Catalyst system efficiency below threshold Bank 1
friend u talk too much 😱
CarShed68 hahaha if that's the only bad thing you can say I've got off lightly I think thanks for watching mate
I like that he talks "too much," the more he talks, the more information you can gather about the job he's doing and what to look out for if you're doing the same job in hand.
8ile but he can say same amount in less words and time 😀😀😀
Did it take you 1 day to finished high school?
bodgit and leggit garage, has taken his time out, experiences and shared with us.
And you had to be rude.

Thank you! I just watched this and was able to scan and verify a catalytic converter problem. I really appreciate the detail you went into.
Nice diagnosis, explanation of operation, and repair. Thanks!
Baxrok2 thanks for watching mate much appreciated
Very nice explanation. I did learn a lot on this one. Thanks mate!
Here in Costa Rica we get our cars tested for emissions every year and they're a pain in the *** to pass. Specially for old vehicles like mine. And they test it both at idle as in high rev 2500rpm. Surprisingly enough my 98 S10 truck still has the original Cat and it still works. after 400k km
chungaleta1234 wow never heard one lasting that long that's amazing you must look after it well thanks a lot for watching
I'm a compulsive parts changer, Oil change every 2500 km. High octane petrol and never revving past 3000rmp have paid off.
chungaleta1234 it pays off big time I tell people to change the oil regularly at least once every 5000 miles if you do that you will certainly prolong the life of your engine most people don't listen lol
Hi
Very good video... good and simple explanation for the O2 sensors!
For this one you should have added..."get your hands burned..."
lmsvvavr hahaha yes I should have definitely had it that in as I did burn myself more than once thanks a lot for watching mate
Well if the engine is missing, you need to find it and put it back in, right?
Very helpful thanks will check my parents car tomorrow.... Have you ever had a 04 corolla 1.6 low idle around 653 rpm checked and cleaned maf sensor no fault codes relating to it either
check your throttle body mate
Good info right here. Got the P0420 code on one of my Toyotas. Originally had a too rich code too - replaced the MAF and it went away. Weirdly briefly got a too lean code after that, cleared that and it hasn't come back. Now just the P0420 so it's almost certainly the cat at fault. I did put some Cataclean through it a few weeks ago which obviously didn't work. Tempted to throw some lacquer thinner in in the amounts other RUclipsrs have tried with success, as it's a super high mileage car which I'll use for parts if it fails its MOT royally. I assume it's gonna fail miserably on emissions with that 420 code.
None of these tools (or know-how) available to me unfortunately but this vid along with some others have taught me loads about cat converters. Thanks!
The Internet the lacquer thinner didn’t clear my cat codes
I'm glad the video taught you something mate but I do not recommend putting thinners through your car the damage it can cause is huge especially on Modern vehicles
Similar situation here. Original CEL didn’t refer to the cat system efficiency below threshold, only indicated that I would need bank 1 sensor 1 02 sensor to be replaced. One day later CEL came back on P0420. Would a bad sensor have hidden this cat code or is this likely a MAF problem? I bought some MAF cleaner hoping that might save me a converter purchase 😞
Nice explanation on how the system works and good fix! Take care Leon
thanks for watching mate
Very informative. Thanks for taking the time to educate us.
I need help. I got a scanner says p0420 bank 1. Same as urs and trying to figure out to see if its just a sensor is bad or the cat. Bank 1 sensor 1 reads 3.2 V. Then bank 1 sensor 2 reads .640 V. But should the scanner say bank 1 sensor 2. Or is it just the cat
very good video, Would this improve the power of the engine after the cat replacement.
Very nice explanation Leon of the O2 operation along with the cat. I can see that getting that cat in and out would be a pain in the ass. Good to see that it all worked out in the end! 😊👍
stuzman thanks mate much appreciated thanks for taking the time to watch
Move over Scanner Danner Leon is the new case study king.
Nice video, may have been an idea to explain the wide band sensor 0-5v as well.
richard pearce hi mate thanks for watching I will be doing lots more videos on all the different types of O2 sensors in future videos don't want to put too much in one video
Thanks Leon, excellent stuff as always.
I have a peugeot 207 showing the 1st 02 sensor alternating as it should and the second is almost a mirror in terms of frequency but half the amplitude does that confirm the cat as faulty still?
