That was more than amazing your explanation is the best..please make more videos diagnosing problems and teaching how different sensors work and how to check them and how the different systems work like stop and start, anti-theft,etc and I have a question..I live in France and I saw a lot of Renault cars have throttle plate in the exhaust just before the silencer I wonder what is it for..
Ahmed Sharif That throttle plate can increase the exhaust back pressure. That way the exhaust gas pressure in the Egr gets higher for better Egr performance!
I am a master technician here at the Jersey shore, USA. I enjoy watching your videos as I use them as refresher courses for myself. Having been in the industry 40 years you tend to forget things you don’t utilize on a day today basis. Thank you for what you do. Keep up the good work. Have you ever thought about bringing your show on the road?
That was great. I'm an electronics engineer and computer scientist and have even built RC Airplane with (PWM) servos and controlled them with microcontrollers, etc., so I understand PWM just fine, but it was super helpful to see the tools you use on a car to figure out what's actually going on. Also your PWM explanation was really clear.
Sir you are Johan Cruyff of diagnostics you are one of the best teacher your teaching technique are so amazing and simple that even person like me which i am not very smart can understand.
Can we have your backstory. How you got started, what exactly you do, did you go to school, tour of your shop, etc. awesome videos. Thanks for the time and knowledge!!
At 1st I was a little annoyed how you over explained PWM & Duty Cycle, but as you continued I realized that you are giving "real world" explicit instruction. I have subscribed to your channel. Thank you!
Varian Styles You've got to understand not all viewers are on the same level. Sometimes I'm repeating myself, but that's the way people remember best. Techs are Visual learners so i try to use real examples. Thanks for Subscribing !
@ 3:40 , reason number 4: If the turbocharger shits itself and spews oil into the inlet manifold the throttle body can close and so prevent the engine from running away and self-destructing. Thank you Dan, excellent video, well explained, big thumbs up!
Dear Dan, thank you so much for your videos. They are phenomenal and you are the best teacher I have come across in my life - believe me I have had many. I myself used to teach math and physics to high school students years ago and knew I was not a good teacher, but did not know why. I quit after five years of teaching. I liked tinkering with machines, love cars, had a degree in EE and fixing stuff is rewarding, so I decided to become a car mechanic. Watching you present your "lessons" really opens my eyes to better see what I lacked as a teacher. It is what you abundantly have - good understanding, broad knowledge, apparently a lot of experience, good teachers who taught you well, and a gift to communicate humbly what you know and do best. That gift is extremely rare! I hope you and your family stay in good health, your business thrives, and you continue to teach us. We are all eyes and ears-:). God bless you!
I gotta say, you are an excellent teacher. Just when I think you might skip something, and lose me, you go right to the next question in my head. Thank you
Good evening all i am audi & vw master technician since 2014 South Africa,i am enjoying Diagnostic Dan, its refreshing all we ve done before.I have my own workshop now. Audwagen Springs in South Africa.Keep up the good work.
Getting the basics right from the start, such as the function of the throttle body on a diesel engine, has serious implications down the line where correct diagnosis is concerned. Pwm is given the complete teardown with some very interesting practical applications, demonstrated. The advantage of using a scope from this and other videos, cannot be overstated. Very informative video and so well presented.
Really really impressed by these videos Dan. Have been in the motor trade for many years, have been on many courses over that time and I really don’t think I have experienced the simplicity of how you explain how automotive systems work before! Really grateful for these videos. Please keep them coming. I’m sure great things will come for you. Very good work.
I am an automotive technician. I already knew how duty cycle works, but I have to say that is one of the best explanations I have ever seen about how it works. I just wish you had come right out and said that duty cycle is not about whether something is open or closed but rather HOW MUCH it’s open or closed. You implied it and the egr valve demonstrated it, but you never actually said it. That’s okay for us techs. We can infer it, but if you want to reach a broader audience you should say it. I think more people will understand it better. Great video though. Keep up the good work. One of the best I’ve ever seen. Some say you’re the best teacher on u tube. From what I’ve seen I’d have to agree. So you missed one detail. Big deal. You’ll get even better I’m sure.
this video also explains how an RC car steering works. the degree of the steering angle is controlled by duty cycles open and closed loops ratio. very good explanation man! thank you very much.
