*This video is an EXPERIMENT I wanted to try on my car, and is for INFORMATIONAL purposes ONLY. This fix is for off-road use. The content shown in this video is not intended to encourage emissions test cheating. I enjoy the process of testing theory because you always learn something new, regardless of the outcome.
Using a spark plug defouler kit, I install a "buffer" in between the downstream oxygen sensor and the catalytic converter. Quite often, frustrated car owners get the P0420 code for reasons other than a bad cat. I have heard of people getting the code just because they removed the converter and reinstalled it. It can also happen if you run your vehicle out of gas etc... etc...
It is also common for car owners to get the P0420 code, replace the converter, and both o2 sensors-- only to have the code come back after 1000 miles or so. This can be a very frustrating, time consuming and of course-- expensive venture. Here is one way to resolve the issue. Good luck and have fun!

90% of the cars I've seen with a catalyst inefficiency code had bad downstream O2 sensor, NOT a bad catalytic converter (cat). The ones that did have bad converters had bad upstream sensors and were run that way for months and the rich mixture burned out the cat. I always try changing sensors 1st, then the cat, as if you're gonna change the cat, you'll want new sensors anyway to prevent burning it out. One customer was told by the Volvo dealer that he needed a new cat for $1800. 88,000 miles on the car. We changed his upstream and downstream sensors (probably only downstream bad) and he passed emissions for another 10 years without changing the cat! Saved him $1600 and all legal.

I worked on mostly Euro cars and I tell you what, they lose translation from left to right hand drive. The Euro cars mainly Italian had and think still have a lot of electrical issues, but fun to drive when going well.

+Mouse Toad Thank you for your comment sir. This is important info people need to know. You need to diagnose and troubleshoot, rather than "shotgun" -- which many "automotive experts" fail to do, because they want to make money. Many times a $2,000 repair is actually a $100 repair. I hate to see someone on the $2,000 end, having to scrap it for a month or two because a mechanic was greedy and wanted to take advantage of a customer. Thank you for watching.

@chrisd8837 9 лет назад

What this does is basicly increase the difference in the reading of cat flow. When the upstream and downstream O2s do not see a difference in flow it sets a code this would be caused by a worn out cat flowing too much not a clogged cat. I can easilly see how this can work, I'm gonna try it on my 04 Jeep Wrangler 4.0l with a PO432 code.

Also my biggest point here is this is a waste of Time and money and if anything will make your car run worse because I see plenty of cars where people try to fix things on they're own and in a lot of cases just makes things worse. Automobiles are very sophisticated there is a lot going on and every part has a domino effect on the other parts and things like poor maintenance and poor backyard type mechanics might save you a few bucks but they just know how to change parts maybe even fabricate..

@uriel0002 9 лет назад

Very good video it works as long as you have all the tools at home other wise you'll spend lots of money buying them otherwise you can get a cheap cat online for about 130 dlls it I'll help you to get it inspect it I believe they last less than a year since the original cats are sometimes more expensive than the car itself if you do this trick don't go with assholes to inspect it that might make you fail for this do it with someone that you trust besides the cat stills work not to 100% but it does just like old people don't take me wrong just to give you an idea and remember not all the states make emissions Inspections.

P0420 is a universal/global fault code on OBDII systems that is specific to your CAT converter "Catalyst System Efficiency Below Threshold " or something to that effect.It simply means that the CAT is performing below a preset standard for this application,it could be off as little as 1-3% and still give the code.So this is a valid workaround for that problem,if you are not experiencing any other faults.

@mtpratt3294 10 лет назад

I have a nissan Frontier that has/had numerous check engine codes. The light was always on. I researched on found out that Nissan's have a problem with insufficient grounding of the ECM. To check this use a voltmeter and test the voltage from an engine bolt to the negative battery terminal. The voltage should be less then .025 volts (mine was .25V 10x out of spec). If it is bigger your engine/ecm isn't grounded well enough. To fix: add an additional ground wire from and engine bolt to the negative battery terminal. Problem will be solved.

