EVAP Tray Valve not Opening

After the Dyno and programming, I have been getting gas fumes in the car.
I replaced the hoses and one hose was filled with raw gas.
It's been suggested that the vent valve in the tray is not opening and that the vent valve is PCM controlled.
Is there any way to check if the tuner eliminated that function in the tune?
Or should I look elsewhere?
