What are the symptoms of a faulty carbon canister?

[DeJanelle]

When the carbon canister in a car is faulty, the following symptoms may appear: 1. Weak acceleration: If the car experiences unstable idling or weak acceleration, it is usually due to a clogged air filter screen in the carbon canister. In this case, the filter screen should be cleaned or replaced if necessary. 2. Abnormal noises while driving: If the vehicle makes a "clicking" sound while driving, it may be caused by an abnormal electromagnetic valve switch in the carbon canister. This situation requires repair or replacement of the component. 3. Fuel leakage in the pipeline: If there is a strong smell of fuel while driving, it may indicate damage to the fuel system of the carbon canister, causing gasoline vapor to be directly released into the atmosphere. 4. Difficulty starting the engine: A damaged electromagnetic valve in the carbon canister can also lead to abnormal concentration of the internal gas mixture, resulting in difficulty starting the car engine.
