With no loss of love to Scannerdanner, Eric O, Ivan, and other auto-electrical content providers - Dan is so my new favourite video provider. Scannerdanner got a lot of us into scopes, Eric O got us saying "there's your problem lady", Ivan got us writing stuff down. By the end of the year we'll all know PIDS and faultcodes in Dutch and be saying "guys" a lot. :) Great stuff :)
You mean 'Guysh'.........to get the accent dead on......He's definitely an impressive technician (and a neat tutor / film producer to boot), they all are but nobody is going to learn to be a complete technician from watching RU-vid vids, you need training and time on the job....who do we know who offers training and has a book?...cough ..cough.....hmmmm ...ahh yeah........ S.D.......no not Scooby Doo......Scooby Danner...might sign up for that ebook Paul there's absolutely shedloads I dont know about modern systems. I enjoy watching them all to be honest with a strong interest in the electrical side... the real mystery is looking for the no start imho of course........'and i would've got away with it if it wasn't for you pesky kids'.... ;¬)
I am learning more here than I have ever learn in my entire career including Tech School. Dr. Dan you are really a great teacher. need more A/c Diag Videos. Thanks
Dan, that's the best explanation as to how cats work I've ever come across. I knew the upstream O2 pulsed, and the downstream should stay static, and I now understand why. Thanks very much. Great diagnosis there! I'm loving watching all of your vidoes!
I just found your channel a few days ago and I am addicted to absorbing all the knowledge you drop on us. You're a god send for those of us that enjoy the diagnostic side of things and want to be able to be 100% confident in our diagnosis. Thank you for what you do!
Another great, well written video. Guy explains everything in detail & too the point. He is very knowledgeable & patient. Thanks for taking busy time out of your day to make these videos. We really appreciate it.
Very good video Dan! It's refreshing seeing professionals who perform actual, good quality diagnostics, not just part swapping. Keep up the good work, looking forward to seeing more videos in the future!
Dan, I have been struggling to understand how the O2 sensor works in conjunction with the catalytic converter and you explained so clearly now I got it, thank you very much from San Francisco California.
Charles Ndirangu, Thanks, Dan for your exceptional training on various Car diagnostics that save us and our clients a lot of money and time. Keep up the good work you are doing.
Awesome video Dan! You are a great teacher! Ben is right, the whole community of techs and diagnosticians, sharing the wealth of knowledge. We appreciate all the hard work!
You are my new "logic" man Dan. I'm slowly makimg my way through all your videos. I take my time and absorb your explainations. Thank you for validating my past diagnostic conclusions contrary to what my supervisor "guessed" should be done. I'm sure you mostly and others have given me the confidence to go it alone on remote calls.
Brilliant information. I've seen 6 catalytic converter p0420 videos so far. This video was very well explained and visually demonstrated better than any other video . This video was easily understood and I appreciate the time and information!
Wow well diagnosed , I particularly like it when the before fault and after fix is shown making it a proper fix video .I have recently subscribed and am enjoying watching your professional approach to diagnosing and fixing the faults. regards Rich.
The best channel for a mechanic technician to learn from somebody who actually understands how automotive systems work.you are a very good teacher.there are many guys who probably have the same abilities as you do, but being able to explain how things work is a talent that is rarely seen.you make everything seem so simple although it is fairly complicated.i wish you success with your business and channel!!!
I’ve been wrenching for almost 20 years and I always learn something from this guy! Love this channel. That being said I would’ve added a smoke test using the downstream O2 sensor bung and a back pressure tester. I think it would’ve been evident through that tin foil looking heat shield as you could see the suit collection from the very beginning.
Sir, you are absolutely superb in the way you present the topic. Very professorial! And I also like the fact how all of this can be extrapolated to many other cars. Very nice, please keep up the good work.
Hi Dan just stumbled across this one, great diagnostics from you and good old fashioned weld repair its so important skills like welding are not lost also you've saved someone hundreds of euros rather than replacing parts at a customers expense, excellent service and a fantastic job 🌟👍🚘
We need more mechanics like you here on youtube.my wife have 208 with same problem. i will investigate and have closer look on any cracks on cat as you mentioned..thank you
I like your honesty and attention to details, you are a genius and a real professional, you're what every auto tech should be before they bear the title of their trade , I research the Internet a lot and realise thousands if not millions of vehicle owners are scammed and conned into throwing parts at their cars which still don't solve the problem, when it was just something that simple , it shows that you love what you do and and when you help people genuinely god will bless you exceedingly abundantly more than you can imagine , stay blessed.
Thank you sr. From Oakland California. I'm a Diesel tech but some of our customers have Gas engines this comes handy. I believe you do your best to feed your viewers with good and reliable info.
