check engine light is on

Post by danddmodsandrods »

i installed a power puck in my 2012 ram 3500 truck. i disconnected both batteries before the install, the check engine light comes on and the codes it sets is p020a, b, c, d, e, f, for injection timing for every cylinder. i disconnected the power puck and drove the truck 100 miles no light, i installed the puck again, with the batteries unhooked, and the light came on again, same codes. the truck runs great, good power good fuel conomy, well not good it only gets 16.2 but thats better than the 14.5 it was getting. any ideas?
