2016 sedan w/21k and a P0456

[johnny3fingers]

So i have a code P0456 and not sure if anyone out there can give me tips for most likely cause. I dont think this is my gas cap but going to pick one up anyway.

Rest of whats possible but wondering whats MOST likely on a low milage car.
And what is level of effort?

Possible evap hose leak
Possible evap canister
Valves/gaskets

Any useful constructive comments are appreciated.

Fuel cap first. After that continue diagnostic.

If the cap doesn’t fix it, go to a dealer or high end shop with a smoke machine. Any other diagnostic path for a small leak is futile.

Anyone know where this is located on a

Old thread, but I'm planning on replacing this on mine. Did you ever locate it?
