For future reference, I found out a lil while ago that every make and model vehicle has a specific step by step drive cycle that can be performed. Mine take 25 minutes. 2 cycles, 10 minutes each, driving in high gear, 2000-2500 rpm (55 mph for my car) with 2-one minute sets of idling in park in between each cycle. Nice vid
Yes that is true. For the most part, it’s hard to achieve that driving cycle . Not every road has 55mph straight drive for 10 mins without braking.
So a lot of shop just suggest to drive it as normal for 100 miles .
Thank you for your support 🙏
Hopefully this will help me with an off-road vehicle that’s has been giving me issues
To make it simple terms as long as your P 1000 code is gone. Your vehicle is ready to go through omissions when you have the code that basically tells you the system has been cleared. There is no data no misfire counters. Nothing is calibrated once that P 1000 is gone you can go in and look at all the monitors and see if they’re completed or not.
I got this to work by jamming fine copper wire in the ends. Codes cleared. Passed emission test.
That was the best step by steo clearexplanation from all the rest. Maybe you explain just like you have done in this video, how can I clear and fix the P0451 code on my 2010 Lincoln MKX please . I have ched and replaced every recomended sujestion and cant get rid of this code.
Thankx for that.
What have you done and replaced to fix the p0451 code you have on Lincoln car ?
thank for the tips , can i do same on my 2002 toyota tacoma?also if i'll just buy the one selling online do i have to get the regular one or the one L type.
Should work on any car . Just get the regular one. I have never use the L type
Hi thanks alot. Quick question I am getting P0430. I have to insert spacer in bank 2 after the catalatic converter right? I have Acura tl 2012. Help will be really appreciated. Also the bank 2 is under the hood in front of the car right
Yes.....PO420 is the code for a problem after the cat of bank 1......PO430 is the code for a problem after the cat of bank 2. Best to do both as the other good one will likely throw a code soon too....unless you don't mind doing it again later.
Great explanations! We appreciate the video!
Thank you for your support 🙏
This seems very helpful, do you know if the Dorman 42002 will work for a 2005 Honda Odyssey? Thanks in advance!
They are all almost exact size. And most of them you will still need to drill the hole a bit bigger.
So yes
yes i'm looking in to this because of a foul plug on my 2011 honda Odyssey wondering where I can get this cover cap
Hi , if you have a scanner to make it clear after the job then you don't have to unplug the battery wire before you work , right ?
Yes, that is correct
Just to known I have the code too! I have to do smog before March 24 I’m in California, those extensions are ilegal here right? Somebody knowledgeable Thanks !
Ok that's a special tool.
What about for a dodge charger ???
I done this on my 07 Toyota fj cruiser to try to get rid of the p0420 code no luck unless my 02 senor are bad it drives me nuts here in tecas 2025 emissions test going away i be happy
You have to drill the non fouler . If that didn’t work. Drill it all the way through or needs a deeper non fouler .
P0420 is the one near your firewall and after the catalytic converter .
If you have other codes other than p0420 and related to 02 sensor. You need to address that first
No other codes I do have a Magnuson supercharger with 24 pound fuel injectors gapped at .8mm with headers my pipes have turn dark in color mayb the gap too big I usually use my scanner just clear the code but it comes back it won't pass emissions but here in texas emissions going away in 2025 I might remove the cats and deep soak them to clean them but if they were clogged my vehicle would rub real rough but she runs very smooth I'm lost
@@jamesray3920 must be a nice ride.
Maybe you want want to put them back to stock just for inspection then switch it again
Would that work in California?
Hello men. Do I need to take off the spacer before I go to the smog station..
No
Will this work with newer cars? 2013 Range Rover sport. The catalytic monitor is not turning on.
Yes, if your only code is p0420 and/or p0430
@@autopurlieuI don’t have any codes but the catalytic monitor not turning on
@@harishbagha6310 what do mean by that? If you have no codes, why bother?
Are you due for emission inspection ?
@@autopurlieu yes I’m in California and already failed emissions due the catalytic monitor not turning on. It would be used to just get the catalytic monitor ready. I’ve driven the car over 500 miles already.
Nice video. My 2012 accord Passes all monitors but it has a pending code of p0420. Do you think it will pass a smog check in California?
It should pass as long as the pending codes doesn’t turn into active codes .
Just fix it , it that happens
czcams.com/video/4EfSfq1SB9g/video.html
@autopurlieu The smog tech told me that for cars after 2010, I wouldn't pass with that pending code. Nevertheless, I installed the fouler using your procedure with the same part number shown in the video. Hopefully it passes now. Thanks for your help !
@@ceezauto213 keep me updated
@autopurlieu I went into the smog shop with all of the smog monitors complete. But he failed my smog because he saw the spacer that I installed
@autopurlieu what state are you in ?
what if i use a pre drilled fouler will it still work??
