Thanks so much Brandon

What tools ? What you look ? And how you pointed out the binding part of the drive train that was slowing down the crankshaft to cause false misfire?

Abundance of knowledge thank u

My car had mot, passed with no advisories emissions all good. But light came on for engine management and plug in the computer and gave this code. P0420 1+2

Thanks for another great video. I have caught so many bad batteries with the scope. I had a carbon pile load tester and digital resistance tester tell me batteries were fine when the scope showed otherwise. This is even "new" batteries off the shelf that were bad.

great video sir

One of those videos that everyr single DIY person should watch and study - even qualified technicians who maybe forgot what they were taught I have watched your videos quite a few times now and my confidence improves everytime. Thank you for sharing your years of knowledge and experience.

Thanks Brandon. Do you recommend a book for learning to analyze the wave form?

I GOOGLED IT A WHILE BACK, GOOGLE SAIT ITS PRONOUNCED "MALE". BEING A BMW TECH, WE ALSO USE MANN FILTERS.

Old school teachers always the best!. Thank you so much

Does your autell need a current subscription with autell?

where is your shop?

extraordinary video and very interesting as always, thank you for sharing your knowledge

As an aircraft electrician I always do at least 2 tests. Check for voltage AND test pump resistance. Takes seconds and confirms everything...

Ty for a great educational program!!!

Obviously we’re Not the same. Otherwise tell Yourself that

Escellent presentation Brandon,I just learned something new.you see your videos are among the best in you tube.please keep them comming.God bless you.

Great refresher by Brandon Spectacular

Great job

good lesson brian

teach us

The "money grab" codes

Jason said that his technician tested all powers and grounds did everything correctly before condemning faulty module why did he missed the ground G101 please can you explain thanks

Hi Brandon, great video and, once again, saved it to my KZbin diag folder. Two questions come to mind... 1- Do you have a rule of thumb to determine at which point the time difference is to short and you are confident to condemn the CAT? 2- Should I back this up with scope data? I ask because although I can see there is a time difference on scan tool graph data, I don't really see the time base so ti makes it hard to judge. Thanks again for all your do for the industry.

Nice 👍

Your electrical principles explanation has been the best i have found on youtube... And i have watched a number of them

This video is gold

Customer goes to AutoZone because they charge less for the battery and install it for free. Or they just do it themselves

Great video thankyou for posting

thanks mate 🙂

Thanks

Coil drivers have been an issue in Fords coil on plug, cold solder joins

Good video and explanation!

This is what I call KZbin University if you select the right classes, you will graduate with A+. Thank you! Motor Age classes are the best. thumb up! please share like and subscribe.

Very good

That's the problem if u work among theves and sell outs they can't see anything nice they'll take it the system rewards bootlickers and theves

Very good explanation expensive equipment they will steal it if it in Oakland

Helpful information! I have the Autel AL519 which told me I had an issue on Bank 2. I deleted the code after checking the front & rear temperatures, as the drivers side seemed to have a wider difference between the two (which I believe is bank 1) as I have 2 converters on my F150 pickup. Interestingly, it's been a week, and after having the initial code come up, it has stayed off, although I will test again today. Thus makes me wonder if it was a random code that popped up for some reason? Nonetheless, it's something I'll be keeping an eye on. Thanks for the video! Having 137K on the truck, I would imagine the converters 'may' be getting to the end of life, but I'll continue to watch for check engine lights. Fuel mileage hasn't really changed either.

So since N2 Nitrogen molecules are slightly larger than CO2, would one really be better than the other? I have a tank of Nitrogen for welding is why I pose the question.

Tremendous amount of detail in a very easy to follow learning curve ! Thanks again Brandon ! Thanks for “feeding “ our appetite for mastering automotive diagnostics . 👊🏼 🔥 🐱 💻 📈

Yep keeping your skills updated is always a great benefit to yourself and others you choose to help

Thanks for this Åge. Well first I don't understand anything?? Just kidding haha . I got a little lost today too. Now understand why the Fiat 500 is not used to haul large loads of timber. Many thanks to you Åge😁

as usual a lot of good information. I really enjoyed the forst section describing how the cat works. it helps me understand why the post cat o2 sensor does what it does. my question is how do you check a cat with a wide band sensor that hardly moves on the screen. it's one thing I can't wrap my head around.

Honda tech could have also "Ohm" tested the primary winding on the pump before replacing.

Ty sir for taking the time out and giving us a refresher!

Third video about mass air flow sensors that call for replacement. In many cases the sensor is dirty and they make a special mass air flow sensor cleaner.

thanks for this video, and woul like to have access to de spreadsheet

Great explanation. Thank you

Brandon two questions for you at the 13 minuter mark you were discussing how unwanted resistance before the fuel pump will cause a reduced ammount of avaliable voltage to the pump. you say that reduced voltage will cause the fuel pump to be damaged, how? what is happening in the pump that would cause the damage. i was always thought to substitute the load with a comparable test light to stress the circuit. my question is how do you know what size light to install in the circuit. you can measure the resistance of the good or look it up on service data but that is not always a reliable way to come to that answer.

Excellent video Brandon
