What is the code number when the gas cap is loose? Gas cap is not on the list.

I have been getting P0442 for years now. Changed the gas cap twice, but my leak is somewhere else.

I did not check the codes but I did have the check engine light on last fall. I arbitrarily changed the gas cap figuring a possible $15.00 fix was worth it compared to the dealer charging a $90.00 "diagnostic fee" before trying to repair anything. Got lucky, I turned off the light and it stayed off !
