This light comes on for emission purposes only. It could be hundreds of different things. Since you just filled up with gas, I would check the gas cap as it could be loose. If not, then you will need to get your computer scanned for codes. Your local auto parts store will likely do this for free for you.

Ok... if the gas cap was nice and tight, then you will need to get your computer scanned for codes. If you get back to me with the code number, I can point you in the right direction.
