After watching your video,I decided to clean the throttle body on my toyota yaris.The
operation was a complete success and a much improved engine!!Thanks for sharing and keep up the good work.
Tom OConnor That is great that you did it successfully. I am happy that my video worked for you and for lots other. Keep up watching and interesting videos will come up. Have nice trips on your Yaris! Regards,
Thanks for posting this in so much detail. Most people would just replace the whole unit and call it a day, it's so much cooler to actually repair the problem- for free no less.
iretch Thank you dear friend for nice comment and complement.

Thank you for making this. I followed your directions and was able to remove all the carbon and get it running like new.
By watching this video i myself opened, cleaned and mad it free. Now working excellent. For the last 2 days i was roaming around mechanic who failed to fix the vibration problem of my 1nz fe engine. Thanx alot.
That is great dear friend if you solved your Toyota problem with success. This is the purpose of the video. Here on the following url there is another video on my channel recently uploaded. You may watch it and get a little more understanding if you may do the job again. Also there is a blog associated with this video you already watched and the blog url is here in the description.

LearningZone hi, my car fiat linea bifuel CNG halts while clutching or coming to a stop. the RPM suddenly drops below 500 and finally halts. Changed air filter, cleaned throttle body, but no success. some times I also get low oil pressure indication.
pls share the possible causes
awaits your reply.
thanks.....great job explaining and excellent camera work....I own a echo....best car I have ever had....thanks again...bob
Dear sir your way of teaching is wonderful. you are best teacher .God bless on you thanks for up loading videos different topic .Ma Sha All you have sound knowledge .
best regards
Thanks for the video. A little long but very helpful for the back-yard mechanic.
Thanks for liking and subscription. Regards,
My idle was crazy for a 2002 Grand Caravan - it ranged from stalling to idle of 2000 rpm and everything in between bouncing all over. I didn't think cleaning the IAC valve and throttle body would help much. Your video showed a thorough cleaning, unlike most others that just use spray and let the cleaner run off. I used a toothbrush to get all the carbon off with a spray type cleaner, and disassembled the IAC to thoroughly clean. I couldn't believe that it ran like brand new after reassembling! thanks for the help.
Tinkerer Dear friend thanks for nice comment. There is some times adjustment on the IAC motor or coil. You may align it carefully after start up the vehicle and putting it in idle. The position you achieve idle speed, you may tight the IAC actuator there. Also it is good that you may lubricate your throttle (Gas) wire and cable as after running long time it accumulates debris which is sticky in nature and creating hurdle in the movement of the wire in the cable and resulting in fluctuated rpm.
Thank you very much your way of teaching is excellent very simple and clear super
Hey thank you posting this video. Our car had trouble keeping the idle RPM steady. The RPM needle jumped over 2000 RPM. We did the repair on a 2001 wagon corolla using this method.Took the throttle body of the intake manifold. Then took the "Motor" out hack sawing the 5 sided screws. And changed them to a Philips head screws. No need to take it further apart and risk the caskets. Just use a spray solvent from the throttle body. There is a clear path in the intake manifold side. And spin the shaft. Doing this the junk got loose. And now the motor is able to spin the shaft freely. No coding or tester was needed. Just took a picture were the motor and shaft was located against the throttle body. The two passages are for coolant to make a loop in the TB. To heat it up. You can see the op video car has used only water at some point because the passage way is rusted shut. Again thank you posting. This saved us a lot of garage time. And patience. As here most mechanic's just would have changed the whole throttle body assembly.
terhhh87 Thanks dear friend for nice wording and positive comment. Glad that your car come to new life after repair. Regards,
Excellent video! This was exactly what I was looking for to fix my '06 xB.
Dear friend thanks for nice comment. Glad to know that my video is helping you! You may subscribe on my channel so that you would be notified on each upload. I am uploading technical videos frequently. Regards,
Very nice work! Outstanding results! Congratulations!
Thank you very much :-). I was able to fix my idling problem after watching this.
