Fuel vapour leak and P1456 code

[bwizard]

Wooow I got the problem lately....when my gas 1/4 tank left,my CEL is on, the code P1456. Blizzard let me know if what u change can fix the problem..

My 2-way valve was the problem for sure.... It clearly had a leak and since it's replacement, my CEL has stayed off and I can now hear the hissing sound when I open my fuel cap.

I thought this would fix my 1456 too, since my 2-way had smelly fuel in it…but I reset the ECU, let the car sit for awhile, then drove it and the CEL came back on yet again.

Yes, bump from the dead.