Hi there , i'm working in exhausts and emission controls fixations more than 5 years ago and to tell you that , this video possibly could solve 20% of p 0420 conditions , what if you have problem with injectors or fuel pump or ECM , or clogged cat ?? that wont work, to simplify p0420 , its a reading between 2 sensors on a same exhaust line monitored by ecm , upon the demanding frequency of rear sensors the ecm will adjust fuel ratio to air on each combustion cycle ,but if you have electrical ground issue your sensors might stop

you are wrong , exhaust leak will issue " system too lean " p0420 is far from your point , its like 2 gates and 5 players must pass those 2 gates , but there many dangerous on the way between the 2 gates , so in normal conditions the 5 pass 1st gate and only 2 reach the 2nd gate , if the 5 players passed 1st gate and then they passed the 2nd gate all 5 of them means the way between the gates is useless and the game is over

Great Video, please share more of these hacks, Inspection time here in Texas is a bitch, so many times one cant afford the repairs necessary to pass and its not like you can just stop driving. I opted for owning old classics, instead of the modern cars just for this reason, once the engine light comes on you better pray you can afford the repairs before your tag is out otherwise you get pulled over and ticketed. Real stupid shit if you ask me, ..one rocket launch, satellite launch, nuclear waste spill, oil spill - is thousands of times more destructive to the environment than anything a car can dish out, but its a great money maker for everyone involved except the hardworking car owner. Please share more stuff like this, this is good to know, thumbs up bro!

@moccina 10 лет назад

In my state it goes by birthday month. How does it work in TX ?

@fordcobraboss427 10 лет назад

It seems to be tied in to the date of the initial vehicle registration, in my case its at 3 months after the registration tag date. I wish the emissions testing laws were more lax. id rather just pay a one time yearly fine and be on my way than have to maintain a vehicles engine in top shape over a few gases. Its all part of the bigger picture, bring in business for the Dealerships and Banks, most people rather be stuck in perpetual car payments buying new cars every 2 -3 years than face the repair bills that result from mandatory emissions laws. So much for Freedom huh. Makes me sick!

@moccina 10 лет назад

Ford Winsor SVT I agree-- buying and financing a brand new car is one of the worst investments one can make. Even buying "pre-owned" and financing is slightly smarter. I Financed my current vehicle but I put like 70% down and the total price for the car was a little over 5k so my payments are super low.

@shanonbull8279 10 лет назад

This won't necessarily make the car pass inspection, just possibly keep the check engine light from coming on by fooling the computer. All this does is move the oxygen sensor out of the exhaust gas stream to prevent it from reading the actual gas content. He did SAY this was for off road use. I suppose he will trailer the car to the edge of the woods. The auto can still illegally pollute the air, even without the light coming on, kinda like just removing the bulb.

@fordcobraboss427 10 лет назад

I understand the initial intent to reduce pollution but I think we should all be given a bit more leeway and not have to stress over Inspections as much until oil spills are non existent, nuclear waste stopped from seeping out of expired facilities, fracking by product gasses and water contamination eliminated, depleted uranium and other chemical toxins removed and no longer used in war, until at least these things are taken care of first, the pollution from vehicles is the least of our worries. Consider also the deliberate carcinogens and chemicals used in our food products....Those things should be the real issue. Vehicle inspection is a clever way to keep the sheeple buying newer cars, taking out vehicle loans etc...I'm just saying the tolerances for the emissions test are to narrow, they need to give us some room, not everyone has the $$ to have their vehicle in top shape, I wish we all could but that's is not realistic, its unfair.

@moccina 11 лет назад

Just to clarify-- If you have recently reset your ECU by way of battery disconnect, it will indicate a status of "not ready" to any OBD test until the car completes a certain set of driving patterns. Once complete, your ECU will indicate a status of "ready". If at this point the CEL does not return, your car can now be brought in for inspection. You cannot fool the test by simply unplugging the battery-- it won't work! Thanks for watching.

@AandWProductions 12 лет назад

The "P" in the code stands for Powertrain, meaning the code has to do with engine and transmission components. A code starting with "B" would indicate a body code and "C" for chassis. I would find out what's causing the P0420 code rather than masking it. Normally, it's just a bad O2 sensor or burned wire.

@poptrunkonu 10 лет назад

Ok that maintenance required light was on because It's a reminder for the oil to be changed and the code u erased p0420 means the cat is either stopped up or no longer working correctly and has to be replaced even if u changed both oxygen sensors the problem will still persist because it has insufficien flow so this rigged up u did will not fix the problem

@Edgeworthian 9 лет назад

Actually, depending on how the computer is programed, this will "fix" the problem. I have seen this done on a 96 Chevy V8 with a hollow cat, and it has worked for the last 75,000 miles. It depends on the vehicle. New vehicles, especially high end, are so sensitive that this doesn't work. If the computer is simply using the downstream sensor to check the CAT, and it's looking for a flat O2 level, then this trick works. Some vehicles (not sure complete list but I know it includes some Cadillac, BMW, and Mercedes-Benz) actually use data from that sensor to fine tune Air/Fuel Ratio. My buddy tried this on 07 Cadi V8, and it worked intermittently. I bumped into a C230 in a shop, had one in it, but was still throwing P0420. Yes, for off road use only, as this is legally tampering with an emissions device. It's a violation of the EPA Clean Air Act.