Dan, you are amazing! There’s just one thing I don’t understand and that is, why does anyone ever give your videos a thumbs down! Thanks for sharing your vast knowledge with us, I wish I could come and work alongside you!
it's called being a 'retard' or maybe trolls from another platform who cannot stand someone with integrity,that they feel compelled to drag Dan into the gutter, Fat chance of that happening to be Honest!! there is an old saying; 'YOU CANNOT KEEP A GOOD MAN DOWN' keep up the great work Dan, we all appreciate you, LEGEND 😇
A gentleman named Paul wants your background. Me too!! This video was flippin amazing!! Seeing the part respond first to your rudimentary on/off, and then the fancy Dan machine was really cool. Super and I will watch then rewatch then recommend to others!!
I want to Thank You, your videos have helped this “Old Timer” learn the new stuff and stay relevant. I started out in the mid 70s and tried (unsuccessfully) to retire in 2112. I never learned to use a scope and I got by ok but due to my kids college I’m having to get back in the game as a mobile diagnostic and A/C Tech, I’m going to be rolling in about a week and a half and I’m nervous as hell but your videos are really helping me get up to date. Thank You so much!
Great Video. If you have a volt meter on something and your getting like 8 volts, don't assume you have a voltage drop. Flip the volt meter to duty / Hertz and verify it's not under PCM control. Communication is giving and receiving but a signal is an output to a transistor that acts as a high speed relay. That's how I learned it from scanner Danner. Lol
Now that I am working on these European gems more often, I am reviewing some great videos from guy's who work on them on the regular! Learning from a superb instructor 😉👍👍👍
Loving that explanation. I recently had a 11 Honda Fit with a bad throttle actuator pedal. I was able to use my PWM generator to activate the throttle body. But I messed up and replaced the throttle body first, not trusting myself. I then replaced the pedal and fixed the car. If DD was over my shoulder, I would have fixed it right the first time. Diagnose Bill messed it up again!!😩😩😩
Been watching your videos for about a year, and I must say a big big thank you to you for taking time out of your day to fully explain your thaught process, diagnosis and fixing. Your method of passing on your wealth of expertise to us is amazing.i have learned so much from watching your videos. They always say everyday is a school day , Once again a big thank you to you personally Dan , you are a wonderful teacher. And an amazing man with a wealth of knowledge.
Great video dan, I think alot of techs in the industry need to know about pulse width signals as most of the components in cars are using them; you have very good way of explaining things.
He can make ppl understand both theory of relativity and quantum mechanics within 10 mins just standing there in his workshop, he is brilliant , i love his supercool style.
The smoke in an IC is the secret to why they work and when you let the smoke out of an IC it stops working. As this IC has burnt a hole in it letting it's secret smoke out it stopped working the valve body. LOL. Another great video Dan. Years ago only a electronics techs worked with this type of equipment. Now days that skill is being lost in that field as everything in that area is board replaceable and nobody trouble shoots to component level anymore. But in the automotive world now the auto techs must know more that the electronic techs of today. Funny how things change.
Nice belt professor! 🙂 Another great video! You make it so easy to understand, you've got a real talent! Thank you so much for the videos,I wish you'd post more often but I'll take whatever I can get! 👍👍👍👍👍👍👍👍
Thanks Dan for instructing us on diesel throttle body. Like the look of versus edge is that the built in wiring diagrams u showed, cheers my friend, Sandy
sandy anderson I am subscribed to the gmto helpdesk, they have everything. There are also wiring diagrams in the verus software but they are very basic.
You don’t find many people who are as capable as dan. I would like to know where he is working. I have been laughing how many BMWs seem to be having awkward problems, that others can’t fix. Then you go ahead and show what has gone wrong with ease.
DiagnoseDan One question: PWM according to your explanation, what varies is the on time (duty cycle). So no matter the setting, the frequency stays the same. How do you call when the frequency actually changes? Like for example a GM MAF sensor. Thanks.
I have been selling tools for 34 years. I have worked with some of the best techs in the nation. Rod Flores probablly the best ford driveability guy in the nation. But you my friend are amazing. IVe seen you find things that what ive seen no other shop had the patience to fix, especially on bmws. But get away from that snap on crap and get some more launch and autel stuff. Snap on sucks. I was a top snap on dealer 17 years. They do not take care of there dealers or customers.
