Does it happen a little bit after you fill up gas ? If so, read on..

The most common reason for the light to come on is if the gas tank cap is not properly tightened after filling up gas. This normally happens at gas stations when an attendant fills up gas. If air gets into the tank, it will complain like this.

You should open the cap and put it back on properly. It may take almost a week after that for the light to go off.