As long as the O2 sensor fits in
Did this but forgot to unplug the battery wire. Have driven 56 miles with no luck. Suggestions? Thank you
After installing, you must reset the ecu to remove the check engine light. To do that, you can use a obd scanner to reset that or remove the negative battery cable from the battery for 10mins. The check engine light should be cleared and start driving it
@@autopurlieu thanks for the quick response! It actually turned off a few miles after the post and just passed emissions. Thank you so much you saved me so much $$ 🙌
@@GavinB211 I’m glad it worked 👌
So this will just stop the p0420 from popping up…until the catalytic converter eventually clogs up correct? It’s just a bandaid for the code. Wouldn’t straight piping it be more of a fix?
If you like a loud exhaust pipe . Also it will still throw a code when straight pipe. You still need to do this fix for your straight pipe
@@autopurlieu ok I’ll take your word for it. Thank you
@@98VdubGolf no problem . Just make sure you clear the codes after installing it . It works on every car
Your downstream o2 sensor monitors the efficiency of your catalytic converter.
@@autopurlieunot if you have the resonator it will still keep it quiet
How to know which sensor to do this to? And also is this permanent? I want to sell my car after I do this, I got p0420
This video will tell you which side is the p0420.
This is just a semi permanent fix. As long as you have this, less chances that the code to come back . To each car is different
Have you tried this for a mercedes benz ml350? Thx.
Should work .
It worked for like 50 miles, and then the light came back on. Should i try to extend it by using another one spark plug?
@@dreamer175 just reset it and the longer you leave it and drive it. The car adjust to it
@autopurlieu so every morning when i put the scanner in, it passes the c and then when i drive for 30mile, the p0420 code is pending, then when i drive 50 mile. The p420 is permanent. Are you sure the car will grt used to it? Thx for thr help buddy.
@@dreamer175 if it’s that often, yes, either space it some more or bigger hole
If you use that one that’s already made already drilled. It is not deep enough. You have to use anti-Fowlers and drill one I’ve use these ones that are already made and they’re not pulling the O2 sensor back far enough they don’t work.
Well looks like you didn’t even watch my video. Smdh 😂
I watch the video it’s in your hand do it correctly The premade crap is garbage you have to use an anti-Fowlers for spark plugs, and use both of them in a pack and drill one to a half inch and thread both of them, and if you do not do that it will not work the premade ones do not work at all
@@CharlesLease-ei1eeit's true, I've watched another video where a guy explains exactly what you are saying. When I find the video I'll attach it
@@CharlesLease-ei1ee please explain
@@CharlesLease-ei1eeright and on my truck there is not enough room for both it hits the frame
What do you use to scan the car
I have plenty of scanner but the most simplest and affordable is the Blue Driver
Notice: The original sensor has a crush washer to use against the exhaust bung. With the new piece added, there is no washer on the new piece that (also) fits against the same bung. Why would you say no washer is needed ? Seems you're risking a leak and if even a small leak exists it won't clear the code.
You can use the crush washer if you’d like to, I just never had problem not using them
@@autopurlieu ....your viewers should understand that the Dorman piece comes as 2 different part numbers, each with the proper M18 thread.... 42002 and 42009. The 42002 piece uses a TAPERED SEAT ( which assumes a mirror-image taper on the bung)....OR..it comes as 42009, with a crush washer and flat seat, meant to install on a bung with a flat surface....like we have here on most cars' exhaust for the sensor. People are simply lucky and taking a chance to "force" a tapered seat against a flat surface and hope to have it be leak free long term. There is a reason the original sensor has a flat seat with gasket....it matches the flat seat of the exhaust bung. Cheers.
what size of your drill bit
I don’t remember . I just measure the outside diameter of the O2 sensor
1/2 inch. You can step your way up to that diameter if you need to as well.
I am confused I have some cat looking things way down the exhaust pipe with a sensor
when you say way down the exhaust pipe? all the way back side close to rear wheels?
what size fouler what size mm?
I can’t remember but I believe I showed in and mention in this video if you watches it
m18
@adamb84
Hello, after I tried this, it throws the error P0154 no activity detected O2 sensor bank 2 sensor 1. Any suggestions?
You install this on the o2 sensor after the catalytic converter .
Bank 2 sensor 1 is the O2 before the catalytic converter
Yeah, I did that. And suddenly after driving it for about 10 miles P0154 appeared. After driving for an additional 50 miles, P0420 appeared again😢
@@danielecordaro6720 take care of that p0154 code first . Either broken wire on that o2 sensor bank 2 sensor 1 or it needs a new o2 sensor.
P0420 code , make sure that spark plug fouler has enough hole in it or sometimes you need to stack up some non fouler . They all comes in different height.
