P0455 P0456 P0457 LOOSE FUEL CAP FIXED FAST & EASY 2015-2022 DODGE CHALLENGER CHARGER CHRYSLER 300 

Have you fixed it yet, if so what did you do?

Probably gotta replace the canister purge valve

@@gumrs Yep, fixed it...had to replace the ESIM on the EVAP canister...replaced it before, but new one failed also....2nd one works good so far, solved the issue :)

Question boss. If I replace the cap. Will the check engine light go away eventually? Or do I need to go to a shop to get it deleted

@@elguerrillerodefreefire5848 Check engine light wont go off by its own, it has to be deleted by diagnostic software...also issue was not the gas cap, issue was solved by replacing ESIM on the charcoal canister
