Exactly I've seen videos of talk talk talk and never talk about what the video was supposed to be about.
Thanks for the video! You went more in depth than some of the other videos here. Using your method I found what seems like a dead/worn spot on my tps during the transition from idle position to wot. At about 25 - 35% from idle, measuring voltage only instead of the smooth progression of increasing value, it dropped down and then shot back up continuing like it should. I experienced this during my driving but never knew what caused the problem, it felt like I would lose power at a certain point during my acceleration but at cruising speed it would be ok. I replaced the tps and I don't have that issue anymore, again, thank you for the great video. It helps when things get pointed out and then I can test it for myself to find the problem. Mahalos!
Just saw this in 2024. Thank you for this superb teaching video. I am grateful. At 67 years old, I now think I understand how the throttle position sensor works, thanks to you.
So glad I found this video! Thank you! My intuition told me throttle position sensor initially, but advice from others was possible cma shaft sensor, Pulled codes that confirmed throttle positions sensor but not sure I can trust as this car was used when I bought it with a rebuilt hyped up racing motor. The wiring is sketchy. With that being said, having this knowledge lets me trouble shoot before buying the part! Car idles very rough when cold, and idle will increase then decrease on it's own. Slight acceleration issues as it doesn't immediately respond to pedal pressure. Runs better when warm. Idles great at higher speed. It does need exhaust running from the headers and back. These are racing headers so I'm unsure how much vacuum pressure plays a role. I have spark, but no start. In my research a no start is rare but possible. Any thoughts from others is graciously accepted :) Aware it could be timing, but want to start at the easiest point and work my way to that.
I find your videos are some of the most informative without getting overly technical with information that we don't really need to know. This helped me diagnose my tps and move on to find the real problem. Thanks brother
I second that.
What I really appreciate about your video is that you gave clear & easy instructions on how to use the DVOM & for the 1st time I totally understand how to use it for testing my TPS! Thank you 🙏🏽 sir!!!
I second that.
Thank you The diagnostic procedure of the throttle position sensor is exactly what I need to know. Discovered that my TPS was outputting 4 1/2 Volts at idle ,closed throttle plate . Thank you again.
I just wanted you to know that you are an awesome person and thanks for taking the time to do this. Very easy and really good explanation on how and when to do the work. Have a great day and God bless you
I second that.
I really enjoy work on cars and have been learning a lot with your videos. thanks for sharing your knowledge amigo
Yes, very instructive and well filmed and well explained. Thank you.
Yes 🙌🏽
I knew something was wrong with the TPS but wasn't sure. If I hadn't of seen your tutorial then I would've purchased one off of ebay without being sure that was my problem. Thanks a lot for your help, your video was very informative.
i dont know why therr are 61 thumbs down but thats most likely why the people who put thunbs down are not running.this is a great peice of advice even a. woman can understand it... thats me...great utube guys 50 thumbs up.x
One word: Competitors, though you could make it 2 by adding jealous. But you are absolutely right and this guy makes some the best videos out there.
Some people are just never happy. they just have to have something bad to say.
Susan King absolutely your so rite, this guy is the best electrical guy on the internet, I totally agree, no thumbs down for this guy
Unless someone is straight up giving harmful information why would someone thumbs down it. Lol. I have a “competing” channel that is small but growing and I have people trashing me too at times. Thankfully the vast majority are good people and trying to learn. I look at it as we are all on the same team. We are all looking for automotive knowledge. Haters Gonna Hate though! Haha. Good video man!
Like me, I found this is a great video and easy for me to fix my own throttle body work ,instead of having someone else do it. Plus I'll be saving money doing it myself...
Your guidance is crystal clear and easy to follow. Nice job!
I second that.
Dude thanks a lot for this video. I have the "Circuit low input" code coming up on my GMC Sierra. This enabled me to check everything and put in a new throttle position sensor as well as repair a wire in an O'Reilly's auto-parts parking lot! These types of posts save people a lot of money. Thanks again!cheers bro
I second that.
Great video! It's always nice when someone takes the time to explain a job so well. Thank you.
I second that.
Ratchets and Wrenches I find is one of the Better auto repair sites on RUclips 👍👍👍
I just wanted to thank you bro you're a badass I want you to know that I work on cars I'm used a multimeter but you're playing spoken explanation with excellent in my understanding of the tool has increased exponentially thank you again
i live in the Caribbean, been learning alot from your videos. Great job! i wish i can migrate and work along side you, you seem to have so much to offer when it comes to dealing with vehicles
This is gold and this man has skills on explaining. Thank you....p.s. I took notes.
InstaBlaster...
