Love this lecture, it's awesome😍
Thanks for sharing SD❤
Stay Blessed Danner Family❤
Thank you sir , I’m not a mechanic but I had a 1986 Toyota pickup dually with the 4 cylinder 22re engine and now I own another 1986 Toyota motor home and 1987 Toyota dually flatbed with the same type of engine and I watched several videos trying to figure how exactly that opening relay and air flow sensor works and you have made very clear in this class ,this is just a hobby for me but it feels really good to know.
@@Gabriel.A1 awesome! Thanks for the comment
You provide a great service for both entry level mechanics and seasoned technicians who just need a refresher from working flat rate so long. Thank you.
I love these lectures because I can poke a wire and take readings all day long. The technical explanation really does it for me. Theory of operation explained with a wiring diagram is totally awesome. I would love to see more of this content. Scanner Danner is still the greatest technical instructor on the web.
Mike, come join me on my website. I have over 500 more videos like this that are not available anywhere else. Hope to see you there! It's only $11 a month to join

Scanner I’m 36 years in this trade and love your stuff I’m now directing my apprentices to your channel so they learn more as your a great teacher would love to to catch up if your ever in australia 👍🇦🇺
Thank you so much!
One of the best 17-minutes of learning! God bless you
I used to do this in electronics class all the time in high school; but not with cars. I just walked away with a couple of new things learned- so that's awesome.
SD you do a great service helping others. I think you have definitely nailed down your calling. Taking your passion and using it as a tool to help others. It took you no telling how many decades to learn and understand the knowledge you have and probably the hardest part was finding a way to relate all of your knowledge to thousands if not millions of people.
Thank you for this comment. In the feels man
You tackle the more complex issues ; I so appreciate your lessons ! Super helpful !
Excellent class Danner.. especially the 5v ref sharing bit.. did watch it twice but eventually got my head around it 👍
Glad you enjoyed it
I've been doing electronics for 38 years TV repair I love your videos you're fantastic smart very persistent thank you so much picture perfect TV Las Vegas Nevada owner Kirk Holmes
Thank you Kirk
I thank you for all you do my friend. You are helping me bring my team and our shop into the future of diagnosing complex vehicles.
woooweee been almost 40 years since my Electronics classes in collage. I actually remembered some of this lol Yet you still taught me a lot in this short video. IU think I need to save up and take your online classes.
Thank you! It's super affordable at just $11 a month. Hope to see you there
Same here, used to have those circuit diagrams for breakfast everyday lol. but all made sense, great teacher.
@@ScannerDanner It is like 1 or 2 visits to Starbucks or a skipped lunch one day a month. Bargain of the century imo.
I definitely appreciate your class videos, so helpful thank you
I'm glad you like them! Are you subscribed to SD Premium on my website? If you're not and you're interested, here is the link to join. I offer a 14-day free trial, and it's only $11 a month after, giving you access to over 500 hours of material. www.scannerdanner.com/join-scannerdanner-premium.html
Thank you so much either way!
I feel like that was just a warm-up. I could listened for another hour without having to get up to pee.
Outstanding tutorial , ! Thank you so much ,watching from Vancouver,Canada
Awesome job explaining the whole diagram 👍
Thank you!
Love all your input..Teaching from miles away..Thank You Sir
Thank you!
Thats a pretty smart fuel pump circuit
It was for its time. The weird part is toyota carried that circuit opening relay design way past the VAF sensor life. Instead of the switch in the VAF, the ECM controlled that leg. No prime on those systems either from memory.
Mind blowing tutorial start to finish loved it. No more said
Good Evening Sir ScannerDanner
My teacher
ACCOMPLISHED Sir ScannerDanner

