I can conclude this video saved me a ton of time.
Nice
Likewise
I must admit that you're really a professional engineer 🤝. I love your video but especially the way you explain things to the understanding of even a novice.
Thank you so much for sharing your knowledge!
I AM really pleased with this info. During this video we could confirm correct function of every single variable resistor within the throttle itself. Thanks Greetings from Caracas ,Venezuela.
Thank you! That is the best, easiest and most thorough explanation on YT. Found my problem IMMEDIATELY.
This man is a master.
Absolutely fantastic work. Helped me confirm that my throttle body was defective. Cannot thank you enough. Test was performed on a 2013 Chevy Silverado WT 6cyl 4.3L. Test 4 was higher Ohms as in some other cases below. My throttle failed Test 1 & 2. Initially had passed Test 1. Also had Ohm breaks in Test 2 where it went to OL briefly. Didn't see your throttle do that when pressing down on butterfly. Tried to run test again to verify and then it failed Test 1 completely. Yes, I verified the leads were in the correct position and did another test to be triple sure. Went straight to OL both times. A million thanks. Let me know if you guys want me to post my video results to see what it looked like in the comments. Bravo!!
Thanks for the video. Gonna do this tomorrow on my 08 impala. Saves me money not having to go to a shop to have it checked.
The demonstration is so thorough and easy to understand.
Thanks for the info , came in very handy . I did the test just like the way you explained , and found out I had a faulty TPS for an 07 Saturn Relay .
I used your diagnostic method to check a six wire 2009 Chevy Malibu 2.4 L throttle body assembly. You're recommendation to use alligator clips was spot on. Would have been very difficult without them.
I couple of differences with the 4 cyl vehicle. Test 2 & 3 were opposite polarity (i.e. opposite polarity when butterfly was opened or closed) but they seemed to have smooth resistance changes with no jumps. Test 4 the resting resistance was higher, 30 Ohms, but not open (OL) or zero. So i think the concept works on the 2.4 L engine but the system wiring or logic is different for the 4cyl model. Haven't put the car back together but I expect my throttle body is OK now.
Hey I definitely could use your help!! I'm dealing with the 2.4 myself and TB codes.
I used the method in this TH-cam video to rule out the TB. I could be wrong tho. I have a few sensor codes all related to the ECM so I have a new one on order. If that not it it’s either a no spark or no fuel issue. I reconnected all connections using a product called Stabilant 22. It’s supposed to improve bad connections. That didn’t work either.
Truly super explanation rarely found on TH-cam...I wish if you could explain mk3 throttle body for vw someday thanks for sharing
Abraham: I thank the Lord for your knowlege and healt . thatns to this video you recorded, you helped me to fix my 2008 Grnd caravan. i thank ypou too for making the time to share your knowledge. sorry about the typoa, Ii was riding my motorcycles and dropped them on the highway. i can not see well qhT I TYPE. Iwill rewrite this message as soon as I can get my new glases. i had tu use a magnifier glass when I tested my throtle body on the van. Yhaks a million!
I agree with the previous comment. Excellent video with perfect instructions and explanations. very easy to follow and thanks for sharing your knowledge. I wish those others would follow your lead.
Thanks for the video! I am working on a marine digital throttle & shift demonstrator for a training aid at the marina where I work. I pulled a GM throttle body out of the warranty pile and with your video can determine if it will work!
Man knowledge like that is priceless ...and a time saver
Very great video. Thanks for the additional labels you made. It really help me get to understand which pins to reach out to for those tests. Thumbs up!!!
your channel really should have more subscribers
❤ uno de los mejores videos explicados de una manera muy sencilla, saludos desde chile y bendiciones
Best help on these units I have seen....Thanks a lot on how to test these!
It is best to use analog multimeters for such measurements. Moving the throttle will show an immediate error in the resistor path. Measurements with an electronic multimeter are subject to errors resulting from the measurement itself. Digital devices simply do not perform linear measurement, but perform so-called sampling from time to time. And this means that a value that changes linearly is not really presented to us linearly. Therefore, it is worth returning to this type of measurements with old linear multimeters.
Apart from that, the presentation is great. Thenks.
I hate to throw parts at a malfunction, and these days when the new part is bad out of the box; thanks for the education.
Very helpful video. Very detailed with photos and most importantly for the blind folks, the connectors pin out photos.
Best video on TH-cam!
