What Happens When a Car's Charcoal Canister Solenoid Valve Fails?

[AugustDella]

A malfunctioning charcoal canister solenoid valve in a car not only increases fuel consumption but also affects the normal operation of the engine. If the solenoid valve remains closed, gasoline vapor inside the canister will accumulate and eventually overflow, leading to waste and environmental pollution. Method to determine if the charcoal canister solenoid valve is damaged: Since the solenoid valve operates intermittently, after disconnecting the hose from the valve, wait for it to activate and partially block the valve with your hand. If you feel the valve continuously sucking air or not responding at all, this indicates a faulty solenoid valve. A properly functioning solenoid valve should intermittently suck air. If it doesn't, the valve is likely damaged and should be replaced.
