HYUNDAI NO THROTTLE CONTROL

THIS WAS A 2011 HYUNDAI SONATA WITH NO THROTTLE RESPONSE .
HAD CODES P2101
P2106
P2110
P2135
P0121
P0221
ALL THROTTLE POSITION RELATED CODES AND FORCED IDLE/LIMP HOME MODE CODES
ENDED UP FIXING IT WITH A USED THROTTLE BODY

[@wysetech2000]

Awesome diagnosis and repair. I had a similar problem on some Cadillac junk a few months ago and after doubting myself I decided that the testing results were out of spec and after I believed and replaced the throttle body the problem was cured.

[@TheDisgruntledMechanic]

I am glad I am not the only one that got confused by that throttle pedal position sensor. Had a friend that had one of these and had to try and figure all that out and I know much less about it than you. His Hyundai was same year and most of same codes as you got. Thanks for the video.

[@jamesdanner7850]

+The Disgruntled Mechanic yea. In hindsight, I think it was the snap - on scan tools description of the codes more than Mitchells . .. did a throttle body fix yours as well?

[@TheDisgruntledMechanic]

my Autel described it the same way. The throttle body was replaced before I ever looked at it. What the guy who replaced it did was actually peel back/cut the wires to do his checks rather than back probing. We fixed the wiring that was cut and that helped but did not fix it. As soon as I saw the taped wires to the TPS I went directly to those. There is some other Danner guy on youtube that says to never trust where you know other people were and you see tape.The owner got the shits of it traded it in.

[@jamesdanner7850]

Ha. My brother the other

[@TheDisgruntledMechanic]

yea I knew he is your brother. I have met him before.

[@ChrisTexas]

I just checked the other day if you had posted any new videos that I had missed. Always glad to see your content. Keep up the excellent work.

[@johnhopkins8164]

Mr Danner, love your videos. I watch them between your brothers videos. Love to see your kids too. Reminds me of of my grandkids. They may be be pests, but you got to love them!

[@woppini]

Great video as usual. Love the shop comedy that goes along with it. Great family you have btw. Just picked up a lightly used Solus Ultra and still messing with the functions. Now I know what the lock icon does! Each car I spend a bit more time with to see what the tool is capable of

[@sonsautomotive]

thanks again for an awesome video and for taking the mystery out of electronic throttle body scan tool data! and the problem with the trans could be the torque converter is being partially applied...if the trans cooler is plugged up it will apply....again thank you for the great video!!!

[@sonsautomotive]

sorry it took so long to respond....i have seen this in hyundai..always seemed to need to go to the tranny shop....also there is a video from motoYam82 that is titled hyundai unintended acceleration...that video will show you why the dealer would not do the tbi without fixing the transmission....again thanks for the video!

[@TrimJazz]

so much for a 100k powertrain warranty..... james is back!

[@anyway_anyway]

YOU AND YOUR BROTHER ARE THE BEST I'VE SEEN...

[@pedrolriveranegron5178]

Greattins from Puerto Rico James!!!Your children are grown! Since the lasts videos at the beach and "Grammy's Junk Camry" Great God bless them!!! Great video to...

[@jamesdanner7850]

+pedro l rivera negron tell me about it!. My first. .Cora, is driving and I gotta pray on the passenger side. Ha.. kidding.. she does well. AND.. no more diapers

[@pedrolriveranegron5178]

Jaaaaaaaa!!!! Cora got her license or she's been practicing? I refer to the "Little gentleman" and the "little blonde lady" on the video!!! like I told you on the "beach vacation" video! " I feel very proud of you, for giving "NEW HOPE" to that "little boy" CONGRATULATIONS FOR YOU, YOUR WIFE AND HIS BROTHERS!!! GREAT...

[@rrmech11]

Hello James. Glad to see a new video.

