My 2014 1500 threw a CEL when I started it to leave work yesterday. I took it to a parts store so the can see what code caused the light. The guy showed me I had one code and it is p0456 for a small leak in the evap system. He said it could be a loose gas cap to a leaky hose or other things. How long is the warranty on these parts? my truck is at 42,000 miles now. Is this something I can self diane or would I be better off taking it to a dealer or a local shop? I'm very mechanical but my previous truck for over 10 yrs was a 2nd gen cummins so I'm not to sure of the emissions equipment on a gas powered truck. I did remove the gas cap and retightened it, I'll give a few days to see if the light goes off.
