P0456 Next Steps

Wouldn'tcha know, P0456 came back on this morning.
I'm so tired of this, haha.

So... I replaced the gas cap. I inspected and cleaned the EVAP canister and solenoid.

What's next? Do I just replace the canister, valve, and sensor?
While I was cleaning the canister over the weekend I inspected as many hoses and lines as I could and everything look okay...
Valve and sensor maybe? No idea how expensive/cheap it is.
 
I may have to try that. Was hoping this wasn't going to be a "Just start throwing money at it" problem but it looks like it might be just that...

Canister and valve is about $130-ish. Can't find the sensor aftermarket so I might have to pay $$$ from Nissan.
Were you closer, I have a parts donor I would gladly lend you to check but we're not that close so you could come, pull the parts, and experiment with your rig.