To each cars has different specs
@@autopurlieu I will replace that O2 sensor on bank 2 sensor 1 (front of car before the cat). I have the exact same car as your video so not sure what to do with that fouler. Drilled hole exactly like you showed…
@@danielecordaro6720 make sure the p0420 o2 sensor is back side , close to firewall cat and sensor after cat .
Sometimes it takes time for the computer get adjusted to it. Keep resetting / clearing the code. You will notice that the engine light comes back with longer miles driven. Or other option like what I said, stack up 2 non fouler in there instead of one.
That happen to me to other cars.
What obd scanner is that?
BlueDriver
Thanks 😎
Did your code ever come back after this
Never, until now I drive it without codes coming back
@@autopurlieu thank you
I did the same and it completely cleared the p0420 but now I get p0136
P1036 is your sensor bank 1 sensor 2 malfunction . Either you have bad wiring there or replace the whole sensor
I can tell you right now his engine light come back on because he’s doing it wrong. You have to use both of them if you use one it’s not enough you have to use both anti-Fowlers you have to drill the one and then thread the other one in there, too his light is going to come back on guaranteed he’s doing it in correct
All cars are different. for this particular car, I guarantee you light never came back on. Coz I daily drive this car .
If that happens, yes you are right. You have to stack 2 fowlers, which only happens to my 1 out of 10 cars .
👍🏽
Not always....it is dependent on the specific conditions of the car in question. Yes...many guys need both pieces stacked together to pull the sensor away a bit further....but NOT ALWAYS.
What type of car is this?
05 Honda pilot .
But will works on every cars
@@autopurlieu nice, trying this out on my 07' Camry 4 cylinder. Thanks 🤟
@@JPtruthvalueseek best of luck brother . I’m sure it will work
What bolt is that
What bolt? That’s an oxygen sensor ?
@@autopurlieu ok so you drilled like everyone else. Thought you did it differently not needing to drill. Show full work next time
@@omarrose4073 10:37 mark where I drilled it
Clearing the code will not fix tour drive cycle you will still need to drive 50 to 75 miles to make sure the code dose not return
I don’t think I mention “just clearing the code fix the problem “
You is doing it wrong you have to drill a bigger hole into that spark plug fouler for you can screw it on all the way if you look at your O2 sensor is not screwed in all the way
Well it’s been working great for me. The tip of the sensor never touch the bottom
@@autopurlieu I'm surprised you didn't get no check engine light that's good I just would've drill a bigger hole but good job...
@@Tootoojackson I used to drill a bigger hole. Now I just drill a bit bigger than the outside diameter of the O2 sensor. Been working fine for me.
👍🏽
I think the spark foulers are the ones supposed to drill. The one used in this video is special for O2
No...not correct (14:53 - 15:10)....a PO430 is NOT the front-side of the converter problem....it is still the backside problem of the catalytic converter ....BUT.... this time, on the "Other" side of a V-6 or V-8 bank of cylinders. Example..... for a V6.....bank 1 is that bank of 3 cylinders with cylinder "1". Bank 2 would be the other side 3 cylinders. One bank will throw PO420 code for *its* cat.....the other bank will throw PO430 for *its* cat. Both are downstream of their respective cats.
What I meant of front side (where you see me pointing my finger)
Catalytic converter near the radiator side (forward side / front side of the car engine) p0430
Catalytic converter near the firewall (backward side/ back side of the car engine) p0420
@@autopurlieu ...although you explain this correctly......viewers seeing "front-side" and "back-side" will more often relate this to front or backside of the cat...since there are front-side and back-side ( of cat) sensor locations. OK... I stand corrected, but it was confusing....cheers.
@@TheWilferch thank you for pointing that out.
You must watch the full video to understand and not just get parts of it . Putting text out of content
4:28 and 6:10 clips exactly explains the positions
You're really not "fixing" anything. Your catalytic converter is still bad regardless of manipulating the 02 sensor and tricking the ECM.
You are right.
This I meant for older car that doesn’t need to spend couple gran for catalytic converter problems. (As long as it’s not clogged )
However...a code gets tripped when the cat gets to be only 5% "bad" or degraded ( ie, operating at 95% of original capacity). Takes a long time before we encounter the totally-plugged condition you are worrying about.
@@TheWilferch I’m not worry of anything. Car will run with or without catalytic converter.
This all up to owners car if they want to do it or not. Most people don’t have the budget of spending close to $1k just to fix the $3k old car .
@@autopurlieu ....no argument there. Just reminding some responders that the code PO420/430 gets tripped when the cat is "only" 5% bad....it doesn't mean the cat is on its last legs. Cheers.
If your Honda engine light is off, engine performance is normal, and you can pass CA emissions then I'll say thank you and we'll done AP👍