[@mbarry9737]

Cute kids. Did you perform a reset procedure after installing the used TB? It needs to find home again - same thing when throttle bodies are cleaned: "Without starting the engine, turn the ignition ON (Turn the ignition key to ON position or press the Start-Stop Button two times without depressing the brake pedal) for at least 10 seconds and then turn OFF for at least 10 seconds. This procedure allows the ECM to automatically learn the throttle valve position. The following Throttle Position Learning Enable Conditions must exist for learning to take place: Battery voltage > 10V - Engine coolant temperature > 41.5F (5.3C)" Generally best starting point is stack APP & TBS % PIDs and test drive, as you were doing later on, and look for something that doesn't belong. Good vid's JD - like the concise editing. :-)

[@jamesdanner7850]

+M Barry thanks. I did not do that relearn. I kinda disconnected the battery overnight for that tranny issue to no avail. But the throttle seemed to work right

[@Mikesky10]

James Danner actually hyundai does not need any relearn procedure for the throtle body; great video!!!!

[@SteveRobReviews]

Nice vid buddy , that was a little over my head , keep at it Danner . Cheers

[@trainer2018]

Good job James. So did you and Nick find anything else out about the Transmission?

[@jamesdanner7850]

+busjockey1 no. The searching I did some had valve body issues. Kinda fits. It would be OK at initial stop then progressively get worse the longer I set at a stop. Maybe a valve seeping ? If u Google it ,a lot of those lame forums with no answers had a lot of the same complaints

[@trainer2018]

Get any scan data of the Trans for your Input Turbine Speed and output speed? Do you have a Pressure Transducer for your Vantage so you could check the Main Pressure? Just some thoughts. Kind of curious what the issue is.

[@michaelherbert8213]

When is Nick gonna start making videos? How do you like your solus ultra? Great video my friend.

[@blackericdenice]

I was just talking about how you put me to sleep. I see you still do. 2:15 was all I could handle.

[@jamesdanner7850]

+blackericdenice it's probably healthier than taking a pill to sleep

[@blackericdenice]

James Danner Yes you are and I don't wake up with a bad taste n my mouth.

[@jamesdanner7850]

+blackericdenice ha

[@camelotboxers1]

i have a 2004 hyundai Setanta fe 3.5 with code p2127 something to do with the throttle switch e low input ,didnt no if you every heard of this problem, picked the car up at the exhaust shop noticed veh was losing power ,check egine came on code 2127 ,today the veh is running fine fine ,was going to clear the code and see if it occurs again, didnt no if you every heard of any none history problems with these veh ,sry to bother you great video ,you seem to no alot about computers much thanks

[@jamesdanner7850]

+Joshua Larson I'll check Monday when I'm back at work. But I think those have an accelerator pedal position sensor near or under the master cylinder

[@camelotboxers1]

thanks james any input would be great ,i appreciate you taking the time to look into it for me ,i cleared the code ,it started to act up again, the check engine light came back on ,kinda acts like thrre a rev limiter, as soon as you step on the brake it would stall out ,check the engine code still the same a p2127 ,i checked the throttle plates they were dirty cleaned them by having a friend turn the key on and floor the pedle so the plates would open so i could clean ,i did see the switch near the master cylinder you mentioned has about 9 wires coming out of it ,checked the throttle plate actuator controler on the side of the throttle plate housing, connection seem ok ,i did notice when i was going to clean the plates the plates seem like they were sticking when my friend was flooring the pedle, didnt seem as bad when i cleaned the plate, i cleared the code ,the light came right back on but ran better /normal other than the light was back on it seem to run ok ,didnt no if it would be worth it to go to a savage yard and remove the throttle plates houseing assembly, and the throttle switch under the master and cross my fingers, Thanks again for your help !

[@jamesdanner7850]

+Joshua Larson the code is for r the accelerator pedal sensor . Not the throttle position. If u have graphing meter u can check signal and powers.grounds. but if not. Get the part under the master cylinder from the salvage yard if it's cheap. Let me know if u want to test anything, I can look thru the diagram.

[@camelotboxers1]

Many thanks james ,iam going to try to find one today at my local salvage yard ,ill keep you posted and let you no how i make out ,have a good one thanks a million! !

[@jamesdanner7850]

+Joshua Larson not sure if you are in the US but if so car-part.com is a site all the salvage yards list on. U can sort by distance from a zip code

[@NICDOE819]

When you replace components Hyundai or kia on the GDI motor there is an a/t value reset. when you had the battery disconnected that should have done it.

