How to Check an Idle Air Control Valve | YourMechanic Advice monly called an idle air control (IAC) valve or idle speed control (ISC) valve, this device is used on many cable operated throttle bodies to regulate the engine idle speed. This process is completed by regulating airflow through a bypass circuit around the throttle plate to increase or decrease idle speed. 3 Ways to Check an Idle Air Control Valve wikiHow The idle air control valve — also known as the "idle speed control valve" — regulates the idle speed of your engine. This is controlled by the engine's computer. Sometimes parts go bad, which results in your car idling strangely or stalling. Check to see if your idle control valve is functioning properly before attempting to replace it. Symptoms of a Bad or Failing Idle Control Valve ...

The idle air control valve is programmed to regulate and maintain the engine idle speed at a constant rate. If the valve fails or has any issues it can cause the idle speed to be thrown off. General IAC Info & Ford PWM IAC Wiring Holley Performance • IAC NOTES: Adjust the idle speed screw on throttle body, to achieve an IAC Position of about 5% at hot idle. Remember to perform another TPS Autoset, whenever you adjust the idle speed screw on the throttle body. In the Idle ICF, the "Target Idle Speed (RPM)" must be programmed to the desired RPM speed at hot idle. P0505 IAC (Idle Air Control) System Malfunction This metered air controls the idle speed. The IAC has a "plunger" or "shutter" that moves to open or close the bypass air passageway. The more air the IAC allows around the throttle plate, the higher the idle. The PCM (Powertrain Control Module) uses the IAC valve to keep the idle speed correct with varying engine demands.
