P0446 engine code

Hello,
06 Explorer EB 4.0l. 173,000. miles on it, all original. I have a P0446 engine code, (EVAP). I realize there are many possible faults, however is there anyone most common fault. Truck is running normally and no fuel smells or drop in mileage.

Check the canister vent valve solenoid resistance as well as the electrical connector and adjacent wiring for opens or excessive resistance. 50-65 ohms or so is normal.

Thanks projectSH089 for the help,

Canister vent valve solenoid was the problem, electric and connector all good.
