Started my 2014 1500 and got a check engine light. Have jiffy line out an obd reader and found that it has p0456. Truck has 72k. Replaced the gas cap to see if this happens again.21 posts · Joined 2006. #1 · Jun 9, 2009. Hey guys. I have a Superchips tuner for my truck and my engine light has been on for a while. I just checked the diagnostic codes with my tuner yesterday and it went from code P0456 (Evap leak monitor, small (0.020) leak detected) to P0442 (Evap leak monitor medium leak detected)..
