This man is what we would call a “TC Technician”. It is the highest level there is. Having at least 20 years of experience. It’s always a pleasure to watch a TC Technician work. Absolutely brilliant and 100% competent in anything he does. Thank you.

Man you don't know how much I've searched on this topic...but I haven't found any good video...finally yours one helped me...thanks a lot!

I did this on my 93 Camry le 2.2 due to a strong vibration while in drive or reverse, not neutral. Engine turns over much quicker now, drives smoother, and the idle vibration is no longer ridiculous. Thanks so much

This is without a doubt the best video on cleaning the IAC valve. Thank You.

You, sir, are a GODSEND! Very clear and concise instructions. I'm NOT a mechanic; and, I'm petrified at the thought of disassembling multiple parts on my car's engine, to accomplish a task. You saved me from that nightmare. And, I believe I will never forget you, because of your singular kindness, of producing this particular video. It's given me the courage to tackle a vexing problem, that, I did not have the understanding to explain; the way my car seem to be running less efficiently over time. I was getting dismissive responses from mechanics, suggesting that because my car was old ('95 Toyota Camry), I should be resolved to ACCEPT, that, my car should NOT be expected to run well again. Thank you for giving me hope, to remain in a car that I am happy to own.

This was a brilliant and very timely video for me. On my way home one night this week I discovered that my rpm was fluctuating between 1500 & 2500 every second. I had an important commercial inspection job the next morning and my '02 Toyota Highlander was filled with equipment I did not want to have to load into a rental. I found your video and got up the next morning at 5am, followed your instructions and got to work on time! But, wait -there's more! I have put 170,000 out of the 225,000 miles on this SUV and I have NEVER had this kind of MPG before. Two months earlier I noticed my MPG had dropped to 18.6 -I am now averaging 21.5 after only my first tank of gas since the IAC valve cleaning. I believe the valve has been sticking for years. When I started the ignition on the morning of the repair the idle was stuck at 3,000 rpm. This is the single most important and satisfying repair I have EVER made on ANY vehicle and I have you to thank for it. Thank you for taking the time to share your knowledge and for doing it so clearly -YOU ARE THE MAN!!

Thank you spent hours to day doing spark plugs ,leads ,fuel filter to fix my low idle and stalling. Your method took 5 minutes and job done

This is one of the best explanations for part of the air intake that almost nobody has gone so deep ever before , thank u so much sir !

Thanks for the tips and clear instructions, I followed them and cleaned everything up and my 2000 V6 Camry now runs sweet, thank you.

Figured there was a problem when the engine was stalling in the mornings when the engine was cold and I came to a stop. One morning the engine stalled and I couldn't get it restarted. Did a simple RU-vid search on "'99 Camry Engine Stall Problem" and watched a video that talked about the same thing as this video but didn't remove the drain hose. This one came up next on autoplay and was more detailed. I removed the hose and worked in the carburetor cleaner as suggested (actually used throttle body cleaner). I didn't completely remove the throttle body as he did in detail but I did remove the drain hose underneath. Worked in the throttle body cleaner for about 5 minutes and drained the cleaner. Whole process took about 2 hours from start to finish and it worked like a charm on a $4 investment on the cleaner. Thanks for the tutorial!

the best explanation on how to clean the idle air control valve... thanks you just saved me a lot of money.... thanks again

After a year of trying to figure out what was wrong with my 97 camry (taking it to shops, replacing filters, full tune up, etc) this was finally my answer, Thank you so much for this video. It was very detailed on how this part works and how to clean it properly. 1000 thank you's for finally showing me how to fix my car.

great stuff ..properly explained and relatively straight forward , as long as you dont get your hoses and screws mixed up.....or round any screws and nuts... this is a job for a nice sunny day ...all relaxed ..thank you. also well mentioned the fact that some people are just spraying throttle and carb cleaner into their pistons and engine.....which is not a good move..

