Why does the carbon canister solenoid valve keep inhaling at idle?

[SophieLynn]

Carbon canister solenoid valve does not work at idle. If it keeps working now, it is recommended to check whether the solenoid valve control circuit is in the on state and whether the solenoid valve is interfered with, resulting in frequent operation. The following is a related introduction about car idling: 1. The role of car idling: Idling is a working condition of the car, which means that the engine is running in neutral. The speed of the engine at idle is called the idle speed. The idle speed can be adjusted by adjusting the size of the throttle and so on. Idling means the engine "outputs power but does no work". When the engine is running, if the accelerator pedal is completely released, the engine is in an idle state. 2. Reasons for unstable idle speed: Direct reasons refer to mechanical parts being dirty, worn, or installed incorrectly, resulting in changes in cylinder power, which in turn causes an imbalance in the power of each cylinder, leading to unstable engine idle speed; Indirect reasons refer to the abnormal operation of the engine electronic control system, resulting in poor combustion of the mixture, making it difficult to balance the power of each cylinder, causing unstable engine idle speed.
