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 TH-cam 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!
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.
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
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!
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!
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 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!
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.
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!
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.
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.
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.
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.
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 🌟👍🚘
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.
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. ❤️
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.
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
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.
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.
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.
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.
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
This man also is a great teacher....very clear his teaching practical....thesame as scanner danner.....thank you sir for your sharing your knowledge.....
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.
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.
i have had several of them with same problem but on a v6 engine design not cost effective due to labor cost to just repair and maintain a warrantee on the work ..... now on a inline 4 were labor is not so high i can see this as a repair .... great video dan ....
Another great video. One thing I am not clear on is how air can enter the Cat when the engine is running. Even with a crack in the case, the gas inside of the Cat is pressurized higher than atmospheric pressure, so any gas movement would be from inside the Cat towards outside of the Cat.
I use this word very sparingly as I am a hard man to please, but you Dan are `Phenomenal` ! :) Also I have a Yamaha R6 and I had diagnose a no start situation, so checked the obvious No fuel in tank lol, then did the `Easy Spray` trick direct into the intake and it started briefly..so it is fuel starved, then went and checked the fuel pump relay and bingo it was faulty,,changed out and Yammy now firing on all cylinders, so Easy Start for the win !!
Thanks for everything !!! 2006 ? 4.6 Chevy van parked 2years company parking lot. Came for smog check with lean code but pass tail pipe smog good .found few broken exhaust manifold bracket bolts because factory machinist use intermediate tap only when mechanic install they were not tight enough so force more then broke many bolts. So I purchased bottoming tap and cut little more to the bottom and original bolt made no air leak cleared DTC and passed smog check .
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!
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
greetings from london i learned from you what i didn't learn working in my garage for years i know embarrassing you are my new hero and the video with the second bridge and people equals less resistance ... ohh my how do you come up with that !!! DD for prime minister !!!
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 😄😎
If we don't use your idea to add fuel for testing upstream and downstream sensors we can not find the reason of catalytic converter cracks. Thanks for sharing this information to help technicians
Have had this code recently on a Jeep Wrangler, as well as P2096 and P0298 codes intermittently, another shop had already replaced the catalytic convertors and changed the exhaust manifold gasket, the problem ended up being a software level fault and a PCM reflash was needed so off to the dealer it went. I believe the reflash was to stop the PCM being so sensitive to lean conditions on the downstream O2s and throwing false codes.
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
Great stuff, DD - I'm working the same code on our Focus 1.0 Ecoboost ( coming up 100k km) MY 2015. Spraying soapy water around first to see if any leaks visible. 👍🏻
Dan, love your videos and wish I could edit as well as you on mine! One thing I saw on your Peugeot is that you did not mention was that when you forced it rich the REAR O2 switched back low BEFORE the front did! No way that can happen unless there is an air leak between them. Keep up the great information!
Might want to check those engine mounts. Broken mounts will cause the engine to launch breaking all sorts of things. Great videos. Thanks for what you do.
mate you are doing everything so correct, thank you. I solved my problem but keep watching your videos and i,m not even mechanic, just repair my own cars myself :) I send my friend to 3 different mechanics , with are considered the best in city and they cannot fakin diagnose whether the problem is in wires or in throttle body :( waste of time and money.
Funny to see this Video now, Last week we had the same Peugeot model, around the same build year , same fault code and around 70.000 KM on the clock . I called the local dealership, and the Converter was replaced under warranty, at no costs !
I looked it up today , and the total kilometers was 67.563 and a 2014 model as well . I called again to the Dealer to ask what the problem was , but the mechanic was told to check the fault , confirm catalytic converter fault, replace said converter and turn the faulty converter over to Peugeot for warranty . So he mechanic couldn't tell if it had the same crack as in the video, but my guess is it was the same problem. Great videos BTW!
@@lorenzodagamer2485 ‘Of course he did , it's a dealership ! He didn't know if its was an improved version ,or just the same thing, resulting in the same problem 70.000 km on.
Peter Lenderink This a very good example of why I prefer an independent shop. A mechanic at a dealership is trained to and has to follow prescribed procedures to the letter. At an independent shop a mechanic has to be able to analyse, diagnose and then solve problems. (Only) proper diagnosis and root cause analysis will solve problems in a robust and cost effective way. 👍 No disrespect for a dealership mechanic. It’s just a different type of character that’s needed for a dealership or independent workshop mechanic.
Aissaanes Lyes, this is only possible when both sensors are the same. Most cars have got a wideband upstream and a narrowband downstream sensor. And ofcourse you try to diagnose the car as fast as possible. Measuring is faster than chancing them out.😁
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. 👍👍👍
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
I took out my DPF, EGR and CAT. Sold it for 300$. Paid the local guy 80$ to remap the ECU. And had 270$ left for Greece holiday. Yeah. Save the planet.
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.
With no loss of love to Scannerdanner, Eric O, Ivan, and other auto-electrical content providers - Dan is so my new favourite video provider.

