I too have had the warning on the dash indicating: "GAS CAP". It is a generic code for anything to do with the fuel cap, filler hose, or overflow, including the charcoal cannister evaporative recovery system. Sometimes it is an easy fix, to simply replace the gas cap. If people consistently twist the cap past the point where it clicks, after closing = it can wear out the cap, and prevent a good seal. However, a large majority of people have overfilled their tank too many times and the evaporative cannister is full and the overflow line is clogged or kinked. Start with the cheap solution first, gas cap. My problem started after running the extreme obstacle course at Daytona Beach Jeep Beach 2013 at which point I pulled the cannister off the bottom and had to replace it. There are no skid plates protecting it and it would be easy for sticks etc. to get jammed up in and around that cannister while even mildly off road. Crawl under and follow the filler hose down from the passenger rear of the vehicle. The charcoal cannister is approx the size of 2 loaves of bread and sits just forward of the axle, next to the drive shaft. Good luck.

A check engine light means the computer found a problem. If the light is steady on, the problem may not be too bad, like a loose gas cap. If the check engine light is blinking, that's a major issue and you need to stop driving and have it fixed or major engine damage could occur.
