The idle air control valve (IAC) is a key component of many electronic fuel-injected engines. It controls the amount of air that enters the engine, closing the throttle body to stabilize idle speed. Over time, the valve can become faulty due to carbon buildup, and the electronics that operate it can also malfunction. If your IAC valve fails to function correctly, you might experience a hard start, rough idle, or stumbling on takeoff.
If you notice a warning light on your dash or instrument panel, you need to replace the IAC. This part of your vehicle can cost between $70 and $600, depending on the current market price of the components. It is worth it to learn more about how to repair your IAC if you have a knack for mechanics. The cost of replacing it is around $110, and you can complete the task yourself, if you’re confident in your mechanical skills.
The IAC valve needs to be cleaned every so often to maintain its optimal performance. To clean the valve, first turn off the engine and disconnect any electrical wiring that might be involved. Then, clean the IAC valve with brake cleaner. You can also try applying a little voltage to the motor/solenoid to see if the valve functions properly. Finally, clean the throttle body mating surface to remove any debris.

Where is an Idle Control Valve Located?
If you own a Ford F150, chances are you’ve run into problems with your idle control valve. In the past, the idle control valve was relatively easy to replace. The problem usually manifested itself when your vehicle’s idling speed wasn’t as good as it should be. To fix it, you should visit a Ford dealership or mechanic for assistance.
If you’ve ever experienced misfires, you may need to replace the idle air control valve. This valve regulates the engine’s idle speed, and it counteracts extra load on the engine when the vehicle is cold. If this valve is failing, it’s most likely because of excessive carbon buildup in the intake manifold. To clean this valve, first remove the wiring harness. Then, remove the idle air control valve by loosening it with a socket wrench.
The IAC valve is located on the driver’s side of the throttle body and can be easily identified by its large black color. It has two bolts that you can remove with a wrench. Using a clean shop towel, clean the throttle mounting surface and the mating ports. Then, install a new valve with a new gasket. The Idle Control Valve on a Ford F150 is located on the driver’s side of the throttle body.
How Do You Reset the IAC on a Ford F150?
In order to reset the IAC on a Ford f150, first remove the battery negative terminal (10mm wrench). Then, hold the ignition key in the START position for 10 to 15 seconds. Once you’ve done this, the truck should start. It may take between two to four minutes before the computer returns to normal operation. After doing this, the computer will have to be retuned and reset after 12 starts and 48 miles. If the truck still does not start, you may have to do this process again after 40 full cold starts.
If you notice that your idle isn’t as smooth as it once was, it’s likely your idle air control valve is the culprit. A malfunctioning IAC valve can cause erratic idling, a lack of power, and frequent stalling. However, this problem is easy to resolve and can be fixed for very little money. In addition, you can use this guide to troubleshoot any IAC issues with your truck.
How Do You Clean a Ford IAC Valve?
Learn how to clean your IAC valve with these simple instructions. After cleaning your valve, the next step is to reinstall it.
