Cleaning an ELECTRONIC Throttle Body: Toyota Throttle Body CLEANING / REPLACE: 2002 - 2008 Corolla
HTML-код
- Опубликовано: 19 июл 2024
- This video covers cleaning an electronic throttle body, specifically the Toyota Corolla throttle body on the 2002 - 2008 Corolla. To replace an electronic throttle body, or if you are considering how to replace throttle body (Toyota Corolla years 2005 - 2008) or how to clean electronic throttle body or how to clean a drive by wire throttle body, there are certain steps that should be taken to do this safely and prevent potential damage to the electronic motor or position sensor.
This tune up item is a necessary step especially if you are having bad throttle body symptoms which include poor gas mileage, rough idling, weak acceleration etc. Throttle body related codes P2107, P2108, P2111, P2112, P2118 and P2119 may be easily repaired by cleaning the throttle body, except if parts are damaged or there's a short in the circuit.
This how to clean an electronic throttle body video also specifically covers other Toyota with the 1ZZFE engine and not just the 2002, 2003, 2004, 2005, 2006, 2007 and 2008 Toyota Corolla.

More informative than 95% of the videos out there, thank you so much!!!
Thanks a lot for the compliment and for taking the time to comment!
Agreed! That part about the idle reset with battery disconnect was so valuable, thanks!
I agree!
I've watched so many videos on this topic and this is by far the best
Worked wonderfully for my 07 corolla. Efficient video. My car was idling so low it would die at stop signs after I changed the starter out, it runs smooth now. Thanks for the much needed and appreciated direction!
Thanks for sharing!
Did you replace the starter or do what he did in the video?
God bless you because my 2006 corolla was giving me problem and I believe it is the throttle body 🤦🏽♀️
Thanks. All the best!
I did that and for my surprise it made a huge difference. Before cleaning rpm where 300 and engine was shaking. After cleaning rpm went up to 800 rpm. 🤓👍
😃 Always good to hear when things work. Thanks for sharing!
Thank you boss.
My car is petrol & LPG gas my Throttle body is blocked.
This video is a life saver ❤
Thank you
Glad it helped!
Thank you sir for your knowledge. This helped me big time. It's not that difficult really. You made it so easu.
Thanks. Glad you found it useful!!!
This was the perfect amount of information, clearly explained. Thank you so much!

Excellent thorough explanation. Well done. Thank you
You are welcome!
thank you. out of all the videos yours helped me the most. i appreciate you!
Glad it helped!
Thanks done engine runs well for first time in a long time.
That's nice! I'm grinning from here😁
Very good video; thanks; you cover all the bases !!
Thanks mate!
Fantastic tutorial well done 👍
Thanks!
Thanks for the great tutorial.
Many thanks!!!
Very informative, good job !!
Thanks!
Thank you very much bro.....I save a 40$ to do it by my self
More power to you!
Great content sir 👍🏼
You could also do a video on how to clean the fuel injectors and cylinders on this car without having to dissemble the engine. The type of cleaning where you just use the pressure cleaners that you hang on the hood of your car, and the borescope to check the amount of build up in the cylinders.
Have a good one sir, one love ✊🏾🇳🇬
Thanks!
This suggestion or a similar variation has been on my mind for months. Just crack it out soon. Thanks upping this.
@@DIYAutoworksNG you’re welcome sir
Thanks for the helpful tip 👍
You're welcome.
Hmm, I nearly didn't watch til the end cos it's not my car. I just wanted new tips on the actual cleaning. Glad I did since I learned about the whole resetting malarkey. Wont be able to remember all that so wiil save. Thank you!!
Glad you find it helpful. Thanks for watching!
Nice-one ! maybe clean the sensor up by the air-cleaner too (MAF) ? Dave NZ
Thanks. Sure, already did the MAF as well as the PCV valve on this engine
Great job my friend 👏
Thanks, 🤛🏼
Nice work and good Ilustration
Thanks
Explicación completa muchas gracias brother.
Gracias!
Nice and easy job
Yes, thanks
Exactly the same as the toyota aygo throttle body. It's amazing how you go into detail. I will be changing it soon. Hopefully, nothing goes wrong 😂
Thanks for the compliment. Good luck and all the best!
