You probably have one of the following:
- loose/defective gas cap: (retighten it, clear the code and drive the car around; hopefully that's all it needs).
- leak in EVAP system: you may have a loose hose, something wrong with the canister or the vent valve is stuck open (this valve is behind the gas tank; try to tap on it gently; it may release it).
