- How to fix you emissions p0420 code for cheap, easy, fast. Watch this video and learn how to turn off you cars check engine in under 10 minutes with parts available at your local auto parts store.
I would not have found this solution in a million years if I kept searching for conventional wisdom on UA-cam. You are the man! I'm going to try and address other causes of the code first, but regardless I appreciate someone who thinks outside the norm!
This is genius.. I was a little sceptical but tried on 2009 Hyundai Santa Fe with 175,000 miles. Next day, bammm monitors set and smog passed. Quick tip: I went to Lowe's and they drilled it for me so I didn't have to buy the drill bit. 😊😊😊
Legend has it he’s still finding ways around car codes as we speak.

Sometimes ya gotta do what is necessary... An a "Good Evil Genius" is jus what we gotta have ta get the Job Done!!! Thank You Sir :)
This tip "pulled my ass out of the fire." Back story: 10 months ago, my check-engine light comes on, code 420. This was a month before I had to have the 2-year emissions test. I didn't have the money. I ignored it. I got a letter from the DOT that my tags were suspended due to failure to get emissions tested. But when my tag stickers expired at the end of this year; I had to do something.
This worked for me....got me through emission testing....worked great! 2004 Toyota Camry, 2.4 L, 220,000 miles. Note that in my state there is no visual inspection beyond looking at the under-carriage with a mirror on a rod. My new installation was shiny; I roughed up the spark-plug-non-foulers with 80 grit sandpaper, dipped them in bleach and let them sit in the sun. This helped "age" them and make the modification not so obvious. Good luck to all, and OP, thank you...you saved me.
Edited to add: In my state, there is no tail-pipe test. They only hook their tester to the connector under your dash.
When drilling out the anti-fouler, use lots of oil to lubricate....it'll help to stop the drill bit from biting in to the anti-fouler.
Congrats, I’m glad to help anyone rip the system. Government gives people money that don’t deserve it and then takes the working middle class person who lives check to check and makes them try to spend their hard earned money for shit that doesn’t even benefit them, emissions is a scam in my book
Yes, I suppose bluing the anti-fouler parts would be a prudent move, keeping the "emissions modification" discrete. That stated, I went to a junkyard with the intention of picking up a used cat, for a sibiling, from a wrecked vehicle. The staff member informed me that it was against the law for them to sell cats. I told him, "some racket the state has setup." He nodded in acknowledgement.

It's TRUE.!!!
Did this on my 03 Avalanche, worked great for 4 years! But now I can afford to install new cats. Really helped me financially during tough years.
Why bother with new cat? Just keep on saving by doing nothing.
Does it have any effect on MPG than the covenctional cats?
@@AnythingEverythingGh well, would have to have at least a small affect because your vehicles computer is always watching the input from o2 sensors to adjust the air/fuel mixture to stay optimized as you drive. But I couldn't really tell a difference
@@cmongimme There is a notion that post 02's or rear 02's are used to check ONLY emissions with regards to cat performance whiles upstream is for fuel adjustments
@@AnythingEverythingGh absolutely correct! And sorry but I added those years ago and couldn't actually remember if upstream or down stream but I remember now it was for code of cats, so obviously downstream
Yea both those dudes nailed it. Totally works. 2006 Subaru Impreza 2.5i . There is barely any of my cat left and this worked.
And let this be said. Not all states and counties have emission testing/requirements. So this is a great CHEAP way to deal with a trouble code.
The other problem with that code is that many vehicle computers shut off the cruise control if that code shows up. If you drive a lot on the open highway (If there are any left) that is an important code to have eliminated.
Works great. No CEL now for over 1000 miles. No pending codes.
I read about this procedure in a Miata forum. My buddy does not have money for a new cat so.. we will give this a try. Thanks Daniel
Give him a fucking break guys, he knows it's cutting a corner, we all know that. That's not the point. The point is to pass emissions for guys who can't afford to get a new cat. Great video man that's a very valuable trick that I will never forget. I can finally do a cat delete and not have to get expensive O2 sensor emulators!!! Thanks so much man!
Dylan O'Connor thanks man I appreciate it, so much fucking hate on UA-cam now days
Daniel Bargas some of us people dont have 2 nickels to rub together at times let alone big money quick... Cheap get by til money saved for a fix... haters want to hate... let them... when they get down to one ramen noodle soup in the cabinet and no money comming in or verry little then they will understand how you are HELPING us skate by cheep... good shit brother and my thanks
I'm all for this...do u think it will work on 2005 astro van downstream ? I can not go for catalytic conv. right now
Dylan O'Connor amen brother I recently got the p0420 code and my cats cost $400 for a pair and I just going to try this method till I can save enough money to buy my new cats
What if they read the pipe exhaust?
I have a 2000 Honda Civic ex 1.6 liter..
bought for 600 bucks P0420 came up on scanner. Did this AND IT WORKED!!!!! DUDE THANK YOU SO VERY MUCH FOR SHARING THIS VIDEO!!!! YOU SAVED ME A BUNCH OF MONEY!!!!! And it was super easy!!! 🇺🇸🇺🇸🇺🇸🤘🏻🤘🏻🤘🏻🤘🏻

