P0441 Error on my 2016 Ram 1500

[formegolf]

Good afternoon,
Hope everyone is having a good day. I have a 2016 Ram Bighorn 1500. I just got it and it has a engine error of P0441. I replaced the Canister Purge Valve then cleared the code and in a couple of days it reappeared. I was puzzled then I read a forum about replacing the fuel cap. I replaced the fuel cap and in a couple of days it reappeared again. Is there anything else I can do? I also tried looking for the charcoal canister but was unable to find it but I think it's on top of the fuel tank? Anyway can anyone help???

Thank you, Mark

Found it interesting that the first solution was a chrysler fix, thought it could be another place to look.

The vapor canister is on the side of the fuel tank on these trucks. You may want to take a look at the ESIM switch on a scanner to see if it is switching from open to closed as vacuum builds in the tank. The switch in the ESIM is know to get stuck.