Thank you! I learned something new. I knew 2 of the reasons why a modern diesel has a throttle body but the one about smoother shut-down was new to me. Great video.
Hello Dan! While diagnosing a vehicle you teach us about very useful information and theories related to those components. I appreciate your work. Good luck
A bit late to the party, but this is... interesting. Learnt something too. Thank you for putting this video up, you're very good. I can easily follow you even though I've got a hearing problem and have to use hearing aids. There are times when there's a definite echo (especially when you face the camera in the workshop and the sound echoes) but I still can follow. Will recommend this channel most definitely to other guys and girls wanting to know more. And, as usual, eyeballs trumps scopes and testers when it comes to taking a visual inspection at the part(s) either inside or outside.
Your videos are so good! So easy to learn even for a very new technician not familiar with the systems you work on. I love the way you demonstrate everything and your word choice is exactly what you mean which is very refreshing. Thank you for making these videos, Dan!
As far as I know the duty-cycle is the % the actuator is connected to ground. So, i allways connect the scope on the signal wire and the ground. In the video the scope is connected parallel on the actuator. The value you got is not the value given by the constructor. For me the duty cycle is the time showing on the cope tension is 0Volt. Or the time the acuator is connected to ground. This is the typical way used in automotive electronics. Do you agreed Dan? With this method you can regulate power without lost of power. Much better than a regulated resistance like we see on old blower motors. In this case no heating of the resictor and so no power lost. Great video Dan. Thanks.
Awesome video. Thanks for sharing your knowledge with us. So far your the smartest tech I have seen on the internet when it comes to auto diagnostic. Craving for more videos everyday. Thanks
Great video. I always knew no.1 reason for throttle body functions but not 2&3. There a really common fault on audis. I ordered and fitted a new one on a car before only to find out it was also faulty. Then fitted a known good 2nd hand
Netjes Dan.. Héél leerzaam voor mij... Ben al een tijdje uit de Automotive wereld, maar deze uitleg maakt het weer zo ontzettend leuk en interessant om met autotechniek in contact te komen om te zien hoe het heden ten dagen er aan toe gaat. Ongekende interessante materie. Bedankt! Gr. Mike
Great video again Dan! Very interesting explanation of the PWM signal. I know i have PWM fans in my computer but i have never understood what it really means. You are awesome Dan! Thanks alot.
Fantastic video as usual Dan!
South Main Auto Repair, Thanks Eric😉
In my opinion Dan you have a great way of breaking things down into layman's terms. It makes your videos very enjoyable.
That was more than amazing your explanation is the best..please make more videos diagnosing problems and teaching how different sensors work and how to check them and how the different systems work like stop and start, anti-theft,etc and I have a question..I live in France and I saw a lot of Renault cars have throttle plate in the exhaust just before the silencer I wonder what is it for..
Ahmed Sharif That throttle plate can increase the exhaust back pressure. That way the exhaust gas pressure in the Egr gets higher for better Egr performance!
DiagnoseDan thanks for answering my question...I just noticed that my comment is in the wrong place
I am a master technician here at the Jersey shore, USA. I enjoy watching your videos as I use them as refresher courses for myself. Having been in the industry 40 years you tend to forget things you don’t utilize on a day today basis. Thank you for what you do. Keep up the good work. Have you ever thought about bringing your show on the road?
this guy should really appears in automotive textbook. he is so good at teaching
There is absolutely no doubt in my mind that if anyone wants to understand basic electronics this is the channel to go to.
Thanks!😊
That was great. I'm an electronics engineer and computer scientist and have even built RC Airplane with (PWM) servos and controlled them with microcontrollers, etc., so I understand PWM just fine, but it was super helpful to see the tools you use on a car to figure out what's actually going on.

These are the best videos on TH-cam if you really want to no about automotive electronics
John Green Thanks that is a great comment!😁👍
I agree.He sure has a great gift, I love that BMW with the shorted door handle and how it shut down the car!!! Dan is AMAZING
USA here, you are a great teacher. Please keep the videos coming. They are among the very best on the net. Thank you
Thank you for the great comment Joe it's appreciated!👍
Excellent explanation even for me, a electronic technician with 45 years of experience.
