The codes are P0455 & P0442 EVAP Control Systems Leak Detected (small leak) (gross leak) so what is causing the problem? It's not the gas cap already replaced the old one with a new one from the dealership. I'm thinking charcoal canister. Could you please help me figure this out? FYI It's a 6 cylinder

You have a leak in the EVAP system. I recommend having the system smoked. That is a process in which the system is slightly pressurized (1psi) with smoke, The smoke will leak out where the problem is located. Then you will know what to repair.
