- Hey Guys!
Welcome back to another video! In this video I will be showing you guys how to delete the Idle Air Assist Valve or IAAV for short. This is a very easy and subtle way of cleaning up the engine bay and getting rid of a few hoses near the valve cover/Throttle body area.
Let me know if you have any questions in the comments below

Thanks for the explanation on the part itself and what happens after deleting it. exactly what I came for 🙏
Thanks. Very helpful
Thank you!
Nice bro!
Thanks bro! One little thing at a time!
Does it give an error code? I read no tune is needed so there goes the other question
And do you know where I can get one ?
its that fits on CRV 2003?? Can't pass inspection
the metal tube sticking out the side of the valve cover, can that be capped off or put a little cone filter?
Yes it can
Iirc, on the tee u broke, the threaded portion is fixed on the valve so it won’t spin off bc the tee will hit the valve cover when unscrewing. So either have to break off or remove the valve cover. U did it right by breaking it by accident!
Lol never thought about it that way!! Haha
Just broke mine
Great job bro, i would put Teflon tape on it tho, being that coolant flows through there.
I was thinking of doing that, but I haven't gotten any leaks surprisingly! I checked every so often after installing it
@@dc5ronin150 you got.lucky I put. A ktuned k swapp adapter there with teflon tape and leaks one droplet of coolant .Getting so annoying went with hybrid racing adapter gonna put Honda bond it and and let it sit.
Teflon doenst really do a whole.lot
I havent gotten any leaks with teflon either. Has worked out well so far. Fingers cross tho
@@GlazeDc5that's good wish that ed case for me.
Is that a 7/8 wrench you used to remove the valve?
Naw you'll need 24mm or 15/16
Can someone PLEASE show me EXACTLY where the IACV is and what it looks like? My 2013 Si is idling like ass and i want to check/clean it but i'm not too sure where it is and if its one you can just take out and clean
It's underneath the throttle body, at least that's how it is for RSX/ep3/si
Nd since you deleted it you still have the iacv under he throttle ? Or capped
Still have the IACV
I have mine removed. I have not broke it. Also it barley spun off?? Can I brake the top off and put it back In the motor? What is the problem with that??? Also what is the size of the hex bolt? Please help 2011 Honda element
Would not recommend installing a broken one, you can remove the valve cover to install it back on without breaking. Or install a plug. Also, i do not remember the size but I'm pretty sure i stated in the video what size it was.
mine was deleted I hooked it back up and my ep3 runs way smoother if your having a problem with elevated idle this will be the place to start looking
hey was there coolant in the hole that you plugged up with the delete?
I cannot remember. Was there a lot?
There was a little coolant in mine as well. I just watched the video. Been too long since I've done this
What is that part called in 3:50?
That is called the Idle air asist valve (IAAV) and im sure you can get it from you local honda dealer or online.
What would be the benefit?… will this delete affect any other sensors??
Personal preference and cleaning tubing in the engine bay, it can affect your car's idle if your IACV if it's not working correctly.
What did you use to cover your intake where it would plug in ?
You can get just a heat shrink cap.
Dc5 Ronin can you link me one please
@@KtuluLeaderRise I don't have anything on there at the momment, but I believe you can find them at o Riley or autozone.
Dc5 Ronin Forsure I’ll go there
Dc5 Ronin last question my car has a weird idle going on like up and down. I think it’s the iacv got any opinions ? I can send you a video of what it’s doing maybe you can see it better
Do you need a tune to do this ?
Nope!
@@dc5ronin150 thanks bro
i had to remove my stock fuel rail to do this and i completed it.. but now my car isn’t starting. by chance do you know what i could have done wrong?
Make sure you have all the wires connected. Your car doesn't need this valve to run unless you have a bad IACV
@@dc5ronin150 i’ll double check the wires. could it be any issue with the fuel rail or the injectors
it was running fine before. some gas is kind of leaking out of the fuel rail also
@@jayquinox5536 definitely want to fix that gas leak
When you make the delete do any codes come up? I got a p0113 and p0102.
