Where is the idle air control valve on a Honda CRV?
The idle air control valve on the Honda CR-V is located on the intake manifold. It is computer-controlled, and adjusts the amount of air that enters the engine, which changes the rpm of the engine when a load is placed on it.

Where is the PCV valve on a Honda?
The PCV valve is on the passenger side of the car, above the alternator. Once the hose is removed, a 17mm deep socket can be used to unscrew it from the engine block. If it rattles when shook, its working fine, but if the ball pin is stuck it won’t rattle and should be cleaned and/or replaced.
What causes the idle air control valve to slow down?
When dirt, carbon or other debris clog the IAC valve, airflow is restricted and valve response time slows. When this happens, engine RPMs decrease drastically when you lift your foot off the accelerator and excess fuel in the engine causes backfiring in the tail pipe.

What causes a p0505 problem on a Honda CRV?
When P0505 is triggered, it is typically caused by a stuck idle air control valve, a clogged idle air control valve, or a vacuum leak. There can be other causes as well. Although, they aren’t as prevalent. This particular trouble code lets you know that there is something wrong with the idle air control system, but that’s about it.
How to clean the Idle Air Control ( IAC ) valve?
These are the cleaning steps: 1 Remove the IAC valve from the intake manifold (if it isn’t already off). 2 Remove the IAC valve gasket from the valve . IMPORTANT: It’s important to NOT re-use the gasket. 3 Spray carburetor cleaner spray into the 2 IAC valve ports and then turn the valve over to let the gummy fluid drain out.

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.

How can I tell if my air control valve is leaking?
Remove a vacuum line and connect it to a vacuum gauge to measure the level and consistency of the vacuum. You can also try spraying a soap and water mixture on the lines to look for bubbling at the point of a leak. Take note if the check engine light comes on.
What are the symptoms of a bad air control valve?
Usually, a bad or failing idle air control valve (IAC); will produce a few symptoms that can alert the driver of a potential issue: Irregular Idle Speed. So, one of the most common symptoms associated with a problematic idle air control valve (IAC) is irregular idle speed.
What happens if the idle valve goes bad?
A normal healthy idle air control valve (IAC) will provide smooth idling in your vehicle. But if the valve goes bad for any reason, the idling will go from smooth to rough. A rough idle will result in intense vibrations forming whenever your vehicle is stopped with the engine running.
What happens when the idle air control valve ( IAC ) fails?
When the idle air control valve (IAC) fails it can cause all sorts of issues; and in some cases may even render it undrivable. Usually, a bad or failing idle air control valve (IAC); will produce a few symptoms that can alert the driver of a potential issue:

When does the idle air control valve change?
When the engine is running but the vehicle is not moving, this means the engine is idling. During this time, the number of revolutions per minute (RPM) inside the engine will change. The idle air control valve is responsible for managing the engine idle speed.
Can a bad air control valve cause an engine to stall?
Sometimes the engine stalling will happen on its own while other times, increasing the load on the engine will cause it to stall. For example, if you turn on your heater or air conditioner when you have a bad idle air control valve, then your engine will probably stall immediately afterward.

Can a bad idle control valve cause stalling?
This is controlled by the engine’s computer. Sometimes parts go bad, which results in your car idling strangely or stalling. Check to see if your idle control valve is functioning properly before attempting to replace it. Look for a high engine idle. A common symptom of a faulty idle control valve can be a high idle.
Where is the fast idle valve on a Honda?
But among the zillions of Hondas that do have a fast-idle valve, the most common location for it is the front side of the intake plenum (photo 1 below). Some Hondas also have the valve mounted on the throttle housing.
How can I tell if my idle control valve is working?
To check if an idle control valve is working properly, start by turning on your engine and letting it run for a minute or 2. Then, when it’s at an idling speed, take note of the RPMs in your car. Next, turn the engine off and disconnect the idle control motor under your hood.

Why is the fast idle valve leaking air?
The engine may reach a point where it doesn’t want extra air for fast idle any longer, but the sluggish fast-idle valve is still leaking air into the manifold, increasing idle speed.
What happens when you reset the ECU on a Honda?
After you install aftermarket parts, resetting the ECU will help your car’s computer “learn” and accommodate the new parts. Sometimes a faulty check engine light may appear, so resetting the ECU can make it go away.
How do you hook up an idle air control?
Plug in the wiring harness connector. Slide the hoses back onto the idle air control, using the pliers to hold the clamps open. Allow the clamps to close onto the hoses. Reattach the tower bar and tighten the bolts firmly.
Is there an idle air control valve for a Honda CRV?
The large cargo and passenger areas in your Honda CR-V make it the perfect vacation vehicle. While you’re breathing the fresh air of the Great Outdoors, make sure your SUV is getting enough air, too with a new idle air control valve for Honda CR-V from AutoZone.
What do you do when your Honda Idles?
If you’re sure you don’t have any vacuum leaks and you’ve bled the air out of the cooling system and you still have a problem then check the IAC (Idle Air Control valve). You can do this by tapping on it with the butt of a screwdriver while the engine is running. If the idle changes or stumbles in some way you may need to replace it.
