Changan Star 2nd generation / S460 / 6363 / 6371 carbon canister vacuum solenoid valve F01R00Q021 direct-install replacement

This carbon canister vacuum solenoid valve directly replaces OEM S460-6363; universal fit. Compatible with Changan Star 2, S460, 6363, 6371 models. Its role is to control vapors from the fuel tank entering the engine for combustion, preventing fuel vapor leaks into the atmosphere. After installation, it can resolve idle instability, hard starting, or gasoline smell near the fuel tank. If you feel rough acceleration when pressing the throttle, high fuel consumption, or the engine warning light on, most likely the valve has aged and needs replacement.
