Default Check engine light and "gas cap"

In my 06 town and country the check engine light is on and the message gas cap is displayed on the odometer. I have changed the gas cap and it didn't solve the issue. I went to advance auto parts and had them scan it and codes were all about the gas cap. I did the 3 turns of the key and got a p code on the odometer. Can't remember exactly the nbers after the letter P. Any suggestions. I need to get it fixed for e check by next month. Thanks

Probably P0442, Small or medium vacuum leak detected in EVAP system. A common fault I have encountered is a loose plastic evap tube connection to a rubber hose connector UNDERNEATH the air filter housing. NOT hard at all to remove the whole air filter housing to check it out.
