This bulletin applies to 2011-2012 Infiniti G25 sedan vehicles. The warning light may be on accompanied by diagnostic trouble code (DTC) P0456 (EVAP very small leak) where the DTC is not caused by a loose fuel fill cap. An EVAP leak has been detected where the vent control valve mounts to the canister. The vent control valve O-Ring seal is determined to be the cause. Replace the vent control valve as an assembly (the vent control valve O-Ring seal is no longer available as a service part).
