Peugeot 208 P0420 / Catalytic converter diagnose and Fix!

How to diagnose and Fix a P0420 on a 2014 Peugeot 208.

[@benjaminrich9396]

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 :)

[@Diagnosedan]

Benjamin Rich, Lol🤣🤣 That's a great compliment! And learning Dutch is a bonus!

[@2jzazteca]

my too men this guy is easy to understand I would like have it like a teacher

[@turtlezed]

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 KZbin 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'.... ;¬)

'Rev Up Your Engine'...

[@aminmombini6882]

Yes ,you said what was in my mind scanner danner ,pine hollow ,snd diagnose dan,i just don't know how see all of their video😬

[@prakashchander6914]

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

[@Diagnosedan]

Great comment thanks for that!

[@halleffect1]

very true, Dan is a great teacher. Good thing about the internet if used properly we can find these talented people willing to share.

[@andyamanda5777]

The guy is a genius, so very well explained. Better than any teacher I've had at technical school !

[@Qwerty1235945]

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!

[@Diagnosedan]

Qwerty1235945, that's a great compliment!😉

[@arahtson1]

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.

[@Diagnosedan]

That's great. Thanks! 👍

[@CrazyHHO19]

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

[@Diagnosedan]

It happens alot!

[@josephbyrd7769]

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!

[@cru551010]

You are helping thousands of people around the world ... With your knowledge and your teachings !!! thank you very much 👍👍👍

[@Diagnosedan]

😊👍

[@PaulC1980]

Best teacher in this field I've ever watched, anyone training under You is damn lucky, great vid Dan 👍👍👍

[@Diagnosedan]

Thanks👍😊

[@bobt2082]

the way you go through these problems and break down the explanation is quite good. learning something with each video! cheers...

[@Diagnosedan]

Bob T, Thanks!👍

[@MS-ir7qb]

In 20 minutes I learned more from you than a course that lasted several months. Thank you very much.

[@frankoattes]

Another easy to understand diagnostic lesson from Dan the man! Thanks Dan

[@jeremymatthews5169]

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!

[@epiespinoza4941]

Thanks for all the time spending with us Dan!!!

[@Diagnosedan]

I love spending time with you guys!

[@pontiacsrule8761]

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.

[@samuelavelar2700]

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.

[@Diagnosedan]

Thank you Samuel!👍

[@Conservator.]

Samuel Avelar Hi, Your customers must have a lot of confidence in you if they bring in their gas cars to a Diesel specialist. (Compliment, no sarcasm)

[@joncoggins8729]

Been in the trade 35 years but Dan's videos all ways teach me new information. Many thanks Dan 👍

[@corbette111]

Dan, I do have to say you are the best, your comments are straight and forward and you explain things so there is no confusion, thanks!

[@traianburz7563]

This has to be the most comprehensive and easy to understand video for troubleshooting cats :) Keep up the good work Dan !!

[@oda0111]

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!

[@Diagnosedan]

Alin Marinescu Thanx! More Video's comming up😉

[@tespanton3886]

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

[@Diagnosedan]

Ha ha👍 Thank you!

[@TheProtagonist_777]

We need more guys like Dan in our schools. I could listen to his videos all day.

[@blueyfi]

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

[@OneAuto]

I've never seen this yet so it's one to watch out for. I think I've binge watched most of your videos now. Great job Dan 👍

[@Diagnosedan]

One Auto, i have had many more since this video. So you will run in to one sooner or later!

[@stevenmarsh7138]

Just had this exact issue come into the garage today, Great explanation and showing of the fault Dan. Thank you

[@billrimmer5596]

One Auto, we miss u Rob. Hope u r ok!!

[@videosenutube]

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.

[@dyankopetkov9056]

This channel brings a lot of value to the viewers. Great, great job!

[@tankabbot22]

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!

[@Diagnosedan]

Thanks!

[@charlesndirangu9170]

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.

[@murigerick]

Thanks Dan for your detailed explanations on cats! I just learned a lot. Good job 👏

[@Calico_on_oaw]

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.

[@kuengyal23]

Dans just another piece of legend in this automotive industry. Such a blessing to watch your videos and aspiring to become like you sir. Thank you ❤

[@jacktingzon1012]

Im now addicted to your videos dan. Thanks for sharing your gift.

[@Diagnosedan]

Jack Tingzon Ha Ha that's great!👍

[@rickydude2001]

Thanks for the video, with detailed explanation on the diagnostic you're doing,a lot of us are learning a lot form you..keep up the good work

[@Diagnosedan]

rickydude2001, Thank You!👍

[@Yes_Piano]

I saw a lot of tutorials but you are the best in this area, so I signed up....Thanks

[@lawlessize]

Really easy to understand description of the Catalytic converter system. Thanks Dan

[@JoeNunes345]

Great, easy to understand explanation Dan. Thank you very much for posting.

