My 2010 Dodge RAM actually has a special light just for a loose fuel cap. I
don't remember if the check engine light comes on also or not. Its nice to have
that extra indication of the exact problem without needing a scanner.
Amazon sells little bluetooth or wifi scan tools. One of those along with an
app like Torque can scan OBD-II codes cheap cheap. I think I paid $10 for mine,
its paid for itself a few times since it will also clear codes.

I'm actually only assuming Advance Auto will do this. I know Autozone
does, and it's free.
Loose gas cap can cause it, at least in gasoline cars. Not sure about a
diesel. Just realize that it may take some time for the light to go out
even if that's the problem. It take a certain amount of time with no
faults before the light goes out.
