Code P 0456 is described as "Leak has been dectected in the evaporative system." The gas cap has been removed and reinstalled seventeen times or more over a three thousand mile period without the check engine light and code P0456 clearing.
Is there a way to prove the gas filler cap is at fault without replacing the it?
