What are the symptoms of a faulty carbon canister?
1 Answers
The symptoms of a faulty carbon canister are as follows: 1. Abnormal noises while driving: A clicking sound can be heard when the engine is running at non-idle speeds. The carbon canister purge valve produces intermittent switching actions when the throttle is opened, resulting in noise, which is normal. 2. Strong gasoline odor: If you experience hesitation during acceleration and notice a strong gasoline smell inside the car, check for any leaks in the carbon canister system's piping. Gasoline vapors may escape directly into the atmosphere through damaged areas, causing the strong odor. 3. Engine stalling or difficulty starting: If the purge valve remains constantly open, the engine's intake mixture will remain overly rich. Additionally, since the engine control unit has not yet activated the carbon canister purge valve, it will not issue a command to reduce fuel injection. This can lead to an overly rich mixture during hot engine conditions, causing stalling and difficulty restarting after the engine stalls.
