OBD CODES
HAVE A QUESTION FOR ANYONE... I HAVE A 2005 RAM WITH A 5.7 HEMI. I AM THROWING A P0420 CODE... O2 SENSORS? CAN IT BE DETERMINED WHICH ONE IT IS. AND HOW MANY O2 SENSORS ARE THERE. THE TRUCK HAS 62,000 MILES ON IT. I JUST REPLACED THE EGR ABOUT 1500 MILES AGO, NOW I AM TROWING THIS NEW CODE. ANY AND ALL SUGGESTIONS WOULD BE DEEPLY APPRECIATED. THANKS.
