Why “Check Fuel Cap” Displays On?

One of the most frustrating things that can happen while driving is having a warning light come on your dashboard. And, if you're like most people, you probably have no idea what that particular light means. One such light is the "Check Fuel Cap" light. The "Check Fuel Cap" light comes on when the fuel cap is not tightened correctly or, just the opposite, is too tight. Or the fuel cap could be damaged or missing altogether. Whatever the reason, it's important to take care of this problem as soon as possible. If the fuel cap is not properly tightened, fuel can evaporate from your tank, leading to decreased fuel efficiency. In addition, if the light is ignored for too long, it could eventually lead to engine damage.
