I found an old thread somewhere this morning where a technician was asking for the subcode and he made it sound as if it might be easy to fix if he just knew the subcode. Mine is error 20, subcode 02.Of course the thread ended there. If you get around to taking it in, would you mind teffibly letting me know what they found? Its 100 miles to a repair shop for me, that "might" be able to fix it...
