CEL low gas

[brkwd51]

today i was driving with a low tank on the way to fill it up... about 22 miles into the light and im about 400ft from the station when my CEL clicks on. i filled up and it continues to stay on... it drives fine though.

any guesses what it could be before i take it to autozone?
