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.
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.
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.
you probably hadn't even changed the air filter yet in that Rav4 and you wanted throttle cleaning? Completely not necessary :) But, its good that you care about your vehicle!
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.
I am right there with you on brand loyalty. Save the planet and your money. Buy a well maintained used Toyota and take care of it and have a car for 20 years with little hassle.
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
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. Update: I can now do drum and disk brakes.
Buy a cordless impact wrench with maximum torque in the neighborhood of 150 ft-lb. It will be light and small to maneuver. Yet, it will be capable to take off 95% of the bolts on your car including the wheel lugnuts. I am a home mechanic and it made working on my car fast and enjoyable. I live in US and my impact wrench is made by Bosch model BOSCH GDX18V-1860CN 18V
Good for you and anyone learning maintenance and repair. You can't get a better teacher than Ahmed. My best advice is to upgrade to a 3 ton jack even if you have a small car. A 2 ton jack can be unstable if the floor is not level. Also, the jack equipped with your car is for roadside emergency only, like a flat tire. Be careful and use wheel chocks.
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. 😉👍
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!!!
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.
I agree, to have the experience of a Toyota Master Tech explaining in great detail how to perform repairs, maintenance, and what to watch out for is very valuable information and real world experience. I think a donation is a nice thanks to Ahmed. I am a recent subscriber and donator and I look forward to more videos.
I’m just learning with my first car, it’s a 2020 Corolla xse and I’ve seen maintenance on these cars is easy. Next time around I get another car I’ll just do all the maintenance myself
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....
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”
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!
Outstanding video! The tip about NOT forcing the plate open too fast is something I have never heard before. And thank you for the tip about the high idle. Keep up the good work!
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.
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!
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.
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.
@@Sci-Mon1no You must work for the stealer Only takes 10 mins to clean it and no cost at all just a shop towel and throttle cleaner. They making bank charging $300 for that
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.
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.
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!!
I'm currently a Saab owner, but have done some work on my daughter's 2003 Camry. That thing was NEE-glected! She was scared when I mentioned cleaning the throttle body, but very happy after.
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.
as usual, your explanation and reasons why you don't do certain things are second to none... keep sharing your knowledge, pal.... you are teaching me every day... thank you
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.
Glad I found this. Based on watching a few other videos on this topic, it was clear to me that I was not to manipulate the butterfly by hand and that I would need to perform a "relearn idle" procedure afterwards. Instead I intended to turn on the ignition and then have someone depress the throttle (or mechanically hold it open). After watching your video I felt comfortable manually manipulating the butterfly, at least on Toyota/Lexus cars. (I also cleaned the MAF sensor .) Anyway, the first part of the "relearn idle" procedure is warm the car up. On startup, the idle was about 1900 RPM. At the conclusion of my warm-up drive of 5 to 6 minutes the idle was down to 675, which seemed spot on. I went ahead and completed the "idle relearn" steps just for the heck of it and got a final RPM of 675 (no change). The next day my mileage went up from 20 MPG to 27 MPG in mixed driving (2008 ES350). Thanks for the clear instructions on this!
Great video. I watch this channel for my wife's 2010 venza. My son's 2009 hyundai developed a nasty tick and running rough. But no CEL. I tried everything I could to diagnose on my own but unsuccessful. I was at the point ready to take it to the mechanic. Yesterday I was poking around again and took the air cleaner off to see a dirty throttle body. I recalled this video and proceeded to clean it with seafoam spray and a cloth. Then we did the seafoam procedure of spraying the throttle body while running also into the vacuum line off the brake booster. Let it "hot sit" for 5 minutes then took it on the highway to burn it off. The CEL lit up but I figured the cleaning was a little shock to the system and the computer was relearning how to run. I cleared the CEL by taking off the battery cable for 10 minutes. Now the tick is gone and running perfect and smooth and excellent throttle response.
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.