[@Turbotomass]

despite your throttle signal voltages being in spec. Your saying the throttle body is bad because the angle data pid isn't changing or reaching close to 100% despite manually moving it 100%? I thought the voltage was the raw data non substituted value. And the angle was a calculated number. Angle data false because of the error or substituted?????

[@jamesdanner7850]

+Turbotomass I didn't move to 100% while watching. It was the difference in the throttle angle percentages. Which would be calculated from the live voltages. And since the used one worked correctly just plugging it in, the raw data had to be off.. if I had more time I could have screen shotted the graphed signal from the first tbody to the second one during the commanded test and checked for the difference in peaks. I think it's all in the vid. Just didn't go that far. I'll have to watch it again and see if it's all there

[@rhkips]

Did the trans issue show up after the throttle body was replaced, or was it there before?

[@jamesdanner7850]

+rhkips it was there before. I didn't drive it much because of the forced idle issue but nick felt it pulling hard when trying to park it . And the dealer said it needed a transmission and a throttle body at a cost of 2700 before it came back to me

[@rhkips]

James Danner Alright, that rules out a throttle relearn issue then. Bugger. Knowing Hyundai's dealership procedures for such things, my recommendation would be to send it to a transmission specialist. My gut reaction is that the transmission itself is physically fine (for now), and that there's a control issue, but without being able to prod at it myself, I really can't speculate beyond that. :[

[@JOHNPHUFNAGEL]

Hey jimmy great video!! I will be off work the week of the 4Th you mind if I stop by at your shop to meet you and hang out for a few

[@jamesdanner7850]

+JOHN HUFNAGEL yea. Cool shoot me a text whenever so I can make sure it's a good day for hangin

[@JOHNPHUFNAGEL]

+James Danner thanks I will. My daughter thinks it awesome that I know a famous you tuber. I also asked Paul but he hasn't responded yet

[@ScannerDanner]

that was going to be my suggestion, to meet at Danner's shop. I just got home from our "out west" vacation

[@JOHNPHUFNAGEL]

+ScannerDanner awesome thanks thanks so much. I will let jim know what day. 😃

[@JOHNPHUFNAGEL]

Be carful putting your scanner on the windshield, just ask Scanner Danner what happens..

[@IntradeMotors]

i know gdi suffer the same as diesel from extreme sludging egr problems. Long live service and wrong oil is the biggest problem. Fix is induction cleaning from BG they have a machine and the additives for that problem. just to add what i know of direct injection part.

[@jamesdanner7850]

+Intrade Motor haven't messed with any yet except a vw. At the rear of cams where the little timing chain fails , has a part that drives the pump

[@johnmckamy6398]

Yeah new video,

[@johnmckamy6398]

I think after half throttle it goes beyond 7.6% and turns the check engine light on.

[@MCHNCTCH]

Couldn't you have disconnected the battery, reset KAM, and then rechecked TPS %. Just a thought.

[@jamesdanner7850]

+M3CH4N1CT3CH I started wondering that half way through but with it leaving and potential warranty, I didn't try it. Then with a cheap used one available, we just ordered it when we knew it was coming back. The fact that it just plugged in and worked without any resets makes me think that it isn't an adaptive type system. Just fixed parameters. But I still should have tried it to eliminate the possibility. Great question. Sorry I can't answer it with 100% confidence. Thanks

[@NCPDFSB]

james i know hiram gutierrez is a genius on transmission driveability issues. hes always happy to respond to technicians. you can find him on google plus "hiram gutierrez". hes a true asset to the automotive community... like yourself.

[@jamesdanner7850]

+NCPDFSB didn't know of him. I'll have to check it out. Thanks for the compliment as well

[@rwbishop]

Be careful sticking your fingers in those drive by wire throttle bodies... they can really bite.

[@jamesdanner7850]

+rwbishop yes! I've had one force close with my hand in it. Can't remember the car or scenario but u are correct

[@haywardsautomotive6156]

Nice diagnosis & video James. So your brother is the one hitting the dislike button :-)