Thank you very much dear sir for nice comment. This is great and I am very glad that my video helped you and you solved your problem. Keep on watching sir lot and lots of repair, tutorial and informational videos are coming on. Regards,
Amazing. Thank you. I cleaned the TB on my Toyota XA but did not open the Idle Air Control Valve that you showed. My issue was not resolved. Now that i have seen you do it I will reopen mine and do it right. Excellent presentation and knowledge. Thanks again.
Thanks dear friend for liking. Wish you best of luck with your repair. After success, celebrate it here with us. Best wishes.
Thank you for your hard work. You help a lot of people. God will be good to you!
Thank you very much for liking video. You are right this video helped a lot of people on their cars most important and most critical part throttle body. As I learned it so I shared with others to give them help on this important part. Hope you may find my other videos also interesting.
Best presented video of this procedure. Good presentation THANKS
Now, with all these details, I'm very confident to go on this job on my Echo. Thank you!
Dear friend this is very good that my tutorial is helping you! If you are owning Toyota Echo, this is right channel for you. I will upload a series of video soon on this car as I shot many videos of repair on such car. You may subscribe on my channel so that you will get update on my each upload. Regards,
I performed most of what you've shown, I cleared the engine light problem, and it didn't reappered when I started the engine (but I did not make a realy big road test, so I might have a surprise in 200km). Also the car has started perfectly. That's the fun part.
At 4:41 in the video, you're removing the throttle body from the car. I can't see what happened when you removed the two hoses at the bottom.
Should I get worried if there's liquid dropping from those hose when I removed them?
By the way, there is no white smoke at the exaust when the car is running and my coolant level is ok.
Any idea?
Yvan Pelletier Thank you very much dear friend for subscription and happy that my video is helping you. This is what my aim is! There should be no problem when you will remove both hoses from the throttle body as they are coolant lines carrying hot coolant and preheating the throttle body hence fuel air mixture passing through it. the main thing is you should connect them back when you will finish your work. Also take care of you hand not to injure them while removing hoses that I am doing with my hand mostly!
There is no white smoke and coolant level is maintained, this is good sign. Please tell me in detail your car problem so that I would or anyone else would be able to give you some suggestion to solve your problem. Regards,
thank you so much mate, i just fixed my sons car toyota echo with your instruction, it was the best help.

You helped me a great deal. Best to you.
Great video on the Echo! Than you 🙏🏼
Great video, thank you. My 2004 RAV4 has some idle problems sometimes when I come to a quick stop. It clears up, but is still annoying. Had the throttle body cleaned but now I suspect the IAC.
Thanks for liking. Hope you solved your problem.
Many thanks from the UK
i have a 98 Camry 2.2l 4 cyl im going to try this on thank you good video! any more videos on Camry vacuum systems and fuel systems would be great...i subscribed!
MashaAllah nice video, jazakallah khair
i just did this on my 2004 Scion XB, it has the same 1.5L engine, and it seems to run smoother at idle now. I didn't have any real bad issues, but watching you take apart the whole IAC gave me confidence that i wouldn't break anything, but those 5 point screws?? WTH! I improvised with an Oscillating Multi-Tool and cut a slot in the screws to use a flat head screwdriver to remove them. upon startup i had to erase 3 codes that appeared P0102, P0113 and P0511 and it is all good. Thank you for a Quick and Great Tutorial. :)
How did you clear the codes?
Why did codes appear?
thanks a lot for ur tips to maintenance our car by self this is very good and i understand and can do very easy after seeing ur vedio thanks dear

After watching this video, I will do it by my self to clean the throttle body on my Toyota Vios 2003. Thanks so much sir, greeting from Indonesia. Salam
Wish you very good luck with your throttle body service. You may share your excellent results and feeling after your service here with us and celebrate your joy with us too! Stay tuned and blessed.
LearningZone dear sir, I have finished cleaning my toyota vios 2003 throttle body. But there's a problem with the rpm when the AC is ON rhe rpm going down, when AC OFF rpm going up. Can u tell me what's wrong?