@@oOgy172 No sir. I had purposely taken the positive battery cable before beginning the "tune-up" because I wanted to clean the battery posts AND allow some of the adaptives to relearn... The Highlander fired right up, settled right down, runs great! MUCH improved throttle tip-in, eliminated a tiny little hesitation.
@@MexicanNYAmerican I personally can vouch for the safety and efficiency of CRC brand THROTTLE BODY CLEANER. It's readily available at retailers or online at a good price
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.
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
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).
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!
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.
Oh - a reminder that this applies only to the Toyota family of vehicles. I was once the unfortunate owner of a 1985 turbo Volvo. The Volvo system resulted in oil mist being inhaled ahead of the turbo (not a defect, just a characteristic of the design). Every October the engine would start once, then die, then start and keep running. The Volvo gurus clued me in to the massive glop in the throttle body and Idle Air Control Valve and, just as they said, it took half a can of throttle body cleaner to clean it all out and get it running reliably for the season - or until there was another failure. I like my Toyotas _much_ better!
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.
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! 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!
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.
@@LuisDC21 I do my own basic maintenance and am very keen in terms of subtle changes in performance related items like whenever I change oil, brakes or in this case clean the throttle body - so the short answer is yes I did .
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.
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.
I'm glad I found this video. The first one I found showed a couple of guys doing exactly what you say not to do: turning the ignition on and having one guy press the gas pedal to open the throttle.
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.
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.
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.
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
I might trade in my Hondas to Toyotas just to be able to work on them. I found your channel a few episodes ago and it's the best channel I have subscribed to. I watch because of the knowledge you have and share in your videos. Stay safe and well
Very clear and simple instructions are you a auto shop teacher thank you for teaching us that we can do preventative maintenance correctly cleaning the throttle your self saved about 85.00 God bless you my brother in Christ aloha
This is so true I have a two thousand eight Toyota Alphard and it has the 2azfe engine. It used to idle very low and even cut off. After my mechanic cleaned my throttle body it went back to normal
Ex Lexus tech here, what I used to do after cleaning the throttle body and disconnecting the battery is start the car let it warm up a bit then put on my parking brake and put it in drive. The parking brake would “hold” the car in place and the idle would relearn and adjust faster
this might be an issue with the 5.7 L engines...parking brake doesn't hold these monsters in drive. I had parking brakes checked and double checked by dealer and have been told over and over again that my parking brake is within the specs. Hi torque engines ...do not try this technique in your garage when a few inches from the wall
I have a 2009 Vibe with the 1.8 engine. On truly cold starts (like the car has sat overnight) the car will start right up - no problems. If it has only been sitting an hour or two though, the car will struggle to start. I don't have to keep cranking, but it will stumble and falter until it really catches, and then will smooth out and behave normally. During that stumble and struggle I will hear the VVTI gear rattle just very briefly. On normal starts I do not hear it at all. Possible suspects: 1) dirty throttle body 2) Mass Air Filter sensor 3) fuel pump 4) VVTI gear 5) Spark plugs / coils 6) clogged fuel injectors. Any other ideas? I'd appreciate anyone's opinion and advice on how to diagnose for certain.
@careover A note to anyone reading the, “parking brake in drive” comment ; be aware if you do this if parking brake fails for any reason, your car will drive away by itself, Potentially killing someone or damaging property.
I have been a mechanic for many years and I still love watching his videos because you learn something from him every time you watch one of his videos.
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.
Thanks for sharing your expertise and your knowledge. I've been watching you for years and I enjoy your content. I bought a 2010 camry for my ex wife and because of your channel I have been able to diagnose and resolve issues with the engine. Thank you for what you do. It's very helpful.
Excellent throttle body video. Do not disconnect battery and/or ECM fuses. Just clean with the proper cleaner via a clothe and let dry for a bit before assembling things back.
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!!
I have cleaned the throttle body on my Honda CR-V, it’s completely different. Thanks for this presentation, it showed me the proper way on my wife’s 2017 RAV4. Jim
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!
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.
