How to clean drive by wire Throttle Body on most KIA Vehicle

You can clean drive by wire throttle body without opening the butterfly valve with the proper cleaning brush. This vehicle experience poor idle and sometimes stalling, I recommend throttle body cleaning and here are the step by step process. NOTE: opening the butterfly valve without unplugging the connector sometimes required calibration.

Thank you very much for your video, very easy to follow. Close views allowed me to understand in details the steps. However I had a bit of panick right after cleaning the throttle body. First time I tried to start the engine it ran for 2 seconds, then stopped. Next try 1 second. Next try did not run at all. I found on forums that it is indeed pretty common when cleaning the throttle body. According to the forum, a trick that often works is to floor it and release the pedal once the engine runs. I did it and it worked. Maybe an improvment for your videos could be a "frequently encountered problem" section at the end. (for dummies like me not to panick 😂)

[@WrenchingRyan]

Mostly after throttle cleaning your engine will experience long crank/rough idle for few seconds. Loved the idea about frequently encountered problems after cleaning. For sure will be added on my next video. Thank you 🙏

Great video! Can you tell why you clean that black circle on the back side? I belive that is a factory thing!

[@annaboyle4896]

The black ring is most likely carbon deposits that's causing the rough idle. If it is something that comes from factory I would look into it to see if its something that needs to be cleaned or shouldn't be but normally factory ones are completely bare metal.

Good Morning! I am having issues with my wife's 2017 Kia Rio LX so I decided to post on here for any suggestions or helpful tips! I am no mechanic however I did a ton of research in hopes to get this problem resolved! Here is the story so far.... 2017 Kia Rio LX V4 Error Code: P0445 fixed P0442 active Problem: Stalls at Idle/stop signs after driving for 30+ Once turned off it can take 2-5 minutes of rest until the car successful turns back on Replaced: Canister Close Valve Purge Valve Gas Cap Crankshaft Sensor Hypothesis / Things not yet replaced or tested: EVAP Vacuum Leak or Clog Vent Solenoid Charcoal Canister Cracked/ Defective Thank you in advance! 2017 Kia Rio LX 1.6 L 4-cylinder

[@WrenchingRyan]

Start the engine and let it stall, if you have fuel pressure gauge check for pressure it should be 50 to 70 psi, if pressure is low culprit might be the fuel pump. Seems like PCSV already replace, check PCSV pin tension if pin tension is good suspect possibly short to ground in control circuit. Good luck.

[@juliangallegos7627]

@@WrenchingRyan thank you so much for your service- I truly appreciate the expert information!!

[@DAK59]

I use a toothbrush. It's smaller and gets in the throttle body easier.

[@WrenchingRyan]

Anything works right.. Thanks for watching.

[@bringforthtruth]

Do you have to replace the gasket? I saw a orange one on the engine.

[@WrenchingRyan]

check the gasket condition, 9 out of 10 you can re used it but if gasket is in bad shape replace it. thanks for watching

[@bobdublin825]

Did you put a new gasket on after cleaning

[@bringforthtruth]

I would ask this too.

[@CollinsH86010]

What’s the socket size to unscrew the bolt?

[@WrenchingRyan]

10mm bud, thanks for watching.

[@JadeNecromancer]

Hi I saw your video, wondering if the issue is the same. As my RPM will dip to around 500rpm and engine vibration is quite significant when I switch my aircon speed to fan 2. When I am on aircon speed fan 3 no issue engine not much vibration. Can this be fix by cleaning the throttle body? Driving a kia k3 (2013)

[@WrenchingRyan]

when the A/C compressor is on basically your adding more load to the engine then RPM will slightly change, you can clean your throttle plate using this simple step, if the issue still exist start checking your engine mount, Kia release service bulletin few years ago for Kia forte excessive vibration when a/c is on, we replaced alternator pulley to fix the concerned. good luck and thanks for watching.

[@taylorsharp212]

Ive got a 2006 kia rio and its is sluggish on acceleration it idles rough. And even worse when the ac is turned on ive got no engine codes and nothing major going on. Do you think this may help my issues with the sluggish acceleration in stop and go traffic.

[@taylorsharp212]

Also what are you using. Surly not break cleaner yeah?

[@WrenchingRyan]

@@taylorsharp212 I’ve fixed so many idle issue by cleaning the throttle plate, it’s not gonna hurt if you give it a try. I’m using BG Throttle Body & Intake Cleaner.

[@nelsonchook]

FOR KIA FORTE 2012 ALSO SAME?

[@WrenchingRyan]

For the most part yes. thanks for watching.

[@Woodygdmax]

I have a 2020 kia telluride is this applicable?

[@WrenchingRyan]

Two different engine but for the most part yes. Watch this link to get idea kzbin.info/www/bejne/eXTIXp-qfLZ9h8ksi=wucAJF8BqW3l6r7X

[@kokryan4549]

After cleaning need to reset anything?

[@WrenchingRyan]

Perform this steps and no program needed. Thanks for watching.

[@trippyextendo8387]

what product did you use

[@WrenchingRyan]

BG product, look it up good stuff for your engine.

[@user-xi1to4ph6s]

How often should be done? I have 2016 KIA Forte. Is there a need to disconnect the negative terminal of the battery?

[@WrenchingRyan]

I personally recommend to clean it every 30k miles, you are welcome to disconnect neg. Battery cable, disconnecting throttle body connector might need programming, most kia don’t. Just follow this steps and you will be fine. Thanks for watching.

[@gmm1904]

Don’t need calibration like in nissan ?

[@WrenchingRyan]

If you follow exactly how I did it no calibration needed, but if you unplug the connector and open the plate calibration might required. Thanks for watching.

