Hello, this will be a difficult thing for you to check without the use of a scan tool and smoke machine. Typically a loose gas cap can cause this code. if the gas is loose or left off it will trip a gross leak code. Otherwise a sticking open evaporative emissions vent valve on the charcoal cannister or damage to one the evap system lines or leak at the fuel tank could be the cause. Thats where a smoke machine comes into play by pushing smoke into the system, using a scan tool to close the vent and see if any smoke leaks out. If you see no damage you can try a new gas cap. Otherwise a shop will need to test this system.
Do you need more help with this concern?
