It is illegal in the United States to modify or remove factory installed emision controls on your vehicle.
With that in mind, people still look for ways around the high cost of replacing a catalytic converter. One of these ways is to use sparkplug non-foulers or de-foulers.
Since Project: Element has P0420, catalyst system efficency below threshold, I'm going to give this scheme yet another chance to prove itself as viable or internet rumor that isn't worth the time.
Keep in mind, even if these do work, nothing was fixed. You are just trying to trick your PCM. Not cool!

Why is it illegal if the fouler can be purchased from major retailer for that exact purpose?

@ktecgarage 4 месяца назад

Most folks disagreeing have been ugly about it, so I don't usually respond, but I'll explain. The defoulers are sold for sparkplugs, not your o2 sensors. You have to modify them for the o2 sensor. Even if your state does not require emission tests, federal law (that supercedes state law) makes it illegal to bypass factory emission equipment. 95% of folks that do this and get it to turn off the check engine light won't get caught. If I encourage people to do this, then youtube could pull the video. It would be irresponsible to encourage people to break the law. Several of the big youtube channels have been fined thousands of dollars by the feds for bypassing factory emissions. Do what you want with the information in this video.

It worked for me. 2002 Camry always throwing codes. Replaced the cat twice along with numerous other parts. I spent thousands trying to fix issues. Mechanics would “solve” the problems then a month or two later codes would be back. So I don’t feel bad about doing this. These rules hurt people who can least afford it the hardest.

@MarcBchannel Год назад

Worked on a 98 silverado for me. Its been a year still no cel👍I see a problem with your setup. You have to use 2 defoulers stacked on top of each other. One is drilled out so you can screw in the o2 and the one closest to the exhaust needs to be left unmodified with a small orfice on the end. This limits the exhaust gases that contact the sensor. Some defoulers ive seen have an assortment of different size orfices that you can tune with

Even if they seem minute. It's typically at the crappy flange between the cat and resonator/muffler.

Jeeps are terrible for tripping that code also. .

Because you didn’t do it correctly you have to use both of them one is not enough you have to drill the one and then throw the other one in there too. That’s why you did it incorrectly. I’ve watched quite videos, and seeing people do it incorrectly. You must use both.

It sucks to think I would need a new cat when for the last 5 years it has run smooth without issues and it gets great gas mileage. These invisible gasses are a money grab. In Texas they are fixing to do away with the safety inspection portion and just do the emissions. The safety portion is more important. I mean it was meant to check to make sure your brakes, horn, lights and windsheild wipers were working. That is more important than invisible gasses.

I'd be a lot more comfortable with this procedure if you guys on RU-vid would show the live data stream for the rear O² sensor before and after installation. As for the open end wrench you used to remove and install your O² sensor, I have a set of various O² sensor sockets. Sometimes they work, sometimes they round off the nut on the O² sensor. These days, I almost always use a pipe wrench to remove and install O² sensors. The pipe wrench grips better, doesn't slip, and round off the nut, and the longer handle gives me more leverage.

@MarcBchannel Год назад

I did this on a 98 silverado that it worked on. I didn't look at the live data before but after. It's supposed to be a somewhat flat line reading around half a volt +/-. That's what I read on the scan tool. It's been almost a year still no code. I think some cars have more stringent programming parameters that mite still trip codes tho. Also I don't know if having an intact or gutted cat makes a difference. Also some defoulers have different orfice hole sizes that can be played around with

It is UNREALIST to "expect" emissions to last more than 100k and to pay the repairs to fall within the emissions. Yes, many cars can do 20yrs and/or 200k, but the standards today are so high and the methods of achieving those standards require a lot. Most cars being manufactured today will end up in the salvage yard by 10yrs/100k because of these standards and the cost of the repairs to meet emissions in the future. It is just a SCAM to get people to buy a new vehicle. There is no reason to build such trash.......Vehicles should last at least 200k or 20 yrs. The amount of pollution that is produced by making a new vehicle is crazy.

@tksperformance8789 8 месяцев назад

I used some medium stuff between 00 and 1. Between the different OEMs there's no universal standard of what the ECU is programmed to look for as acceptable O2 sensor feedback parameters so a little trial and error is sometimes needed. A scan tool helps too so you can look at a graph of the voltage switch rate compared to the front O2 on the same bank. To much separation form the exhaust flow and it won't switch at all, then the ECU will purposely run very rich looking for a response and generally the car will run like crap. You want a nice lazy switching rate compared to the front O2 which switches pretty fast. If it's a fairly late model car it'll have wide band sensor in the front that will read the whole operating range of AFRs and not just stoich. You'd still want a lazy switch rate on the rear O2s, just nothing to compare it to. Hope that helps @@Wilhuff_T

You can do the same thing with the oxygen sensor itself. If it's a louvered sensor, take pliers and carefully close up the louvers. If it has holes, you need to make up some thing out of steel that will fit tightly around and seal it off. What you are doing is slowing down the exhaust flow into the oxygen sensor.