I must say, this actually is the better method. I wish every repair video explained so clearly the mechanics behind why the repair works as well as you do. Thanks for this! I am doing this today on my V6!

Thanks, I fixed my car this weekend! It was idling as high as 1700 rpm and now it goes as low as 800 rpm

Rarely do you see a video that comes all together, video ,audio, content. You nailed it.

I was getting ready to remove and clean my IAC on my 2001 Camry V6 and I stumbled on to your video. So glad I did! I will absolutely try this method first. Excellent discovery and a great job explaining how the IAC operates. Well done sir and thanks.

Worked great, never had carbi cleaner so I used WD40, worked like a charm, you need a medal :)

Thanks for this! My first attempt at cleaning my throttle body and IACV on my 96 Honda Civic EX A/T didn't fix my high fast idle problem but gave more acceleration. Either I didn't clean it well enough because I didn't remove the coils and rotate the magnet back and forth fully, or I need to loosen the two screws and rotate the plate a bit CW to get the valve to close further at startup temp (the one calibrated at factory). One way or another, your video serves as a pep talk to ultimate success hopefully.

A must see video for anyone wanting to learn in depth operation of how the throttle and IAC works. I enjoyed the video. Thank you!

My 2001 camry was running ar 1800 rpm when warm. Cut the a/c on and it will drop to 1400 rpm. Cleaned the throttle body. Same results. Watched your video. Cleaned the icv and magic appeared. Runs like new now. Thank you. Saved me alot of money. Thanks

Thank you. Just fixed my son's 2001 Camry using this video. My idle air control does not have that down tube but exercising the actuator with the intake full of carb cleaner worked a charm.

Excellent video. When I change my fuel filter, I also plan to clean my throttle body and with this video, I can now clean the IAC valve. A few years ago I brought my car to the shop for idle problems and it cost about $75. Now I can do it myself for the price of 1/4 can of throttle body cleaner or about $1.50. Thanks

Finally, a video that makes sense & clearly explains things. I'm glad I kept searching. He's right, money"s tight, & good night.

This method absolutely works on a 1995 Camry as well. Thank you so much Zero!

2000 Avalon. Banging my head against everything trying to figure out the problem. The car would not start unless I held the accelerator pedal down and then it would die when the pedal was released. Wondering about fuel issues. This did the trick (so far, as I haven't driven it yet). It has started right up three times and idles as it should. Thank you very much for posting this video. There should be a knighthood in it for you!

Thanks for sharing the post-iac valve removal wisdom...made the process quick and simple. Sienna now starts like a champ!

Very nice. I really appreciate not having to remove the throttle body (although I've already got it off in my garage). Flooding that little chamber by plugging that pipe is genius! I got to the point of removing those 4 screws on the throttle body to crack it apart so I could clean those little chambers, like you did later in the video, but I could not for the life of me get those screws to turn...stripped like they were made out of lead. Sooo, I'm so happy I can clean that little valve without taking it apart...you just made my day. Thanks!

Well done, Sir. Excellent marks in presentation, description and instruction. I look forward to more Toyota repair videos made by you.

I've loved my 98 and 99. Both have experienced issues with the IAC, resulting in having to 2-foot the pedals to keep it alive. Going to try this trick to get it resolved!

Followed your instructions for cleaning the IAC but only turned the valve controller back and forth for about a minute using throttle body cleaner instead of carb cleaner. You don't need to remove all the stuff you did to get this job done though. I only needed to loosen the backside clamp that connects the throttle body to the plastic intake tube from the air box and wiggle it to the side just enough ... then I unfastened the electrical plug to the IAC. Then I performed the cleaning like you have shown. This seemed to do the trick and my idle is much smoother especially when the A/C is on. Thanks for the tutorial ... the whole cleaning took me only 15 minutes from start to finish.

Hi! This is very helpful, I and my dad are having problems to fix a 2010 toyota camry, the engine will start for a while and then dies immediately. Now we know what to do this is very detailed instructions and tips. thank you so much!

