Hey there,
So, my 2014 Summit with around 62K miles decided to light up the check engine sign yesterday, and guess what? It’s throwing the P0456 code - evap system (very small leak). The “very” in the code description adds a nice touch of reassurance, doesn’t it?
I swung by O’Reilly’s and got a generous 10-sheet printout detailing all about this code and its potential causes. Seems like the most common (and thankfully cheapest) culprit is usually the gas cap. But, here’s the kicker - I’ve got a capless tank. Anyone else dealt with this error in a similar setup?
Now, my filler neck door has always been a bit on the loose side, and I’m starting to wonder if that might be playing a part here. Looks like the surefire way to know for sure is a smoke test from a mechanic, but given the holiday season, it might take a while before I can squeeze in an appointment.Hey there,
