very good info it saved me money thank you so much

Thanks so much. My daughters 2003 Honda CR-V was stalling at idle. 2 mechanics looked at it and scratched their heads. One said it wasn’t throwing any codes so there was nothing he could do. How hard it is to find a mechanic that really knows their craft anymore! The other replaced the fuel pump sweating that was the issue. The idle air control valve ended up being the problem and this video was awesome for showing me what I would need to deal with and saved me a lot of trial and error. Thanks to the video creator, you gave me what I needed to fix my car after 2 auto shops gave up!

You not only showed me how to get this part unstuck but also showed me 2 other things I needed to get to in same area while giving me sizes of tools to use thus saving me from multiple project from not having all parts at once- thank you!!!

We had the same problem with a 98 Accord V6. IACV was badly clogged up and didn’t work after attempts at cleaning. Bought after market valve and found that it idled high but had to go with it as away from home. Once back the idle returned to normal and has been working ok since then. Thanks for your excellent video that was the best!!

You are a champion. My wife’s car just had this very issue, or it would idle so low it would cut out. I just followed your instructions and sure enough that spindle on the electric motor was sticking. Sure I had to go and buy the t-20 piece to unscrew those screws halfway through the job, but I was pretty happy when I put it all back together and the car runs perfectly. To anyone else about to take this on, don’t do what I did, watch the whole video first and make sure you have all the tools you need. I’m about to make a third trip and buy some coolant. 👊🏽

Had the same problem with my accord. Watched every videos related to high and low idling and still had the same problems. I was lucky to get your video and it made a difference. You saved me two weeks of headaches. Did exactly what you told to do. Thanks for sharing your expertise.

Heres a list of things Ive done to my 2004CRV that was burning a quart of oil a week, running a bit harshly and not idling perfectly.. it had 310,000km on it. I got it running alot better and its not burning oil anymore: -sea foam GDI intake cleaner, -oil cleaner additive before oil change -used “high milage” oil -put in the most expensive oil filter -lucas oil treatment for sealing the engine -gumout fuel line cleaner additive to gasoline -new spark plugs -new battery -cleaned IACV valve -cleaned the mass airflow sensor with mass airflow sensor cleaner. All of these repairs were relatively cheap and it was very satisfying to see how doing simple things can make a drastic change in the cars performance.

Great video. My car failed smog check yesterday with Amazon's china knockoff Idle air control valve for my 2003 Honda accord. Luckily I kept my OEM IACV. Followed your method and restored the function of my old OEM IACV. I didn't have a five star screw driver so I used my locking plier like a wrench to unscrew the electrical portion of IACV from the mechanical portion. In fact, I de-threaded one of the original screw that held my IACV onto the throttle body as well but I am still using the same the screw by using the same locking plier technique. (Honda dealers didn't have any screw available until next week... maybe most people de-threaded those screws because they didn't use your impact driver- hammer technique.) . Again thanks, you saved me a ton of money and time since I don't have to special order new OEM IACV now.

you saved me. I replaced a starter in my 02 CRV and thought I missed a vacuum hose. tore it all apart again and I connected everything as should. stumped, found your video, did what you did and bam! car idles showroom new! thank you!

I cleaned the IACV and it did not resolve a surging/unstable idle. After seeing your video I took apart the electric part and the rotating valve was sticky. Cleaned that and it fixed the problem. Thanks for the very helpful video.

I ended up putting a new one on but I did use this video for a reference. It helped a lot. I stripped one of the screws on the original air control. But I was able to still get it out by stuffing a rubber band in the Phillips cross

Best video on how to clean the IACV. Didn't know you could remove the electrical part, so now I can do it!

Your video and some of the comments saved me some grief. Did a starter replacement and then got the surge. Checked all over for vacuum leaks. Pulled some codes but didnt read data Pulled off idle valve, slightly stuck from carbon but i think whats happening is when the intake and throttle body are removed eg when doing a starter replacement that the tinyest but of crud grit or whatever causes the valve which is probably already carbonuzed to stick, anything entering the throttle body just drops right in to the idle valve. It took vice grips to get one of the phillips ana JIS screws loose, the torks i cut a slot with a die grinder and a sharp screwdriver broke those. Thanks honda man..

