My daughter's 2009 Yaris with the 1.33 NR1-FE stalled on her using the ECO mode coming home from a trip to Scotland on holiday. The Engine light came on, but after turning the ECO off the car stared again. Not sure that had anything to do with it, but she was back on the road again and got home. I have an Xtool analyser which showed P2112 "Throttle Body Actuator Stuck Closed" DTC. My local Toyota dealer came back and told me "It needs to be replaced, it will be £1057 including VAT (Value Added Tax). I said "okay" and hung up. You just saved me that much cleaning it myself. You are worth your weight in gold Sir. Thank you very much. 😉👍

This is the exact kind of basic maintenance shop-class type video that is so beneficial to us who like to dabble in the "easy" part of car repairs. I've been warned not to manually move the butterfly on some cars, so it's good to know that's not a problem on Toyotas. I'm thinking what would I have paid for this as a class? And then thought, if only a tiny fraction of Ahmed's viewers donated just $1 to his channel through that Patreon account, it would be a nice "thanks" to him for taking the time to do this video.

Warning, I’m not a Toyota mechanic but was an Army mechanic for 8 of my 25 years, so I basically changed parts. Hesitation can be a few things. If you have time you should remove the throttle body, and get it truly clean from both ends, plus you can see the condition of the mesh gasket under the throttle body. (My mesh gasket was falling apart). I had a spare in my tool box. So, While I was still under the hood I cleaned the Mass Air Flow (use cleaners specifically made for that part, as he mentioned). After doing that, I checked the spark plugs; some of my plugs were gapped at twice the recommended gap. New plugs, checked the gap. (I check gapping on new plugs, that’s just me) since I was still under the hood, I properly cleaned my K&N air filter. (I was cleaning it wrong for years), since I was still under the hood, I was low a quart of oil. Filled to proper level. Closed the hood, allowed the air filter to dry. Next day, took it out for a 20 mile test run…..it ran weird for a few miles then got on the highway. My 2010 Toyota Tundra went up to 90 mph without pushing the pedal to the floor. It was like a new truck again. I neglected it for 2 years…….. I’ll never wait that long again. Being that I did all that maintenance at once, I couldn’t pin point what the true cause of the hesitation, but then again everything I repaired needed to be done.

Awesome video. My car was throwing a code related to the throttle body and the dealer wanted to replace it at a cost of $800. I declined, took the car home, and cleaned the throttle plate. That was 18 years ago, and ever since I have been cleaning the throttle plate every 2 years on the original throttle body. No more codes and I still own the car. Now I do it to all my cars.

This is all I had to spend to do this myself. I hope you make money from these videos forever, you deserve it. Thank you for sharing your knowledge with everyone.

This channel is amazing. The Car Care Nut is going to help me keep my Corolla's running for my entire lifetime. Love this channel, thank you.

I wish I found this video 1 month ago! I changed the spark plugs on my 2002 camry 3.0 and disconnected the battery. After that the idle was super low and would not idle after it warmed up. I back tracked my every move to find a possible vacuum leak. After replacing pcv valve and hose, egr gaskets and vacuum hose. I found nothing. I began to worry. It took me awhile to figure out to clean the throttle body. And luckily all was better. Great videos here. Thanks

I was watching this as I was waiting in my Toyota dealership for my first 5,000 mile service on my new RAV4 Hybrid. I asked them if they would clean the throttle body before my 3year/36,000miles service expires. They said no because Toyota recommends it be done at 50,000 miles. I am very grateful that you are providing invaluable information for us Toyota owners because we can’t always trust the dealerships.

As a Lexus and Toyota owner, this channel is invaluable! Subscribed early on.

Real talent for explaining these complex machines to the average owner! Even a more advanced wrench turner like me gets so much from your work here! Appreciated!

Thank you so much for empowering me. Because of you I now own: 2 ton jack 2 ton jack stands Breaker bar Tool box set with extensions Before you I owned a couple of screw drivers and a hammer. Did my first oil change a week ago. Changing cvt fluid is next on my list.

Thank you. Your channel is an invaluable asset to the car care community.

I am a Toyota man forever. You couldn’t pay me to buy a Ford, Chevy, Chrysler. I just cleaned my throttle body today. I followed your steps to the tea. Thank you for the great videos, especially the one on the transmission fluid change, drain and fill. Knowing the correct temperature for the temperature check.

