I recently failed inspection due to OBD codes PO431, PO141 and PO1751. I was wondering how expensive these repairs would be? I drive a 2000 Mitsubishi Diamante/Automatic/6 cylinder/125000 miles. I also noticed the check engine soon light will not go off. Can my local mechanic turn off that light or does it have to be done by the dealer?
