Hey guys, I got a PO456 code for a small EVAP leak on my 2013 Grand Cherokee. I’ve already tightened the gas cap (the usual suspect), but the code’s still there. Where else should I be looking? I’ve heard this could be a pain to track down since it’s a “small leak,” but I don’t wanna just throw parts at it. Any tips for finding it fast?