@@Willy0981 have you find the cause? I think it's about ISCV solenoid coil that can turn a little bit clockwise or counterclockwise against the throttle body, if you see the hole on the solenoid, it can be adjusted, so you can increase the rpm when the ac on by turning the solenoid clockwise (if I'm not wrong). I will try that since I have the problem like you have after cleaning ISCV valve on my toyota vios 2004. My mechanic friend told me it can be adjusted, by turning the solenoid. Greeting from Tangerang

hello sir, here in my country we have the same car/engine (jdm right hand wheel) but here we turn on the left side the steering wheel.
your video is very helpful.
Greetings from Paraguay.
Thanks for watching and liking. You are right the engines are the same and the steering arrangement is different from country to country. Best regards,
Very good information! Thanks for the old fashioned way of repair! I loved it! Where do you live and where was the repair done? I hope is not your home.
sir wonderful lecture
Thanks the video helped
thank you for your time.
That's my pleasure. You may watch my other throttle body repair videos on my channel to get even more understanding of throttle bodies so that if you will attempt such a job on your car, it will be easy enough for you. Best regards,
Any videos on toyota 4runner 1992 on throttle body and vaccum lines having trouble my truck will not accelerate thank you for the help
Great video, I was wondering could you do another showing the calibration you mentioned in this video? Or maybe share details where to find out more about it?
Drewan Nicholson Dear friend thanks for liking video. I would show the calibration process the time I would get a scan tool! It needs an average scan tool to calibrate the throttle body. Otherwise it could be done up to some extent through mechanical tune up.You may subscribe on my channel as I am uploading frequently and you will get an automatic notification on each upload.

LearningZone The gasoline you put in your gas tank ?? Im curious what you are using in this video ?
Kaash Bragna Yes sure same gasoline in your car tank and WD40 spray for inside of TB.
Good job 👍
Thanks. Stay tuned.
Good job sir. Thanks for sharing .
+gas1989 Thanks for liking video. This video helped lot of people solving their idle speed for free. The sad thing here is even 22 people disliked this video till writing this comment. I don't know why people are disliking such videos? Did they pay me for that and the video was not according to their expectations? I know these people capacity, unfortunately they have no capacity to pay anybody a single penny! Regards,
i cleaned my iac valve and try to get it to work by connecting the con ector and the vacume line hose ONLY. does that power it up? it wast sucking any air or soing anything but i could feel a little vibration inside. is it broken?
Bom video irmão parabéns
Thank you so much 👍🌷
You most welcome always.
Nice Job
Thank you for sharing.
That is my pleasure dear friend. Keep watching my channel. there are many video on the same and different topics and many will come soon. Regards,
just cleaned mine today.. i suggest that u use acdelco carb cleaner.. it's so great at dissolving carbon....
Great!! One question, whats the model of the idle air control? does this video works for daihatsu terios iscv?
Angel Velasco Dear friend thanks for liking video. My car in the video you can see is 2000 Toyota ECHO. This procedure can be applied to many cars of same built. You may look at components of your car for the application of this video to your particular model. I never worked on one of your model so that I could give an advice. Anyhow you can send me images of your throttle body as email attachment then I would be able to give you a word on that. This video helped many people for solving their cars idle speed problems and IAC related problems. Regards,
Hi thanks for the great instruction. My 2004 corolla sedan is at 240000km. Yesterday without prior warning it started vibrating and idling rough and I couldn't get the speed up past 80kmph. I changed the spark plugs but it still does it. Should the IAC valve clean be the next step? What tool did you use for the 5 prong screws and what solvent do you use? Many thanks
+Netty Gretty The problem you are stating seems a serious misfire due to any good reason. The best way here is to scan the car using a scan tool. It will ease you job. It could be no spark misfire, no fuel misfire or no compression misfire. I addressed almost all three type of misfire problems in my videos on my channel. You may search my channel for other videos to address your problem.
The throttle body cleaning part is coming latter to bring your car to nice performance like new. First is to address the other issue like misfire. Hope you get my point. Share your success with us. Good luck. Regards,
wow it's work thanks for that .keep on
Thanks for liking and subscription. Regards,
Sir i wanna thank you for yr splendid job but regarding this throttle body i have the same throttle for a corolla i disconnected the wire for the IAC while my vehicle is on nothing happened no change at all can i conclude this IAC is damaged? Thank you for your generous time and effort
Thank you mate..
