CAR IDLE AIR CONTROL VALVE WORKING

The primary function of the car idle air control valve (IAC) is to regulate the engine’s idle speed by controlling the amount of air that bypasses the throttle plate. When the engine is running at idle, the throttle plate is typically closed, restricting the airflow into the engine. 

However, a certain amount of air is necessary for the engine to continue running smoothly at idle. The car idle air control valve IAC comes into play here, allowing the engine control unit (ECU) or car computers to adjust the amount of air entering the engine without altering the throttle position. Besides, here are the signs of bad engine control module.

Here’s how it functions:

• ●The IAC car idle air control valve responds to signals from the ECU, which constantly monitors various engine parameters, such as engine temperature, load, and air intake. 
• ●These inputs help calculate the required amount of air needed for stable idling.
• ●The movable pintle or valve opens and closes an auxiliary air passage, allowing air to bypass the closed throttle plate and mix with the fuel in the intake manifold. 
• ●By adjusting the pintle’s position, the IAC can fine-tune the amount of bypassed air and, consequently, the engine’s idle speed.
• ●The IAC car idle air control valve compensates for the electric load fluctuations by adjusting the idle speed, ensuring the engine remains stable and doesn’t stall. 
• ●During cold starts, the IAC car idle air control valve provides additional air to support the enriched air-fuel mixture until the engine warms up.

FAQs

1. What is an Car Idle Air Control Valve and what is its function in the car?

The car idle air control valve (IAC or IACV) also called idle speed control (ISC) or stepper motor is used on fuel injected engines to control idle speed. The stepper motor type of IAC features a pintle, which is used to either block or open throttle air passages. The powertrain control module (PCM) controls stepper motor operation.

2. Which are the symptoms of a broken car idle air control valve/Stepper Motor?

Not surprisingly, a broken IAC car idle air control valve often results in engine idle problems. An engine that is idling too fast or too slow may point to a faulty IAC. An engine that stalls out may indicate IAC car idle air control valve problems as well.

3. How can I check, if my car idle air control valve/Stepper Motor is broken?

Typically, if there is a problem with the IAC car idle air control valve or its control circuit, the PCM will set a diagnostic trouble code (DTC) and turn on the check engine light (CEL). If the light is on, you can plug a diagnostic scan tool into the diagnostic port under the dash and read the stored trouble codes. If the codes indicate a problem with the IAC car idle air control valve or its circuit, a vehicle specific repair manual should be consulted for further testing.
