So i have a 2004 Hyundai tiburon gt and it was not driven for 7 months and I have a problem with the Evap. I got a check engine saying PO455 gross leak no flow. I checked my gas cap and all the lines but i think is one of the sensors but i don't know witch sensor could stop the flow in evap. So if anyone know anything let me know. Thank you
