code PO456

[Madness hero]

Hello everyone,

About two weeks ago the check engine light came on when i checked it the code PO456 came up It says that the evaporative emission system leak detected (very small leak). What do I do to fix this? I'm still very new when it comes to cars so any help is appreciated.

NVM I discovered the problem the fuel cap wasn't completely closed.