So you will run in to one sooner or later!
Just had this exact issue come into the garage today, Great explanation and showing of the fault Dan.
Thank you
One Auto, we miss u Rob. Hope u r ok!!
Tempted to do the same,but I am diagesting one at the time...and then repeat again.Mr Dan makes all so simple and clear.

A mechanic at a dealership is trained to and has to follow prescribed procedures to the letter.
At an independent shop a mechanic has to be able to analyse, diagnose and then solve problems. (Only) proper diagnosis and root cause analysis will solve problems in a robust and cost effective way. 👍
No disrespect for a dealership mechanic. It’s just a different type of character that’s needed for a dealership or independent workshop mechanic.
Good , great sense of this concern of the diagnostic symptoms..........
Switching between the two O2 sensors is an option to know if our downstream sensor is good or not , just an opinion , you are the master
Aissaanes Lyes, I'm not sure what you mean can you explain?
I mean change between them, the upper sensor will be down and verse versa !!!
Aissaanes Lyes, this is only possible when both sensors are the same. Most cars have got a wideband upstream and a narrowband downstream sensor. And ofcourse you try to diagnose the car as fast as possible. Measuring is faster than chancing them out.😁
Hats off to you sir you are genius
A RAHMAN Thank you so much for the words, but i don't think I'm a genius🤣
@@Diagnosedan you are really a genius and very humble, may the Lord be with you and increase your wisdom!
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. 👍👍👍
Great description - especially that you describe what you expect in a well-running engine! Thanks a lot.
Thanks!😀
your teachings are very amazing
Thanks Dan here is a little something for all your hard work. Thanks buddy!
Brilliant video, explained a lot I never really understood.
I always enjoy to learn something from you thanks
Bardzo fajny film o diagnostyce peugeota. Sam mam problem z układam katalitycznym więc lecę rozbierać osłonę katalizatora.
Daj mi znać, co myślisz😁
DiagnoseDan Peugeot 301 z 2014 roku ma ten sam układ katalityczny i ten sam problem, pękający katalizator.
Jacek Adamczyk Świetnie💪
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.

23 catalytic converter manufacturers. Lol 😂
Sir,den I have learned a lot from your explanations.
That's great news!
I took out my DPF, EGR and CAT. Sold it for 300$.
Paid the local guy 80$ to remap the ECU. And had 270$ left for Greece holiday.
Yeah. Save the planet.
Thanks Dan for your detailed explanations on cats! I just learned a lot. Good job 👏
2015 Peugeot 308 1.2 thp thank you so much that error code was driving me crazy welded and never seen the code 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.
Dan you are my best guru ever❤️
Perfect. Been looking at this fault and changed 02 sensor but code come back. This will help a lot.
Finally i've understood. Many many thanks to u dan.
Wow you make everything make sense great diagnosis
Thanks Chad!😉
Very good upload!
I knew it was cracked a soon as the video started, it's a very, very common problem, we weld at least a couple a month......
