12 is start 55 is end of codes. The codes you have are actually 47 and 31. Code 47 indicates low charging circuit voltage, check the alternator, wiring to the alternator or the belt. Code 31 indicates you have a problem with the evaporative emissions circuit. You could have a loose gas cap or a bad solenoid on the evap. emissions system. I hope this clears it up.
