What is Code PO446 on a 2006 Ford Explorer

Question

The check engine light has come on and the OBD has given me Code PO446 but it also says EVAP System Leak.

Answer 1

P0446 Evaporative emission vent control circuit

When there is a evap leak  , you would also set a P0446,

​ Worn fuel cap where the seal is improper would cause a evap leak and set a evap code,

​ Fuel fill hose especially on a Ford tends to develop small rips and tear,