This worked on my gmc terrain. Thanks dude!
That's exactly what I was hoping. I just bought a 2014 and I've had it a week and the check engine light came on. I scanned it and it came up P0420. I was so mad because I paid cash for it and figured it was something bad. There are no symptoms that anything is wrong, but thanks to you I'm going to go ahead and try this. Thanks for taking the time and posting that it works on the Train.
Where was the sensor located? On top of the engine near the cabin or under the car? Haven’t looked yet just curious. I have a terrain as well.
Daniel,Thanks for posting this fix. No more PO420 code. The hardest part was actually drilling out the anti foulers without ruining the threads. I have a Blazer that has 2 cats and they were plugged. A new factory set up was over 1000.00. So I delete the smaller cat and replaced the main one with an aftermarket. Issue was the 420 code was coming still. The anti fouler mod fixed it and I am a happy boy!
Haha no problem just glad I can help others out who appreciate this and not just hate
Paying $1500 at the stealership doesn't HAVE TO BE the only answer. I was able to replace my Jetta cat with an aftermarket from Walker (about $100 back then) and it fixed the cat issue. Had a muffler shop weld it in for about $100 too. Worth looking into aftermarket converters to see if it will permanently and legally fix your problem.
06 Infiniti g35 with 240k miles.. WORKED LIKE A CHARM! Thanks man saved a grand$$$
Hey buddy after 2 years did engine light turn on again? Or you have any problem..? Thanks
I wanted to personally thank you for posting this fix. my 1998 Toyota Avalon had been throwing the p0420 code. My local repair shop wanted to charge me $800 for a new cat.. I told them to go f*** themselves. I went to my local AutoZone and picked up those non fouler's and went to my Menards and picked up a $10 brand new bit and it took about 5 minutes to drill out the non fouler. it was a pain in the ass to remove the O2 sensor but once I got it out and put the non foulers there it passed emissions with flying colors.
No problem and good luck, I have people who hate because "it's not good for the environment" and other bs but I'm glad I was able to help you
Thanks Daniel, you are helping many people who otherwise would not
Be able to pay thousands for a simple fix, keep the videos coming, thanks
Ignore the haters, peace.
abe jams no problem just finished a k24a1 to k24a4 swap in a crv with a guide and how to video
I have the exact same car and year, everything runs great but this cat. Glad to see it works on this car.
After you did this, did you get the code? or was it gone?
Thank you!!! It worked! Had to use the steel wool because without it the light came back but the car just passed inspection!. YAY
Thank you....Saved me hundreds of dollars. Honda Civic