Thanks for liking and subscription. Regards,
Great video and well worth watching.Did you use an new gasket for the throttle body? or was the old one ok?Own a yaris myself and will attempt to do the same.
Tom OConnor Thank you dear friend for liking the video. If you own Toyota Yaris or any Toyota, you subscribed a right channel. I used the same old gasket as it was in good shape and condition. I used same old gasket on many cars throttle bodies after service and they worked flawlessly. You may check your Yaris throttle body as if it is the same as one I showed here or it is a drive by wire (motorized Electrical type). If it is Electrical motorized type then the cleaning instructions may vary. But you can do it yourself without facing any problem. Regards and good luck,
Many many thanks.
You most welcome always dear friend.
Hola buen video amigo tengo el mismo vehículo suyo desarme el cuerpo de aceleracion limpie la valvula IAC de la misma manera que usted explicó arme todo bien lo único que el vehículo quedó muy acelerado en 3000/rpm revise sensor tps y esta bien al igual que sensor maf mi consulta es si sabe de alguna manera de bajarle las rpm o te dria que hacerlo atraves de scaner? Bueno espero me pueda aconsejar saludos desde chile 👍🇨🇱
Seven years later and I’m gonna try this on my Scion xB
Awesome job ! Just curious how do you get those 5 starred screws off the iacv, i've already cleaned everything as much as I can just found your video after I thought I might need to remove those to do a more thorough job. Also im wondering what cleaning solvent your using ? My CRC throttle body cleaner is almost empty lol. Is it ok to get that liquid on the iacv sensor pins ?
Kaash Bragna Thanks for liking video dear friend. Yes there is no problem of your cleaner with electrical connections. You may watch my other video on IAC actuator screws modification. They are real pain in the job. The url for the video is as following. Regards,

Hello Engineer, thanks for the video. Very informative. I'm a Toyota Vios user (2005 model) if you may can share some idea about what i have notice in my car, when I turn-on all the lights during night time, I notice the engine will vibrate more and the RPM will decrease a little. Any suggestion about this? Thanks.
Thanks for liking video. That is great if my video may help you. Your car needs the very same maintenance as the problem you described is due to a dirty throttlebody. Please watch my other video on the same subject I upload on my channel. Here is the link for that:

Hi...I attempted to remove the throttle body and it wasn't hard but when I got to the two tubes that connect to the Idle Control Valve, bottom back side of the Throttle Body, I couldn't get leverage to get in there. Would you recommend removing the Dip Stick, it seems you did, so that you can remove them and harder, connect them back lol.
This was for a (slightly) different vehicle, but just what I was looking for. Thanks.
Dear friend if your car is close enough to this particular car, I am uploading tons of videos on this car here on my channel. You may subscribe so that you will get update on each upload. Regards,
Dear Learning Zone: Thank you for your attention,,the engine can start normally when it's cold .but never can start and become heavy when the Engine is hot ,I check the spark plug it works but not blue spark it's orange color ,the engine size 2.0
I watch ur video I try to open this system because I open every things in ,,thank you
As I asked you before you may test parameters like spark and fuel injection pulses when the engine is hot and reject to start. Then you will confirm which parameter is missing and make some conclusion from where that particular parameter is missing. If you will get something missing then your engine mechanical is OK but dig behind that parameter which is going to miss. Hope you understand my point. Regards,
LearningZone my engine starts and goes off immediately. what might be the cause?
when i clean my 1sz-fe engine's iavc with carb cleaner it works fine for 1k kms or so .. bt it start whistling again and i have to clean it again .. wht cld be the permanent solution of ths problem .. please advice
Hey good video man I have a problem with my Toyota bb low acceleration wen petal push down I have changed the spark plugs didn't see any problems with the coil packs
On top of the plugs wat u recommend I should do next
Thanks fili
Try adjunsting the accelerator cable
What is the size of the torx screws which hold the electrical part to the mechanical part of the IAC?
Torx size isn't very critical but the problem is it is a five point torx which is Toyota special tool.
