Sorry! I'm not very good at English.
I have a problem, periodically turn on the lamp "check fuel cap".
What reasons can lead to the inclusion of this warning light?

the system under the hood has a small vacuum on the breather line from the gas tank. if gas tank cap is loose, or tube from tank to engine is broke, or rubber boot connectors cracked--- all will loose vacuum. ...Look at hoses and clamps on fiiler neck to gas tank
