I have noticed the same thing on 00. If the light comes on, and is on for a bit, the CEL will come one. If I out gas in it, goes out, no stored codes, so, I just keep gas ini it, and dont have any probs..

Now, my 99, which I believe has a bad sending unit(fuel level), the gas light is on all the time, and it doesnt trip a CEL, so I dont knwo.

But, like I said, I havent had any ill affects. It could be another warning, telling you to get gas, because if you run your tank dry, you will more than likely burn up you r fuel pump. I dunno...