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
First thing I did after watching this video was print out the diagram of "Under The Hood" Fuse box, identify which is the ECTS fuse, mark it, just in case. I also placed a printed copy of the description of each fuse inside the fuse box. Now to roll up my sleeves & clean the throttle body.
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.
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!
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!
So glad you did this. Ive always been shows to spray DIRECTLY into the throttle body. Let it sit.. then wipe it. Based on what you showed me. This makes much more sense.
You are so helpful. I have. 2006 Taco, 2.7 L 4 cylinder manual. When in the dealership recently, mechanic/sales rep, not following diagnostic tree for the p0012, code, replacing vvti gear instead of the vvt valve eventually replacing the vvt valve, but showed me they had cleaned throttle body. There was no reason to clean it, as was cleaned a year ago, and since they did this work there is a vibration and rpms off and not back to normal, the vibration increasing as the rpms fall to 600 (shouldnt fall below 800). I went to parts dept to see about replacing the Idle air control valve and learned it it rivited to the throttle body and can't sImply replce the IACV, wondering if they spayed the cleaner into the throttle body onto the IACS, instead of gently wiping the TB clean as you just demonstrated. So to replace the IACS, must buy a new TB costing over $400 just for the part. Difficult to find a dealership I can trust, but heading back tomorrow, to discuss this problem once again. Better learn to do as much mechanical work as I can, or looks like ill have to learn to litigate.
Cant state how much of a blessing this channel is for us being Toyota owners. Do you have any tips on how to clean the engine bay? I'm a nervous wreck wanting to do it...
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!
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! 😁❤️
Yesterday I temporarily removed the battery terminal on the RAV4 III 3ZR-FAE. Idling engine speeds for about half an hour during stops were very low. Today I removed the terminal again and washed the throttle. Idle engine speed is immediately normal. Thanks!
I've got a 2012 Toyota Corolla with about 115K miles on it. It has been well taken care of over the years by the previous owner, they changed the oil and such impeccably, had everything done on time, etc. As of the past couple of years, the downstream O2 sensor started testing only 1 or 2 out of the total of 4 readiness tests on OBD2, flipping between 1 and 2 out of 4 total tests for it and basically just halfway testing and untesting. I've checked voltage on the wiring, changed the O2 sensor 3 times in 2 years (Toyota-branded Denso made no difference vs aftermarket), had the battery tested, etc. When the ECU is reset completely, virtually all tests are complete the next day. It requires overnight testing for the Evap, but everything else tests very rapidly, including both readiness tests for the upstrem engine-side O2 sensor. The catalyst also isn't testing, which I suspect is because of the downstream O2 sensor (before the catalyst) not testing first. What could cause this? There is no check engine light, no error codes in the scanner or anything to indicate that anything is wrong. What am I missing? OBD2 device also shows the voltage of the downstream O2 sensor is registering and also it is reading the catalyst temperature properly. Toyota recommended cleaning the throttle body, but that doesn't seem to be related to the downstream O2 sensor that we're having issues with. It's simply jumping back and forth between 2 of 4 readiness tests completed, then back to 1 of 4, then back to 2 of 4 and just says they haven't been completed yet. We've driven it hundreds of miles after reset.
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.
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.
Thank you for sharing this story.
Interesting how a simple bit of maintenance made all this difference. 🎉❤🎉
9😅w😅o 😊😢
Thanks for sharing your experience,You're right the gasket thingi also is very important I used to undermining the importance. Thanks
Exactly the pump gas has so much trash in it this is where it originates from so yeah you have to do it pretty often I do mine about every 10000 miles
I stopped using kn filter because it makes the MAF error and actually didn't improve airflow as soon as I put in a cheap filter it ran better 😁
Sorry to hear about your dad passed, RIP, our prayers for you and your family.
Thank you for all your help
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.
These dealers are either incompetent , thieves or both. I hate dealers.
That must be one clean throttle plate! Well done!
Never go to the stealer lol
Yea they probably would of just cleaned it and said they switched it with a new one
@@OFFICIALBROTHERBOLDLYMUSICTV That's because their Mothers...