Thanks for clarifying pushing the throttle butterfly open by hand. I’ve seen many other videos saying you can’t touch or move the plate by hand. This makes it’s nearly impossible to clean.

This is the most comprehensive explanation I've heard about how the TB and the throttle actuator works. I've worked on my own cars for the 35 years I've been driving, and have owned 19 cars so far. This is much better than a Chilton's manual (nothing against them though. They've helped me out a lot).

Man thank you so much. I have a 2ARFE 2013 Camry. I kept procrastinating this job. When I finally did it I was actually shocked. Car feels brand new. My gas pedal feels way different. I appreciate everything you do for the Toyota community. Your videos are always a help. Initially I was idling at 2k rpm and not even 10 min later I was at normal idle and no codes spawned either. If you have a 2ARFE engine the job isn’t that bad. Just need the proper tools.

I had my throttle body cleaned and it works very effective I watch as many videos from your channel to keep me informed . Excellent education you provide thank you for everything it is so appreciated you can't imagine .From a viewer in Montreal Quebec Canada.

I couldn't believe how easy it was to clean my Throttle Body Plate on my 2019 Toyota Highlander. Thank you Sir.

Love it. Most of the most overlooked maintenance items. I like mine every 30k miles. Brings down the RPMs at idle. Nice and smooth. I clean the MAF sensor every oil change. My 2003 Tundra with 167k miles, still runs strong because I don’t mess around with maintenance. As my Dad beat into me “take care your vehicles and they will take care of you”

Fantastic note about the ten amp fuse “after a jump”. Thanks so much. Helped me in a parking lot today. The checked the fuse before I watched your video, and it seemed ok, after watching the video, I replaced the fuse and it worked. Saved me a tow. Thanks again.

You're awesome I've learned so much from you as a DIY, really respect the fact that you always end with May The LORD bless you and keep you.

AMD, thank you so much for creating this video. As someone with an electronics background, this stuff fascinates me. I successfully cleaned the ETB in my 2007 Lexus IS250 (4GR-FSE). Brilliant design that relearns on its own! Simplicity is the ultimate sophistication. Not sure if it was just my impression on a quicker relearn, however, after full warmup, before engine shutoff, I placed the transmission in Neutral and watched for about a minute as the computer quickly adjusted idle back to normal. I must now learn how to do this in my 2014 Acura RDX (J35Z2) where to my surprise Honda calls for PCM Reset and clearing of TP learned value. Hopefully my Thinkdiag scan tool will do the job. To me, Toyota and Honda still make the best vehicles in the world - hands down. ¡Mil gracias!

Thank you for your thorough explanation, details, what not to do specifically, etc. Also for keeping it simple just what we need to know/do. Good work!

Best Toyota technician on KZfaq. You are a wealth of knowledge and reason. Great show.

Many years ago I took my car to a mechanic for poor idle and stalling. On the invoice it said throttle body cleaning and I was charged almost $100. I didn't know what it was at the time but found out later on that it is a simple job. Ever since I've been cleaning it every 50k miles or so.

I cleaned mine on my Camry last year at about 158K miles. I got the car used at about 80K miles. Really wasn't all that dirty hehe. Cleaned it and the MAF sensor. Car idled a little high a couple days like you said. Good to go👍 Great video. Didn't over complicate things. Basic stuff.

I watched the first 17 minutes of this video but needed to hear the 18th minute to solve my problem!! lol. I cleaned mine and it was idling really high afterwards and I freaked out because I didn't watch this video until the END!!! Thanks my friend, you make owing an LS430 even better!!!

Thank you CCN ! This made a huge difference to throttle response and performance. Took 20 mins to get idle to settle down. Everyone should be doing this....

I am in the process of buying my first Toyota, a 2021 trd tacoma off road. I appreciate your expertise and advice, keep the videos coming

Another wonderful video, AMD! I recently did a throttle body cleaning where I took it off the intake plenum (and replaced the gasket as you suggested) to clean it front and back, but it was a bit confusing to see tons of contradictory warnings online about the procedure and claims of destroying the TB if the throttle plate is moved, calibration issues, etc. Thanks for clearing up the misconceptions! As you said, after cleaning the idle was initially high, but after driving and idling for 20-30 minutes, it stabilized back to normal. The throttle response improved, and possibly fuel economy as well.

