Quick Fix for P0420/30 Engine light Codes
Вставка
- Опубліковано 21 сер 2024
- If you have the P0420 or 430 codes and you want to save a little bit of money before having an inspection or replacing your catalytic converter do this and it may or may not work for you for a lot cheaper price than replacing your catalytic converter.
You guys are missing the point. He’s showing you how to pass emissions.
thank you!
Anyone remember cars before they had catalytic converter? They ran strong 400hp with an edelbrock cam, manifold, and a Holley carb . Run some glaspacks or straight pipe and let them good times roll.
Terrible suspensions
I got the code. Car still ran good though. Recently I got the p303 code which is cylinder 3 miss fire. Replaced plugs and ignition coil. My 2016 hyundai elantra with 175000 miles runs like new. Maybe the unburned fuel was triggering the 420
worked for my 3.5 ecoboost without drilling
Unfortunately, some sensors are fat so they don’t fit exactly into the non-Fowler.
Did its turn the light off ?
@@JuanTello-vs4lt yes, it would come on if I got a little heavy on the gas, I tested it for a whole day and it never came back on
@@jblaze114 my truck is a f150 3.5 twin turbo 2015 and i replace the catalytic converter and the sensor for bank 2 and the light is still on and its the same code for bank 2
@@JuanTello-vs4lt did you clear the code? once i cleared it it never came back on
Thanks mentioning to reset. I was wondering why light didn’t go off
Did it work for you?
@@catcola1061 it did. Thank God
Great idea Temporarily but dont ignore forever the real issue
Indeed, eventually, someone’s gonna have to replace their catalytic converter.
Nah, I’ll ignore it forever. But thanks.
The real issue is that most women shave it all the way. When we all know they must leave at least a little hair🤏 c'mon, just a little patch is all I'm asking.
Great Idea. For not fixing the front cat you wind up ruining the rear cat. Now you need two catalytic converters.
If there is no sensor after the rear cat, then you can actually cut that completely out. ;) it’s basically just a helper cat.
Better than a bob cat
@@vehicfixbetter than a bob cat
Alot of cars just have the one
Why do people insist on drilling it from that side?
Drill it from the bottom side and you won’t have to worry about the threads.
I do it from the inside as to keep the small hole at the end in tact if i can. Depends on how big/long the o2 sensor is that i am working it. sometimes they are small to where i can keep the hole and it works better. Sometime even if you drill through you may have to use 2 fouler's to extent it further. know what i mean?
Hmm 🤔 I’m not sure that fixes the problem since it causes turbocharged over boost in lots of vehicles that causes gaskets and valves to fuckup causing more issues.
A cat delete fixed my issue!
Extending an O2 sensor will not cause any type of overboost
Pass emissions if you have that in your state but doesn't really solve the underlying problem
No emissions here in Alaska. ❤❤❤
Same in Michigan
Still cold there. So much for global warming.
It works temporarily, but the code will come back overtime. I hate permanent codes.
It’s a temporary fix for those who need an inspection, but want to save money to repair or replace the cat if not, even get rid of the car by then lol
@@vehicfix True indeed.
so do i put the spacer on the front 02 or the back 02 sensor
always the rear after the cat. front has to see dirty, rear has to see clean.
Last week I added O2 spacer then rest the CEL it went off for while but it came back on again maybe after 200 miles because I added just 1 spacer. The problem is I noticed that car started consumption more gas than before " 2.4 engine " , the downstream sensor still gives to ECU reads about gas mixture. So in my opinion thats not worth. Maybe better to buy aftermarket.
It’s a quick fix just to pass inspection for the time being. Once you do it, you can always put the sensor back and drive normally again.
@@vehicfix just to trick car ECU. Anyways, I removed it before inspection because the car was consuming gas crazily. I reset the check engine and drive it all codes were ready and went to inspection immediately. I passed in safety and emissions. Left the store maybe by 3 miles check engine came back . I said you can hangout there for 2 years i dont care 😮💨
Once you do this.....does the catalyst monitor complete?....cause if it doesn't you will fail smog🤔
This I know, and yes, it does complete
@@vehicfix once it completes...what do the fuel trims look like,.....cause the monitors can be completed, but the fuel ratios can still be off!!
@@crystrezerex2life usually it’s done to complete to pass inspection. If it causes any fuel consumption problems, then you can always put it back to normal and drive around with the check engine light.
