Thanks for the video! My 08 Scion Xb had a low idle and would stall. Taking the throttle body apart and cleaning it fixed the problem and it is running like a dream now. 👍🏻
Great video. Thanks for taking the time to make this and upload it. Same problem on a 09 xb. Terrible idle and would stall. This video was the ONLY useful video I could find. Watched several others before this but they were not helpful. Thanks 🤙🏻🤙🏻
Thanks for the video, there’s not a whole Lotta stuff on Scion XB‘s so it’s nice to find this stuff out there. you’re Scion XB looks exactly like mine.
Nice video. Just did my 2010 XB throttle body. Runs so much better! Had to watch yours video again to see if there was a clamp on the lower small hose below the electrical plug. Thought I might of drop it. No clamp needed on that vac hose.
My Scion TC had a bad idle.. I sprayed the mass airflow sensor with maf cleaner and it idles great now. two screws and it pops out.. very simple to clean. Buy a can of maf sensor cleaner and spray your sensor, if it doesnt idle better, then go ahead and clean you throttle body.
@@lizard878 On my 06, its a small square box on top of the airbox lid. Right near the clamp at the lid and the rubber boot. There are 2 small phillips head screws. You dont need to unplug it.. Take them out and lift the electronic part out but dont touch it at all. Just spray it with the right cleaner a couple times, it dries quick then put it back together. I think I'll do mine again since you reminded me.
Did mine todayyy i just bought a new throttle from ebay for 50 bukkks ...better to go new if you're taking it off alreadyyy ...took me 30 mins to switch it ...thanks alot for the video ...
Thanks for a great video. I am very new at this so please help. I need to know where the MAF is located and how to clean it. Do you have any videos of this?
If you know where the air filter Box is located it is the 1st sensor on the air duct. It has one plug and two screws very easy to take out very easy to clean with special mass air flow sensor spray at your local parts store hopefully that helps or there's plenty of videos about mass airflow sensors
Awesome video. Going to try this before I put this fuel pump in for giggles. Also, does anyone notice the face at 5:46 on the dust to the left of throttle body? Haha
I just cleaned mine yesterday maf sensor and throttle body on 08 scion xb same as the video installed everything back turned engine and a popping sound with some smoke came out and now my car wont stay on unless i keep the gas pedal i need help please!!
Sorry to hear you're having this issue. Hopefully you did not get the electronics of the throttle body submerged in water. Maybe you can try throttle body relearn sequence for the Scion or try to disconnect your battery. To me it sounds like your throttle body is out of sequence and needs to be relearned
You didnt disconnect the battery first thats why you have pressure of the water pump still on,i did my cleaning too and it always say to disconnect battery before taking off the mass airflow connect or other electrical
Interested in switching out my 2012 xB stock throttle body for a larger aftermarket one for hopefully more gains. Any suggestions as to what brand and or size?
great question brother. I assume the gains your looking for is horsepower ? i dont recommend a larger throttle body. the only gains if any that you will see/ feel is maybe a bit quicker acceleration but you will start to lose some M.P.G. there is no one mod. to do on this car for instant GAINS. either dive all in or leave it stock. the money to dive all in will equal the amount of a faster, better car like a 2006 mustang. hopefully this answers your question and save money but people do whatever they want.
@@supersyx yes more HP Is what I was hoping for so it seem then that this particular mod would be a waste of time from your experience. I already have cold air intake, exhaust, & a header. Any other suggestions for adding a few more ponies without going with a super charger? How about an intercooler kit? Thank you Eighty6 subscribing now. Cheers!
@@TroyVoid What I am trying to say is all The Mods you have added so far only increase horseower by very little. And for this particular car that's not fast to begin with you going to spend a lot of money trying to make this car fast you will be better off Find a faster car to begin with. But if you really want to make this car go faster then it's going to cost you with things like maybe a VTEC engine swap or a speed shop to port and polish your motor and other things like a Turbo I want the baby to intercooler different cams bigger injectors and throttle body. It all depends on how much U trying to spend
Thanks for the comment brother but sorry there's not one particular thing I can tell you to Solve your issue. You might need a mechanic at this point Because They are so many probable causes we don't know where to start. If I have to guess you're either getting lack of air flow or lack of fuel. Probable causes could be air filter, throttle body, catalytic converter, fuel pressure Regulator, fuel injectors, Fuel pump, Clogged muffler, PCV valve, engine timing, etc. Good luck brotha. 86 GOT YO FIX
what YEAR is this Xb...mine is a 2006 ...it looks backwards... my heatshield is in the back.. When I clean Camera parts... I actually pour Naptha into my sonic cleaner. Naptha works great. Make sure anything with paint is not placed in there, because the paint will come right off.
Badass man I dig the video sure did help alot. Question though I got the exact same scion so maybe you can tell me why when I drive and press on the gas pedal my scion actually slows down to like 10 mph. Then itll kick back up randomly. Hitting red lights is a nightmare for me tbh. Please help
I've been told if you take out the electronic throttle body out you have to use a scanner to relearn throttle body position otherwise your car will stall. Any problem of that nature to the ones who took it out ??
That's an excellent question my friend you do not have to take out the electronic throttle body if you are swapping throttle bodies most of the time they automatically will relearn. A scanner is not really needed to relearn cars have a factory relearn sequence just look it up for your car
The throttle position sensor might need recalibration if its removed and reinstalled. It's attached separately to the throttle body on some cars. On the Scions it's built into the throttle body, so you don't need to worry about it.
That's a great question and the answer is I don't know I'm pretty sure it's a vacuum hose. It probably goes to the EGR or somewhere on the intake plenum
@@supersyx I mean the brake pedal feels high and I feel like im far from the pedals all the time so I gotta do this real steep angle with my foot. I end up putting my toe on the edge of the brake, straining my foot. I try to put it more square but it’s hard.
@@newblakestone This issue sounds very strange maybe go have your car looked at by professional I'm guessing you might have an issue with an issue with your break booster
One note, it's probably a good idea to spray and clean the throttle body away from the engine compartment. I'm sure it's not too damaging but it's probably a good practice. Plus it allows you to use the sun to dry stuff off quicker.
Great question but air over time, just look at your air filter. Mostly why throttle bodies get dirty because engines recirculate oil to the top of the motor thru the pcv valve and exhaust fumes thru the egr valve which contains oil. The oil mist find its way to the throttle body butterfly valve and dirty everything up over time . Thanks for the great comment.
4 years later and still helping people. Just used this to do my 2012 Scion xB, super easy job and now runs better than it has in years!
No more check engine light! Thank you for being the only person on UA-cam that can work on a scion🤣💪🤝
Thanks for the video! My 08 Scion Xb had a low idle and would stall. Taking the throttle body apart and cleaning it fixed the problem and it is running like a dream now. 👍🏻
Tysm bro, my 2008 scion xb was idling around 300RPM and would stall out sometimes. This tutorial was super helpful!