Excellent contribution to the RU-vid community! Thank you for taking the time to put this video together and share with us!

Beautifully described the procedure of cleaning throttle body without removing from the car...excellent video with great information and tips.....

my 1998 Toyota Camry has this issue: sometimes very lower idle speed during starting the engine, the engine would stop if I release the gas panel. this happens sometimes, not very time. It happened 3 years ago, I had it serviced and worked well. now it starts to show the problem again. I went to car repair store and they would charge me $179 for the cleanup. that is quite expensive, so this time I will give it a try. Thanks for your video, this helps quite a lot! I will do it this weekend.

Have been going crazy with this issue, now fixed. Great video and many thanks!

I also have a 97 Camry that has a similar problem: Engine stalls immediately when cold starting. It happened 3 times before and the dealers always charged me about $400 to replace IAC. I happens again now, but I refuse to take it to a dealer immediately. Instead, I searched the internet and realized that it seems to be a "unique" issue with Camry. Few websites suggest cleaning the IAC and show how to do it. But I found this Zero Garage to be the best: It not only tells you how to do it, it also explains clearly why.I did not flood the IAC as suggested. I just spread the cleaner few times while continuously turning the gate axis to loosing the gunk. It seems to work because now my problem is solved for $5.00! Thank you very much for doing such a great job educating me! By the way, I am not handy with cars. This was actually the first "major" repair of a car that I ever did. I feel great because I accomplished a $400 repair job!

Very informative! My 1997 Toyota Ipsum had the same problem, lucky I watched your video prior to cleaning my IAC valve which is exactly the same as yours. It saved me so much hassle for the job. My car is back to normal, thanks!

Great job, thanks! I've done this before on other vehicles and I see the Toyota nuances to expect!

This worked great on our 2.2 95 Camry. Simple repair by cleaning the ACV, it was stuck, now have a very happy daughter who doesn't have her steering wheel shake like crazy in reverse!

Thank your Video Uncle, It is pretty clear for me about the symptoms, Functioning and how to deal with it.

Great video. I've seen them spray into the opening and wondered where it would go....Now I see a better solution! much thanks. My 2000 camry is not throwing a code for IAC..just a rough idle intermittent when sits after warmed up.

Great video, man. I was about to spend money on new sensors and you saved me a kings ransom. You rock, also your other videos are great. Let me know when you build a time machine or particle accelerator

my car is 1995 camry. 184,678 milage. its running fine. ill remember this tip. you did a great explaining and demonstrating what you had to do. i liked your music.

what a relief. My little toyota starlets been idling high for ages... after i left it off the road for a year. Tried this method and it's back to normal! - the little twisty bit was almost solid... bit of fluid and a twist around and its sooooo much looser. I owe you! thanks a lot

For followers, his alternative method that "doesn't require you to remove it" is to "plug the large middle hose with your finger" while it's still on, that he describes at 4:00 then flood with carburetor cleaner.

I did this yesterday on my 2000 Lexus ES300, worked like a charm. Took about 40 minutes. I used to just spray the little opening and would have to take it apart every couple of months because the engine would struggle or stall while idling. Saved me hundreds of dollars!

Excellent, my 2006 Avensis is doing exactly what you outlined.

I just finished fixing a fast idle and P0505 error in my nephew's camry thanks to your video. Not knowing better, just from first inspection it appeared that the IAC simply controls that vacuum dashpot right next to it, using that to regulate idle speed. Your video corrected my misunderstanding and clearly explained exactly how it worked. Thanks!

When cleaning valve on the car, spray cleaner into the gap behind the throttle plate; use sparingly because too much cleaner flushes the gunk and carbon into the rear bearing of the IACV causing valve to stick (I did it once on my 87 Camry, so I had to get a used one from the junk yard.

Oh my lord Jesus finally a video that thoroughly explained how to simply clean this because I cleaned my throttle body and some of the carb got into the iac hole and my idle has been stuck at 1000+ but finally you have a good guide without taking off the throttle body

This was the best video on cleaning this valve. The others never said anything about it running down the center tube and likely why I could never do an effective job.

