Yes, if you cap is not tight it will through a code. retighten the cap and the light should go off if not, get the code read (not erased) and go back to them with it.

It will set a code for the evap system. Just leave it alnoe, it will automatically turned off and ereased.

Your gas cap probably says "Tighten past 3 clicks." This is exactly why.
