If you confirm that DTC P0456 (evap very small leak) is present, and the code is not caused by a loose fuel fill cap, and an evap leak has been detected where the vent control valve mounts to the canister, the vent control valve O-ring is determined to be the cause. Replace the vent control valve as an assembly, as the O-ring is no longer available as a service part.
