What will happen to the car if the solenoid valve of the carbon canister is broken?

Engine idle speed: When there is a problem with the solenoid valve or carbon canister, the idle speed of the car is lower than the normal speed. This is called idling. If the speed is low enough, the car will vibrate or even stall. If the solenoid valve or carbon canister fails completely, a vacuum leak will be formed. This will seriously affect the quality and speed of engine idling. In addition, if the solenoid valve or any hose connected to it is damaged, vacuum leakage will also occur.

Poor fuel economy: because the fuel vapor usually used in the combustion process of vehicles will be discharged into the atmosphere, the use efficiency of fuel is not high. This will lead to an increase in automobile fuel consumption, and a strong smell of gasoline will appear around the automobile or in the cab.
