshooting mode on the Accessport and there was 2 codes, one was the MAF sensor was faulty and or needed to be cleaned, the other just says ECU and when clicked on says " No Description Available" . The car runs and drives the same as it did before. What could cause the ECU "code" since it does not specify what code it is? Could it possibly be water got into someplace it shouldn't have? Any help would be greatly appreciated!