Great video 👍 Thanks for taking the time to share and make this available to us. 😃
Thanks for taking the time. Thank you for sharing and make this video available to us. Great video
Exceptionally clear instructions.
Super, super clear! Brain dead clear video. (Perfect for me) 😂
Super clear instructional video. Really helpful. Thank you very much.
For those who are asking if this works on your electronic throttle body the answer is yes. It will have different readings but the procedure is the same.
YOU MADE it easy for us Mechanics ... Can u please tell me how to Diagnose the pins of harness whether if its a motor voltage pin or ground or tps 1 or 2
I like your video. Gonna do it on my 12 Malibu
What a great tutorial 👌. This worked on a 2.4L ecotec 08 Saturn Sky. Last test failed.
What did you get on the last test
@@josemenchaca3944 I had less than 1 ohm on the last test. Watch for defective GM parts... after receiving and installing the new tb I was still having the same problem.
I tried everything from doing an idle relearn to checking all vacuum lines, testing relays and fuses. Finally took it to the dealership to only find out that the new GM part was defective.
My 2006 Sierra 4x4 has the TAC Motor on pins A & C, which measures 1.6 ohm. Surprised there is so much variation between different automobile lines.
Awesome Lesson, Thank you!
Great Video! Thanks!😄
Excellent test for our knowledge
Great testing procedures video,thanks....
Hermano Dios mío muchas gracias excelente test.
Best video ever thanks 👍
Do these methods applied to foreign vehicles,too or every car is different,depending upon the manufacturer? Thanks,great tutorial video...
Make more videos my guy your doing it right
Thank you very much ....its much helpful...
I'll run these tests, but I first checked the 6 pin connector. Yellow and Brown wires go to the throttle motor from the ECM. TAC Motor Control 1 and 2. The other wires are low ref/signal wires, most reading 5v.
I'm only getting 4.43mV and 10.7mV on the Yellow and Brown wires (disconnected, ignition on), but i feel like one should be roughly battery voltage and one should be ground.
I'd just hate to replace the throttle body and still have a problem.
So if any of these four test were to fail, is it safe to say that this component(throttle body) would have to be changed ? Also could you upload a video where your doing this exact test where this component(throttle body) is installed in the vehicle ?
Thanks alot Excellent video !
سلام وسپاس وتشکر بسیار عالی وهزاران 👍....👍....
Gracias por tu información, es para mí de mucha ayuda..
Tq for sharing
Cheers bro. that was super easy to understand. much appreciated.
Thank you for clear information
Thanks for tutorial, there are 6 pins, how do I know which terminals are E and C out of 6 pins please?
Excellent video!!! Would this by chance apply to a throttle body on a Chevrolete Cruz 1.4L Turbo 2014?
Tanks for the video God bless you 😉
Great video! Chevy TPS sensors are known to go bad! This leads me to ask can I test my 2009 Trailblazer ss TPS sensor in the same way.
I know realize it's been some time since you posted this video and replied. But I am DIY'er and really would like to get your guidance on how to perform this very test on my vehicle.
thanks very clear explanation 🖒🖒🖒
Maestro Bravo !
Great tutorial! This throttle body looks very similar to the one on my 2018 GM 5.3L Silverado. Do you think the pinouts and trends you outlined in this video would be similar for my TB?
The test procedure is the same, but the terminals that are checked will be different. At the moment, I don't have the info the give you the updated instructions for your particular application.
Thx for the reply.
Excellent!!
You could really improve the educational experience by overlaying the full circuit and pin out to understand how each test circuit operates.
Where have u been? I have noticed that u have stopped upload videos. Hope everything is ok. Please take the time to upload more videos. Urs is the best. God bless.
excellent video
i have a 1996 a 1996 GMC Sonoma with 2.2 engine the power wire plug going to ignition control module has 2 wires - the plug that should have 6 wires only has 2 wires- is this normal- how do i check it ? trying to get a reply from easy auto diagnostics-thanks
Can I use these same values and measurements for a 2009 Buick Enclave?
Sir I am from Pakistan. Please tell me whether we can test Nissan ad throttle body using this method?
Le metiste los 12v de la baterial o usaste otra pila de otro voltaje?
need information on 2005 corvette throttle body test
I have Chevrolet Aveo 1.4 LS. Is this method suitable for my vehicle?
Thanks
Thanks
multumesc cumetre.
Could you please accurately explain which terminals are where ?