@bait28 7 лет назад

ummm.... you realize the sensor that the code is caused by a sensor reading the cat is bad, it's possible the sensor is also bad, just like when your coolant sensor fails and it is always pegged cold or your fuel level sensor fails and pegs empty, doesn't mean it's right. So it can be the sensor to. and no kidding it's rigged up, it's so he doesn't spend 1200$ on junky emissions crap!

@EMcKelvyF 5 лет назад

If you're running a test pipe, yes this does fix the problem. It prevents limp mode and some misfire issues because it keeps trying to adjust lean or rich between the two sensors. Obviously you can do a downstream O2 delete but this is better if you plan on getting a high-flow cat in the future and wanna keep that sensor without burning it up.

One question-how did you get your car on it's roof to check for leaks? Ha Ha... They use battery powered Sawzalls to steal the convertors by me. 5 minutes and they're gone. Walk in through the woods and crawl under the far side of the car. You don't even see them. They also steal a lot of outdoor AC units. 4 at the company I work for. They stole a huge one off the roof of an auto repair shop near where I work, too.

@moccina 11 лет назад

I appreciate your input. Whether or not this trick should be used is subjective. If the cat is actually clogged, you don't have many choices but to replace it because eventually it will cause damage and one day the car just won't start. IMO, the fouler method can come in handy when the CEL is on due to the cat being slightly less efficient than when it was new--but not clogged, and you can't justify the cost of replacing it.

Do you think that it may be related to the O2 sensors? or its just my bad luck that the catalytic converter has failed 2 days after i replaced o2 sensors?

@moccina 11 лет назад

I can't take credit for the idea, but I'm glad the vid has helped you :D

@moccina 11 лет назад

It's called an 02 Sensor socket and it's actually very handy when you have a rusted frozen sensor allowing you to use a breaker bar for leverage to "crack" it.

@GreaseMonkeyInc 11 лет назад

Wow......you have cleared nothing p420 code means your upstream sensor is reading the same as the downstream sensor. .... what dose this mean .....the cat is damaged/worn out by adding the " buffer" you pulled the sensor out of the exhaust steam you still have a bad cat shit like yhis don't fly where I from but yoy got almost a million views

@mrdan322 11 лет назад

It also means that taking it to mechanics like you will make you a bunch of money which you could possibly get for doing a cat converter change. Which it probably does not need. Watch the Scotty Kilmer idea of how to clean a cat converter.

@GreaseMonkeyInc 11 лет назад

A p420 code means that the two sensors are reading the same. Meaning the cat is no longer working correctly or the engine's exhaust is high in hydrocarbon ( unburnt fuel) and the cat can't process the hydrocarbons. This is why there is two sensors one before the cat and one after to measure the difference. If you live in an area where they don't smog/emissions test more power to you go ahead and remove the cat altogether the engine will breathe so much better.

@FarAboveDaCloudz 11 лет назад

GreaseMonkeyInc ...You are absolutely correct. It's just the cheapskates that don't want to fix the real problem (replace the cat after isolating and fixing the real issue that caused it - unmetered air intake, crack in exhaust manifold or other exhaust plumbing, injector stuck open, oil consumption...etc - that think all mechanics are theives. Perhaps we should return the favor and go to their place of employment and request their services then tell them they're full of it. Kudos to you!! The only time I've ever seen spark plug foulers used was at used car lots to conceal the truth. Wait till the clogged cat ends up burning a valve lol...And by the way, did you notice that the jackass that posted this never mentioned drilling out the center of the plug defoulers? What a joke!!

@mrdan322 11 лет назад

mrdan24 I live in a place where that is not an issue. But after removing the cat the check engine light will still stay on. What do you suggest to turn it off. ?

@SuperTurboDiesel2 11 лет назад

One last thing... you do NOT want to do this mod to either/any of the upstream o2 sensors. The UPSTREAM o2 sensors are the only o2 sensors that DO have a direct effect on the fuel trim (air/fuel mixture ratio) of your vehicle's engine. You'd be better off with unplugged o2 sensors, because although your CEL (check engine light) will be on, your engine will remain in "open-loop" mode, meaning that your fuel injection is controlled by a pre-mapped fuel mixture program in your vehicle's computer.

@DavidT811 10 лет назад

FYI the secondary's O2 just makes sure the cats working properly, nothing to do with fueling.

@enterBJ40 11 лет назад

so : by adding this sort of socket to your oxygen sensor you increase the distance between the sensor probe and the heated gases from combustion? i just don't understand how by adding this two pieces of ,lets call em "pipes", the O2 sensor stop problem.