Yea then ur driving but until converter gets bad inside u have it change it anyway
I tried this. Still can't the fault to go away
My 07 Honda accord had aftermarket Cat installed and now the OBD II sensor says my sensor “Bank 1” air/fuel ratio is what’s causing check engine light and nothing else was detected what so ever. Is it possible that all I need is a new sensor for bank 1 ? And does is it need to be OEM sensor ? I believe the OEM for my Honda accord is “Denso” and also does the sensor for “Bank 2” also have to be OEM denso brand ? They replaced the “Bank 2” sensor since they stole my entire CAT and almost the entire exhaust system and I’m wondering if the bank 2 sensor is aftermarket and somehow confusing the car and causing the Bank 1 sensor to mess up. I really need help bad with this because I can’t find any used cars at all what so ever In the $8,000 price range that have less than 120,000 miles with good gas mileage and all I can find all over Northern California is the stupid ass “09’ Toyota Yaris” in my price range that’s decent on gas and I do not like anything about that car so I really need help whoever reads this message and what I should do ? Will the aftermarket CAT pass smog if I have OEM sensors in bank 1&2 ? Or is it possible the CAT itself even with brand new OEM sensors still fail smog if I replace the sensors with Denso brand OEM ? Please help haha 😂 I have 178K miles on my Honda and it runs amazing even with the issue I have rn… not a single issue besides this problem. What should I do y’all ? Thank you! I have the PO420 code and says Bank 1 sensor. When they put bank 2 sensor on the new aftermarket cat I wasn’t told if it is aftermarket sensor or OEM either. Do I need to replace both with brand new denso OEM ? And even if I do will it pass smog even with the aftermarket CAT ? I don’t wanna have to buy a new car or a new cat..
A lot of trouble and expense to clean or replace a simple approx 3" diameter metal screen permanently affixed inside a soup can, that if were designed properly could be accessed and removed by anyone with a wrench.
Well, not everyone is a wizard like you, Dave
@@vehicfix
WIZARD???... I'm just questioning the total inconvenience, expense and waste of this device. There are other channels that say the sensor will be tripped when the efficiency of this device drops only 5%... from 100% efficiency to 95%. "If you got 95% on a term paper would you drop out of the course?", as one channel says.
In your own example the screen of the CAT seems to have a couple of white smudges. What is the composition of this material and what is it's state: is it a powder or soot, or is it glass or even ceramic (hard)? No doubt the CAT does not glow red in these areas and that would reduce the overall efficiency somewhat and possibly trip the sensor. Why can't this material be directly analyzed and a solution be found to its chemical formation and elimination rather than the blind trial and error process that goes on now.
And it is a waste because many a good functioning vehicle has gone to the wreckers because the owner did not want to gamble $1,500 to replace an enigma.
Thank you.
What happens if you don’t do anything and just keep driving the car with the light on?
my mileage SUCKS compared to when i first got my cruze, i’ve had permanent p0420 for maybe 2 years now
@@dmitrii_s4125hi i have this code a fuel exceso de what i can do??
How far down in the spark plug now Fowler do you drill?
usually enough for the sensor to fit nice with out touching at the end. some cars might have to go all the way through, and some no. depends on the sensor itself.
I remember these 😂
What happens when you just install it and do not drill it
Sometimes the sensor is to big and long so it won't fit.
Well, just hoping you saved me $500 on this job… we will see…
Did it ??? Sincerely asking
@@juliocruz1695imma try it bro tomorrow the day ill update you
My 2003 trailblazer has the p0420 code, and is running somewhat rough. Will the non- fouler make it run better?
No. If it’s running rough, most likely it’s misfiring which is resulting in damaging your catalytic converter. Do you have a check engine light? If so, get a check and see if I am correct in my statement.
No miss fire code. Tho it feels like a miss. I've 2 codes under p0420 which suggests oxygen sensor, ECT.. what do you think? It runs strong under excelleration.just misses at idle while not moving.
@@richardhodges7228you end up fixing it? And what did u do
@@Mtimes2 no I didn't get it fixed, I noticed in the airbox on the right there is a small tube connected to it and it is dripping out gas into the air box .
I also changed the spark plugs and blew out the air filter and clean the throttle body again which was immaculate already and I still have the same problem, and on my OBD reader I'm yellow, and no codes.!!
Is it the same non fouler size for every o2 sensor?
Yes. The only thing you have to do is drill out of the bottom portion not the threads just the bottom portion to fit the head of the O2 sensor down into it.
@@vehicfixwhat size bit?
@@michaelchavez1308 21/32
tricking it won't fix the problem but I know your intention is to trick the emissions for test.
Temp to save $ for repairs.
Dr Venture!!!! Just clickit
haha Jack of all Trades! ;)
@@vehicfix his fire stick tutorials are invaluable
Did that, fixed the P0430, now i get a random P013B code. How to fix that code?
the sensor itself may be bad. it's giving a slow response.
What if the cat is stolen? But I have the sensor hooked up to the computer
Can you be a little more specific? Sometimes if the sensors on the cat, they’ll just rip or cut the wire.
Tried that didn't work for me
perhaps the cat is so far gone, clogged or you need to extend a tad further.
This is for upstream or downstream sensor?
downstream of course
Always after the cat.
@@vehicfixwhat do you mean with a “ cat “ ?
catalytic converter
@@ivanmiranda7the MEAW MEAWW 😹
Is this legal in a state such as California or New York?
You’re gonna have to do some research on that buddy…;)
Will does pass smog?
once you do this, you reset and road test to reset monitors. if all is well then it will pass. if they TEST rear tail pipe and not just CEL then perhaps there may be a slight issue. But to combat that is to warm up the car prior. so if you are waiting in line keep it revved high to keep cat hot to work 100%.