Great information. Just started working at Toyota as a service advisor and will study this video to help suggest accurate information to the customers when the technicians recommend this service for their car.

Love this channel, just bought a 2009 toyota corolla and did a lot of minor things I have seen on your channel too it this car for me was a excellent second car with 17000 miles on it and it still runs great.

Sorry to hear about your dad passed, RIP, our prayers for you and your family. Thank you for all your help

You deserve an award for making great content. Thank You. I'm ready to clean my throttle body on a 2003 Lexus IS300.

Oh my gosh. What a good vid. Been working on my cars for 55 years. Never had better info. Thanks young man! Cheers from Northern Ontario.

I tried this on my 2AR-FE. Such a pain getting to the throttle bottle let alone the bottom part of the throttle plate, BUT it was totally worth it. I bought my 2012 Camry used with only 80k miles and noticed it idled above 2k rpm upon start up. It seemed excessively high for a start up but it would drop to around 800 rpm after 30 seconds. Anyways, I cleaned this completely and it was totally a game changer. Thank you!!

It’s really a simpler way cleaning the throttle and useful. Save my time. Thank you!

Thank you for explaining the "why" of why you are cleaning the throttle body. Great informative video.

Best video I've found on this subject .I'll be removing all of this on my 04 highlander soon to replace the spark plugs and coil packs.I definitely want to do this cleaning before reassembling every ,thank you!

I remembered seeing a video on how easy this was to do, while I was at the service counter and Toyota was asking me to pay them $140 to have them do it! Went back and rewatched this today, and thankfully your videos have once again saved me a lot of money!

With the quality and no bs content I can see you growing to 1 mill in due time!!

This is absolutely the best video I've seen about cleaning throttle bodies. Very clear and concise and videos is high quality. Thank you so much! I've subscribed!!

Great info. Took all of two minutes and the idle drop is gone. When I first started it after cleaning the idle did bounce from super high to normal a couple of times. Felt like she was trying to say thank you. Again the instructions where much appreciated.

Thank you, I inherited my wife's 2007 4runner, with 115,000 miles, I'm doing complete all maintenance. You gave me enough confidence to tackle this, thanks again.

AMD since I had to remove the throttle body on my 2012 Highlander when doing the spark plug replacement (using your excellent video) - it was the PERFECT time to give the throttle body a good cleaning - front, back, and edges. A soft toothbrush is a helpful tool - I had some extra unused ones from my dental checkup 😁 I used the CRC 05078 Throttle Body and Air-Intake Cleaner. CRC is widely distributed so it should be readily available at independent and chain auto supply stores (in case a Toyota parts counter isn't nearby...) After cleaning the throttle response is noticeably improved; throttle tip-in is more sensitive; and the idle is butter smooth.

The Best video on this topic i have seen. You covered every angle and issue. You really do make a great teacher. Thank you

I have a 1995.5 Tacoma. Never cleaned the throttle body until seeing this video. It needed cleaning... it was dirtier than the one in the video. Next job I did (later) was to change the spark plugs. It was easier to change the plugs after removing the air intakes to the throttle body. They are easy to remove but next time I will do both jobs at the same time so only having to remove the air intake hoses once. Hope that helps someone else. Absolutely love this channel. Thanks so much for these videos.

This guy is the greatest Toyota mechanic. I’ve learned so much about my 4Runner watching his videos

Thanks for this video AMD. I just finished cleaning the throttle body on my 2015 4Runner Limited with 59,000 miles using your procedure. Had a fair amount of carbon built up that I was able to clean up. One thing to watch for is when putting the rubber intake hose back on the throttle body, be sure the under side of the hose doesn’t fold over while trying to push it back on. I had a bit of trouble trying to push it back on. Finally, I reached around and felt what the problem was and had to pry the hose onto the throttle body with my fingers. Once I got it started, it pushed right on.

