Bad Idle Air Control Valve PO505

The car is 99 Honda Odyssey with a code PO505. The code is for the idle air control valve. I thought it was a vacuum leak but its not, what i believe is the idle valve is damaged and is allowing more air than it should. As you can see when i cover the opening in the throttle it idles just fine and smooth. This problem came after we changed the transmission so I'm not sure if I damaged it putting it back or something. I'm gonna clean it with break cleaner but don't think it will do much and then I'll post the results.
*UPDATE* Cleaning the idle air control valve did not help. It was indeed dirty but still faulty. I just replaced it and the problem is solved!

excellent presentation i thought that was my problem but found out it was my THROTTLE POSITION SENCOR.! I change it having no code and now it runs like NEW!!

[@imisspresidentreagan]

How did you know it was the throttle position sensor?

THANK YOU! I have this problem, and was thinking I might have to take it in to get a new gasket on the intake. But this might be the problem.(fingers crossed)

Thanks man appreciate the video. It just confirms my suspicion. I have a 99 acura tl with a 3.2 v6. Same issue idle is totally off. fluctuates between 1500 and 2500. i put the rag in throttle body idle is perfect again. Not going to bother to clean iac valve. online its $85. will take less then an hour to put in. Thanks again

Thanx man found the Problem m replacing tomorrow 👍👍👍 Exactly the same Problem 🤓

@thatguy3139 im not too familiar with dodge but if its 96 or newer it would most likely give you a code that indicates that it is running poorly. Idle valves have coolant lines to control the idle (i.e. cold would be a bit higher idle, warm would be smoother idle) so i have seen where low coolant or air in the coolant system causes a surging idle. Hope that helps,

It's your Fast Idle Control Valve aka FICV... Just clean that piece with carb cleaner and give it a good clean up..... it should take that problem away... Good luck

[@infinitepain951]

dude thats your throttle body, on the back is the idle air control valve

[@TheeMovieCritic88]

@6439331 These are newer models that don't have a fast idle valve. The IACV is all it has and I replaced it and problem solved.

Bien echo carnal...gracias..

[@TheeMovieCritic88]

I damaged mine by cleaning it with some cleaner. I just bought a new one, the idle air control valve.

[@arteohesdub5100]

I have the same problem with same code on Honda Odyssey 2001. Sgould I just replace the( IAC) Idle Air Control Valve? Is it easy to replace or need special tools?

[@viktor.stojic]

I have the same problem! I replaced IACV with some used one and still have the same problem. Maybie the "new" one is faulty too...

[@ZombieLincoln666]

you should try cleaning it first (actually take it off and clean the inside). It worked for me.

[@reiyen4761]

I have the same issue now. did the check engine light go away after you changed the IAC on your odyssey?

[@thatguy3139]

My dodge neon does this, is it the idle air vontrol valve?

[@eemorn]

How much did you spend? And how much do you recommend I pay a Mechanic to replace mine? '00 Civic.

[@thexflexclan]

Hey i have a question whats the normal idle on the odyssey 2001 ?

[@viktor.stojic]

I cleaned now a "new" IACV and it's better...now the rising of throttle is about 300rpm and it was 1500+. But still that's not a good engine!
