17 Mustang GT E85 Code P0456

[imunoz19]

Good afternoon,

Wanted to see what you guys think it might be for the code P0456
Is the E85 causing damage to the EVAP system?
I been running E85 consistently for a year now

Thanks

Doubt it's e85 related. A smoke test will find a leak and/or help find a blockage.
Check the fuel filler is sealing. And if you top off the tank when filling up then stop that practice.
