What is the IAC valve?
The IAC valve is a component of the fuel system in a vehicle. It is responsible for regulating the flow of fuel to the engine, and is located between the fuel pump and the engine. The IAC valve is controlled by the engine control unit (ECU), and is used to adjust the fuel delivery to the engine based on different conditions.
The IAC valve is opened and closed by an electric motor, and the position of the valve is monitored by the ECU. The ECU uses the IAC valve to control the amount of fuel that is delivered to the engine. The IAC valve is used to regulate the idle speed of the engine, and to prevent the engine from stalling when the vehicle is stopped.
The IAC valve is prone to faults, and when this happens, it can cause the engine to stall or run rough. If the IAC valve is not working correctly, it is important to have it diagnosed and repaired as soon as possible.