Regards Jay
it might mean your cat is on it's way out you will have to test it properly also you can test each of your O2 sensors by making the car go rich and lean and seeing if they will respond quick enough
Cheers mate🙂
Being a Mechanic myself I love watching your technical videos Leon, you explain things very well.
How's Shaun's heart rate lately?! Apparently there's a lot of that horn prank shit going around, my Bellend of a boss got me with it yesterday! Revenge will be mine.
cozziekid hahahah you always have to check the horn it's an important part of the cars safety features has to be checked all the time especially when someone is under the bonnet hahaha
Wouldn't catch me doing anything like that 😉
One Auto, lol
Well explained 👍
Love all your different tools, they sure make life easier!
I just came across your channel and thanks for you in-depth explanation. I wasn't sure what the downstream O2 sensor should look like and you gave me the answer I was looking for. Can the same be said if instead of having a regular O2 sensor upstream you have an A/F sensor? I believe it should, but having an expert validate my thought would help me, lol.
Steven Coffey hi mate there is slightly different ways of testing them which I am going to be doing a video shortly
Nice, thanks for the response and I look forward to the video!
thank you... nice easy to understand explanations... great work
thanks mate
A good Italian Tune-up can bring a cat back to life sometimes. Every other month, I take my mother's Passat out on the highway and run it nice & hot for 30mins. Eventually it will need a cat, but for now, this keeps it off for a couple months at a time.
Thomas EXOVCDS yeah we did try a few things on this first but just too far gone replaced an engine in this car in another video with a dead cylinder that didn't help the cat with all the fuel going through it
A bit late, but the flipside of that is that if you're giving it an italian tune up a bit late in it's life, collapse of the cat is a definitely possibility - and that's a bad thing.
When you're going uphill, and start unexpectedly decelerating from 70mph in traffic.
New cat in and it felt like it a set of lumpy cams in it, much better top end performance.
(Source: Ford Puma and a stupid, cheap owner - although the cat was only £100 so not too bad, really)
Have you tried o2 sensor extender? My 2008 Camry runs great. Last year I watched this video and got the cat replaced. About three months later the P0420 code came back. Want to try a cheaper option this year. Thank you.
This is just the stuff i was looking for.Geat vid. Thank's for your explanation.
Alx li thanks mate much appreciated thanks a lot for watching
Hey Mate can I see you change a California approved, bank 1 and 2 removal and replacement including manifold,Cats, and all pipes and connectors.
?
@@bodgitandleggitgarage I think he wants to watch you replace the entire exhaust and O2 sensors starting with the exhaust manifold.
Hi! Have you replaced same O2 original sensors?
I have never had that issue of a bolt breaking or stuck o2 sensor....all you have to do is spray it with penetrating fluid and leave it for 20 minutes boom they come out easy.
lol ok
very very eductional video my son...us mechanics need to be refreshed in stuff like this..especially self employed ones..crackin video
Conor Cousins thanks mate that truly means a lot I appreciate you taking the time to what
I had the same problem replaced my whole exhaust code came back drove 200 miles highway and it went off and has been off for 4 days it’s a ecm update for you computer 2004 Honda accord ex
nice work. A flat line in my line of work isn't normally a good thing 😂
Badgertronix hahah I can see that why that would be a bad thing I suppose it depends if you want to finish work early lol
Hahaha. May be you work in health either as a Foctor, Nurse, Anesthesiologist.
Hi. Im getting the P0420 code on my 2013 infiniti jx35 and when I hook up the scan tool it shows both upstream sensors around 2v and when applying accelerator they go over 3v. What does that mean?
Excellent vid. Maybe a silly question but can a cat. be flushed to improve its performance?
Good explanation on this video! Thank you!
Here in California we have strict emissions laws. A test has to be done on the car every 2 years. It sounds like the emissions laws are strict where you live.
1970chevelle396 hi mate yes yes the rules here for catalyst emissions is strict when the car is 10 years old have to test it once a year when it is newer it gets tested once every two years but we don't have a plug and play in here what they do in the test centre is put an external pipe up the exhaust and read the emissions coming out of the tailpipe I know people have suggested you can trick the computer by putting resistors in the O2 sensors which will turn off the lights but it still will not a pass a missions here as they read them coming straight out of the exhaust pipe
bodgit and leggit garage Here on a new car it doesn't have to be done until its 6 years old. After that its every 2 years. 1976 and newer cars have to be tested. They put the car on a dyno to put a load on the engine while its being tested. 2000 and newer cars they just check to see if there are any codes and that is it. I have the license to test cars, but I don't work for some place that does it. Its not worth it because the government is investigating you all the time. If you make one very small mistake, you have to pay a fine and go to a citation school. Thats why I've never actually tested cars before. California has the worst emissions laws in this country.