Thank you so much, I bought a used car almost a year ago, and the acceleration is weird. For example, if I'm coming from a full stop and I press on the gas pedal, it will go then significantly slow down, and it takes maybe 10-15 sec to start accelerating properly. And no mechanic has been able to tell me what it is. Thank God for you and RUclips 😭
Happy for you!
Super good.
Thanks!
That’s a giants toothbrush 😂 great video cheers 🍻
😅😅😅😅 This cracked me up. Thanks for the compliment!
Great Video done by a normal mechanic. Love the use of the dot punch 😊
Gonna clean my wife's Auris throttle body after our holiday.
Did my Scooby Legacy 1 month after buying it 2nd hand with 90,000 miles on the clock.
My God, it was gunked full of Carbon. Not anymore👍
Thanks! Carbon is the enemy😂
How was your holiday & how did you go?
Thank you sir 🙏
You're welcome. 👍🏼👍🏼👍🏼
Teşekkürler hocam thanks
Rica ederim!
All the best Piyke :))
Thanks mate!
Merci
You're welcome
I used this method once on the vehicle with engine running and air intake hose off, spraying CRC Throttle Body Cleaner into the air intake. Black crud came out of the exhaust.
And you felt quite satisfied I would imagine😁. Never observed my exhaust while using a spray cleaner. I will definitely setup this shot one day.
One problem doing it that way is you could bugger up the Cat and or Lambda Sensors. Better to clean it while the car is off.
@@BandiMasha
I think it did crud up the catalytic, very mildly though.
I put in new Cats though for better flow.
Performance is like comparing night and day now. Vehicle is way more responsive on acceleration.
@@BandiMasha Not only the car is off but also the ign key is out.
in video at 5:33 on throttle body top right cornar there is a screw hidden in a glue type material.
can you please tell me, what is the function of that. and how it help in adjusting a specific parameter?
I have observed that changing the position of that screw make throttal pedal response to respond differently and effect the drivability .
I have an issue of poor idling. throttle body is cleaned. every possibility has been checked but could not fix the issue.
Hey, I wasn't able to see the the screw you were talking about. However, I'd say a number of other things can cause a rough idle. Do you have a check engine light? Any codes?
How many pounds on the torque?
I have a question, does this throttle body reset itself?
I will service my 2005 Toyota Matrix Xr
And I want to know if this throttle body can be reprogrammed by itself
no need for a scanner
You don't need a scanner for the idle relearn, but there is an idle relearn procedure. Which you should do if you moved the butterfly plate by hand or took it out of vehicle to clean as I did. Here it is:
Warm up the car. Shut it off.
Put the key in the ignition.
Turn the key to the On position, but don't start the engine. Wait a few seconds, turn it off.
Repeat the above step again. But instead of turning off, start the engine.
Engage the parking brake.
Set the gear in Drive.
Wait 5-10 mins.
Shut off the car.
@@DIYAutoworksNG Just one detail that I forgot to add, my Matrix is manual transmission
It's the same process, but do I have to put it in first gear?
@@DIYAutoworksNG And thank you very much for your help.
Golf tees work well to plug coolant lines
Thanks!!!
@@DIYAutoworksNG Thank YOU !!
Golf tees work for vacuum lines but are too small for those coolant lines !!
You should open the valve and remove the dirt on valve edge and the area valve touchs while it is closed.
This can be done after remounting using the gas pedal to depress the butterfly plate. Although aggressive blasting usually melts it off.
Will this procedure correlate with the 2021 corolla hybrid?
Good question. It would appear so, however, there are general safety measures for working on hybrid vehicles which have the capacity to deliver fatal electric shocks. Because I haven't really worked on hybrids, I'd say you do a bit more digging for TB cleaning on hybrid cars.
My corolla 2007/2008 has the same part and i bought a valvule iac to replace but i could not find, so this has one or not??? I have no idea :(
Your Corolla is drive by wire meaning it does not have an IACV. So in summary, it does not have.
How to know if the butterfly is damaged
Does a 2006 corrolla has a iac valve
Just take a look at the throttle body. If it has black cables running into it with locking nuts, it does. If it doesn't it has no IACV.