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.
Your 3/36,000 miles complementary service only covers oil change and tire rotations nothing else.
you probably hadn't even changed the air filter yet in that Rav4 and you wanted throttle cleaning? Completely not necessary :)
But, its good that you care about your vehicle!
Can I do same on the newer Toyotas
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.
I am right there with you on brand loyalty. Save the planet and your money. Buy a well maintained used Toyota and take care of it and have a car for 20 years with little hassle.

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

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.
Update: I can now do drum and disk brakes.
Buy yourself a 4 way lug wrench, it makes changing a flat tire so much easier.
Buy a cordless impact wrench with maximum torque in the neighborhood of 150 ft-lb. It will be light and small to maneuver. Yet, it will be capable to take off 95% of the bolts on your car including the wheel lugnuts. I am a home mechanic and it made working on my car fast and enjoyable. I live in US and my impact wrench is made by Bosch model BOSCH GDX18V-1860CN 18V
Good for you and anyone learning maintenance and repair. You can't get a better teacher than Ahmed.
My best advice is to upgrade to a 3 ton jack even if you have a small car.
A 2 ton jack can be unstable if the floor is not level. Also, the jack equipped with your car is for roadside emergency only, like a flat tire. Be careful and use wheel chocks.
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. 😉👍
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!!!
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.
I agree, to have the experience of a Toyota Master Tech explaining in great detail how to perform repairs, maintenance, and what to watch out for is very valuable information and real world experience. I think a donation is a nice thanks to Ahmed. I am a recent subscriber and donator and I look forward to more videos.

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....
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”

This guy is the greatest Toyota mechanic. I’ve learned so much about my 4Runner watching his videos
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.
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!
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.
They make it seem like if you move it, it’ll be a death sentence for your engine lol
Did you move it with your hand and clean?
@@sumanravichandran9107 follow Car Care Nut , he’s a Toyota technician and shows exactly how to do it.
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 was just quoted $300 for a throttle body cleaning at my dealership 🤔
@@liudizzle depends. Do you have multiple throttle bodies? And do they have to come out? Maybe $300 is justified
@@Sci-Mon1no
You must work for the stealer
Only takes 10 mins to clean it and no cost at all just a shop towel and throttle cleaner. They making bank charging $300 for that
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.
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.
Thank you. Your channel is an invaluable asset to the car care community.
I couldn't believe how easy it was to clean my Throttle Body Plate on my 2019 Toyota Highlander. Thank you Sir.
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!!
I have a 2ar-fe in my scion and I feel that pain about getting to the throttle body 😂
I'm currently a Saab owner, but have done some work on my daughter's 2003 Camry. That thing was NEE-glected! She was scared when I mentioned cleaning the throttle body, but very happy after.
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.
as usual, your explanation and reasons why you don't do certain things are second to none... keep sharing your knowledge, pal.... you are teaching me every day... thank you
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.
The best Toyota channel
Glad I found this. Based on watching a few other videos on this topic, it was clear to me that I was not to manipulate the butterfly by hand and that I would need to perform a "relearn idle" procedure afterwards. Instead I intended to turn on the ignition and then have someone depress the throttle (or mechanically hold it open). After watching your video I felt comfortable manually manipulating the butterfly, at least on Toyota/Lexus cars. (I also cleaned the MAF sensor .)
Anyway, the first part of the "relearn idle" procedure is warm the car up. On startup, the idle was about 1900 RPM. At the conclusion of my warm-up drive of 5 to 6 minutes the idle was down to 675, which seemed spot on. I went ahead and completed the "idle relearn" steps just for the heck of it and got a final RPM of 675 (no change).
The next day my mileage went up from 20 MPG to 27 MPG in mixed driving (2008 ES350).
Thanks for the clear instructions on this!