Great Video. Lately every video has been in time with my own maintenance needs. This weekend I will clean the TB on my Tacoma, Rav4 and my Wife's 4Runner. Thank you

All the 2001-2007 Sequoia videos say to remove the throttle body to clean it. Mine is now 19 years old, good luck removing plastic parts and hoses! Providentially, I found this video. Thank you! It was a piece of cake. Only problem was the Check engine light, the VSC off, and VSC trac lights came on after the job. Drove the car to get something for like 20 miles and the lights did not come off. Next morning turned on the engine and the lights came on again. Turned car off, disconnected battery negative cable for like 30 seconds, then connected it again. Started car the warning light disappeared. Job completed. Once again, thanks for a great video.

thank you for the video, tons of needed info. worked on a throttle today, cleaned it out and got it working again. car is running great, saved a $900+ trip to the mechanics.

I had my mech do it last month! What a difference from night to day. My car runs SMOOTH. It was its first cleaning and there was plenty oN the outside rim and the throttle. Gently done, works great

Thank you. My 2006 Camry is idling poorly right now. I've cleaned the mass airflow sensor and looked for vacuum leaks. Will try the throttle body cleaning next. I too scared to clean it until this video. Many thanks.

Thank you, AMD. I am new to this channel, and a total noob when it comes to automotive maintenance. I have a 2005 4Runner SR5, almost 260,000 miles, bought used so 200,000 of those miles are mine. This video, and some of your other videos, gives me the confidence that I can perform my own maintenance. After watching this video I cleaned the throttle body, and the MAF, the idle is high as expected, but the 1GR-FE runs much smoother. Given the high price of new, and used, cars, I'm trying to keep her running as long as I can.

Thank you for the clear and concise description of throttlebody operation and why they need cleaning. I only watched half of the video because I am going to be working on a 1990 Ford F150 but your explanation was excellent.

This video has the best explanation of how things work that I have seen. I tuly appreciate the time you spent to explain the basics.

Thank you for the detailed explanation and demonstration. I was demo by my mechanic buddy about throttle body cleaning for a Toyota Vios with 1NZ-FE engine, which then he asks me to try DIY it at home at a certain interval to ensure the engine runs smoothly. He did mention about have to flip the butterfly valve gently but I didn't further ask much that time. And some mechanics here even told me better don't anyhow touch the butterfly valve. With your explanation, now finally I understand what's the reason behind. So that small electric current that generated by throttle body motor if flipping the butterfly valve too fast is the killer here.

best video out of 50 others I have watch on cleaning throttle body. Now I'm ready to do mine tomorrow :) thank you

This is very comprehensive information. For DYI, thank you for this effort to explain the what, how, and why with this topic.

OMG. Every time I see your videos I learn more and more. I feel like I'm becoming a real mechanic 😂

Love this channel , as a Tundra owner, i learn something new on every video

Thanks! I followed this video, cleaned the throttle body and LIFE IS GOOD! 😀

This channel and Toyota Maintenance channel are the 2 best for this content. Thanks!

Great info.thank you.i cleaned my 06 Tacoma 4.0 only. Once it has 234000 miles on it and it is idling rough so thanks for reminding me to do it more often.

I was waiting for this video! Thanks AMD! Great and fantastic content as always!

DIY for decades, this video helps me, very well done. Thanks.

When I hit the stair climber, this is the channel I watch. Love the videos. Great advice and maintenance tips and tricks. Thanks you greatly. Jade

Just finished cleaning mine last week -- I actually removed the throttle body and cleaned the back side as well, even used a toothbrush to reach all nook and crannies. Final product is almost like new - not a smudge in sight. Also wiped the inside of the intake plenum carefully as far as I can safely reach. Thanks for another great video and more importantly empowering DIYers - keep up the good work.

Great content. The information in the beginning is exactly what I needed. I had to replace the heater bypass tube and in doing so I had to remove the intake manifold. When I did this the throttle body had to come off and I ended up cleaning up both the throttle body and manifold. Upon reassembly I had an idle speed that was higher than before the maintenance but not above 1000 rpm so there was concern I may have missed a vacuum hose or connector. Double checked every connection and all was good. Your info cleared up the idle condition and I'm now confident it is perfectly normal. Thanks for the excellent information and I am now a subscriber!

Thank you so much for making this video. I followed the steps you outlined and everything went smoothly - my idle is smoother, I have better acceleration and hopefully I will have better fuel economy. This is an excellent video. 😊

The style of this video was perfect, friendly whilst remaining professional and inspiring to do it yourself...just take care and pay attention. I’ll be using this as my main reference to help my rough idle issue, thank you so much! ❤️

Great video! Thanks, AMD! I saw my mechanic was spraying profusely some carb cleaner into the throttle body while the car was running and he told the car owner to keep the engine revs between 2 and 3 thousands RPM. He literally used a good half of that can. And now I see, you don't need to spray it inside, but just wet a microfiber towel and wipe the buld-up off!!! I've learned this lesson!! Not going back to that mechanic!

