Default Engine code
My 2011 Dodge Ram 1500 has engine code P0456. I don’t see code listed. I have the 5.7 he I and I just change my gas cap at suggestion. What is this code and what do I need to do.

Small leak in the evap system. Could be the gas cap, could be a rotted line. Smoke test would be good here.....
