What are the symptoms of a damaged carbon canister solenoid valve?

[MarianaAnn]

The carbon canister solenoid valve is responsible for regulating the flow of gasoline vapor from the carbon canister into the engine for combustion, functioning essentially as a switch. The symptoms of a damaged carbon canister solenoid valve include: 1. Difficulty starting the engine, with a high likelihood of stalling. Frequent need for a second attempt to start, and the engine is prone to stalling again shortly after starting. 2. Unusual noises while driving. Specifically, a "clicking" sound can sometimes be heard when the engine is not idling. 3. Increased fuel consumption, accompanied by a strong gasoline odor inside the vehicle. 4. Erratic engine idle speed and poor acceleration. After the engine starts, the idle speed fluctuates rhythmically, and the vehicle exhibits weak acceleration.
