Question Check engine light is on, but no codes?

I have a 2006 PT cruiser with 49,000 miles on it and just today the check engine light came on. I checked the gas cap and it was fine. I did the 3 key turn and it came up saying "done." My question is could this be something bigger or does this mean it might go away because it has no code to show?

The car itself is running fine, no overheating, no rough idle, or anything else noticeable to the untrained car eye.

If anyone might have any ideas on what the problem could be or what the next step for me is? Should I take it in or should I wait a little bit? It said in the manual to wait for at least a few times of driving it and it might fix itself?

Should I possibly go and buy a new gas cap?

Anyways thanks for your time. I am a new PT Cruiser owner and love it, just not real good with cars. Thanks.

just a thought :|, why dont you disconect the battery for 10 min and let the system reset. if the check engine light came up again then try other resolutions, there is a chance that you didnt close the gas cap all the way when you last filled it up with gas (check engine light wont come off until it is reseted)

as it happened to me twice while my car was under warrenty, took it to the dealer. first time, the dealer said it is fine and nothing wrong with it. 2nd time he said it is fine and decided to replace the gas cap!!