Looks like a GM ? If I'm correct! I've done this so many times on my Toyota hilux ( Tacoma) but Aussie version! I'm glad you are around! Thanks heaps and cheers from Australia 🙂👍👍👍
Thank you very much, it was very informative, easy to follow along and to the point. Mostly find RUclips to bore me with talking to much or hard to follow
People giving this a thumbs down have no business even opening the hood. GREAT, simple, informative video!
Best shown i have seen on youtube. Now its all clear thanks!
I second that.
😊 I've watched a few of these tests. Yours is number one. Top of the list 😁
Absolutely fantastic video. Clear, concise, and easily understood. Thank you!
I second that.
I second that.
Now to testing ! I have a 1994 F53 460 / 7.5 engine in a motor home, and it has given me so much trouble ! Trying not to throw parts at it! I have had it running well, then it just does not want to get up and go! If I didn't like the motor home and I didn't like the 460, I would walk away and sell it! Thanks, Rick
I am so glad I found this Igrbetslly search Old jeep issues. Zip cannot thank you enough for explaining everything so thoroughly. I was stumped with why I had crank but no comms no nothing. I did finally find my TPS was like cracked open.
I have the new connector and Tps but my existing wire is a small gage the new connector wiring is at least double thickness.
So I decided to see if I could find if it anyone else ran into this?
Thank-you! Good and clear lesson. I know what to do!
Great video, it help me fix my sensor today.
Voltage when up and down on the idle so installed a new throttle position sensor and all is great now.
great clear explanation, thanks for the professional advice ...👏🏻👏🏻👏🏻
Thank you, very informative and to the point.
thanks for taking the time to help others. you explain everything very well. ive seen some of your videos in the past & there spot on. thanks again & keep them coming your the first person i go to when i need help.
I second that.
Excellent work, you would make a good shop teacher.
That was the best and most informative video I have seen so far in my quest in my situation. THANKS
Great video, exactly the info I needed
Great video! Looks like the TPS isn't my problem. The search continues 😅
Great video. Clear and straight to the point. Thanks!!!
I second that.
Great Demo! I'm on my way to get a multi-meter right now.
Roderic Fields they are a must for any serious DIY'er. thanks for watching. cheers
Thanks for the help video was clear into the point I really appreciate it I got it running
Yeah.. mine failed big time when I tapped on it. Thanks for helping win the fight on figuring out my headache. Now I can sleep with one eye open. R32 gtr was a popcorn machine
Great video. Simple and clear.
Great video. Simple and clear. Thanks man.
Frederick Garcia np, thanks for watching.
Great, you cover all I need to know to check my vehicle, Thank you so much,
Great video....well spoken and to the point! Thanks.
Great video! I love the way you placed the pin into the connector. Couldn't you have placed the ground probe into the negative battery post? Or would that not be as accurate? I love your video. Thanks!!!
I learn a lot from your videos. Great instruction thanks.
I second that.
Did you strip the wire when you connected the aligator clip?? is the car was it on position while you turning the cable??
you cant get a better explination, great job..#1
Thanks Homes! I'm gonna go try this right now!
Great explanation! Thanks for the video.
I am a diy guy. Very very good thank you so much. Take care stay well
I have a 1996 Volvo 850T5 that stalled after code P0120. Almost got rear ended by a Mack Truck on the NJ turnpike! I changed the TPS twice. I also thought maybe the ECU was defective, so I changed that also.I cleaned the Throttle body with throttle body cleaner.. It seems that after about 25 miles the car stalls, I clear the code and then it runs for another 25 miles, until it stalls again and the code comes back. Thank you for your great Videos.
You are so informative you put Scotty Kilmer to shame. He spends too much time bashing GM and FCA. Maybe he thinks it makes him a hero.
good video lots of information unlike all these videos with nothing.
Thanks so much for posting! Instructions were clear and helpful!
Nice video. Thanks! I have a 4-wire sensor though and don't want to mess up my computer by poking around with my digital meter.
This guy is really good.
Thanks for the video. Its been so useful.
thank you so much, this cleared a lot of confusion for me and i was able to test TPS on my motorcycle.
Nice work in probing for the signal lead and how to differentiate the supply voltage.
Hey, Andrew! Do you understand this? I got 5.10 V on the first and 4.42 V on the middle. About 2.2 V for ground. Now what?
Yes clear, easy to follow, no non stop jabbering.
I tested the harness like you did. I am finding that the signal pin is also showing 5v like the supply voltage. Is this normal? Trying to figure out where I went wrong, or if this is by design for my particular tps harness. I have 2001 mazda protege 2.0L
I know this is way old but I’m seeing the exact same thing on a 91 dodge dakota. Did you figure that out?