great video, some folks without the resources to outlay that much money to replace a catalytic (which by the way should outlast the life of the car, it is made of stainless steel). Great way to keep the car on the road allow those folk to get to work... etc.. thank you for this video.
just did this and passed smog thank you. If you guys still have the check engine light on take off the negative terminal, drive it around for 60 miles and then go 55mph for 5 mins to reset the catalyst incomplete code.
This 100% worked on my 2003 Honda Element
Just passed CA Emissions test.
BTW drilling the metal non foulers is a lot easier with it clamped a drill press and a stepped drill(Unibit)
SmallEngineRepairGuy uninitiated is the best way
Unibit
Did you have to use the steel wool? I just used it on my 05 accord and haven't got the code but the catalytic monitor mil is still flashing and not ready on my obd.
Worked for me on a 2016 Honda Pilot. First reset your engine or unhook the battery. After that drive it for around 120-130 miles. The check engine light will come back on at 50 miles, but keep going to around 120-130 miles. Just passed smog. Thank you for this post
Just did this 12 GMC terrian. And it clears my issued up. I had to use the steel wool. But have no issues now.
This absolutely works! My check engine light (P0420 code) has been on for the last year and a half. My son put this on, we had the codes reset, drove the car for 100 miles and the check engine light never came back on. Got my emissions test today and I passed. Had tried putting all types of cleaners (seafoam, redline cleaner, Lucas fuel injector treatment) and none of them remediated the light. My son had to drill the hole a little larger than stated in the video to fit my O2 sensor and we added the steel wool as mentioned. I have a 2009 Nissan Altima with186000 miles and I passed emissions thanks to this!
Check engine light still off?
Light still off and car still passing emissions testing by state of Illinois
@@marydistler5269 shit I'm in Cali where they are hard asses about everything. Fingers crossed I will try it and keep you updated
So it passed emissions for me but now the light is back after a week .

Just did this for my 04 Jeep GC and worked liked a charm. Now it was raining and they didn’t inspect underneath the car like they normally do or I think they could have seen it, but anyway it passed and thank you!!
They'll getcha
Appreciate bro you saved my life,been trying to fix this code and after looked your video and try it just runs the truck for 150 miles and today pass the inspection sticker. (I tried after running for 70 miles and doesn't shows nothing so I have to running for 80 miles more and buala!!! Thank you so much to share this videos.
Young man if you still monitor this video, thank you it worked.
Jeff Hicks what kind of vehicle did it work on for you.
U sir are doing gods work ! LOL! Thanks for the how to and very well explained! LOVE IT!
This will also work if you have an aftermarket high flow catalytic converter or straight pipe installed.
I can confirm m18 anti foulers drilled to 1/2" thru hole will clear p0420. Worked beautifully
Is your code still cleared?
@@santinootero8270 yup
I did the trick and I passed emissions, but a week later the same code came back idk wtf .
@@santinootero8270 Did you figure out what it was or another solution?
@@TheWorkBench I got it to clear again and it's been off since I added a little more steel wool on it , thank god it's good for now
I did this to my 2004 tundra in 2016. It is now 2020 with no problems. A bad CA cat. Works like a charm.
My cat seem to flow pretty freely on my 2001 Sequoia. But I'm getting this code. I guess they're just not efficient anymore. I spent $600 on some MagnaFlow Cats. Now I'm reading how they throw this code regardless with MagnaFlow cats. I think I'm going to return the cat tomorrow and just buy me some damn non fouler's LOL.
The bottom line is this fix works!!!...Great job dude!!
Will the check engine light go away to?
This worked on my 1996 Blazer today. Thanks Daniel!
Still good?
Still working? It’s impossible to know in one day if a fix like this was successful. It usually takes 60-100 miles for the sensor to trigger a cel after you clear it out
@@youtubeisbroken241 I know. Most people say it came back after a few days. But I can't get any answers from people that say it worked lol. So now that it's getting cold I will give this a shot.
spafro101 I removed my o2 sensor and sprayed half a can of seafoam in and then replaced the sensor and ran my car outdoors till the smoke stopped. Not only is my code gone but the car doesn’t stink when I get on the thruway like it used to and i gained some power back. Sounds like a better fix than this. This is just tricking the computer and does nothing to get fix the reason it threw the code. It should keep the code away though if all you need is to pass inspection. I had the option of trying this but decided to try cleaning the cats with sea foam and I’m glad I did because my engine runs much better.
Thank you SO much!! This is a HUGE help!!
Great video!! Thanks for the tip!! ✌️
You do not need steel wool.
Awesome video. Thanks a lot.
I was wondering about the steel wool, thanks for this comment 🙌
This worked on my, err, a friend of mine, 04 Honda Civic. Saved my...err, his a$$. Thanks Daniel.
Glad you fixed your honda brent
Here on Maryland after reseting the light , I cranked engine and turn off at least 20 times , and immediately took for emissions , guess what ??? PASSSED my 2 cars , my daughter ,and a friend car !!! …..secret ??? So simple ! CYCLING KEY !!!
This trick worked for me. 2000 Honda Insight. I still plan on replacing the catalytic converter because emissions do cause health problems in congested areas. It was a pain keeping the washer from falling on the threads when I put it in the cat so I put a wire twist tie around it and tightened a rubber band around the trailing wire. Then made sure to take the twisty tie and the rubber band off so it wouldn't burn up.

