Check gas cap

Ok so I have an 08 gc laredo....just had the check engine light on because of a bad 02 sensor (pre cat) and had that fixed.

I filled the tank on either Sunday or Monday morning. Have taken it on a few short trips since I filled it. Went to leave work this morning and as soon as I put it into reverse I heard a little ding and saw that it read check gas cap. So when I dropped my coworker off I got out, took the gas cap off and put it back on. Light was still on the rest of the way home.

I'm reading some stuff and see that this could be just about anything to do with the EVAP system in general.

What are the odds it could actually be a bad gas cap? Can they get screwed up that fast?

And the indicator light...would that reset on its own once the problem is fixed or would you have to manually reset it?

Any help would be wonderful. Thanks.