Wow I have just had the person to change the high pressure hose and still the revs very high. Car is drivable Thank you soo much, you have explained and shown everything in the short amount of time . I will ask the person to check to the IAC valve before anything else. Good work your video has saved hundreds of $. And yes having a good OB2 is very helpful in taking the guess work and trouble shooting out.

Great Video, Thank-you. My IAC valve was stuck, T-20 were rusted pretty badly, Used a fin blade hack saw to cut groove in top and unscrewed. Valve was seized up. All cleaned up, new M4-20 screws put in, now ready to test.

FixItPhillip : THANK YOU SIR FOR THIS FULLY DETAILED VIDEO HERE . BEST I SEEN YET . BEST BLESSINGS .

Your video is very descriptive, and helpful. Have 03 crv that sat for a couple of months, then had revs surging from 1100-2000rpm by itself. Cleaned as you described, and she's a goer. Thanks for your help.

I need this done to mine right now. I'm trying to decide if I'm mechanically inclined enough to not pay someone to do it. Thanks for being so detailed

Thank you very much! Using your method I was able to dislodge a chunk of intake hose rubber that was lodged in my iacv flapper. Car runs great now. Saved $100s!

Can’t wait to check this on my moms 04 crv been parked for over a year cuz it would not idle good and it would turn off

Just subscribed, your video on this was absolutely perfect... every subtle comment as you explained and demonstrated this repair was greatly appreciated. Our 2004 CR-V was purchased by our kids who have been storing it for 6 months (until the grandkids can drive) and it developed this exact problem. It has the same erratic idle and trouble code, and I have great confidence that the IAC vane is carbon-jammed as you demonstrated. Will be doing this repair once I gather replacement o-rings and the specialty tools you specified. Excellent

Idle relearn. Disconnect battery and ground negative with positive terminals for 10 minutes. Reconnect battery. Turn ignition to key on engine off for 2 seconds, then start car. Let idle for 10 minutes. Idle should drop down below 1000 rpm, after a few minutes. When that is complete the idle relearn is complete and your good to go. If the idle does not drop down below 1000 rpms, then you need to reset the computer using a scan tool.

An extremely clear well put together HD video showing the exact procedure to follow. This has been a big help, thank you.

Excellent video, just tried to do this myself, mine was rusty crusty screws did not come out, wouldnt move with anything heat everything, drilled it out to no avail, recommend picking up a rebuilt or used one, I got a used one for my manual 2004 as the throttle body isn't common, had to this process on the used one I bought. Great vid!

thank you much for this info it saved me from wasting money on a new one... but i did replaced the gasket and o-ring that was stretched out

I'm dealing with one at my shop right now ...I've cleaned the old one that didn't work. Usually it does soooo I got a new one. Same thing different code. P0505. Sooo I'm going to try one more new IAC from Honda this time. I'll keep u posted 👍

My 02 crv is having the exact same problem. Getting ready for tomorrow, im going to follow your video. Wish me luck!

Lol I just finished changing the starter and I had this issue... I forgot that one connector under the TB !! Thanks for the vid !!

*That's a badass diagnostic tool you're using. Thought my little $400 snap-on scanner was nice lol.*

You sir are a master of your trade.

Thank you. It's not often service garages don't just fire the parts cannon. Or try to tell you it's something way more expensive.

finally somebody show the right way to clean it, thanks. bro.

I just did this, fair warning, be super careful getting that small vacuum hose off. I was twisting mine and the nipple snapped. Also, the torx were impossible to get out. The head is so shallow and if there is any rust, there is no bite.