No CEL for me. And still no CEL
@@dc5ronin150what did u do with the other hose that snapped off the other side u broke
@@jf8322 plugged it
@@dc5ronin150 yo bro help me out I have the k24a4 and I need to know what all I need I printed two throttle body gaskets but I need to know for sure what I need with the rbc do I need adaptor for throttle body
@@jf8322 pretty sure you need an adapter for the TB. Unless you run a RBC specific throttle body. I know Hybrid racing sells them along with multiple other companies if you want to go a different route
What k20 is that
K20z1
I was really hoping you would start it at the end and show us that it doesn't run like crap...
Yeah car ran perfectly fine afterwards. Is everything okay with IACV?
My Element has a K-Series engine also.
Economic k series lol
@@icasualyt8875 actually no, it has a K24A2 swap. But, its running on a burnt exhaust valve lol.
Will this pass smog?
The IAAV only controls how the engine idles. Don't affect the emissions of the vehicle.
@@dc5ronin150 thank you! I’m just trying to figure it out if a broken IAAV is the cause of idle surging. The idle surge goes away when the car is warmed up. I replaced the IACV and still is idle surging. I’m going to see if it’s the Throttle body next.
Do you need k pro to delete ? Right ?
Nope! No need
It's a mechanical actuator btw...
i did this to my acura tsx 2006 and now its jumpy in idle
Did you fix it/have anymore info?
@@jacks_Dc5 i just put the iaav back i didnt wanna deal w anything
I just wanna know why every one is deleting this valve????😭😭😭😭😭 I’m actually trying to reinstall one on my car!
I actually snapped mine. So i figured i might as well delete it. If your IACV id working properly. You dont need the IAAV
Thanks for the video. However, I mean no offense but that is not a sensor. It is just a valve that opens when the engine coolant is under 140 degF (don't quote me on that) and closes when the temperature is above that. When it is open, it allows air to bypass the throttle body and go directly into the intake manifold which makes the engine try to run a bit lean. The engine tries to compensate by adding more fuel which raises the RPM and thus warming the engine faster (warming the engine faster is better for the catalytic converter and oil viscosity). The Idle Control Valve under the throttle body will not do this. Its purpose is only to regulate the idle RPM. Unfortunately if your Air Assist Control Valve is bad, it can stick open like mine and cause your ECU to throw a lean code.
Thank you for explaining this it’s hard to find information on this part. I’m having idle issues and I’ll check if it’s still pulling vacuum when the engine is up to temp.
its 131° so you were pretty close bro😂 my car is running STUPID lean and i think its because of this, the valve isn't creating a vacuum when it shuts and it leaks air causing my car to run 10% more lean then regular. hopefully this is genuinely the issue i cant find any info on this part either.
@@yessirskiott8778 ah yea, I hear ya on that. It may very well be causing your lean condition. You might be able to borrow/buy a scan too from AutoZone and while you're running the engine, look at the short and long term fuel trims. See if they dip lower when you plug your finger over that valve. You can probably see whether or not that valve is causing your problem this way.
I had the same thing but my problem ended up being just because I have a k-swap essentially.
I bought a 2004 honda crv and after driving it a few days I got a p0507 code, iacv I've not took it apart to clean it yet but looking around i noticed that the air assist valve was broken on both ends where the hose goes. They where flush and sealed off with something. The two hose that go to it where plugged off with bolts. Could this be my problem? My idle barely goes up and down about 100 rpm over 1k. Thanks sorry so long. Hope for a reply 👊👍
@@charliedc2A Hmm, if your air assist is cracked in those two spots, then yea it might be the cause of your high idle. It depends on if the cracks are big enough to let a lot of air in. You may have a vacuum leak somewhere else however. If you don't find any vacuum leaks anywhere, it could be a faulty idle control valve also.
