How to beat a P0420 Code for $6 (Using 48 State cats on a California Emissions Car)
Вставка
- Опубліковано 8 вер 2024
- Today we will show you how to work around two different emissions related issues with one awesome trick!
Issue 1: You vehicle is throwing a P0420 Code (Which indicates that the catalytic converter is not functioning efficiently). In most regions having this code will prevent you from passing vehicle inspection. Don;t worry, this super inexpensive trick can help!
Issue 2: Either you live in California (or New York) or somehow got your hands on a so called "California Car". These vehicles come equipped with a different, more strict, emissions system. The parts to service these California emissions cars can be up to 10 times more expensive than the regular parts... But do not fear! We are going to show you how to use regular emissions components on a California Emissions car and keep the check engine light off!
What is the secret to solving both issues? Spark plug foulers!

Car could be from Vermont they have the same emissions requirements as California
You can split your exhaust into dual exhaust or a Y-pipe before it exits to the rear of the car, with a small restrictor plate hole inside to the rear outlet and they only stick the tester into your rear tailpipe and so most exhaust blows out off the pipe under the car, this yields a 50% to 75% reduction in measured emissions
That works. I did it for my 02 avalanche
your in CA?
Most northeast states, including New York and New Jersey, have laws that require their states sell “the most emission efficient variant of a vehicle available.” So if an auto manufacturer makes a “California spec” car, those northeast states are required to sell them. It’s been like that since early 2000s. Almost all northeast cars are California spec’d. PS- even that garbage can was rolling over when you floored that cold-start Subaru!
It’s wasn’t a cold start lol when I put the sea foam it was at operating temp lol it only sat for 10 minutes before that
Fooled me! Keep up the awesome content E!
Well I mean it is a Subaru the generally sound like they have marbles in them most of the time lol thanks!!!
It’s a great and reliable video. Was facing this kinda issue back then with my emission test so I had to look for a way, which was how I came across Stray Admin who has got years in experience of helping lots of citizens pass they’re Smog test too.
All I had to do was just to hit the UA-cam search icon and type in Stray Administration, he popped right after..
can't find his channel?
California , and all of the CARB compliant board States train their inspection
mechanics to fail a vehicle they see this mod on.
I'm not saying someone might get lucky ,
Not saying I agree with emission rules ,
but the chances of someone being passed while doing this is slim
if you live outside the rust belt states or western usa.
Much different rules here in the carb compliant northeast .
In the northeast , you fail for even the cel being on even for non
emissions reasons.
They don't play .
I have a 2012 Honda Civic and I tried to put a non foul around it just to see if the light would stay off but it still came back on that tell me? Does that mean it's something else tripping the p420 code and not catalytic converter? I also changed both oxygen sensors air intake hose PCV valve cabin and engine air filters and I'm still getting the code
Love the free harbor freight light..😂
You know what we do come on brotherrrrrr
Won’t the smog guy see the modification? And what size spark plug fouler?
It didn’t work.
California emission laws suck nobody knows that better than someone that lives in California you probably got a California emissions car because somebody from California move to New Jersey and traded their car in just remember Eric it's not California legal for emissions unless it has a California stamp on the catalytic converter no matter what the rest of the system looks like that's why when you go to buy the catalytic converter you can't just put any catalytic converter on the car in California. Unfortunately your modifications would never pass in California because before they smog test the car for emissions they inspected for modification
You talking a lot my friend but not giving the knowledge in which direction to head to buy some catts in California
Any website or shop ?
You can replace that cat with a federal converter. If you have a car not from Ca. and you move to Ca. you might need to replace them if they don't pass Ca. smog.
You only need to replace them if they dont work. If the car is a California Emissions car, it needs to have CARB compliant Cats on it. If Federal emissions, it doesnt matter which EFN code you use.
If you install a non CARB cat onto a CA car, will the computer detect isn't not a CA converter?
Yea. It doesn’t run as clean so the reading from the O2 sensors will tell the comp it is failed and pop a CEL
Do they not check for this at smog test?
they are checking now, really sucks
I did this on my 13 out back an got a system lean code instead of a p0420
The spacer created too much distance between the car and o2 sensor.
