Default P0442 on my 04 HEMI - fuel cap?

Cheers everyone,

getting the P0442 "Evaporative Emission System Leak Detected (small leak)"
Have read a lot and most of the time it seems to be a broken fuel cap?
Is that true? So I'd try and buy a new one, or is there any way to test the cap somehow?
What might be other causes for this?

Thanks in advance!

Some shops can test the cap, but, they are dirt cheap.... Take that feller off, and have a look at him. If there are any cracks in the seal, there's your culprit.

Sometimes, just taking it off, and putting it back one will fix it, if the seal is good.
