1. Open the hood of your Taurus.
2. Locate the throttle body. It is a round, black component with a metal cable attached to it.
3. The IAC valve is located on the side of the throttle body. It is a small, black solenoid with two wires connected to it.
Here is a more detailed description of the location of the IAC valve on a 2002 Ford Taurus:
* The IAC valve is located on the driver's side of the throttle body.
* It is positioned near the top of the throttle body, just below the throttle position sensor.
* The IAC valve has two vacuum hoses connected to it. One hose connects to the intake manifold, and the other hose connects to the throttle body.
If you are having problems with your idle speed, the IAC valve may be the cause. A dirty or faulty IAC valve can cause the engine to idle too high or too low. If you suspect that your IAC valve is not working properly, you can have it tested by a qualified mechanic.