So...did this work as a ling term solution? Im in the EXACT same situation. Bought a Buick Enclave that has California emissions but i live in Pittsburgh. Previous owner replaced all 3 cats but I still get the P0420 code
Yes it should work long term. Defi Italy works well in Jeeps and Subarus indefinitely. Worth noting that you are tricking you computer, so you may not be making peak mpg or hp
Nice money saving tips, but did you know Mayonnaise can be used for anti-seize. A bottle from the dollar store will last for years in the shop,,,
You look like Ivan the Terrible from The Vikings series
Will this work for a 2012 Honda Insight I feel like it might be too cramped underneath
I wonder if this would work on a cracked manifold
I'm going to try it out so I can get my engine light off
Nice vid! Do you happen to know if it will reduce the NO numbers also? I'm assuming it would. I have no codes on my 98 4.0 ZJ and she failed.
It should, but this is an extremely low tech way to "trick" the computer. you arent actually solving anything outside of turning a CEL off.
@@DEInTheGarage thanks for the reply. Love the channel. I don't have a CEL, never have. Replaced O2 sensors and coolant temp sensor, now just trying to get the catalyst monitor to a ready state so I can have her tested again. If she fails I may try your trick.
Hell yeah, buck
Off subject yes, but a jobeeper question non the less. Any word on how to get the wj from electrical disaster and mis fire disfunction Everytime I go wheeling in the rain or wet, ?
Dielectric grease will help. Other than that, keep a set of throttle body sensor spares in the glove box
Also if your coil is original you boots could be getting loose letting extra water in then normal or cracked.
I'll give that a look at, thanks for the info!
You can compress clean exhaust gases from another car into a 5 gal air tank and then pipe that into a fake exhaust pipe for the smog check,,,
I'm wondering if this is legal here in AZ.
WARNING - this in theory works... but in california.. the smog check place is required to crawl under your car or use a mirror on a stick to make sure that you didnt install one of these foulers/spacers. you may pay for the smog check and then fail and go on a government 'blacklist' for doing this
I live in Cali and never seen them with all the cars I've had look or inspect under the vehicle....
I've lived in California and never had one tech crawl under my car, the last time I took my truck in 2007 Tundra the guy plugged his equipment into the OBD2 port for 5 mins while he drank a coke and handed me a my passed cert. Oh and I'm 55 grew up racing always looking for a way around.
I'm sure they check for irregularities , underneath the vehicle while its on the lift.
They might do it fast , but they check for everything.
I have a cali car in Nebraska straight from the dealer 🤦
THE SMOG TECNICIANS, IS CHEKING FOR THAT MODIFICATION
AND FAIL THE TEST,,IS THAT CORRECT? IT IS ANY NEW SMOG EMISSIONS
LOW RECENTLY APROVED ? I DONT KNOW,
That is highly illegal. That’s a $100,000 fine.
And which is the legal way ?
I need some catts since mines got stolen
ehh, as long as you aint in california.
What's a spark plug fowler?
I have a e90 328xi and my sensors fit inside perfectly. So I had a 420 and 430 code also so I took regular spacers and drilled the 1/2 hole through the fouler and installed it on both banks on the downflow. I reset my computer and did a drive cycle but the same codes came back so I added double spacers but this time one wasn’t drilled at all and the other one was but now it’s throwing codes for “no activity detected” on both banks 1&2 sensors 2. I’m not sure if I should put a single spacer (without drilling anything) or keeping both spacers but drilling a little bit though the spacer that isn’t drilled at all. I also have both of my CATs but for some reason it’s throwing codes.
And if you’re wondering if the drilled spacer is on the exhaust or if it’s on the sensor I have it in this order
Sensor-fouler-drilled fouler-exhaust pipe
Also the codes that said “no activity detected” actually went away for a good 50 miles AFTER drive cycle was complete. But only bank 2 came back I’m also expecting bank 1 to come back. So I’m thinking it worked a little but not enough. I guess I should probably drill each spacer a little bit then try again. In that time I completed my drive cycle and until the “no activity” light came back on I could’ve gone to inspection and passed emissions. So it definitely worked for a little then it stopped detecting anything
usually a 48 state cat will work fine on a cali car
Work ,yes ….pass ,no ….they check the cats number and if it doesn’t match vehicle engine family it fails on tampering….
