check engine, no codes??

hey. recently i got a check engine light, but when i check the codes i dont get any. i know im doing it right since i get the odometer to mark dashes, and then it says DONE.

should i worry about it?? or how can i reset it to turn off the check engine light??

Some codes don't show with the self reader.
You need an external reader to show all the pending, active, and stored codes.

Same thing happened to ours. Took it to autozone. They read it. Some evap/emission code. Took off gas cap and put back on. A couple starts later it cleared.
