Welcome to the forum.

It is losing pressure in the evaporation system somewhere.
I have also seen evap codes if you over fill the tank. Pumping after the pump kicks off the first time, but usually not that code.
If you replaced the gas cap already, it is either in a hose or the canister itself usually.

 

Our R/T has been in the dealership 3 times for the "mystery engine light" and they haven't been able to fix it yet. It's not on all of the time, but it comes on and off. Usually depends on if it's been raining.
We just ignore it now.

 

If you are getting a small evap leak, the scanner can not run a small leak test. If you have an NVLD pump have it replaced.Maybe warranty.If you have the ESIM pump, replace it and the canster.Also maybe warranty.Also ck for flash updates too.