The photo of the terminal block doesn't correlate accurately !
Is terminal "A" at the top left or top right ?
Why don't you show the diagram of the terminal block first before you start ?
Hello ! sir, I am very happy for this video because I have the same problem on Hummer H3 year 2007 engine 3.7 L5 petrol 4x4 I code p2128 the box has 8 threads how to test it?
Mon email c'est : eliekabwemisoko@gmail.com
for the first test, should it be 1.5 ohms or 1500 ohms?
Thanks sir training
What if the TPS2 test is opened loop for the 2 test terminals?
Wish he'd said what was what as in ground, pos , neg on other pinouts as wanted to apply same principal to 2010 Dodge Grand Caravan and see if worked on one I have on bench.
gracias te felicito
Great information
thanks
Thank you very much for the information very useful video, I checked my motor ohm and the reading is 8K ohm, is that mean I need to replace the throttle? My car is Mitsubishi outlander 2009. Waiting for your reply please
My throttle body is reading .10k over is that bad or is there an allowed amount over
How do I relearn throttle body sensor on 07 Malibu 2.2
Per the GM repair manual instructions, this is how to do the 'throttle relearn' (it's actually the idle relearn):
1. Start the engine.
2. Let the engine idle for 3 minutes (in Park).
3. Turn the ignition OFF and leave it off for 1 minute (60 seconds).
4. Repeat steps 1 thru 2.
5. After the second 3 minute idle, the throttle relearn should be complete and the engine should be idling normal.
6. If after all this, the idle speed hasn't been relearned, drive the car at speeds above 44 MPH with several decelerations and extended idles.
7. After this drive cycle, the engine should be idling smoothy.
If the engine idle still has not been learned after the drive cycle. Repeat the entire process.
If engine idle has been relearned, erase any codes that may have been registered.
Thanks Boss you are Great
I have 2010 toyota corolla with electronic throttle body. engine had vibrations at idle. mechanic first clean throttle body with carb cleaner . but did not fix the issue. then he messed up with that idle screw. now the car driveability is more worst, it lack power when accelarate. although engine idle has stable RPM 700.
can you please give me a brief procedure or service manual to bring that screw to its orignal position.
I have requested too many guys on youtube but no body has help me.
Thank you in advance.
Great work, you gotta make some more 👏👏
H2 ,2005years. Vortex engine 6.0L . Throttle connect is same too
Dose this apply to Saab 2004 gm parts right??
I have an Audi Q5 2.0TDI 2010 I found my throttle body 100% open when the engine was off is this normal?
excellent video, can you make some other for subaru TB?...i have a xv with fb20 engine and when i put key in start TB makes a wired noise...think its fali...thank you so much
Hello ;). How to test Chevrolet camaro 2016 3.6 v6 ?
Thank you for posting this. Is it possible that this will also apply to European GM cars - eg Opel Meriva A throttle body?
Good job
My 2005 Tahoe throttle body wire got wet what should l do
Hi there,
Is the E connect to the ground or signal wire to ECM or connect to the 5v?
thanks friend
Hi, really helpful video, I have a Mazda 5 sport 2007, that will not rev over 2000rpm, the connectors on mine are all in a row six pins, would know the correct pin to use, to reproduce your test,, a big thanks if you can help
How about a drawing of the electical connections, a schematic diagram to accompany this video????
Yes.... thank you, I totally agree.
What about Chevrolet HHR 2006? is the same procedure?, thanks
My question is does this apply to other cars say my bmw has the same style plug except its labeled 1-6
The GM part number of this throttle body is: 2173108 (GM Genuine). I checked for you and this throttle body does not fit any BMW.
Even if it looks similar, the internal circuits will be different. Using the test procedure in the video will give you the wrong test results.
What is the year and model of your BMW? I may just be able to find the procedure for it -maybe.
Hi Will This test procedure support Chevrolet spark 2008 throttle body?
Please suggest..
I have a question. My car is a gm Astra 2007. It has a 2.4 liter 4 cylinder 16 valves and a throtle body magneti marelli very.similar that you show in the video. My fail is when the car stays at idle. The car runs perfect but when i press the gas pedal a tinny the car fails like he want to stall out. And when you start at cold in the morning feels like starts in 3 cylinders and at 4 seconds pass to 4 cylinders. I clean the throttle body and te car works better but that issue its make me crazy. The sparks plug are new. People told me change the spark leads. Thank you
