How to Determine if the Charcoal Canister is Damaged?

[LeReagan]

Methods to determine if the charcoal canister is damaged are as follows: 1. Remove the charcoal canister solenoid valve and blow air into the intake port with your mouth. If air does not pass through, the charcoal canister is not damaged. If air passes through, it indicates the charcoal canister is leaking and damaged. 2. While driving, there may be abnormal noises. If the engine speed is above 800 RPM and you hear a clicking sound, listen carefully to determine if the clicking is coming from the charcoal canister solenoid valve. If it is, there is no need to worry as it is a normal phenomenon. 3. If the car jerks when accelerating and the gasoline smell inside the car becomes stronger, check if the piping of the charcoal canister solenoid valve has cracked. 4. If the engine idle speed fluctuates regularly and the car struggles to accelerate, check if the air inlet and filter screen of the charcoal canister are clogged. 5. If the engine is difficult to start or suddenly stalls after being started with difficulty, it could also be due to a malfunction of the charcoal canister solenoid valve.