1970chevelle396 wow it's interesting how other countries work but I know what you mean sometimes it's just not worth doing certain jobs because it can be more hassle than it's worth nice to know how it works in other countries
1970chevelle396 hi mate I've just sent you a private message would like to hear your feedback on it when you get chance have a look thank you
bodgit and leggit garage I will look at it tonight when I get home.
Love your channel and videos, keep making them!
Thanks mate
Front o2 is .645 (+/- .050) almost constantly. Rear o2 has a wave pattern .1 to .9 . Brand new (4th time) "over powered" converters. Does that mean the engine isn't running properly or theres an exhaust leak? No other codes.
OMG. MAN you're awesome. I finally got it fixed.
ant time mate glad it help you
I got the check engine light with Po420 code but every time I drive 45min-1 hour on the highway the check engine light goes away for a day or two then come back on?
After the cleaner is through and light is still on disconnect battery terminals and reconnect
Fanatic explanation Leon thanks for making the video. Would you recommend a Cat cleaner to try and clean your catalyst converter or are they a complete a waste of time to use there are Quite a lot of videos out there saying to use Lacquer Thinner thanks
Been a tech for 5 years. Your videos are fxcking brilliant. Been a subscriber for only a few months but it's great because u work on UK cars. Eric o is also a legend but he only works on gm's and stuff we don't have in UK.
Thomas exo is cool I watch a lot of his vw videos.
Keep it up!
Jacob Watts wow thanks mate much appreciated thanks for watching
Question, wouldn't a crack or leak in the system affect the readings? Or a bad sensor to begin with?
It will certainly affect your fuel trim and will contribute to cat failure
You are very good at explaining things.One might learn a thing or two :-)
Krillekris thanks a lot mate glad you enjoyed it
Such an amazing world RUclips is. Here on the recommendation of Mr Eric O. And we're on the same side of the pond to!! Great job👍🏻
Kenny B thanks mate thanks for watching and thanks to Eric for the shout out
Kenny B hahaha thanks mate and thanks for taking the time to watch it's much appreciated
Great vid Leon.Some of those Maniverters are a right pain to get in and out think the old Corsa C 1.2 are the easiest i have done.
Cheers
Jamie
Vdubs 60 thanks mate I've certainly done easier ones in the past just part and parcel of this job don't you just love it lol
I heard in some states of America you don't even have to have a cat converter as they don't do emission testing. Damn European laws lol
Good mechanical video and instruction sir
Brendan Brady fan yes I've heard that too about some places in America but over here when a car is 1993 and newer you have to have one in
You are required to have one and it is against the law to remove it. If there isn't any emissions testing you have a reduced chance of getting caught.
Only in SOME states. Most have inspections and tests
I live in the U.S in Georgia, it's actually more specific than sates, its by county for me. I got lucky and I don't have emissions.
@@bodgitandleggitgarage In united states 1975 and newer ALL have cats in ALL states
good explanation and good job but why you don't just clean the catalic converter
عبدالله العريبي in the video I explain this has already been done the cat was trying to be cleaned and was not successful I explained that all in the video
great video leon!!! Do you recommend using catalytic cleaner as a preventative maintenance? They say to use it it 3-4 times a year. My cars dont have a problem but would hate to run into something like this down the line, any thoughts?
Arts&Trusts hi mate it all depends on the type of driving you do if you do long journeys and drive it often it will look after itself short journeys not letting it heat up properly kind of does the damage there is stuff out there you can put into help but I don't know if it really works scientifically but a good hard drive every now and then does more than anything
you got away with it again leon no broken manifold studs . nice vid as always
Pete Rimmington three manifold stud broke unfortunately just one of them things with this type of job thanks for watching mate
(I wonder if you could just put a resistor in series to bypass the 2nd O2 sensor to get the light to go off)
opl500 that might work to take the engine light off but you were still have a problem with the emissions on the NCT test over here they do not just plug it into the computer they put a pipe in the exhaust and check the emissions coming out so would not work for the test
Bastards. Actually doing work to make sure you do yours :P
opl500 hahaha
What Cat cleaner would you suggest? I have an 02 Camry LE and it runs fantastic, no loss of power or anything but a few weeks ago my check engine light came on and I was finally able to get it checked and it came back PO420, of course the technician at Autozone instantly said I need a new Catalytic converter and she had one in stock for $550... Obviously I didn’t jump at that idea and instead started doing a little research, and I keep seeing a “front” catalytic converter that bolts onto the manifold and a “rear” catalytic converter. Idk how to know which one I’d need....but I’d obviously prefer to start with trying the cat cleaner you mentioned at the beginning of your video before anything. Sorry for the long response and hopefully you can be of some assistance, thanks buddy!