All of your videos are awesome, I have learnt a lot from your videos. The RPM is jumping up and down a little while cruising at high speed, 75-80 MPH, could the TPS or transmission be the problem? I just clean the TPS and it looks super clean, but RPM is still jumping. Thanks
What leads you to believe it could be transmission? Maybe cam shaft sensor?
Thank you master for sharing your knowledge
Thanks for your video. It helped solve my problem.
Thank you very much for sharing. The video and instructions very clear.
My 1993 F 150 started idling way to high ( no tach but probably 1400RPM ). I unplugged the TPS and the idle went to normal. I drove it around the block with it unhooked and it actually drove ok with it disconnected (?!). I take it that I need to replace the TPS but it seems crazy that it idles and accelerates pretty decent with it not hooked up.
Bout go outside and give this number a try. Just got a 950$ s10 and I personally believe these “hard shifts” are more along the lines of something fuel related, I can feel a misfire a very small one, I believe it’s the tps but I’m not no expert. Plus the truck is too old for my code reader. Giving u a like just for being cool. Hope I can figure something out without effing anything up haha
I agree good job , and thanks for taking the time to post it.
Thanks for the help. This may just save me a chunk of change!
Valuable information for bigginers
Thank you for the video!
Thanks for the help info.
Thanks boss for d nice video!. Now i can apply this process to my nissan sentra GA15dne😊
Always clear and informative
I replaced a TPS recently on a Ford Freestar. The closed throttle position on does not line up with the TPS. Turning it in order to install it seems like it would cause a problem.
thanks, clear and concise explanation
very useful video.
can u please mention the procedure for toyota corolla 2010 model with electronic throttle body without accelrator cable.
Nice
Haa! Painter and mechanic. Wow you’re a bit of a car expert. Good for you
Great video. I cleaned my tps and tried to put it back in the correct way it came out but sometimes when I mash I get hesitation. What can I do ? I've tried different positions but didn't seem to work. Can you give some advise on this thanks
Your videos are great
Very informative video
Great Video
Check the throttle body to see if there is a gap. If there is a big gap, that can be caused by carbon or wear. It can cause high idle and codes. Replace it if it's worn. It may can throw codes about the TPS. Set the sensor for mid-range of specs.
What do you mean gap? Gap in between throttle body and motor?
You are great sir
this video is much appreciated!
Great video. Thank you.
You set the Multimeter to Resistance / Continuity to determine which wire is Ground. Therefore I take it that you cannot set the Multimeter to DC Volts to find the ground wire by connecting the red lead to the +ve battery terminal and using the -ve lead to find which of the 2 remaining wires is Ground ( I would expect to see 12V on the M/meter when finding the ground wire). I am curious to know if you can find the ground wire this way or not and if not, why? Or is Resistance / Continuity the only way to find the ground wire. Appreciate any feedback.
You could do that, I just went with resistance so that you can also see the resistance reading of your grounding wire. Its also a little quicker since you dont have to switch the test lead on your battery :)
Great, thanks for taking the time to do this video. It was very helpful :)

What brand and model of camera do you use my friend? Really crystal clear video.
Good how to video. No obnoxious audio and
great video! my TPS voltage is sitting at 2.9, open throttle slowly and rises to 5.0. release throttle and back to 2.9. think this means bad tps?? again, great video, first time I've ever tested voltage on a sensor or anything like this. went great
could you use a test light connected to negative of the battery and back probe each wire and see which is ground and swap the test light to positive of the battery to find out the feed wire.Using multimeter you could back probe each wire on back of the connector with out disconnect seeing where is ground,power feed,and signal wire.You did a good video keeping going.
Thank you bro for the info you explain everything very well :)
Great video...like your style...straight and to the point! I have a '91 Camaro with an LS1 engine. It has a new throttle body with new IAC & TPS. PCM threw a P0122 code which is low TPS voltage which should be around 0.5v-1v at idle up to 5v at WOT. Voltmeter read 0.13v at idle (which explains the code) and only 3.94v at WOT. Since the TB was new, the manufacturer sent me a new TPS under warranty. When tested, it was perfect...just under 1v at idle and 4.95v at WOT. A day later, the new TPS was back to the same range (0.13v at idle & 3.94v at WOT) which threw the same code P0122. Any ideas as to what could cause this voltage drop? FYI, this is a newly swapped engine. I am at a point of "crank, no start" and am troubleshooting that as well. I do have voltage at injectors and coils, spark and 58psi of fuel at the rail. Thank you!
thank you for the video
Nice job !!
Very good video,helped me out. Thanks
Excellent video. very helpful. Thanks!
Great info! Is this something you can also see using live data on your new Autel 708?
Great vid❤️