Thanks for the video. A mechanic quoted me $550 to replace the throttle body of my 2004 camry. Went and bought a throttle cleaner and fixed the problem, but aafter watching your video, l am keen to have a look at the control valve and see what's going on in there cos the start up is still a little bit rough. Subscribed!

super helpful u helped me not worry about CA smog/emissions test and not dread buying a newer or new car or be robbed by a mechanic/stealership

love videos when narrator gives explanations. good clear voice and pace of your speaking that helps. thanks

Thank you for taking the time to thoroughly explain what the issue was and how to simply solve it. This video was a great help.

I sprayed a little sea foam and now it stays on when cold but today I will take the house off the bottom and then try that because its idles super low. No power drives like the fuel filter has never been replaced. Thanks for the good information!

Enormously helpful!! I really appreciate the detail. I would not have guessed that plunger rotated magnetically. I will use this today. Thank you!!

ok. My car is a Camry 2000 and do not have that coil nor cable. I Just exposed the hole inside that metal tube, sprayed 1/4 Mass air flow sensor cleaner. When I tried to started​ the car, suddenly it doesn't started! But in the fourth attempt, it worked! It is better now. The car is working at lower revolutions and vibrations where reduced! Thanks a lot!

It isn't harmful to use the carb cleaner in the IAC port in the TB opening. It evaporates rather quickly when used in short bursts. It also saves time from removing the IAC and hoses.

Any info on Camry regarding the vacuum system and repair, and or fuel system would be awesome, you sir are a teacher....i tackled the crank and camshaft seals, oil pump seals, water pump, timing belt and timing, throttle body cleaning, egr testing all from youtube and DIY guides...when i do these things feel a sense of accomplishment that's great and i urge more people to learn and take charge off life's hurdles...you can win sometimes. 39 and always learning!

My 94 Celica has the same engine and basic setup here, and this helped me a lot. Thanks for the video.

Absolutely Terrific video! Thanks to you I was able to successfully clean out the IAC valve with this nice method. You are very thorough with clear explanations and it's much appreciated. If you ever replace or adjust the throttle position sensor or how to tighten the throttle cable please do a video.

What a great video! Thanks very much! I have an 06 Corolla I am preparing to do this on, and I wasn't looking forward to tearing the whole throttle body off. I have just subscribed and liked. Thanks again for the on car cleaning method. Have been systematically cleaning everything bit by bit.

👍🔧👍🔧👍🔧 Thanks for showing us what the valve looks like and how it works. I could be wrong, but I think the screws are JIS not Philips. I ruined one of the screws trying to break it loose. Just in case anybody ends up in the same situation- I attempted to use an extractor to get the screw out. The extractor broke. I was going to try again but the drill bit broke. I ended up using my Dremel to cut an ugly and uneven slot in the screw. Using a flat head screw driver, the screw turned easily as if it wasn't even tight.

A great video, thank you so much! Been an engineer a long time, so I like to understand how the system works rather than just blindly follow a procedure. Thank you for explaining how it all works! I have an idle speed issue with my 2000 Camry LE (4 cyl 5S-FE engine) where the idle drops below 500 RPM and the engine stalls. But this only happens after the engine warms up. So I still need to dig into how the IAC works and see if not enough idle air is the root problem, or a symptom of something else, like bad vacuum or sensor. But you're video helped me tremendously, thank you!

