What is a vent solenoid for Kia Sedona?

A vent solenoid in a Kia Sedona is an electronic component that controls the flow of vapor from the fuel tank to the engine's evaporative emissions system. It helps prevent fuel vapors from escaping into the atmosphere, thereby reducing emissions and improving fuel efficiency. The vent solenoid typically opens and closes in response to signals from the engine control unit (ECU), ensuring proper functioning of the vehicle's emissions system. If malfunctioning, it can trigger warning lights and may affect engine performance.