@robertyoung7544 8 лет назад

YUP!!! This worked on my 2000 Honda Civic. But I bought a 90 degree Angled spacer from eBay for 20$. Spent half an hour under my car, replaced, reset codes, drove around for a few days(to and from work) and went for a smog and passed!! CEL light still off.

@madmac66 7 лет назад

Robert Young cool. I'm in the same boat. Was wondering if it just cleared CEL or actually passed smog test too

@moccina 11 лет назад

It should be universal. Check with your parts dealer. Thx for watching!

@Riprappotato 7 лет назад

this may remove the engine light but now your ecu cannot get an accurate read on the exhaust gas so your probably running rich or lean all the time

@jeffdarkness666 7 лет назад

untrue, it leans it out a tad & ONLY use this trick on after Cat 02 sensor, it won't hurt a thing in fact it Helps a bit both in Gas mileage & performance, its an old trick.

@Riprappotato 7 лет назад

Jeff Darkness okay cool i will try it out then

@jeffdarkness666 7 лет назад

cool, I think you'll like the results.

@scottdiamond74 7 лет назад

It won't do shit.

@madmac66 7 лет назад

Downstream sensors do nothing more than report emissions data to the ECU. The upstream sensors control your air/fuel mix which determines how rich or lean your engine runs. Obviously your upstream sensors need to be working well to keep your engine running well and this mod is only for downstream sensors.

@MrNotorius5500 11 лет назад

For those of you who didn't use google, P0420 means "catalyst efficiency below threshold. The downstream O2 sensors are reporting to the PCM (computer) that there is excess oxygen in the exhaust because the cat is not burning it all to reduce emissions. By installing non-foulers in-line with the sensors, it reduces their exposure to the exhaust gases and therefore makes them send lower readings back to the PCM. This rig will not affect the engine in a negative manner.

@davidflores-xu3wr 6 лет назад

P0420 it means you have to blaze it

@moccina 11 лет назад

I appreciate your point of view V8. This video in essence is a documented "experiment" of mine. It is purely informational; intended for off road use. With that said, it has been proven to work time and time again. In a perfect world, your mechanic will know exactly what to do, and which part needs replacing. Unfortunately even dealerships will resort to the "shotgun" method, replacing every possible culprit--only to be left with the code remaining, and a huge repair bill.

@BigBrotherIsTooBig 11 лет назад

@RealLifeProductions 10 лет назад

On my 03 altima i didn't have to do any drilling. And I only used one spacer. I screwed the spacer into the downstream cat and then screwed the 02 sensor into that. I didn't disconnect the battery either, although I agree that's always a good thing to do when working with electronics. Then I cleared the code using my reader. No 420 code for over a thousand miles so far.

@Parvss 7 лет назад

Scott Prado Hi How did you clear the code with reader?

@RobertWWilliams 11 лет назад

I used this method by the book and 3 days later the light came on again. (sigh)

@carlossantiago8321 4 года назад

Long idling time triggered my Work truck. i cleared it again and avoided prolonged idling hasn't been back.

@salamaa3613 9 лет назад

which o2 sensor you opened ? the first one from the front or second ? please.

@Bradjgonnuscio 8 лет назад

check engine light went out because you disconnected the battery

@mersudinomerovic9967 8 лет назад

Bradley Gonnuscio so true lol he's an idiot

@moccina 8 лет назад

You didn't watch the whole vid. I added an annotation at the end showing the CEL did not return after 5k + miles. I addressed both the CEL and the MRL seperately in this video.Thanks for watching.

@toddulrich2 7 лет назад

it was probably from wiping off the oxidation that was covering holes on the sensor

@mysticwine 7 лет назад

That won't do it.

@greyowl3472 6 лет назад

Disconnecting the battery will turn off the check engine light momentarily if not at all.

@ChumpusRex 11 лет назад

This is the 2nd O2 sensor which in almost all cars has very little authority over the fuel mixture; it is the 1st O2 sensor which most cars use to set the mixture; the 2nd reacts too slowly (because of the cat) to be optimal for fuel trim. However, in 1st O2 sensor malfunction conditions, many ECUs will give the 2nd O2 sensor some fuel trim authority, instead of dropping to open loop mode. In this fault condition, a false 2nd O2 sensor reading may cause engine damage due to incorrect trim.

@gutyourtrust 10 лет назад

Light's gone, must be fixed.

@moccina 10 лет назад

Nick Bazin Did you watch the entire vid ? CEL still off after 10k+ miles.

@gutyourtrust 10 лет назад

Yes.