@alfredbernal8603 11 месяцев назад

think the best solution to pass the smog check is by the following procedure; BUT, if you have a bad cat problem initially preventing you from passing smog check, keep in mind people, your catalytic converter will eventually need to replaced to prevent damage to your engine. This is just a temporary method to try to help pass smog. 1) reset your codes using an obdII 2) remove o2 sensor#2 (Downstream), after cat and maybe clean it while you are at it. 3) install adapter 4) install o2 sensor unto the adapter 5) run your vehicle for 60 miles or more, depending on your vehicle so you can have all onboard monitors ready for smog check & hopefully yo check engine light does not appear. 6) the day/time of your smog check inpection, run your vehicle for at least 4 to 6 miles or more for a warm up. 7) remove o2 sensor (wear gloves & work smart as components will be hot) 8) remove adapter(wear gloves & work smart as components will be hot) as they may visually be inspecting undeneath. 9) re-install o2 sensor without adapter. ( wear gloves & work smart as components will be hot) 10) visit your local smog check station & hopefully it will pass without having the adapter during the test/inspection. Seems like a lot to do but it can be far better than replacing the catalytic converter just to pass smog. Tough times call for desperate measures! Good luck good people ✌🕶🔧

The problem here is price. If the feds mandate that we have to have it on our cars, then they should also pay when it needs to be replaced. Otherwise people will never stop looking for ways around the issue. EDIT: Also I think it's crazy that modifying it like this is illegal when driving around with a check engine light on isn't. Just leave the bad cat in there and enjoy the amber glow on your dashboard. Problem solved lol

Bad idea. The car is in closed loop mode and defaults to slightly rich running which gets poor mileage and can eventually clog the cats. Dont ever drive extended periods with a CEL on.

It is a bad idea. That car was getting 16mpg after the "hack." Thanks for commenting.

You have to use 2 per o2 sensor on rear bank,and your dead wrong,it most certainly does work without a doubt,do it the right way with 2 per cylinder and get back to us sir

It is an inline four cylinder engine, so it only has one bank. Did you mean bank one, sensor one?

@tattoo_stylez420 Год назад

@@ktecgarage you have to use two of them for it to work an it has to be used on the down stream o2 sensor . If u have 2 down stream o2 sensors then u will have to put two of those spacers on each down stream o2 sensor so u will need 4 defoulers. Although it does not work on ever single car but I can say it will work on lots of them. I have a 2006 bmw 330i and it work perfect.

@TheWilferch 10 месяцев назад

@@hajrudinkavazovic2231 ...you need to read the code more clearly....bank or bank 2 just tells you which "bank" of 3 cylinders ( on aV6) is involved....sensor 1 is upstream, sensor 2 is downstream after the cat. The process here is for downstream

Have to agree, this hack is pretty worthless, because it does not work, is illegal, and does not fix any problems. My solution to the p0420 code is to figure out WHY the cats, or 02 sensors failed. Unfortunately that is easier said than done. I have a 2003 corvette, with 250,000 miles on it. The OEM cats are discontinued, and the aftermarket cats are mostly cheaply made junk, not designed to last. The best I can find are the magnaflow OEM grade cats, that are only designed to last 5 years at best. The magnaflow cats cost $1500, and an x pipe costs another $500. Not going to spend over $2000.00 once per year to pass smog. I have some projects planned for removing possible causes of cat failure, such as replacing all rubber emissions lines, sensors, replace exhaust manifold gaskets, exhaust gaskets. In the meantime I plan on bolting in new cats and sensors, do drive cycles, and pass smog. Then bolt old cats back in, place new cats on shelf for next inspection. I then will be able to do all my projects at my leisure. Mechanics have a hard time figuring out the cat failure cause. Mechanics dont care that you may have to spend over $2000, on new cats if they are wrong in their diagnosis. Some mechanics that specialize in emissions wont even touch a car if OEM cats are not available. Some mechanics do just some basic tests, such as look for exhaust leaks. I suspect original cats failed because the exhaust gaskets were rusty, and in bad shape. I am learning a lot on things like fuel trims, scanner use. Apparently I have fuel trims at 23 percent, on bank 1. should be no more than 10 percent. Possible causes other than dirty cats and sensors, are vacuum or exhaust leaks. Other causes could be dirty maf sensor. Eventually I will get to the bottom of the cause, but in the mean time I will be beating the system and passing smog tests with my new cats. My way of beating the sytem is great, because no matter how sophisticated the smog testers become, I will always pass. These silly hacks such as messing with 02 sensors, using 02 sensor simulators, removing the light bulb, for the check engine light, and on and on do not work.

So many people disagree with my take in this video, so I'm glad to hear that someone else gets it. Just because emissions aren't checked in your state does not mean it's legal. It would be irresponsible to encourage folks to break the law. It's a shame you are stuck with this issue. I did a video where I put Dorman cats on a 07 Ridgeline and it's still passing inspection after 3 years. I know not using OEM is asking for trouble, but sometimes you have to do what you have to.

@wildlesbians 9 месяцев назад

I did use a magnaflow, it lasted the 5 years it was designed to. Last year it failed, and I went for the cheapo AP eastern for 500 dollars. The thing was so cheaply made, I had to have a muffler shop cut and fabricate the pipes, for $400, and they still could not get it to fit correctly. Those cats lasted 1 month. Also wasted a bunch of cash on repair shops to figure out the cause. They cant, or wont. @@ktecgarage

@ktecgarage 22 дня назад

Your comment sounds vaginal. Care to explain what's wrong? Should I have used two defoulers? If that didn't work should i have used 5? What? Explaining what's wrong would be manly. I'm all ears. I clearly say in the video that if it turns your light off that it didn't fix anything. You are just tricking the computer. The correct fix is replacing the catalytic converter. Not this BS.

Don’t waste your money I done it I drill. The one went through the whole deal looked at the data. Make sure everything was working correctly. No misfires thermostat everything exactly 10 to 12,000 miles. The exact code is going to come back you’re gonna have to deal with the issue fix the problem the right way, save your eight dollars either pull it off clean the carbon out or replace it. This is just to give you borrowed time so you get past omissions you don’t have to see the light for a while but it’s going to come back it’s not a guarantee fix I know I’ve done it people need to wasting your time you’ll find out for yourself.
