I've got a 2007 Yaris with 200k miles. I've had a p0456 code twice over the years. Both times I OVER filled the fuel tank. Both times the code would show up the next morning. If you over-filled this could be the problem. Please check this situation first before you start tearing everything apart!! I assume there was fuel flow into the charcoal canster and the by-pass opened.
