Ford Escape Idle Air Intake Control Valve

• Motorcraft New
• The IAC helps regulate the amount of air that enters the engine at idle. If the computer senses that the IAC isn't doing its job, a trouble code will be stored and the Check Engine light will illuminate. Using the proper scan tool, the trouble code can be "downloaded" and then deciphered by the scanner's instruction manual or by consulting a comprehensive service manual for your vehicle. If the code indicates an IAC problem, the fix is usually straightforward, as the Steps in the photo gallery show. You can often adjust and even replace the IAC in less time than it takes to drop off and pick up the vehicle at a service station.
