Symptoms of a faulty canister purge solenoid valve: 1. Abnormal noises while driving, specifically a "clicking" sound heard when the engine is not idling; 2. Increased fuel consumption with a noticeable gasoline odor inside the car; 3. Difficulty starting the engine, frequent stalling, often requiring a second attempt to start, and the engine easily dying again after starting; 4. Erratic engine idling and poor acceleration. The canister purge solenoid valve is a device installed in cars or motorcycles to reduce air pollution caused by fuel vapor emissions while improving fuel efficiency. Method to determine if the canister purge solenoid valve is faulty: After disconnecting the hose from the canister purge solenoid valve, wait for the solenoid valve to activate, then partially block the valve with your hand. If you can feel the solenoid valve continuously sucking air or not reacting at all, it indicates the solenoid valve is damaged.
