I would be highly suspicious of a loose gas cap or a poor seal at the gas cap. 1996 or newer cars have a self test that will illuminate the light if there is a leak in the fuel evaporative system. The EPA doesn't want gasoline to evaporate and be exposes to the outdoor air as it release hydrocarbons by doing so. Since the light came on when you filled the tank, it would lead me to think the cap is the cause, although there are many other reasons for a check engine light to illuminate that may be different from this. Answer

Make sure you twist the gas cap so that it clicks several times after getting gas. You may also do it after the light comes on to see if that doesn't solve the problem.