Sir you are Johan Cruyff of diagnostics you are one of the best teacher your teaching technique are so amazing and simple that even person like me which i am not very smart can understand.
You do know that Johan is dead don't you😂😂
Can we have your backstory. How you got started, what exactly you do, did you go to school, tour of your shop, etc. awesome videos. Thanks for the time and knowledge!!
Paul Oneel, I will certainly do that one day👍

Thanks Alister, i'm just trying to keep things simple. Life is complicated enough as it is!😉
Great TH-cam name 👍
Who needs college when you’ve got DiagnoseDan..
Another clear and concise diagnosis. Spot on.👍
wardybasher Ha Ha 👨🎓💪👍
Thanks Dan you are amazing, after watching ur videos now I can fix my car by myself.
Greetings from Portugal. Leon (bodgit and leggit) was not lying... You Sir are a genius. I love the detailed explanations. Thanks.
Sabino Berenguer Berenguer Ha ha ha my wife thinks I'm a dumbass 🤣🤣🤣 Thanks for watching and the nice comment. I'll Thank Leon for sending you over👍

Bill Rimmer Wow thanks Bill! I'll do a more personal video for sure!
Wow PWM signal. I like the way you explain and simplify the Pulse width Modulation signal and the duty cycle
It is incredible how you simplify all of these. Thanks a lot.
brane pecenica Nothing is complicated, if you know how it Works!😁

ricardo mendes Thanks!👍
Like your sense of humor and you’re a genius Ness
Dan, I do really appreciate your professional and detail explaining of everything in each video. THANKS!!
These is worthy of a automotive/ science class..
Now that I am working on these European gems more often, I am reviewing some great videos from guy's who work on them on the regular!
Learning from a superb instructor 😉👍👍👍
Wow, it is an excellent video for complete learning of the nature of PWM signal. Thanks indeed,sir.

DAN HOW GOOD YOU ARE TO MAKE DIAGNOSIS SO EASY RESPECT !!!!!!!!!!!!!!!!!! TO YOU
Amazing explanation for throttle body in diesel engine, great Dan!
Very clear explanation along with detailed. I'm loving the videos.
That's great to hear!
👍👍 well done again Dan you need to be teaching the next generation!!
Adam King I'm trying!😉 Since they are on computers 24/7 TH-cam seems to be the way to go😁
Luv diagnosedan. I'm learning auto repair and electrical engineering at the same time! Thanks Dan!
You sir are a very talented and smart. I learn a lot with your videos. Thank you so much.
This is the best explanation I've every heard. You would make an excellent teacher.
Thanks👍
You are a great mechanic and a excellent teacher learn a lot from you keep up the good work
Diagnose Dan FIXED IT again.
Great explanation. Thanks.
Thanks for watching!
Nice belt professor! 🙂 Another great video! You make it so easy to understand, you've got a real talent! Thank you so much for the videos,I wish you'd post more often but I'll take whatever I can get! 👍👍👍👍👍👍👍👍
Nick Nicu Thanks!👍👍👍👍
I think one thumb up is not enough at all, you deserve more.....thanks
Thanks Tarek😊
You are very good at what you do and very easy to understand when explaining. Thank you for your great videos
Thanks Dan for instructing us on diesel throttle body. Like the look of versus edge is that the built in wiring diagrams u showed, cheers my friend, Sandy
sandy anderson,No Sandy used the Verus edge as a tablet, it's connected to wifi. I have a subscription at Hella Gutman it's a online wiring diagram.
DiagnoseDan yes these diagrams look good, good wiring diagrams are always a problem is this the only ones u use cheers sandy
sandy anderson I am subscribed to the gmto helpdesk, they have everything. There are also wiring diagrams in the verus software but they are very basic.
DiagnoseDan cheers Dan I contacted Hella this morning for a 7 day free trial (annual subscription £500 +vat) cheers sandy
sandy anderson let me know what you think about it!
Wow, PWM, amazingly simple yet so effective, thank you. This explains a-lot to me!
You don’t find many people who are as capable as dan. I would like to know where he is working.
I have been laughing how many BMWs seem to be having awkward problems, that others can’t fix. Then you go ahead and show what has gone wrong with ease.