@tomduncan1970 12 лет назад

Your a very smart gentleman..... funny how alot of the haters probably have never even seen a scan tool or 02 Sensor. Thanks for your intelligent response.

@copkhan007 10 лет назад

This modification may remove the check engine light but your vehicle will not pass the inspection because NOx is still coming through the exhaust pipe.

@tillman40 10 лет назад

that's where the gallon of methanol comes in LOL

@CoolStoryBro603 10 лет назад

Tariq Khan For states that do emissions testing via tailpipe. Many only rely on OBD readiness meters. Also, I know for a fact that Michigan and Florida don't have any safety inspection whatsoever.

@brianbritton6555 5 лет назад

I did this on my 05 scion TC worked and passed inspection . Did not pass before now it does

@WiNgZfinesse 5 лет назад

In ND we dont do that

@ronallen6196 5 лет назад

If you unhook the battery of course the check engine light is going to go off.

@hitmanLis 10 лет назад

Thanks man!!!

@moccina 11 лет назад

Pretty sad that someone actually took the time/effort to remove your cat and steal it. If they get caught it's probably the same punishment as if they were to steal the entire car lol-- not too smart. Anyway, the electrical tape cover up will only work until you actually need to get the car inspected / obd emission checked at which that point you will actually need to deal with the issue. Thx for watching / commenting!

@scottdiamond74 8 лет назад

The "maintenance required" light has nothing to do with any O2 sensor or catalyst on this car. This guy is wrong.

@jacobbpitt 8 лет назад

perhaps he misspoke. he meant the cel

@scottdiamond74 8 лет назад

Watch it again.

@FXproduction 8 лет назад

Actually I have an 01 buick regal and that unit does light up the maintenance required or service engine soon so it just depends on the make model and the ECU, ..

@scottdiamond74 8 лет назад

FX, what's your point?

@lostinmyspace4910 8 лет назад

His true aim was to get millions of hits, not truly troubleshoot the car default...he succeeded. Reader beware.

@moccina 11 лет назад

This is really not much work at all. Definitely never heard of one of those readers though, I'll have to g00gle it. Anyway, thx for watching.

@rosahodge420 10 лет назад

this is alot of work...i think I will ask mechanic to replace the sensor then go thru all of that.

@moccina 10 лет назад

Rosa Hodge Lol. It's not alot of work. Changing the cat is alot of work... say hello to frozen exhaust bolts, blow torches and bloody knuckles. This job is a breeze in comparison :)

@moccina 10 лет назад

Also, it's not guraranteed the sensor will fix the issue so be prepared for that.

@rosahodge420 10 лет назад

@mahnamahna1797 10 лет назад

@moccina 12 лет назад

You could try to defoul both secondary sensors but I can't say for sure because I'm not familiar with your setup. Try to find a forum that is specific to your vehicle and that will help a great deal. Good luck !

@moccina 11 лет назад

I think you got lucky. In your case the CEL took a while to come back and was in ready mode for inspection. Many times the CEL will come back immediately after it hits ready mode. Thx for your comment.

@bentback1 5 лет назад

Were your readings on the O2sensor "INC" or did it come back on after a drive cycle? If it reads "INC" at the inspection station it still will not pass.

@6uit4rist 12 лет назад

cool. i find this very helpful. how about the spark plug? any particular kind or brand?

@moccina 11 лет назад

I would need to google it. Never owned a Ford in my life. I'm sure you will find something if you search those words. Thx for watching!

I just tried this today after watching your video. 1/2 inch is too small for my 2001 Monte Carlo??

@moccina 12 лет назад

Yes, that is correct. The vehicle I did this on is Asian import (Acura/Honda). Thanks for watching !

@hotpinkslinglady5494 7 лет назад

if you have a 2008 xb. this works great. they also sell o2 sensor spacers...

@moccina 11 лет назад

I would laugh my ass off if one of them tried to cut a freshly parked converter. Those fuckers can get up to 500+ Fahrenheit yeesh!

@moccina 12 лет назад

It did not, since this was the secondary 02 sensor that I used the defouler on. I have driven the car approximately 20k miles -- Performance is on point and fuel mileage is excellent.*knocks on wood

@SuperTurboDiesel2 11 лет назад

It is NOT a filter. It is a spark plug non-fouler, which was originally designed for engines that have issues with high engine oil consumption due to high mileage wear, such as worn piston rings or bad valve seals & guides. It moves a spark plug further from the combustion chamber. The "kit" with 2 non-foulers is available at most auto parts stores. I bought mine from Advance Auto. You will need to make sure you get the correct threaded version for your application. 18mm thread is very common.