Wish all repair videos was like this one :D Thanks a lot. I have a 1998 Camry that has never had any problems with the IDLE control, but I think I will clean it soon anyways just to be nice to my car :D

This is a great video, thanks so much for posting it! It really helped clean out my IACV on my Toyota Camry 2001 and fixed the stalling on start-up problem.

the screw heads are NOT PHILLIPS.. they are POZIDRIVE.. or ISO.. since ISO screw drivers are impossible to find.. use a pozidrive.. the bits will be marked PZ1 , PZ2, or PZ3 using a Phillips screw driver in a pozidrive may result in a cross section tear out.. pozidrive have a dot next to the cross. (+.) ps... this way of cleaning the idle air control valve works.. i normally spend the extra time and remove the entire throttle body.. after picking up a throttle body mounting gasket and an idle air control valve mounting gasket. i remove the idle air control valve and the coil winding from the end ... this allows me to really get it clean with the carb or brake cleaner.. please for those who go this way. do not remove the far end of the idle air control valve.. only the electric section.. you don't want to change the spring tension..

Well, Ive just finished done this to my mother 94 Corolla (4afe engine). Let me tell you it worked great, it really does. This is the beauty of internet, where you can share crazy and usefull tips for almost everything you need. Great video once again man, take care

Got to respect a guy with like his, I can tweel that he stays busy all the time and don't worry about getting his dirty. That , my friends is a man that can fix your car and make it run right.

I did exactly what you did on my '98 Camry LE 4cyl. IT WORKED. You saved me a LOT of money! THANK YOU!!!! THANK YOU!!!!!

For my needs, the best part of this video was learning that the valve was suppose to turn. Mine was stuck at first. I have a 2000 toyota camry Le 2.2. I could not find a drain hose on mine. The valve turns freely now but for about 3 seconds it seems to stick closed on the first cold start, I don't know if It need more cleaning or a new valve. Excellent teacher and video. thanks

Great video. Nice job removing those Phillip's head screws. Mine won't budge.

Wow you're actually explaining how this stuff works... this is what I'm looking for thank you

It is a very professionally presented and explained with knowledge of IAC function and it is very helpful to me thank you so much for sharing your knowledge.

Part is about $245 at NAPA, roughly $30 shipped on ebay. I opted to clean the one on my 98` with 112K Corolla as described here. And it is back to normal now!

thanks for showing how the valve looks and works, it helps understand what is actually going on. Great vid

I was searching for a method without taking the whole throutle body off. Thank you very much!

Wanted to say thanks. I wish I found your video a week earlier, as I already bought the new part, but even so, showing how to take the throttle body off, and that you don't have to drain the cooling system (as my shop manual suggests) means I might actually get this done this weekend. Thanks again!

Very helpful. My wife's car is 1999 Corolla. Not enough space to work/open the IAC. And need specialtool to remove the 2 bolts. I have to remove the throttle body. Thanks for the video. The best one that shows on how to clean IAC valve.

While learning about TBs and IACVs, i didn't understand why coolant was even needed thru the IACV in the first place. In a toyo forum, a mech said the purpose of circulation coolant thru the IAC and TB is so ice won't form inside the TB in cold temps. Which made sense to me, since i've read that the colder the intake air the better the combustion. I guess a warm TB won't heat up the air too much, yet will keep condensed water from freezing inside. In the video you state 'The temperature of the water changes the range of motion', which is incorrect. The range of motion of the IACV gate always remains constant regardless of temp. Cheers

great video, just did this to my 97 camry this morning and worked like a charm! Thanks again for putting the time in for this video :)!!

No need to disassemble or remove throttle body. Efficient & simple method of freeing sticking ducted shaft clearly explained here. Thanks

Needs oil after cleaning, spray a shot of WD 40 in there the same way you explained with the carb cleaner by holding your finger on the vacuum hose port and submerging the tumbler for a few seconds. Cheers!

Now that method is a time saver.

i just bought a 97 mitsubishi mirage 4cyl. the setup is nearly identical, so this video really helps. i didnt really know what i was going to do to fix it. maybe i should clean it out before replacing the whole thing. great video.. thanks.

