    If you determine that the DTC is not caused by a loose fuel fill cap and an EVAP leak is detected where the vent control valve mounts to the canister, the vent control valve O-ring seal is likely the cause. Replace the vent control valve as an assembly, as the O-ring is no longer available as a separate part.
