P0446 MEANS RESTRICTED/BLOCKED EVAP VENT PATH, UNDER THE TRUCK THERE IS A EVAP VENT SOLENOID SOMEWHERE NEXT TO THE GAS TANK, IT HAS A PIPE GOING FROM THE EVAP CANISTER AND ANOTHER TO A SMALL FILTER, CHECK THAT FILTER TO MAKE SURE IT NOT PLUGED WITH MUD OR SOMETHING ELSE.

P 0446 is EVAP System Vent Control System. This points to an electrical problem. Solenoid, connectors , or wiring.

Sorry control circuit is what it should say. Still an electrical problem.