Agree that engine Light it doesn’t come out but if you’re in ca it doesn’t pass the smog I experienced that
for your trick worked on my vehicle. so thank you it is much easier than doing what I would do to fix it. and no I wouldn't wash it cuz that's not my issue my Cadillac converter is good it just needs to be rewrapped and to do that you gotta take everything off which I would do once I have more time that is a long process. so thank you once again.
Thanks bro!!! I did everything exactly how you explained and my light never came back on and I passed the retest here in Cali!
Hi there. After installing that part does the check engine light disapears by itself or you erase it ? How do you erase it ? thanks
Love the attitude 🤣😂
Brilliant!! $6.29 screws the dealer/ manufacturer. Thanks!
p.s. I don't think you need to drill the spacers on German cars.
Haha no problem, not sure about German cars, drilling the spacer is required depending on o2 probe length, for the 10 or so cars I did it on I had to drill them all out
I have a vw golf , would I need to was the drill on the spacers ?
Thank you. It worked great.
I'm not from Cali so I couldn't say but I don't see why they would and if they do just go to another service shop, some places are way more particular than others so look for a just basic corner shop not some place that's going to do some crazy 400 point inspection
Nope, the machine catches the code not the mechanic and his leniency. They all use the same machines for state inspections.

almost a million views, impressive, good explanation 👍
Impressive ??? What about the environment ? Tank you very much I don't have P0240 code anymore.Make me depressed...
It works I have a 05 taurus with 4 02 sencors did both downstream and passed today
Sweet!
Excellent craftiness, and if others are having issues with the aluminium and need something more robust; various brands make O2 sensor bung extensions just for this exact reason at varying lengths and in steel material. An alternative would be to wire in a O2 sensor simulator, that mimics the proper signal to the ECU, but some of these tricks may not work on newer models that utilize a wide-band oxygen sensor, but most older stuff for sure.
How do you clear the code?
@@joebyu Use a code reader and plug it in to your OBD port under your dash on the left side. Follow the prompts and follow them closely. When you get to the part that states "Clear codes" or "Do you want to clear the codes?" hit yes or enter. Mechanics have them or get one on the internet for about 50.00.
Or disconnect the battery. If you have a Dodge, you don't have to have a code reader. Turn your ignition to the furthest point. Don't start it. Do this three times. On the third time, the code will come up in your odometer (digital).
Qué chingon! You kick ass man!
Worked perfectly for my dodge stratus 2004
Plus I removed that f catalitic converter
did your gas mileage go down though??
He raised my anxiety level with the one-handed video shaking, but I'm gonna try it.
Very interesting; I've seen this done on vehicles that were being experimented on with a brown's gas kit in order to fool the computer. One thing to bear in mind - the problem could be a plugged up catalytic converter, and fooling the computer to pass emissions inspection won't prevent it from ruining the engine.
Ruining is a strong word. A clogged cat, even a severely clogged one, should only affect performance of the engine. In an extreme case, one could argue higher temperatures developing for the exhaust valves. But that would likely only happen after years of being clogged. I have seen that with crushed tail pipes. But that’s a major restriction compared to a clogged cat
maybe it will lead the cylinder misfire
@@youtubeisbroken241 high exhaust pressures can definitely ruin an engine seen it over heat Diesel engines and cars
Dude I passed emissions!!! Thanks
It worked on my 2009 Buick Lucerne I just won from an auction! Laquer thinner didn't work, sea foam didn't work either. Thank you!
I'm going to try the "cat clean" stuff first, with some '91' gas. If that doesn't do the trick, I'll be under the car getting this trick done. I thank you for this info. Getting the codes cleared and getting the inspection done is a big hurdle for those of us who don't have a fortune to blow, and I know I'm not the only one who appreciates it.