AFTER THE PROCEDURE: You will have a hunting idle problem (Consistently reving up and down in a cyclical pattern) because you let air into the coolant line right next to the IACV. Idle relearn will not fix this. Open the radiator cap, when the car is off and cold. Squeeze the radiator tube a bunch of times to burp any air bubbles out. (Who cares if you spill some out of the radiator) After that, the hunting idle should be fixed, but you’ll still have minor idle issues. Thats when you do the idle relearn process. For a noob like myself, I feel like it would have been nice to add this into the tutorial.. took me a day to figure out what was going on, I didnt realize coolant played that important of a roll.

you saved me alot of stress thanks man. I put in a k24a1 from ebay and was wondering why it was high idle. well yup that was the issue !! thanks man I was getting scared my engine swap was for no reason. much appreciated 🙏

Best video on this I've seen. 🤘

Very well executed and documented procedure. Thank you for the video!

Greetings from Seoul, Phillip. Big thanks for sharing your insights and wisdom. I bet I now know what I will be doing should that happens. Cheers.

Thanks so much, followed your advice and perfectly solved the issue!

Thanks a lot! Got the same issue on 1999 Honda HR-V, but pretty much all Hondas are the same :)

Thank you for your time and knowledge. I think im having this same probably but only randomly sometimes

I change my thermostat and housing and my crv start doing this im going to do this steps im pretty sure this is the problem thanks alot!!!

Impeccable ! La crv 2 de madame avait le même problème . Après avoir visionné ta vidéo j'ai fait le boulot et tout est revenu à la normale. Good job and thks ....

Hey Phil! Thank you! just replaced the starter motor on my cr-v, and putting the intakes back I had that very experience. Now I know what to do!

I got P0505, P1519, P1505, thinking it’s same issue on sister’s 2002 with 133k miles. What kind of diagnostic tool reader recommend for cars imports, Honda Toyota motorcycles? Especially for Non professional, imagine your a real mechanic. Run to auto zone to check codes, got a free one with apps on phone rubbish.You don’t disconnect battery? Noob, just fixed stuff cause cheap, didn’t always have enough spare loot. Thanks for making these! Excellent job.

Recently my 05 Honda Edix was running very low on rpm so I took apart the throttle body gave it a good clean up with throttle cleaner and it did fix the problem but the check engine light is still on So I am giving another crack but with this method and will see how it goes Keep you updated 😊

Your video made the job so much easier thanks very much!

Holy Smokes Capn Gung-Ho!! Props on a great video, love it, got the finesse for sure! Even left the battery connected, love the gusto!

Very much appreciate the video! Finding that 5 point star T20 is near unobtanium. Only choice is Amazon or Ebay. I even tried Pepboys but I had no idea they no longer sell parts.

Thank you for sharing your knowledge

brilliant 👍🏻 worked for me on my k24 Honda Elysion thank you

Thanks to you good thing is I found you’re video and help me a lot . Very helpful video .

thank you mate followed your instructions an fixed my idle

Nice…I think this is my issue on 2014 Honda Odyssey. Going to have to try it out.

I recommend that after cleaning and moving freely add some oil to penetrate the small bearings inside de valve, I had the same issue on mine and after 2-3 months the issue came back and the bearing oil or grease was wiped by the carb cleaner spray.

I'm #1 fans... thank for your video

Very helpful, save me money. Good job man

HEISH YOU SAVED MY TIME MAN

Youre the Man, champion mate, many thanks.

Thank you so much mate!!!!!!

Just like he says, when the 2.4L has say about 70K to 200K miles +\- and the engine sits for weeks or months, the IACV will absolutely get seized. I guarantee this procedure works to remedy the error code. - Note: The system may or may not throw an OBD code yet the idle will fluctuate.

what size is the philips screw holding the valve onto the throttle body

Thank you so much. This is very helpful 🙂, what is the type or name and model scan tool you used ?

Nice clear explanation. However, you had the throttle body out. Why not clean it too?

Thanks Ringo.

great job dude, very good information

thank you so much!! almost got new part before see your video!! save my money hehehe cheers!

You are very carefull to scribe a line on the stepper motor in order to re-assemble the same position. So why are the holes slotted? Can that be used to modify idle speed?