For anyone who wants to know, those two screws are 5-point tamperproof. The only place I found them, other than online order, is Pep-Boys. #9684 T-20 made by CTA MFG Corp. Cost around $5.00 US
thanks for the info!!
Thanks for this, ordering up a 5 point socket based on your info. Hate it when non standard stuff is used!
@@the.internet where did you find this ?
If you want to know there is a set of 10 sockets on Amazon just search 9684 5-pt Tamper Torx Socket - T20
I got huge amount of rich burning. I can't find a vacuum leak anywhere. I did clean the throttle body. Not sure if I installed it wrong the end cap for IAC.
What is the sound around 15 mins. The buzzing/droning/humming sound when you rev the car? Where is it coming from? Thanks
Sean Green Dear friend look at the video, try to understand and learn something. Don't try to point useless things for teasing. You can't tease me by any mean. Regards,
Ok I have a problem with my premio 97 code 33 I already clean de iac valve still check engine Licht on what can bi the problem
CAN YOU Throttle Body HAVE EFFECT on shifting your gear please help my speed line goes up to 3 and my rpm goes up to 3000 then it runs irregularly
I had Toyota Camry 2001 when I parked it in sun light its shows engine check light and engine oil light and car becomes little heavier while under cover parking car had no issues pls advice I go to lot of workshop but not found any solution
Hi, Thank you for your video. Very instructive. I did clean my throttle idle valve and not sure I did put the black connector at the right place. But my problem is the same. high rpm at idle, but it change when I turn on fan in the car. It could be 1000 rpm with the fan off, but rise to 2000 rpm when I turn on the fan, not always but most of the time. There is nothing else in the car ( with electricity) that trigger same event. Turn on light, hasard, AC, , no change in RPM.
Not sure where to look now, do you have an idea ?
Thanks in advance
+Solution Netcomm
The rpm issue happen also with the fan off, it could be revving at 2000 and sometime more, seen 3000 rpm with the fan off. I disconnected the valve idle sensor and problem is the same.
I've seen situation where I turn on the fan, and it barely change the rpm. I'm really lost.
+Solution Netcomm
It is a Matrix 2003 Toyota, so similar to your car
Thank you again for your video.
What I did to test the valve, is to remove, the valve and put a full gasket between the valve and the throttle body. Did a bypass for my water so water doesn't come in the valve anymore. This confirm that my valve is defective and I ordered one. Right now, I don't have the choke and in the morning, idle is rough. But as soon as the temperature of the engine rise, idle is ok and I could turn fan on or off with no impact on rpm. Can't wait to receive my new valve.
@@solutionnetcomm6139 don’t you get a jerk when shifting to D when on rough idling?
tahnk help alot
Thanks for liking and subscription. Regards,
Great video.But IAM behind on calibration.Where is calibration required and how it done? Amplify on calibration.
Thanks. Calibration is required in the end after fixation. For this model it is done mechanical by setting up idle air control assembly to some point where you get good idling speed. For newer models you need scantool to do caliberation. Sometimes you need to fix it and drive car for a few key cycles and its ecu caliberate itself. Stay tuned.
what product you use to clean. you said not clear.. the liquid?
Thanks for the video. So what is the exact reason of idle rpm change when the electrical load changes?
+Reza Farahipour Thanks for your comment. Nearly the same dirty throttle body is one main reason for such a problem. In very rare cases it could be a vacuum leak in the system.
+LearningZone thanks for the reply! so it has nothing to with the alternator.
+Reza Farahipour In my experience in such case alternator is not at fault. If you will clean the throttle body, you will be able to solve such issue.
Radiator water runs through the idle control valve. Why? Is there a thermostat inside somewhere.
HI. The video is very good. May i ask what kind of cleaner have you used to clean the throttle body in the video?
Wish you good luck with your repair! The cleaner and solvent used in the video is regular gas (Petrol). You can use anything like gas, WD40 or carb cleaner. You may watch my new video on the same subject on my channel to get even more understanding of the job. Here is the link: th-cam.com/video/lsvpWJG-dK8/w-d-xo.html