Another excellent video! I’ve got the same 4Runner engine and went ahead and cleaned my MAF while I was at it.

AMD I really like your tutoring. Plain and simple straight to the point. You do a fantastic and valuable presentation! Love it! Will return.

Fixed my idle/stalling issue with a 2004 Sienna. Thanks for the great video!

Thank you for your expertise, straight to the point and taking time to explain the why's. Very helpful. Happy I decided to watch your video. Other video showed to take it all apart even the gasket. Yours make sense I trust your video thanks again.

Thank you, very valuable information, I thought you just spray it in and it dissolves the carbon. Now I know why I watch this channel. 😊

As a Refrigeration Mechanic and Car Maintainer I appreciate all tips from a Honest Toyota Mech. Thank you dear sir for your input. I have a 2006 Highlander that is getting a timing belt this summer. O joy. Anyway have a great day Brother. Calgary, Canada

Thanks! Saved me 170 bucks at local dealer. Your the best!

Just did my wife’s 2017 Prius with 25,000 miles. Outside was pretty clean, inside just a light shade of black but an easy job!!

The best Toyota channel

Okay, I've watched a bunch of your videos. I love them all. This one made me a subscriber. Thank you for sharing your knowledge with me.

Wow!!! That was a master class on throttle body theory and maintenance. Thank you so much. 👍🏻❤️💯

So much info in all of his videos. Not a wasted word. Everything he says has importance. Thanks

Great work and very informative videos . Thank you for making the videos and please continue to make tons more

Thanks Ahmed! I did this to 3 of my Toyotas today. One was pretty clean already. The other two showed a big difference. I did learn something about hose clamps today. I was struggling getting the duct back on the throttle body of the 2007 Solara (2AZ-FE) when i noticed you could "lock" the hose clamp open and put the duct on and then release it once the duct was back on. Pretty cool.

And as usual; you nailed it; cleaned my throttle body and MAP sensor; idle was a little high for about 2 drives; but WOW; did my car run better !!

Thank you brother… you really explain things really well, thanks for the heads up on the idle running high after the cleaning

Priceless video! The best channel on youtube!

You a great teacher. Even one without any experience of a car is able to follow and work on the guy!

Excellent video as usual with important details to keep my Toyota running smoothly. Thank you.

Found this channel a few days back. Excellent videos! I currently own 3 Toyotas and do most all my own maintenance. These videos extremely helpful and detailed. Thanks again!

Thank you Sir for your invaluable information and insights into making car care maintenance understandable

I did this truck started strange but settled in within a second. Thank You Sir.

My 2018 Tacoma with the 2.7l has an unsettling vibration at idle while in park, did some searching and cleaned the throttle body. This video cleared my anxiety of needing a recalibration. The truck has 33k miles on it but a small amount of debris build up on the TB. I couldn’t believe the positive difference in throttle response and acceleration after cleaning, I’m surprised at the benefits because I didn’t think it was even THAT dirty. Apparently the idle vibration is common but it’s still annoying. I look forward to seeing if the vibration goes away after this cleaning (the vibration is intermittent so I couldn’t tell if cleaning the TB truly took the vibration away but I 100% noticed a difference in acceleration. Thank you for the video! I look forward to the rest of your channel when maintaining my new truck!

Most excellent video as usual. Thanks for posting. I googled CRC throttle body cleaner safety sheet and found on their website that their TBC is 90% acetone and remaining being inert CO2 essentially. Think I am going to clean mine today. Thanks again for posting!

As a non-owner of Toyota or Lexus, i still subscribe and watch.

Your advice and know how gave me the confidence to go through with this and my Mazda3 is now running smoother, faster and cleaner. I don’t remember her performing this well, even the idle is smoother....not mention 16 years of carbon gunk, gone. I’m absolutely stoked with the results, thank you SO much! 😁❤️

this is the best TB cleaning guide i have find, i was able to get rid of a p0101 on my mazda 3 2010 thank to you my friend, that damn code was driving me crazy, thank you very much.