Great video. I watch this channel for my wife's 2010 venza. My son's 2009 hyundai developed a nasty tick and running rough. But no CEL. I tried everything I could to diagnose on my own but unsuccessful. I was at the point ready to take it to the mechanic. Yesterday I was poking around again and took the air cleaner off to see a dirty throttle body. I recalled this video and proceeded to clean it with seafoam spray and a cloth. Then we did the seafoam procedure of spraying the throttle body while running also into the vacuum line off the brake booster. Let it "hot sit" for 5 minutes then took it on the highway to burn it off. The CEL lit up but I figured the cleaning was a little shock to the system and the computer was relearning how to run. I cleared the CEL by taking off the battery cable for 10 minutes. Now the tick is gone and running perfect and smooth and excellent throttle response.
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.
did you have to do a idle relearn procedure after or anything related to the ecu after cleaning?
@@oOgy172 No sir. I had purposely taken the positive battery cable before beginning the "tune-up" because I wanted to clean the battery posts AND allow some of the adaptives to relearn... The Highlander fired right up, settled right down, runs great! MUCH improved throttle tip-in, eliminated a tiny little hesitation.
Would you use WD40 branded throttle body cleaner? I was thinking of getting that to use because it is much cheaper on Amazon
@@MexicanNYAmerican I personally can vouch for the safety and efficiency of CRC brand THROTTLE BODY CLEANER. It's readily available at retailers or online at a good price
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.
So did you clean it & did it solve your issue?
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
does it make a difference on acceleration or just idle?
@@BillSW i did it yesterday in my corolla 2010...both idle and acceleration became very smooth, hesitation gone 🤝✌️
@@baijujohny2415 thanks for responding!
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).
Just did my throttle body no more rough idle at cold start and sometime stall when engine cold. Runs like butter now power improvement.
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!
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.
Oh - a reminder that this applies only to the Toyota family of vehicles. I was once the unfortunate owner of a 1985 turbo Volvo. The Volvo system resulted in oil mist being inhaled ahead of the turbo (not a defect, just a characteristic of the design). Every October the engine would start once, then die, then start and keep running. The Volvo gurus clued me in to the massive glop in the throttle body and Idle Air Control Valve and, just as they said, it took half a can of throttle body cleaner to clean it all out and get it running reliably for the season - or until there was another failure. I like my Toyotas _much_ better!
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.
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.
You can use a silicone lubricant made for rubber to help you with that
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
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!
Other videos show that process as well so it's very confusing and conflicting.
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.
Did you notice any improvement?
@@LuisDC21 I do my own basic maintenance and am very keen in terms of subtle changes in performance related items like whenever I change oil, brakes or in this case clean the throttle body - so the short answer is yes I did .
Did you change the gasket after cleaning the throttle body?
Did you lube up the Johnson rod?
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.
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.
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!!
OMG. Every time I see your videos I learn more and more. I feel like I'm becoming a real mechanic 😂
You deserve an award for making great content. Thank You. I'm ready to clean my throttle body on a 2003 Lexus IS300.
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.
I'm glad I found this video. The first one I found showed a couple of guys doing exactly what you say not to do: turning the ignition on and having one guy press the gas pedal to open the throttle.
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.
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.

This is so true I have a two thousand eight Toyota Alphard and it has the 2azfe engine. It used to idle very low and even cut off. After my mechanic cleaned my throttle body it went back to normal
Ex Lexus tech here, what I used to do after cleaning the throttle body and disconnecting the battery is start the car let it warm up a bit then put on my parking brake and put it in drive. The parking brake would “hold” the car in place and the idle would relearn and adjust faster
this might be an issue with the 5.7 L engines...parking brake doesn't hold these monsters in drive. I had parking brakes checked and double checked by dealer and have been told over and over again that my parking brake is within the specs. Hi torque engines ...do not try this technique in your garage when a few inches from the wall
I had to run my car holding brake to do same.
you can use cleaning tips with spray on em for the edge area
I have a 2009 Vibe with the 1.8 engine. On truly cold starts (like the car has sat overnight) the car will start right up - no problems. If it has only been sitting an hour or two though, the car will struggle to start. I don't have to keep cranking, but it will stumble and falter until it really catches, and then will smooth out and behave normally. During that stumble and struggle I will hear the VVTI gear rattle just very briefly. On normal starts I do not hear it at all. Possible suspects: 1) dirty throttle body 2) Mass Air Filter sensor 3) fuel pump 4) VVTI gear 5) Spark plugs / coils 6) clogged fuel injectors. Any other ideas?
