Where is the idle valve?

The position of the idle valve is next to the throttle: 1. The idle speed control 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 control valve acts to increase the engine speed, it will stop when the engine speed exceeds 1050 rpm. 2. This control valve is also called idle speed increasing valve in vehicles with air conditioning system. Because the engine load generated after the air conditioning compressor runs reduces the idle speed of the engine, the idle speed control valve acts accordingly to maintain the stability of the idle speed; 3. Air flow sensor, also known as air flowmeter, 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) as one of the basic signals for determining fuel injection.
