I have 2015 RAM 3500 with the 6.7 ho and Aisin trans. I had a P20E8 code resulting in a new DEF pump. Now it has P202C and P21C4 codes after the new pump was installed.Any help or advice would be greatly appreciated. The truck only has 43000 miles and I need it badly for my work. Dealer is of no use whatsoever ! They only want to sell me a new truck