I'd appreciate anyone's opinion and advice on how to diagnose for certain.

Now to roll up my sleeves & clean the throttle body.
best video out of 50 others I have watch on cleaning throttle body. Now I'm ready to do mine tomorrow :) thank you
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.
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. 😊
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!
This channel should be required viewing for any Toyota tech or diyer. Invaluable information from this guy. Keep the content coming!
My sentiments!
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!
Interesting. Much less expensive. Thanks for posting.
You make very good videos and make it very clear... thank you
Priceless video! The best channel on youtube!
So glad you did this. Ive always been shows to spray DIRECTLY into the throttle body. Let it sit.. then wipe it. Based on what you showed me. This makes much more sense.
You are so helpful. I have. 2006 Taco, 2.7 L 4 cylinder manual. When in the dealership recently, mechanic/sales rep, not following diagnostic tree for the p0012, code, replacing vvti gear instead of the vvt valve eventually replacing the vvt valve, but showed me they had cleaned throttle body. There was no reason to clean it, as was cleaned a year ago, and since they did this work there is a vibration and rpms off and not back to normal, the vibration increasing as the rpms fall to 600 (shouldnt fall below 800). I went to parts dept to see about replacing the Idle air control valve and learned it it rivited to the throttle body and can't sImply replce the IACV, wondering if they spayed the cleaner into the throttle body onto the IACS, instead of gently wiping the TB clean as you just demonstrated. So to replace the IACS, must buy a new TB costing over $400 just for the part. Difficult to find a dealership I can trust, but heading back tomorrow, to discuss this problem once again. Better learn to do as much mechanical work as I can, or looks like ill have to learn to litigate.
Cant state how much of a blessing this channel is for us being Toyota owners. Do you have any tips on how to clean the engine bay? I'm a nervous wreck wanting to do it...
Hi! I would use a spray bottle with soap and water spray it then use compressed air to dry things up then wipe it down
@@TheCarCareNut thank you for that
All questions that I had in beginning of video are answered to the end of it. Thank you AMD!
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!
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! 😁❤️
Yesterday I temporarily removed the battery terminal on the RAV4 III 3ZR-FAE. Idling engine speeds for about half an hour during stops were very low. Today I removed the terminal again and washed the throttle. Idle engine speed is immediately normal. Thanks!

It has been well taken care of over the years by the previous owner, they changed the oil and such impeccably, had everything done on time, etc. As of the past couple of years, the downstream O2 sensor started testing only 1 or 2 out of the total of 4 readiness tests on OBD2, flipping between 1 and 2 out of 4 total tests for it and basically just halfway testing and untesting. I've checked voltage on the wiring, changed the O2 sensor 3 times in 2 years (Toyota-branded Denso made no difference vs aftermarket), had the battery tested, etc. When the ECU is reset completely, virtually all tests are complete the next day. It requires overnight testing for the Evap, but everything else tests very rapidly, including both readiness tests for the upstrem engine-side O2 sensor. The catalyst also isn't testing, which I suspect is because of the downstream O2 sensor (before the catalyst) not testing first.
What could cause this? There is no check engine light, no error codes in the scanner or anything to indicate that anything is wrong. What am I missing? OBD2 device also shows the voltage of the downstream O2 sensor is registering and also it is reading the catalyst temperature properly. Toyota recommended cleaning the throttle body, but that doesn't seem to be related to the downstream O2 sensor that we're having issues with. It's simply jumping back and forth between 2 of 4 readiness tests completed, then back to 1 of 4, then back to 2 of 4 and just says they haven't been completed yet. We've driven it hundreds of miles after reset.