I learned so much from this video. My 94 Lexus looks similar. I've had it for a little over a year. Had it tuned up etc at mechanic when I bought it but it started idling very low and speedometer would not work for a few miles when cold, and would keep giving me spark plug codes. I finally braved it and decided to clean throttle body and mass air flow sensor. Even though I did not have the time to really do it this time, and for fear of breaking another hose, at least I learned what that notch was for and cleaned it somewhat. Anyway, the throttle body was horribly filthy so I can imagine that air control valve thingy, and the air filter. The car runs 90% better and I will take that part off next time when I can have someone with another car just in case. It did give me a weird code that just would not come off, I think a PO773. After finally arriving home after 74 miles, I turned car off, took key out then put key back in and just turned it to on without cranking and left key in for almost a minute and took key out and restarted car and code came off and did not come off. Thank you so much. I am a woman and could not afford a mechanic at this time or most other times

Terrific Video! Clear, concise explanation. Just add my comment to the chorus of approvals! Really appreciate your time and effort in making this excellent video! Cheers.

Well Done! I cleaned out my IAC valve your shorthand way for ~5 minutes and noticed a difference in car shake reduction when the air conditioner is turned on. I used "CRC Thottle Body and Air-Intake Cleaner". Thanks for your helpful video! For anyone who had issues removing screw(s), I stripped the head off of one of the screws using an impact driver but I managed to remove it with "Vermont American #2 screw extractor (package says it's supposed to be used in conjunction with a 7/64" 2.8mm drill bit). Prior to using that extractor I had tried easy outs as well as left hand drill bits to no avail. When you feel your drill hesitate your probably close to extracting the screw.

You brought joy to my life, I want to follow you, and learn your teachings, oh wise one..

I have to do this to my 92 Previa with the 2.4L UNDER the driver's seat, ohhh what a gracious joy that will be lol. Really enjoyed the info in this video!

Great video ! Don't let a mechanic replace the IAC valve without trying this first. The new valve is over $200 ! If you don't have the hose that connects to the crankcase don't attempt to clean the IAC while it's on the engine. All the cleaner and chunks of carbon will be sucked right into the motor the first time you start the engine. Take the throttle body off the engine first. I rebuilt my niece's 2001 Camry's 2.2L engine. The car had been sitting dead for over 2 years. After the rebuild the engine ran great, but idled too fast once warm. I found the IAC had locked up with carbon AND the motor's windings were open. (I should have checked that all out during the rebuild.) There are 3 terminals to the IAC motor. Measuring the resistance between the middle and either of the outer terminals should result between 16 and 23 ohms (depending on the application). Mine were 56k one side and completely open on the other. I'm off the the junkyard !

You sir, are the man! This worked a treat on my 92 camry. had problems with cold starts and rough idle- when it got to the shaft it would barely turn- a few minutes with the throttle body cleaner it freed right up Thumbs up!

Very useful, thank you for posting. Greetings from down under!

Awesome video. Very clear. Oh, great music for the time lapse.

thank you so much for the quick fix. I just did it to my gf's 2001 camry and it fixed the rough idle on cold start.

Wish I had seen this video when I did the same procedure for my 95 Camry. Written steps and pictures from toyotanation were great but video is much easier to follow through. Not sure if it was necessary but I soaked my with sea-foams over night and then sprayed more the next morning.

At 2:39 shouldn't there be a black o ring that seats against the circular area surrounding the magnet/shaft? Aside from that, I just used this same procedure on 2001 2nd gen avalon 1mz-fe, only difference was that the metal hose nipple that needs to be blocked is right underneath the spinning magnet, this nipple is angled and easy to access, I used a spare nitrile glove to block the nipple and then let the carb cleaner leak into the inside of the glove to dispose. p.s. as someone who loves learning about "why" and not just "how" to handle a procedure you have been one of the best explainers I have came across. Thanks for your time & insight sir!

Mi mother owns a 94 Corolla with the 4afe engine, it has exactly the same mechanism. It idles too high (1500-2000 rpm), tomorrow Ill try this. Its much more easy to do (less dissasembly). Thanks a lot for the video my friend, greetings from Paysandu, Uruguay PS: thumbs up for your video
