Locating the Idle Air Control Valve The IACV is usually located on the intake manifold near the back of the throttle body. Before starting the cleaning process, be sure the vehicle is not running and that the engine is cool.
What sensors control idle speed?
The computer monitors idle speed by counting ignition pulses from the ignition module in the distributor or crankshaft position sensor when the throttle position sensor or throttle switch signals the computer that the throttle is closed and the engine is at idle.
What does the idle speed control valve do?
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.

How can I tell if my idle control motor is working?
Look for a difference in idle speed. Allow the engine to run for a minute so it settles to a consistent idle, then take note of any difference in the idle RPMs versus the idle you observed earlier. If the idle has not changed at all, it’s likely because your idle control motor has not been functioning.
What to do if your idle air control goes bad?
When your idle air control valve goes bad, you will have to replace it with a new one. It is up to you if you are going to replace it with one that is the same as the original idle air control valve or replace it with a third-party brand that is compatible with your engine.
