Maybe a silly question but did you clear the codes with the generic code reader or are you thinking they would just clear themselves? Most Generic code readers will clear the codes, I think the codes might automatically clear if you drive it for a few miles without the computer sensing the fault anymore, at least for the check engine light, but the code will probably be locked in the ECU until cleared.