[@ozyl8069]

It is not easier to remove it completely and clean it?

[@markovalenzuela3315]

how can you do the relearn without a scanner?

[@WrenchingRyan]

scanner is required to perform relearn but you can try this, remove negative and positive battery cable, touch them together for 3 to 5 minutes. hope this work.

[@moinshek]

No need to disconnect battery ?

[@WrenchingRyan]

I don’t know why disconnecting the negative battery cable did know appear in the video. Please disconnect the negative battery cable before performing this job. Thanks 🙏

[@Itsolivera]

What is the relearning process for a 13 optima 2.4 ? If I clean do I even have to relearn ?

[@WrenchingRyan]

If you clean it the way I did no relearning required, if you decided to disconnect the connector and clean it relearn MIGHT required, by the way scanner is required for relearning process. Thanks for watching.

[@Itsolivera]

Ok cool, thanks! So scanner is needed to reset and relearn? Great thanks for the info @@WrenchingRyan

[@WrenchingRyan]

@@Itsolivera Yes scanner is needed to perform reset/relearn.

[@braverinchrist5973]

Should blow out debris after covering intake

[@WrenchingRyan]

I did blow all debris out before I return vehicle to customer. Thanks for watching.

[@cumshot247]

Should blow out debris BEFORE removing anything...

[@LanceB86]

There's no way you just pulled that thing up out of there without disconnecting something else... I'm trying to pull mine out to get to the backside, but it seems impossible without disconnecting either the radiator hose or some of the wiring harnesses...

[@WrenchingRyan]

You can disconnect the throttle body assembly and clean it thoroughly, I did it this way to avoid possible re programming, this throttle body is driven by wire if you open the plate re programming MIGHT needed. FYI I’ve clean a lot by putting them out but one time I got some idle issue and only way to fix it is relearning it.

[@herbertlisone9047]

the real question is, where do you buy that brush from?lol

[@danpaytas9662]

Dollar tree !

[@justinkashtock333]

Harbor Freight has them.

[@DAK59]

Use a toothbrush. It's smaller and fits better.

[@grimfandangox]

Why didn't you take it out? did you just clean inside the car?

[@WrenchingRyan]

yeah, I just cleaned it inside the car, this throttle body is drive by wire, you can remove it and clean it but there’s possibility of programming needed after cleaning.

[@grimfandangox]

@@WrenchingRyanDoes this throttle require adaptation? I thought it did it automatically.

[@WrenchingRyan]

@@grimfandangox if you do it exactly how I did it no relearning needed. If you disconnect the throttle body connector and open the plate you might need to do relearning.

[@kennedypeele5913]

Hi, could cleaning this fix code P0507?

[@beterbey]

If you move that butterfly valve as you clean it, it's totally screwed up and no way to repair / reset. Not a cheap part either..

[@WrenchingRyan]

💯% agreed 👍

[@WanderingHewitts]

Never heard this before. I moved the butterfly when cleaning it and it didn't seem to have any negative effects. I've driven it for probably 100 miles so far and it seems fine. Fingers crossed.....

[@beterbey]

@@WanderingHewitts If it's an old style cable controlled butterfly valve, no problem. But if it's an electronic controlled one, you should not change valve angle as you clean it. No way to repair, no way to recalibrate, you got to replace it with a new one..

[@WanderingHewitts]

@@beterbey it's the electronic one but the car idles and runs perfect. I did disconnect the battery beforehand and it's not throwing any check engine lights. Maybe I got lucky

[@cumshot247]

Was told if you disconnect battery, it won't affect it as long as you don't aggressively open & close, or let it slam shut.

[@DRDROP-fj4bo]

My 2.4 shudders at red light with brake on and in gear. Cleaned throttle body twice. No improvement. Only does it once it warms up. Thinking i need a GDI service. No telling what the valves look like.

[@WrenchingRyan]

GDI service is not bad idea, before you do that take your vehicle to auto store and have them scan it for free, PCM might store a code to begin with. Also you can check your spark plugs for cracks, worn out engine mounts. Good luck.

[@DRDROP-fj4bo]

@@WrenchingRyan Thanks for reply. Yeah I got a good scanner. Only code i get is very small evap leak occasionally when it runs system check. Performed a smoke test and no leaks under the hood. Tested canister purge valve solenoid and it good.Tested coils every way I can and they check out. Going to replace they got lot of miles on them. Maybe one breaking down when it gets hot.

[@jeffreymeyer8950]

​@@WrenchingRyan Isn't a gdi service just spraying the throttle bottle cleaner directly into intake while car is running at 2k rpms?

[@meaux444]

I want to try this.. and you're literally explaining all of the symptoms with my '15 Soul; super high mileage.

[@charleslambertjr3842]

No need to replace the seal / O-ring I’m guessing / if it was needed, you would’ve shown it getting replaced, correct?

[@miltinhogooglejr8620]

I have a 2015 Kia Forte LX with 385,000 miles on it, and I´ve only cleaned the throttle 3 times now. I know! Shame on me!

[@WrenchingRyan]

Wow… 360,000 mile in it just amazing. I’ve been in Kia dealership and the most Kia engine miles I dealt with is 240,000 mile.

[@miltinhogooglejr8620]

I had to go back to my local Kia Dealership to have the ignition recall taken care of, and they were shocked when they saw my mileage. Thank God I have been blessed with a very good car. @@WrenchingRyan

I have a 09 kia 3.3 sorento with 302 ,000 and a 07 kia 3.5 sorento with 281,000 on it there good motors if taken care of

[@justinkashtock333]

Even taken care of, our 2010 2.4 eats a fair amount of oil at 165k; some people just have better luck or live in areas without a lot of stop and go traffic.