Glad to help out brotha thanks for the comment. Did you sonic clean yours?
Hey man. I just had this exact issue with my scion. This cleared it right up. Thanks for the great video!
2011 scion, dealer cleaned it and said the shaking at 500 rpm idle will go away, it hasnt
@@dteh4501 did they really clean it 🤔
@@tecno8335 we ended up replacing it, on that same vein, I have not found consistent workmanship where I live 😒
This video helped me fix my Scion.
Thank you very much sir :)
Absolutely brother, thanks for coming back online and leaving a great comment
You did a wonderful job. It was a very good instructional video! Thank you and GOD bless. JC

Nice Buy bros. depending on how many miles is on your throttle body you will be cleaning it far more than buying a new one every time
Thanks Super6, very helpful video.
Mine on my 2011 Ford Escape is much easier to remove. But thanks for the video I have to do this to my wife's xB.
Thanks for the help.!!
What does the hose on the back of the TB go to the last one you disconnected?
Looks like the exact same removal for my tc I took a peek at the throttle body its super dirty been getting ruff idle ...
I gotta get one of those hose clamp tools.
going to try this on my scion this weekend. is it ok that some of that radiator fluid leaked out like that?
have you ever done the speed sensor on the XB?
Nice. How many miles? I have a 2012 with 217k miles so this is on my list.
It worked thank you for the video
Super glad it worked for you my UA-cam friend
So did this fix the rough idle issue ???

Why did you take off the throttle body could you have cleaned it on the car???thanks brother

That’s what I need Bro 😎
did u have to do a throttle relearn ?

Preciate your comment brother but the water pump is ran by the drive Belt its Not an electric pump.

Cadillac converter?
Can the electronic iac section be removed from the throttle body
Yes but why do you want to remove it
What kind of tools do you need to get this done
Just a basic socket set. 10mm socket and ratchet and flat screwdriver
I've been told if you take out the electronic throttle body out you have to use a scanner to relearn throttle body position otherwise your car will stall. Any problem of that nature to the ones who took it out ??

Recal mostly effects post 2014 for Toyota/ Lexus/ Scion
would this be the same procedure on an xa
95% of the time yes all cars throttle bodies are pretty much the same these days
eighty6 thanks man
Ik this is old but did you burp the Radiator after you did this.
Great question not really I believe I just topped off the fluid but you can definitely take the extra measures to burp the system if needed
where the last hose going on the back of the throtter body
That's a great question and the answer is I don't know I'm pretty sure it's a vacuum hose. It probably goes to the EGR or somewhere on the intake plenum
@@supersyx my old one came wiyh 3 and they send me the one with 4 i close the 4 one in the back and i dont know if affect the car

What size are the bolts on the throttle body?
10 mil I think
Just call the dealer they would be happy to tell you in the parts department.:0)
Its 12mm. I just did it recently
Why does my scion xb 2011 has different throttle body only has 3 hoses connected
They just simply change the design . Just remember the orientation of the hoses and you'll be OK
@@supersyx idk but when i put it back it take so long to crank and start and when i turn off my ac while on a stop the idle fluctuating...🤦🏽♂️
@@jannacino5495 Sounds like you need a new one

Why not take the electronics off to submerge the whole thing?
Good question but it can be very difficult to take off the electronics also I believe there's hardly no carbon buildup on electronic side

At what time frame?
@@supersyx 10:12
