Code P0442: Evaporative Emission System Leak Detected (small leak) One common cause for this can be a loose or poorly sealing gas cap. Also there is supposed to be a soft rubber o-ring type gasket on the gas cap, that seals against the filler neck. If it is missing or damaged it may leak. Old, dried, and cracked rubber hoses anywhere in the system may also account for the leak.
