engine has code p1457 evap system leak detected

anyone know if this is expensive to fix, and im assuming its just affecting my emissions and is no problem to drive

doesn't seem like anyone reallys knows just ask a car shop professional or any car professional who works on repairing cars they should easily tell you what that means. not many people are able to recieve trouble codes on their own unless you buy youre own trouble code scanner just look into it
