Take off you throttle body (TB) held by the 4 bolts. There is no need to take off the coolant lines or to unplug the TB wiring harness. Unplugging the harness will simply interfere with your ECU's idle procedure and the ECU will take some take some re-adjust itself. Turn the key to the on position but DON'T crank the engine, have someone or something press the accelerator pedal all the way to the floor and the throttle plate will open to its fullest so you can clean inside the throttle body. As you are there, take out the MAP sensor, (the 1KR-FE 3 cylinder engine does not have a MAF sensor) use either electronic parts cleaner or MAF sensor cleaner, allow to dry and re-install. This is a common recurring procedure I perform at regular intervals with the 1KR-FE engine. Too much back pressure causes oil smear on the MAP sensor and carbon deposits inside the throttle body. However, regular cleaning will have your engine running normal and you will have far less vibration and reducing the risk of the engine stalling out. Cheers!
Hey
I have a question, if I took those connectors (I have done that before reading this comment) is there anything I can do to fix floating idle rpm? (It goes up and down 1-2k rpm). I did drove it around 50km and it's better (now it cranks to 3k rpm instead first time at 5.5k) however this idle stays the same.
@@BOTmaster15 You may have to perform idle relearn procedure

Would it be the same procedure dealing with a maf sensor for the 2szfe 1.3 for vitz
Hello are you familiar with the issue of cold starts in the morning? On the first attemp it sounds like the starter is stuck..but when you switch off and start again the car starts just fine.
Are u mechanic ? No right ? So they are doing their work right
The throttle body also does have air orifices which are dedicated to supply engine with air while the throttle is shut and the engine idles. Remove also clog deposits off which prevent sufficient air intake while idling causing vibration. The throttle itself acts while accelerator cranked and engine revs, but while idling- air orifices facilitate air suck into the engine.
Worth cleaning your PCV while under there,it's so overlooked & forgotten about....very important to do.
You are genius, just because if you I saved my car otherwise I was about to get rid of it 😂
Well done 👏
Thanks
Fantastic video..❤
superb 😘
Should or could have cleaned maf behind throttle body whilst doing that but greatvideo thanks
How many times should this be done in a year?
Good
Sir have Toyota Avanza here after top overhaul the engine is shaking the rpm is going down and up I heard some clicking noise in throttle body
Nice videoo
Apki locatin kya ha?
Can't one change throttle body sensor on this engine? Seems like it's hard attached to the throttle
Also disconnect body wire off the battery before disconnecting wire harness off the throttle body.
Is the Toyota Yaris 2011 Terra Sporty engine belted or chained?
Belt
Seeing it drive by wire was there any problem after start up idling problems
Where can I find u
I have done that but the same
I I have Toyota Yaris 2007 my engine so much vibration
location?
Lahore

Dear, why you didn’t clean the IAC valve, must be having lot of carbon deposits. 🤔
It's supposed to be a diy, so I tried my best to do just enough to solve the problem without complicating it
Italian
Two weeks later the Vibration will come
Bro where is this mechanic?
Do you have a question?
@@houserepairs4766 hi sir how are you?
