How do you reset the idle air control valve on a Honda Accord?
How do you reset the IAC valve?
- Depress the accelerator pedal slightly.
- Start the engine and run for 5 seconds.
- Turn the ignition switch to the OFF position for 10 seconds.
- Restart the engine and check for proper idle operation.
Where is the idle air control valve on a Honda Accord?
You will find it at the back center of the under hood area, near the throttle body (TB) and mounted on the rear of the intake manifold (IM). You will have to remove the TB intake hose in order to gain access to area of the IM that is connected to the IACV. Remove the Honda idle air control valve.
What causes your car idling speed to be too high?
If the computerized engine control system is faulty, high idling can be one symptom. A vacuum leak in any of the hoses can be the culprit—inspect them all for leaks.
What does it mean when idle control does not increase?
If the engine idle does not increase, it means there is an issue at the idle control motor of its circuit preventing the signal from changing the idle. You can purchase a bidirectional scan tool at your local auto parts store. Make sure the wiring harness is firmly connected to the idle control motor before conducting this test.
What does accelerated idle mean on a car?
But if the accelerated idle persists even after the engine is fully warmed up, it probably indicates a genuine problem. The first step is to determine if there are any diagnostic trouble codes stored in the PCM (powertrain control module). If there are, this will give you a good starting point for troubleshooting.

Why is the idle on my air conditioner so low?
If the idle is low and inconsistent, it may be due to an issue with your idle control valve. Low idles could also be caused by vacuum leaks. 3 Look for signs of a vacuum leak.
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 happens when you idle the air control valve?
Normally, if you just start your car, the idle air control valve will cause the engine rpms to increase and slowly decrease. That would be a sign that your IAC is working.