Thanks so much for the help!!!
Kenton Friesen no problem
OBD2 code p0420 doesn't necessarily mean your catalytic converter is bad. Actually your cat should never go bad and should last the lifetime of the engine. The only reason they ever need to be replaced is because there's a problem. Even if 🐈 is internally FUBAR, (clogged) you can just gut the 🐈 and weld it back on. This way is probably much easier but I sometimes you got to do things the hard way. LOL good stuff BTW
Catalytic Converters last the life of the car - that is until it is stolen off the car.
Thank you for showing this video. I am one of the guys that can't afford a new catalytic converter, so I am going to give this a shot. Why not. Right?? I hope it works for me. I will let you all know if it does!!!

Worked for me on my Cadillac CTS thank you
thank you, this is a perfect fit for my truck as someone "stole" my catalytic converter! lol
Is this permanent for sure? I’ve cleared code and passed emissions but was curious if the non foulers will ever need to be replaced or will they always work for the emissions tests in the future to come? Thank you @danielbargas
Drill a nice hole through the catalyst. Then do this. That way you're letting the exhaust work if the cat is clogged. And no code.
p0420 is not a clogged cat
It often times is in fact a clogged cat. I know this because it happened with mine.
My '99 cr-v was a phone call away from the scrap yard... serious lack of power, engine light always on (p0420) and could barely go over 35mph (downhill with a tailwind). I knocked out the front cake of catalyst, which was really plugged up, soaked the rear cake of the catalyst in soapy water and used this little trick on the downstream CO2 sensor... just took a test drive and the thing is running better than ever before. Thank you for sharing. :)
Scott Carney no problem glad I can keep another car running
works for me thanks man
For those complaining that this causes smog, you have a point, but it's not as bad as you think. The CEL comes on when the cat drops to 95% efficiency which is a pretty high threshold. Spacing the O2 sensor back might stretch it to 90%, so just a little more smog in the air, not like it's a 1970's polluter. If you do this hack and it doesn't work, you've got other problems, a vacuum leak, leaky injector, bad coil, up to and including replacing the cat.
A bad ignition coil was to blame for me. Cylinder misfire sends unburned fuel/air mixture right on to the cat. Coating it, making it less efficient. I am going to try cataclean, 91-93 octane gas, and a long trip on the interstate. If that don't work, I will try the oven cleaner in the O2 port hole. Then the spacers if them don't work. Before I buy a new cat.

This really works. I have a 2001 gmc sierra and I tried it. I figured I had nothing to lose. I tried it and the monitors ran. I went and it passed emission with no problem. Ps it only cost me 5 dollars because I had the drill bit
Its bs because in NY they can charge you 400 to "attempt a repair" and you pass, and if the conditions are right you can certainly pass with p0420. Just set every other monitor. If you get to the shop before the next drive cycle finishes you pass.
Thanks man I did this to my Audi you save me $3,000

What size
"Dont cram it in there so it can't sense shit" 😂🤣 haha had me busting up. Nice thorough video on how to escape the nightmare of not being able to pass smog.

Righteous video bro thank you. I saw a guy on here that was going to spend his customer's money on new spark plugs saying that the spark plugs were burning too hot because they're old one idiot I'm sure that your video will help me get through this 420 code.
I tried your method to troubleshoot if the CC was my problem. On a 2001 Chevy Express van the O2 sensor is too big to fit into the non-fouler coupling, even after being drilled out with a 1/2 bit. Even if it had fit, there wouldn't be room to screw it in because the CC is too close to the frame. This is for anyone trying your method on this model vehicle, and thank you for posting this video.

One of the few times 420 is a bummer.