Hi I have a ford focus 2015 been getting the p0420 for aver a month now tryed the cataclean but no did not make any difference bought a new o2 sensor and still no engine management light still on I dont have any loss of power a friend says it might be the map sensor?? Not sure where to go from here could it just be the cat that needs replacing ?
Very informative and a lesson in diagnostics . Nice one.
125 SM thanks mate thanks a lot for watching much appreciated
Hi! again very explicit video. I have a question: i do not see any O2 sensor on my toyota . It is possible that? I checked it once with a toyota dealer. We were surprised then. It a D4D 2001 avensis verso ( CD-FTV engine)
great video! Which cat did you replace, upstream or the downstream cat?
hi mate I think you are thinking of the O2 sensors there is only one cat in this car it's just a 4-cylinder upstream and downstream or the O2 sensors
What did you recommend as a flushing additive in the beginning
Hi, my check engine light on today . It say catalytic converter defect . But I have change it one month ago . Anyway I erase the code and check engine light gone . So my question is will it come back again. If so how long it will take to come back. Thanks
Golf 5 ( 2008 )
1.4 patrol engine
I drove with bad kat about a week but no engine light on and after I drove another week without Kat no engine light on . When I change my both Kat and drove 500km not engine light. Then I put fuel injector cleaner and drove another 150 km . And after engine light on and it says on my obd2 Kat defects
Thanks for sharing this informative video. What is the difference between codes p2463 and p0420 .Toyota catalytic converter
Hi mate, 1 is a DPF filter. Code and the other one is a catalytic converter code.
@@bodgitandleggitgarage thank for reply l mean is there a relation between these codes if they are present in scan tool at the same time. Thanks my bro
Class video leon great channel👍👍👍
Downstream O2 output on the new cat looks a little iffy to me . . Cheap non type approved cats tend to have limmited lives.
I agree with you about the second bit yes they definitely don't last as long as a genuine cat as regards the first bit it's all fine the car has just passed the NCT last week so nothing wrong with the cat the emissions O2 or anything
GOOD teacher.
thanks mate
Great video Leon very imformative and educational keep up the great work
Paul Mayou thanks mate
I have both 420 and 430 can clean don't work so I've place 02 sensor extension code gone but I'll be replacing my cat soon
hi mate what you will have to do is you have to diagnose it properly just because you've got the code doesn't mean they need replacing it all depends on what tools you have to what exactly are you can do
Video very very helpful and informative
Spot on mate👍🏼👍🏼👍🏼👍🏼👍🏼
thank you
I have 96 toyota camry LE with the p0420 code . It would shut off while driving and sometimes take awhile to turn back on. I now can't get it to run more than 5 minutes. Not sure if it is the cat or just bad O2 sensors
Hi mate you'll have to do some testing if you've got a oscilloscope or goods can't all have a look at your O2 sensors make them go rich and lean and see if they respond also you can do a back pressure test to make sure your cat isn't blocked he's with the first things I would do in this situation
Very well done Leon.
wysetech2000 thanks mate
What happens if you straight pipe it.will the light stay on. Engine light
Yes mate You will have to reprogram the ECU Or trick it in different ways depending on your car to get the light off
How can you distinguish between a bad downstream O2 sensor and a bad Cat? Thanks for the vid.
Is the O2 sensor is switching up and down and basically copying the first O2 sensor you can be pretty much certain the cat isn't working providing and the car is in closed loop you can check the heater circuit on the O2 sensor you can also force the car to go rich and lean and see what happens with the senses
Well done Leon. Cheers .
STEVE ROB thank you sweetheart
keep em coming
Conor Cousins will do thanks mate
2 thumbs up to you bro!!! kudos!!