[@Diagnosedan]

And Thank you for watching Sir!

[@vladmoldovanu3504]

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!!!

[@cosimorochira9948]

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. 👍👍👍

[@seftonplayer32]

Bloody brilliant mate. Absolutely amazing work. I'm learning from you, Scanner Danner and Eric O.

[@justinward5865]

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 🌟👍🚘

[@jakobcoff]

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.

[@richardmounfield7822]

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.

[@Diagnosedan]

Richard Mounfield Thanks buddy that is so Nice to hear!👍

[@broncobart4354]

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.

[@alvasingh8054]

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.

[@TheKeenMechanic]

You are some mechanic ah? Every time I watch one of your videos you blow my mind. I wish there were more people like you.

[@lkazanov]

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.

[@mr.technician4144]

This man also is a great teacher....very clear his teaching practical....thesame as scanner danner.....thank you sir for your sharing your knowledge.....

[@laurentnahra708]

I wish all mechanics did their homework like you do....you are great! Thank you for the info

[@Diagnosedan]

Thank you😊

[@michaelangeloferrari4024]

Your videos turn mediocre techs into great techs

[@Diagnosedan]

That would be great!

[@sthedavid4809]

Dan is exactly what we call, the best in the industry well done we appreciate your effort in SA thanks.

[@Diagnosedan]

Baie Dankie😉

[@khalidalmahmode3889]

I really am grateful for subscribing to your channel. keep up the good job, Dan.

[@Diagnosedan]

Thank you!

[@autotek3110]

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 😄😎

[@garethprice4262]

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 👍

[@ahsamahi4385]

You always creative with your videos I always learn something new from you, well done 👍 Dan

[@pshtiwanabdula4776]

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

[@TheHairybabooon888]

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.

[@Diagnosedan]

Thanks for the feedback!😉

[@Vespastendert]

Ive done tons of them aswell. Bad design

[@MrTopgearnerd]

@@Vespastendert There has been a TSB on it with updated part and many have been replaced for free under warranty/goodwill .

[@Vespastendert]

Mikael i know. I left Wassink autogroep in october ;)

[@felixcat4346]

I would think this would be a warranty item.

[@billrimmer5596]

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!!

[@arthurfricchione8119]

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. ❤️

[@Diagnosedan]

I'm full of great idea's 🤣🤣🤣

[@emmanuelkuegbala7630]

your teachings are very amazing

[@user-bl9th4ir9q]

You understand your field professionally

[@kennysivixay9989]

I always enjoy to learn something from you thanks

[@alexandervietoshkin7948]

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...

[@Diagnosedan]

I'm sure it will!

[@roxanneabbott8424]

Always enjoy your videos!

[@kevinarmstrongyoutube]

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!

[@thisisyourcaptainspeaking2259]

Excellent diagnosis, even better explanation! Great job! :)

[@smithstjohn929]

u the best i've being on so many training for me i learn more from u you make things look so simple excellent job bro thanks

[@Diagnosedan]

Thanks for the comment buddy it's appreciated

[@johnjohannemann1220]

Excellent description of system operation and diagnosis.

[@michaelrichter8766]

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!

[@forestchannel6559]

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.

[@deanbusby5972]

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 👍

[@fieldsofomagh]

Great educational video and sound diagnostic strategy . Looking forward to more videos.

[@martinlavoie4002]

Awesome video once again love watching you’re stuff really informative like always

[@Diagnosedan]

Thanks Martin

[@crumplezone1]

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 !!

[@Diagnosedan]

Wow thanks for that!👍👍

[@saiedabushadi4012]

Great explanation you are always clear to the point

[@badboytommy187]

That is the best diagnostic . I was me I would change the downstream O2 sensor 😂 not fix . Dan you are the best auto mechanic !

[@peintiumsix8259]

Good Thanks It helped me. You are really a great teacher.

[@oevieo4589]

I Just watch some of your videos today I am very impressed, you are a master technician.

[@Diagnosedan]

Paul Enimil, Thanks for watching 👌

[@cfauvel]

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.

[@careyautorepairs]

Love this video. Going to look for this crack when needed Dan. Thank you buddy.

[@mobileautorepairbypacheco1806]

You explain everything like a profesional!!!

[@billrimmer5596]

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.

[@Diagnosedan]

I always love your comments Bill!👍👍

[@benking9503]

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

[@Diagnosedan]

Thanks Ben!👍

[@angelramirez7747]
