So I just hit 9,000 miles on my 2019 Ram 1500 and the check engine light turned on today. Took it to O'Reillys and it has code P0456 - Small Evap Leak. There's no more gas cap on the 2019s so what could cause this in a new model truck? It's frustrating getting a new generation truck with this issue so early. I will most likely take it in on Friday to the dealer since it's still under warranty. Any ideas what I can look at before Friday are greatly appreciated.