All your video's are great training aids and can always get useful information to learn and grown
That's a great comment! Thanks!👍
Enjoy the way you explain the system
Thanks Steven!
I like how you explain things clearly, thanks Dan
Thank you Steven👍
just discovered your channel , briliantly done ,learnt so much just watching a few of your vids . thankyou for your time .
Thanks George👍
You did it again Dan! Thanks for the PWM class, you're a great teacher.
Moving Up Auto Diagnostics Thanks it's appreciated!😁
DiagnoseDan One question: PWM according to your explanation, what varies is the on time (duty cycle). So no matter the setting, the frequency stays the same. How do you call when the frequency actually changes? Like for example a GM MAF sensor. Thanks.
Great work, DD - just shows that many shops don't have the skills base when it comes to fault tracing wiring runs. 👍🏻
Thanks Dan, I finally understand PWM now.
Learning everyday,that's super delicious 😋. Thanks Dan. My best channel everyday!
great explanation with huge depth of knowledge , i have changed many of them but not known how exactly they work .
Soran Ghafour Now you know👍
i love how you take time to explain every thing in details.
The old videos are my favorite 😂
I have trouble understanding 'electricktrickery' stuff but that was spot on, Dan....Now ....I'm off to change a bulb or two!!
Malcolm Young 🤣🤣🤣🤣 Good luck!
The best explanation i have ever seen thank Dan
I have been selling tools for 34 years. I have worked with some of the best techs in the nation. Rod Flores probablly the best ford driveability guy in the nation. But you my friend are amazing. IVe seen you find things that what ive seen no other shop had the patience to fix, especially on bmws. But get away from that snap on crap and get some more launch and autel stuff. Snap on sucks. I was a top snap on dealer 17 years. They do not take care of there dealers or customers.
You are a very good teacher. Really! You are good at it! Thanks
Wow 52nd Dan your still the man.
Nice tutorial.
Tam your getting slow🤣🤣🤣🤣
Tell me about it Dan.Holiday tomorrow 3 weeks in Crete.Recharge the batteries.
Tam Its hot over There!☀️☀️☀️☀️🌡🌡 Have a great Time!😁
Thank you! I learned something new. I knew 2 of the reasons why a modern diesel has a throttle body but the one about smoother shut-down was new to me. Great video.
Great example of PWM & duty cycle Dan 👍
Simply Diagnostics Thanks Steve!👍
Dan your videos and teaching technique are awesome! Thanks for taking time to make the videos!
Thanks!👍👍
THE BEST video I've ever seen on this subject. Absolutely awesome!
Kevin Lewis Wow Thanks!😁
You are soooooo good! I learn so much from you! Thank you!
Hello Dan! While diagnosing a vehicle you teach us about very useful information and theories related to those components. I appreciate your work. Good luck
A bit late to the party, but this is... interesting.
Learnt something too.
Thank you for putting this video up, you're very good. I can easily follow you even though I've got a hearing problem and have to use hearing aids. There are times when there's a definite echo (especially when you face the camera in the workshop and the sound echoes) but I still can follow.
Will recommend this channel most definitely to other guys and girls wanting to know more.
And, as usual, eyeballs trumps scopes and testers when it comes to taking a visual inspection at the part(s) either inside or outside.
Thank you Dan for such an informative video, I can only hope that most mechanics are using these methods
Great video dan. You are one of the best channels on yt. Keep up the good work!
Oz Mechanics Thank you for the great comment buddy it's appreciated!😀
durr went way above my 76 year olod grey matter .. great video
Your videos are so good! So easy to learn even for a very new technician not familiar with the systems you work on. I love the way you demonstrate everything and your word choice is exactly what you mean which is very refreshing. Thank you for making these videos, Dan!
Wow! Thanks for the great comment! It's appreciated.👍👍
Dan you or the best in what you do and the way you explain the problem and to solve it
Wow this dude is amazing, ur a bank of knowledge.
I've just found your TH-cam channel and it's really helping me out as I'm an apprentice who struggles with his electrical diagnosis! Great content.
I have a 2.0 golf with the same code. This has helped immensely, thanks!
As far as I know the duty-cycle is the % the actuator is connected to ground. So, i allways connect the scope on the signal wire and the ground.