I replaced both cats and both O2 sensors and I still get the same code again after a test drive and clearing the code what's with that
Sometimes cheap aftermarket parts are no good. Could be another issue as well I think engine coolant sensor or fuel trim rings a bell
@@lh98 ok thanks for reply Ill look into that 🤔
@@MementoMori-cs3se make sure you have no exhaust leaks near the cats too I was reading that any leaks within a foot or so of the cat can cause fresh air to get into the pipe and distort the readings on the o2 sensors. If you have a scan tool that can read live data that might help pinpoint things as well. Good luck to you
If there was a way to test the sensors, make sure that they are actually reading. it’s possible a wire might be cut a plug might be no good. You may have gotten defective sensor if the catalytic converter is no good usually won’t happen right away especially on an aftermarket one. It usually takes between four and six months for them to deteriorate.
@@vehicfix I purchased the sensors brand new, but from eBay should I get them from the dealer instead 🤔
I’d like to know how you learned this, and if someone showed you it then how did they learn this!
well 1st sensor measures dirty air, then cat then 2nd sensor measures clean air. So if you show clean air after the cat then the computer will see correct values. been a passed down technique i guess.
@@vehicfix I agree, can you confirm that it doesn’t effect gas consumption? Or any other problems to engine ?
@@gh.mustafaamin9457 I can confirm that it does not affect gas consumption because you’re not changing any of the settings you’re simply tricking the computer into seeing dirty air versus clean air and then it adjusts the values accordingly, but since the values are pretty much, the same, nothing is being compensated for other than seeing the clean air
@@vehicfix it work very well, thank you so mush for your guidance. ♥️♥️♥️
i have a test pipe installed on a 2007 accord. the guy put a non fouler on it but the light still comes from time to time and it runs rough sum times. any ideas on how to fix it ?
This bitch won’t make the car run rough. It could have a slight misfire which could be deteriorating your catalytic converter or the air quality and the sensor still might pick it up.
Is this cause engine issues in future?
If the cat is not clogged, you are fine
Does NOT work for upstream sensor wompwomp
It only works for the sensor after the cat downstream
Will it still pass inspection ?
if you reset the monitors and no check engine light, yes
@@vehicfix that’s amazing!! Thank you!
IF the cat is clogged,it makes the car run like shyte, so what would this do, you would have to straight pipe it.
Doesn't work on a lot of modern cars.
explain why?
Bruh i misclicked while searching i have no idea whats happening
Do you need a cat? I just got this code... the mechanic said you can drive your car, but will it f#ck it up if i drive it too long??? I dont want to cause engine problems... or is the cat for only emissions
If the cat is plugged it can cause problems. If it’s still free flowing to the muffler then it should be okay. All depends
Which 02 sensor do you do it on the upstream or the downstream Bank 1 or 2
always the 1 after the cat so it will see cleaner air from the front one tricking the ecu.
When your cat is near plugged it will make your car run poorly or not at all! Replace the cat!
If the cat is “clogged” then yes that it a totally diff issue. But then again, the car will be bogged down and you will know when it’s clogged.
@@vehicfix yeah my 300c was throwing cat numbers for a few thousand miles and the it bogged down an stalled. Cat’s failure is assured by 150k!
@@bubbafatas2588 yeah that’s understandable a lot of times I get a lot of customers coming in where the cat just deteriorates enough to just throw the check engine light on. So this fix helps people with that issue.
If you reset the codes and not drive long enough, you will not pass emission testing.
Those are called the readiness monitors
can not fixing it hurt the vehicle
You’re not really hurting the vehicle you’re making a temporary repair to pass inspection. Sometimes cats are still working good but may be a hair off to what the sensor wants to see.
I fkin hate that code
That makes 2 of us bro
You can buy them online with no need to drill. Whiners obviously do not have California cats.
Hi, dealing with a cali cat on an older Honda. Inspection tickets are adding up lol. Should I do this to only the upstream sensor? Or both?
I'd do both with a recommended brand according to the forums. And do it within 2-3 days. My code came back on the 4th day. Before that spent $30 on all the guaranteed to pass chemicals. If you're keeping the car forever. But I put the spacer on the rear 02; no more codes in months
tricking the computer isnt fixing the problem
Quickest way to mess your car up more . Got it ! 👈🏾😉
@@JaenesiaWilliams you sure about that?
That is not a fix....thats a low life thing people do when selling a car....just fix it right
Super illegal.
I have a Kia Rio 16 code p0420 will this help
False
You didn't show the proof that's the whole crux of this video if you don't show the proof and what you did in vain. useless nothingness gab gab gab is all you got
You tricked the computer but yet didn't fix shit still gonna run like shit just won't have c.e.l. pathetic . No wonder my customers want to do stupid shit like this to their cars. The reason that code is coming up is the convertor is not doing its job shortly will fail doing it this way
What is a temporary repair to pass inspection. Then you can make the repairs when you have the money to do so after the fact.