It gotta match with the engine number or what you mean and where I can buy some catts legal any website or shop ?
@@mobb5014 yes and no. just get the fuck out of california. if youre in a epa compliant only state then you should be fine as long as you dont throw CEL codes, i think that counts as not passing if CEL is on. california is just super harsh with their emission like they check EVERYTHING.
I have the code P0430 will this work also
I emailed you all and haven’t heard back in 4 days
You can Facebook us too if you like. Sometime emails get lost in the thick of it.
Hope the epa doesn't see this video lmfaoooo ask the diesel bros about that.
Thanks, ,
How do you know which one needs the fouler ? I have a Subi with 3 converters . I was going to put it in the one right before the mid pipe to the exhaust system but should I go up closer ??
Jay Smith you go off the code your throwing. P0420 is bank 1 so it’s the first cat in the system
So what year is your Subaru?
Use a scan tool with live-data graphing, it will show which cat is dead. But 420 refers to the downstream sensor, so whatever cat is before that sensor is your culprit.
The last O2 sensor in the system behind the last Cat. The last O2 is the cat monitoring O2 . The computer compares the front HO2S's or A/F Sensors against the last sensor and monitors the rear O2 sensor activity. A good working catalyst will cause the monitoring O2 sensor to have no or very little activity after the cats light off. The computer is programmed to watch for the monitoring O2 sensor to be inactive within a specified amount of time. If the O2 is still active after that amount of time, the computer sets a P0420, meaning the catalyst has lost some of it's ability to do its job. Some vehicle manufacturers can reprogram the computer with an update to increase the amount of time it takes to set P0420. It's easier, less time consuming, and better for the car if you can check with your dealer to see if there is a computer update for cars setting a P0420.
Where can I get one for my 04 Ford escape?
Doesn't fix the problem, just masks it. Better idea is to just fix the problem! This is like putting gum on a water pipe leak.
In CA the only way to solve it is to buy another OEM catalytic converter. Instead of being able to buy one for a couple of hundred dollars, I am going to have to buy one for around $1300.
@@brianb.8681 I’m buying some magnaflow universals for my G37s coupe. Fuck paying 1000 per cat from infiniti! That’s bs. I’m getting them welded on. There better and cheaper. 500 for 2 and then 200 for my guy to do the job. That’s still less than half the reg price and for 2! So 700 for the whole job to get done or 1000 for 1. Yea I’m good. And it passes Cali emissions
@@swervv2957 works on that car but not on a bmw oem or else
No, it does fix the problem, because the problem is the stupid law, not the car..
Does anyone know if this still works?
yea, absolutely.
Yes I done yesterday
Or remove cat(s), install straight pipe where cats were, problem permanently solved....those cats really don't do what the EPA claims they're supposed to do, all they do is restrict airflow through your engine causing power loss, oh and expensive repair bills when they fail. A properly tuned engine will put off less emissions than a cat equipped vehicle will. My non-CA emissions vehicles have passed SMOG in CA several times, they give me weird looks but all I tell them is CA emissions isn't very good because my old 71 Ford doesn't have cats or any emissions shit at all, and its passing emissions....so...point proven, all the emissions shit doesn't do anything except not allow your engine to breath properly causing the emissions problems in the first place.
So your sayin if you can custom tune your car to not pollute the air,you can pass emissions in ca?
Why are you smogging a 1971 Ford when any car 1975 or older is smog exempt and also keep in mind each car has to smog for its model year
Gasoline 1976-present
Diesel 1995-present
@@AlcyoneModschannel You obviously didn't read my post.
I got an 04 mountaineer and it still threw up a p0420 even though the last owner removed the cat and replaced with straight pipe now the jury's out on what's wrong with it. I'll start with this cheat and move from there.
@@lavaoasisborrow from your family member or neighbors Explorer same year and engine if your lucky and swap it back after you pass 👌