Perfect video. Thanks

Appreciate the details on this! Been chasing IACV code with changing out parts....and now see i need to remove lower piece to clean carbon. 🤦‍♂️ This was my only issue all along. Also, what was the scanner/test software you were using? Sweet to be able to test via the software. Thanks again!

If I don't have an ECU, is the IAC test not necessary once the valve is cleaned?

05 Honda Accord. Opposite issue…too low of idle. Installed new IAC. same problem 😮

Watching from philippines, thanks a lot

Do you think this could affect gas mileage? I don’t have any code, however sometimes idling my car idles close to the 1000 RPM, sometimes is lower (around 780-800 RPM).

What does it mean if I shifted into drive/reverse and it goes from 800-1600 RPM and kinda shakes back and forth? Also, it’s in freezing temperatures in Minneapolis.

Nice video, very helpful 👍

Having this issue with my 04 CR-V, gonna try this out and I'll reply how it goes

Where did you get your T-20 five spokes? Thank you

I recently did this to my crv but now the car won't start every light in the interment cluster lights up but the car won't even crank over if you have any idea what the problem may be please let me know. Thanks

Great video! Very detailed. What scanner did you use?

Imma be doing this tomorrow any advice for me. I don't have the special tools you used but I do believe I have that 5point drill bit you mentioned. I am going to be cleaning the throttle body butterfly and then I saw your video and decided to clean that as well since imma be so close to it. However, I didn't get a code, but my car is having this problem. It idles high when I'm not moving and it shakes bad.

Nice video sir, and good scanner What brand of scanner sir?

excellent video ,perfect

Awesome video thank you

The only torx I'm able to find are 6 point i can't seem to find any 5 point where can I get that same security bit you used?

What are those 2 screws called(connects the motor part to the mechanical part) of the iac valve? The black plastic to the aluminum portion? Thanks.

I had the same thing and did the relearn idle and checked for leaks and nothing i did almost everything that says on the internet the last thing that i did. I went to the mechanic and with a computer he reset the throttle body and relearn the idle and then it got FIXED. Everything went back to normal

What diagnostic tool / software is that? Thanks for sharing this video too!

Thanks Philip... Great video. I saw someone clean the t-body and valve without disconnecting coolant lines and without removing the electronic actuator. Would you be worried about cleaner getting in the actuator?

i am currently having this issue. 2003 honda crv 2.4 UK manufactored model. things ive tried, 1)purchased the $300 oem iac , 2) iac relearn procedure 2sec on, then 3k rev for 10 without any load, 3) removed the ecu/pcm fuse for 5 min then replace and tried the relearn again, 4) check for vacuum leaks, 5)replaced the pcv incase this was the issue. i initially removed the old iac cleaned it and installed with no luck, this is why i bought a oem replacement. One thing i’ve noticed, when i erase the p0505 code with obd scanner, the crv idles perfect until driven and the check engine light comes back on. hopefully you may have some insight. thank you in advanced

Would anyone know if the procedure can be done without cleaning the codes. Thanks

Wish you could do something to decrease that loud irritating beep from Honda dash boards.

Very good job

This video very helpful my car is accord 2004 high rpm problem what's a problem please tell me

Everything amazing my problem is that those coolant hoses are stuck, they like welded or burn to the idle valve! And I can't find the new parts(hose) to replace them ! Anyone knows the part number! Or what to do, I worry if I cut them, they will not fit right anymore.

Hello, that little vacuum hose. Is it connected to a sensor? If so, what's the name of the sensor?. Your reply is appreciated.

Thanks for the video. It has saved me a bunch of money. Does anyone know what size those t-20 screws are I need to find replacements the heads are totally rusted through.

awesome video🔥🔥

I have 2007 Civic EX. Recently experienced noise, unstable idle, and shaking when cold starts. Cleaned throttle body, EGR and MAP sensor. Replaced IAC valve. However, problem has not been fixed. Do you think if I should replace intake manifold gasket? Thanks a lot!

Nice job, thanks alot
