What is IAC Valve and what does it do?

An IAC (Idle Air Control) valve is found on the Suzuki DF40-DF300. This valve, which is also found in all of our fuel-injected automobiles, maintains a constant idle speed by regulating the amount of air that enters the intake system. The use of an IAC enables these engines to maintain a steady and consistent idle speed.
