What is the general lifespan of a car's carbon canister solenoid valve?

[DiChase]

Carbon canister solenoid valve lifespan is generally measured by the number of switching cycles. Pilot-operated directional valves last approximately 30 million cycles, while direct-acting types last about 5 million cycles. The carbon canister solenoid valve is a device installed in vehicles to reduce air pollution caused by fuel vapor emissions while simultaneously improving fuel efficiency. Additional information: Installation location of carbon canister: The carbon canister is typically installed between the fuel tank and the engine. Since gasoline is a volatile liquid, fuel tanks often contain vapor at normal temperatures. The fuel evaporation emission control system functions to direct these vapors into combustion and prevent their release into the atmosphere. Methods to determine carbon canister solenoid valve failure: When the hose on the activated carbon canister solenoid valve is disconnected, wait for the solenoid valve to operate, then partially block the valve with your hand. If you can feel the solenoid valve continuously drawing air or showing no reaction (not drawing air), this indicates valve damage.