Ayeeee🔥
I did this on my audi s4 with gutted cats, except I only used 1 adapter to get the sensor out of the stream. No code, like 2 years later. Also, what I think he's trying to say is that the upstream and downstream sensors look at the 'difference' of voltage between them to determine if the cat is not functioning properly. Obviously in my case, I had NO cats, and therefore the sensors would read the same voltage, meaning the computer can figure the cat is gone. On the flip side, if one sensor reads lower voltage and one reads much higher, the computer thinks the cat is clogged, or there is another problem. In some cases, it may be a bad sensor, like my truck with 300,000 miles. Don't totally rule out a failed cat, but usually they don't stop catalyzing, they crumble and clog. That leads to poor performance and terrible fuel economy. Plus, you should be able to hear your car struggling as it sounds like a prius when the cats are clogged. Not to mention the extremely high temps under your car, and possibly glowing exhaust tubes. You may even get lean/rich codes or other codes that are caused by a clogged exhaust but don't seem to make sense right away.

Mix in a paragraph or 2... Holy fuck man.
Worked for me...Thanks
It worked for my 01 4.3L . But..... the 1/2" drill bit did not work. I had to get a 32nd" larger, and use a drill press to drill it out, leaving the wall of the adapter very very thin. So far so good though. In Atlanta, there is a serious debate about ending the emissions testing requirements. Only 4% ( as per a news cast I saw) of vehicles fail emissions, and our air is cleaner now than when there were far fewer cars on the road in the past. The old saying "they dont build them like they used to " does not hold totally true anymore. "They" are built better, cleaner, and more efficient than ever. Tax hawk groups are claiming the whole system is just a cash cow now, and has basically no effect on air quality. I would not be surprised if emissions requirements are ended here in metro Atlanta, and maybe other cities can follow.
Hey Daniel I was wondering will it work for a 2001 Honda Civic and will this piece pass smog
Title of this video: How to scam the vehicle emissions scam.
Unless you are paying for my catalytic converter, this video is very good
Emissions testing is the REAL scam. Motor vehicles are only responsible for 5% of greenhouse gasses. But keep believing the virtue signaling left that sell the lie internal combustion engines are killing the earth. It couldn’t be third world countries who produce our trinkets 🤔🙄…..
Does the emission test only check the code or analyze the exhaust substances? If only the engine code is checked there is more simple way, one or 2 resistances wired to the O2 sensor can do the cheat.
@@jamesdon2052 In most west coast states they have OBD 2 testing which consists of a plug in diagnostic scan along with gas cap evap testing. No tail pipe emissions are tested unless it’s a diesel
They are scamming us into buying a new car, they could really get cars more efficient but who bribes the government? Fossil fuel corporations ,that's why they create fake wars for oil and they care about inviromemt?
Nice video , I did it in my 2007 nissan altima and get much better gas millage , before the extension 315 miles with full gas tank , after , 410 miles with full gas tank
Glad to hear, actually it doesn't improve gas mileage it restores it, gas mileage drops when a engine is in limp mode running extra rich to avoid potential damage, it you turn the light off wallah factory gas mileage is restored. Anyway glad to hear you had success
Check your fuel trims, George, to make sure it isn't running lean. That would be bad. What was your mileage before light on??
nice tips. Will have to try it and let you if it works for me. I replace to upper cats with walker cats about 3 years ago and now I’m getting p430 and 420..
Watch my video on this same subject. You don't need the washers, those are radio arresstors. They are to prevent the spark plug from interfering with your radio. If you were using the adaptors and washers, like they were used on spark plugs way back, they would help to avoid an RF static on the radio. You are not using them on spark plugs.
Also, you don't absolutely need to drill them out. I have one of these on my Altima for over 3 years now. Not drilled. No washer.
What are you talking about
The adaptors in your video were originally made to prevent spark plugs from fouling with oil on worn out engines. The rings/washers were to prevent static interference on nearby radios and tvs. Of course these days that's not an issue. They also act as a seal for the plug. Or in this case the adaptor.
Does that answer your question? Or were you asking about something else?
those are washers to seal the non fouler!!! there are 2 types of spark plugs one type has a tapered seat that seals the plug and the other is flat and need the washer to seal the plug. has nothing to do with rf static.
Scott Prado what is the link to your video. this code will kill me one day
Exactly Scott Prado, they are tapered seat seals. Because that model of non fouler is to fit tapered seats spark plugs hole
