I have a 2008 2500 with 6.7 turbo, The Mil keeps coming on, I hooked a OBD and it reads P2A00, What does P2A00 mean, is it something serious, so far the light has came on and the truck has less than 2000 miles on it and I live 75 miles from the dealer, so i cant run to them everythime the light goes off, Any info would be a big help to me.