Great piece of info. Great idea to weld seeing as they are not cheap. I watch them all and learn something new everytime and the best part is it just don't apply to the car your working on. It can be applied to most. Thanks Danny. ❤️
Only just came across Dan last week, have subscribed and watched quite a few videos already, find Dan to be very knowledgeable and explains things well. Thanks Dan, keep up the great work. From all the way down in Tasmania, Australia, Cheers. Bluey
This man also is a great teacher....very clear his teaching practical....thesame as scanner danner.....thank you sir for your sharing your knowledge.....
I just want to say thank you very much.....I had same issue and I followed your suggestion... I actually found the catalytic converter exactly like yours in the video. Thanks again.... I saved a lot of money. 👍👍👍
I have seen many Mechanics talking on youtube.But lot of them talking the same thing over and over again.I have seen many vedeos of yours you strait in to the fact.That way we don`t waist our time.Keep on doing great work.Highlly recomended.
You are a top man, Thank You, I have a 02 sensor fault with my wife's car dan and I've changed the cat and all the 02 sensors and still the downstream sensor is saying there is a fault! So I'm going to follow your diagnostic procedure, you have been very helpful, I didn't actually understand how the cat works other than filtering out chemicals for the emissions, very very helpful video dan, Thank you so mutch
Great video. Not sure if this was in the many earlier comments. For those in the USA, warranties on the emissions system components is 8 years or 80,000 miles. If it beyond that follow Dan's advice and save money and natural resources. Keep up the great work DAN!
Im currently spending time looking at emmisons data on a BMW Z3 for a very small intemittent running fault.... been using my scopes etc... cars giving no fault codes either...... need to look at it again. But just to say.... you are by far the best tech out there.... as you fully understand what your looking at. Only discovered your vids a few days ago.... im hooked now 😄😎
Best I ever seen on you tube and hope you have a good health and your good work may continue as I learn alot every time I watch one of your videos. Best regards
Those r great learning videos. I am rewatching them. U used to use the Snap On scanner all the time. I am using mine more as I am learning the playback feature and how to record and play back. Thank u Dan!!
I like the way Dan goes into details while explaining, just by one topic you learn so many other stuff. Had to come back just to like this video as my tv does not have the option, the 1000-th like haha
Another case of the same problem to report here. Started getting the error code at 69k miles. Removed the cat and welded it up today. I have seen evidence some main dealers want £1000 to fix. Seems unfair for a design flaw. Thanks so much for your video, gave me the confidence to tackle the problem.
Hi Dan Peugeot mechanic here. Your right this is a common problem. New one when warranty are picking up the bill. Weld when customers picking up the bill. I've actually got photos on my phone from the first one I welded.
Thank you bud very helpful, just found it and you was right no sound of blowing from the exhaust due to silencer sound proofing. Just got yourself a subscriber . Keep up the good work 👍
Hi , First of all, thank you about videos you share and make it for us, I am master technician and diagnosis cars, really i like to watch how you work and very perfect diagnosis , i hope in one day visit you in your workshop, make alot videos and share it. Thank you again
Great video and thanks for the explanation! It's hard to find something as clear and well-understood as the explanation provided. I have similar trouble on a similar car and I'll try to follow instructions, hopefully it will work...
I would love to have seen u weld that little bad boy. Super explanation of what Cat is supposed to do. I going outside right now and checking my downstream sensor voltage on my 2.5 Nissan Frontier. It has a wide band upstream though. No worries. I saw your video on that too.
Congrats man, awesome video, great and very detailed explanation!!! I have a 2015 Peugeot 208, 1.2 engine, showing me the same code. Now that I understand the problem, I’ll try to see if there’s a problem with the sensors or the actual catalytic. Thanks again!
Thank you for a good video. Got the P0420 on the wife's car, and it turned out it had the same crack. It is a Peugeot 2008 1.2 VTI from 2013. I welded it up and hope the P0420 doesn't show up again.
Another great video DanTheMan....Working on my daughter's 2007 Altima, we had to replace the CAT twice. The first time, we bought the car with a loud exhaust leak...I suspected the joint between the exhaust manifold ant the CAT (it is one piece like this video)....sure enough there was a large crack ....but no codes being thrown. Bought a new CAT/exhaust and in a few months the same damn thing happened...this time the new part was covered under warranty. No codes too...just loud exhaust sound. Apparently a very common thing on the Nissan Altima.
Thanks Dan for your video👍 my O2 sensors are switching the same before and after the cat. It looks like I have a bad cat, but I wouldn't of known this without your help. Thanks again 👍
