The idle valve is in that position.

The idle speed control valve is installed on the air passage next to the throttle. When idling, the throttle valve is closed, and the airflow enters the air inlet through the idling control valve. Air flow sensor, also known as air flow meter, is one of the important sensors of EFI engine. It converts the intake air flow into an electrical signal and sends it to the electronic control unit (ECU), which is one of the basic signals to determine the fuel injection quantity. Usually located next to the throttle. When the engine idle load increases, ECU controls the idle control valve to increase the air intake, thus increasing the idle speed and preventing the engine from rotating unsteadily or stalling. When the idle load of the engine is reduced. The idle valve is located at: 1 next to the throttle, and the idle regulating valve is installed on the side vent hole of the throttle. According to the ignition signal, when the engine speed is lower than 750 rpm, even if the idle speed regulating valve responds to increase the engine speed, it will stop responding when the engine speed exceeds 1050 rpm. 2. For vehicles equipped with air conditioning system, the regulating valve is also called idle acceleration valve. After the air conditioning compressor responds, it causes the engine load and the engine idle speed drops, and the idle speed regulating valve responds accordingly to keep the idle speed stable. 3. Air flow sensor, also known as air flowmeter, is one of the most important sensors of EFI engine. It converts the intake air flow into an electrical signal and sends it to the electronic control unit (ECU), which is one of the general signals for determining fuel injection.