Thanks!
Thank you so much, you didn't need to do that but it is very much appreciated. Happy Thanksgiving!
Thanks. 👌
Good Review on a old Toyota Fuel system
Exactly I had a 1986 1 ton Toyota dually and I own a 1986 Toyota rv and a 1987 Toyota 1 ton dually all with the 4 cyl 22re engine and also own a 1990 Toyota pickup extended cab with the v6 engine but all of them use this sistem (air flow sensor, opening relay and fuel pump ) this video is what I was looking for.
@@Gabriel.A1 nice toyota's 22re is a very reliable engine IN have 5 3rd gen 4runners 97 limited 99 limited a 00 sr5 and a 00 limited and a 02 limited I put a 00 tundra I force v8 in my 00 limited and a 05 4runnr 4.7l v8 in my 99 limited love them old Toyota dually trucks they are good rigs
one of the hardest things for a beginner is knowing where to break a diagram into smaller chunks to keep from getting confused. old cars no problems. these new things are a mess. i wish the manufacturers would break it down by module but few do
Agree !
First, you take in the information; then, you learn the professors "methodology", then things get loud because the class is able to anticipate the answer.
🙏 thanks
Tbh the class seemed a bit quiet during this lesson. I have a feeling a lot of this will come back to them later on. When they actually start working hands on the stuff and they have an "Ohhh, now I see what he meant" moment 😁
This is typical for sure!
It took me a while but at the last 1/3 of the video it all clicked for me. It's been a long time since engineering school lol.
Hello, all I have is the multimeter and powerprobe3. Will your book be worth it for me if I don’t have the diagnostic scanners. I’m a basic DIYer wanting to diagnose my own vehicles. I love the videos. Thanks

Nice! Do you happen to know why in a Toyota VAF the resistor changes in a wave pattern in relation of the vane position?
You're talking about the door position? It's a potentiometer just like a throttle position sensor
A Toyota service manual I own says about testing the VAF:"HINT: Resistance between terminals E2 and Vs will change in a wave pattern as the measuring plate slowly opens." An measurements confirms it.
@firewalker resistance testing a potentiometer will show changes as you move the door. Not sure what you're asking me? Sorry

Hello. I have a BMW 520d F10 2010. It still works normally, only when I press the start button, it does nothing, a advice if possible. Thank you
get a wiring diagram and figure it out. no silver bullets could be anything
What is mechanic service information you used?
Mitchell1 or Shopkey (same program)
👏👏👍👍👍👍👍
Sir, just a question. Can we buy a wiring diagram from you?
eautorepair.adtrk.biz/?a=10817&c=24&p=r&s1=
This is the DIY version of the diagrams and service info I use. I think they give me like 6 cents if someone uses the link lol, but thanks!
👍🏻👍🏻👍🏻🌷
Hello danner, i’m bon from Philippines. I have a question. Have you tried repairing an ecu?
A few times yes, but it is not something I really get into.
@@ScannerDanner what is your comment about ecu remapping or
tuning?
@@bonbon3837
Hi everyone! Anybody may be used scan tool Snap On Ethos Tech eesc321? Is it actual in 2022? For what purposes this scan tool ..... can it relearn throttle?
I think the Ethos series offers bidirectional controls now. But when they first came out, I'm not sure they did
Can you do a video on where to find Accurate diagrams for the Coach-built junk I work on for a living 😂.
If all I had to do was read them it would be absolute bliss.
When they are consistently wrong or just don’t exist, it forces you to attack problems in non traditional ways. Super frustrating.
I can relate to that having owed a 2001 American Coach class A! Absolutely a nightmare!
But all the more reason to learn your fundamentals right? It will help you tremendously
New guy here i was just curious on how to acquire any vehicle circuits online.
Anyone who is aware please help
The professional programs we use run about $160 a month for the subscription. There is a DIY version that you can pay $20 per car

We will. It's just me and the wife my friend. Thank you!
@@ScannerDanner Thank you for all you do. I have learned a lot from watching your videos. Hopefully I'll learn even more from the book.
Thanks!
Thank you so much! You didn't need to do that but I really appreciate the support