Thanks mate
What is the real whole name for that 02 is it front downstream??
Can a exhaust leak cause a p0420?
if have a b1 s1 but not check engine light on but i have this code p031 can can clean the catalytic?
Thank you Brother
Any time mate
My toyota matrix data is just like the first example so I have to replace to exhaust manifold?
Not necessarily you have to to make sure you test everything properly make your system go lean and then Rich and see if everything is reacting properly make sure you have no misfires make sure you have no air leaks don't just go off a video make sure you test everything properly
fantastic video
Scott Tanner thanks mate
p0420 and check engine light. car doesnt have all its power. i have changed the spark plugs, what should i do next?
don't just change parts like I explained in the video you have to diagnose it properly if you don't have the right tools and diagnostic equipment you're going to have to go to somebody who does changing parts is absolutely pointless and a waste of money
Thank you
You're welcome
Can't speak for the mainland but in N.ireland they don't test the cat for MOT.
Kenny B lucky lol
Take cat off, and shove a pole and hammer up it repeatedly until cat is empty, or cut open the bit that goes against the body, empty it out and then get it welded back up. Will have an EML light on, but no problems. If you have a newer car you can get the O2 sensor mapped out.
8ile then it would fail the NCT and you will have to do all the work all over again to put a new cat in
Most petrol cars can pass without the cat's with no problems? Loads of boyracers have de-catted cars, even diesel's.
8ile a petrol car that's 1993 and newer in Ireland will not pass without a catalytic converter in
But you changes the catalyst and the sensor. Win win
Why not change the sensor first?
What if it cranks but dont wanna start
good ,thank
Hey there, I was wondering if you could help me with my 2010 Aveo5. I only have a P0420 code, but its a hard start (like engine misfire) and kinda noisy when accelerating. Could it be a Spark plug/misfire problem or do I have put out more money for a new Cat than what I paid for the Aveo?
Hi mate yes it sounds like you've got a misfire issue easiest way to check is just start the engine remove one coil pack or HT lead at a time and see if the engine changes note if it doesn't change note you know you have an issue with that cylinder then you can check the spark plug coil pack etc
Very much
did old cat had burned hole? i asume that old cat was ok,just wrong fuel mixture was make this foult,too big LTFT (long term fuel trim) 😃
My o2 reading are good but I keep getting po420 popping up after about 15 miles driving after clearing codes any ideas?
You're going to have to do a lot more checks mate you're going to have to check your fuel trims then check that your O2 sensors are actually working by making the go rich and lean once you're done all these checks your fuel trims and your O2 sensors then it can only be your cat also you can check your fuel pump check your injectors lots of checks unfortunately
Why I’m so easily distracted by the dog next to your head? :)
lol
what year is the car and how many miles or kilometers??
Gold 👍👍
How much is the part I need one.
my friend i have a 2013 mustang v 6 i got the same code for bank1 and bank 2 my car got something when hit full throttle the car rpm go from some 1000 to 2000 rpm so slow the car launch is so bad and when keep doing full throttle its start to do something like misfiring its keep cutting of and keep lagging but i got no misfire code any advice
First thing you need to do is stop driving at you will just cause more damage you could even damage the cats which would be very expensive on that car you need to get it diagnosed properly before any more damage is done could be just a simple case of needing O2 sensors might need more
@@bodgitandleggitgarage thank you man will check it soon
witch one is bank 1 ?
1997 Corolla with same code, you think the cat is bad or just the first O2 (closest to engine) is bad?
Not cheap if it is going to be a cat, don't want to put too much money into a 21 years old car.
angelisone hi mate do you will have to do some testing to find out exactly what is wrong first
bodgit and leggit garage, I thought with many years under your belt, you would know by experiences.
Thank you for replying back.
The Air flow to Cat is CO not CO2, CO is Carbone Monoxide it is bad dangerous air ,CO2 Carbonic is the not bad air it is same air in your soda drink.
Is this the same crolla you fitted an new engine to?
tom clifton yes mate that's why this cat is destroyed as the Old engine was missing and just all the fuel went through the cat and burnt it out
The government should pay for emissions repairs..
There the ones who want this junk on vehicles.
And acually ALL the people needs this junk on vehicles. Yes the goverment should pay for it, but you should be the one who cares for your own junk anyway.
Well if you want us all to die from pollution, let’s have it your way. Shit happens that’s why we both watched this video