Warning ⚠️ Carb cleaner can be much more harsh on this engine component. You should only use THROTTLE BODY CLEANER 👍🏻
100% correct you are. I now have and use throttle body cleaner.
Is best the carb clener and need clean the intake for a good job
Could this process, apply to the 1azfe engine throttle body?
I haven't worked on the 1azfe, but the principle is the same.
@@DIYAutoworksNG thanks
Is this good for when my car cant idle and just dies? It starts up and drives normally, but dies when I stop the car.
This could be one of the causes. They are many. Needs troubleshooting to narrow down.
Could a dirty throttle body causes the vehicle to have low idle and shuts off?
Yep
Can you do this without removing the throttle body? Just sprang and wiping? I'm afraid to break seals on those old hoses
You can, though the back side of the butterfly plate will be difficult to clean.
Genuine concern there on old hoses. I cleaned the PCV valve on this same car recently, and the hose to it had become hard and simply cracked while I was trying to fit it back 😠. Had to make a dash to pick up the hose and refit.
How would you know if you’re low on coolant?
The coolant reservoir will be below the low mark.
Can a dirty throttle body cause car to idle too high when started? Takes a couple mins and then goes down or goes down once put into reverse…
It's possible. Could be a vacuum leak too. Also, depending on the car, could also be vehicle in need of an idle relearn procedure. Do let me know the cause when you finally get it. All the best. 👍🏼
@@DIYAutoworksNG Thanks man!! I absolutely loved this video, so thorough. It’s a 2005 Toyota Corolla. So I could do the procedure you did after cleaning? I’m gonna clean it next week when the weather breaks for my son. Thank you for such a quick response, what state are you in?
I have toyota corolla 2010. can you please mention the default throttle plate opening at idle by manufacturer? unfortunately the mechanic has messed up with the L-key screw on throttle body. now throttle plate opening at idle is not at orignal position. Thanks in advance.
Isn't the throttle body on the 2010 Corolla electronic? I can't exactly relate to manual adjustment of idle on the car using a screw.
I recommend should changing your mechanic. Gone are the days of adjusting idle from the throttle body. The ECU controls everything with input from several sensors.
Except I'm missing something, it's rather an idle relearn or throttle body reset procedure that should apply.
@@DIYAutoworksNG in the video at 5:30 see the top right corner, there is a yellowish glue type material, if u remove that, the L-key screw is there. in my case this screw has been messed up with. now I want to bring it back to orignal position. I need your help in this regard. also if u have any service manual of throttle body..
I see. Unfortunately, I really don't have experience with adjusting electronic throttle bodies manually.
Man , that engine looks like needs a full cleaning job ...
Yea 😂.
Rusty yup
Good day please when i engage my car on drive the car will use force to enter gear and the engine is high what do i do is censor throttle please thank you sir
You'll need to scan the car to get a better picture of the problem. Are you able to do that?
🤣
Why some people pushing their Toyota throttle body butterfly (fly by wire)
Better not to push by hand or at least minimise it.
@@DIYAutoworksNG may I know why ?
Do you mean why it's not good to push by hand?
@@DIYAutoworksNG yes,
It's because drive by wire uses a motor to control the butterfly plate as against the spring mechanism used in drive by cable. Pushing the butterfly plate by hand can distort the caliberation of the motor, could also have the risk of stripping gears if not done correctly and lastly, if the vehicle is powered, because the butterfly plate is motor controlled, it could catch anything in its part and bite down with intense force. E.g. chop off a finger if it gets caught.
Was that car in a flood? Why is the whole thing covered with mud?
Not a flooded car. Some years back it was used consistently on muddy terrain and not washed.
First disconect the hoses and conectors.
I prefer doing it the other way round for having the bolts for plugs for the hoses.
Please since i service my throat body my RPM is higher
That will normally happen. You need to do the idle relearn procedure for the car
Wasteful way of cleaning! Just use a rug with the liquid cleaner
Not sure I get this. What rug?
Totally unnecessary !🤨
Cleaning the throttle body or taking it out to clean?
