Thank you for your video! I scanned my '07 Avalon 3.5L and it was a P0420. I had already replaced the O2 sensor on bank 1 ahead of the converter, so I replaced the O2 sensor after the converter on bank 1. CEL went off and then came on later. I saw your video, went to the part store, bought the cleaner, and rented an O2 removal tool. I sprayed the cleaner in 5 times at 5-10 minute intervals and sprayed the O2 sensor. I cleared the previous code and started the engine, and after a couple of minutes, the CEL went out. Hopefully, it's fixed. Thanks again!!. A final thought. For people who try this, as you are spraying the cleaner into the O2 sensor hole, make sure that the little tube that pushes into the spray button does not fall into the hole. You would be in trouble!
This guy is good on keeping communications with people who have questions in the comments. Thanks. Keep the good work.
Thank u yup I tried to help as much as I can I do get comments that’s I can’t reply back some times it shows but when I click it dosent come up
I sprayed that throttle cleaner through the upstream O2 port and my p0420 check engine light turned off on its own. Thank you so much for this advice. You are great and you saved me at least 1,000 dollars in repairs.
Nice good job!!!
Just wondering if I have to remove the bottom sensor as well? I already popped off the top one and I have the throttle body cleaner but I don't want to spray it in there and have it catch fire. Do I have to remove the downstream one as well or only put it in the top and clear out the the honeycomb? I inspected it with a flashlight in the Combs look perfectly fine
@@krakenhits1587did you ever figure out if the down steam sensor needs removed too?
@@BRANDONGONE92 no
The answer to your question is said in the video, but it isnot shown. He said to make sure you do the bottom one.@krakenhits1587
Always disconnect the o2 sensor wire connector. If you don't you'll be buying another, the wires twist, stretch, or break resulting in o2 error codes.
was gonna say the same thing would have taken 20 sec
no its must be cleaned with cata this is wrong cleaneng...
Ohhhh man I wish u would have used the camara to see if their in immediate reaction.
True
You basically want anything that’s going to eat carbon diesel fuel, purple power, optimizer GM top in cleaner, the foam spray and you really want to use a whole can on it and just let it set that GM Pop in Cleaner if you spray the cylinder or a cat and let it sit overnight And then the following day get the cleaner out look at it with a borescope camera. He looks brand new in there the GM top in cleaner optimizer for Chryslers that is for carbon cleans. It breaks the carbon down into dust you could D carbon your motor with water it’s a old-school trick, I’m not going to explain it how it’s done or watt temperatures or anything of the sort because if you’ve never done it, you can destroy a motor it’s the old-school trick and the old guys out there know what I’m talking about they’ll know exactly carbon and water. Don’t get along with each other who loses the battle the carbon does, this is how they done it before we had all these chemicals all old-school tracks there’s still out there we still use them. They work on modern days now computerized a lot of times you still have to use them. There’s guys out there that knows the tricks and lotta guys don’t like to give their tricks up they don’t believe in letting their information out And I’m one of them because if somebody does something wrong I’m liable I could be sued because they’ve done it wrong. The way the world is now everybody wants to sue and there’s one say payday is what they say not on my clock. I’ve told a lot of these guys it put a UA-cam videos out. You got a watch it because you put that information out and somebody does it wrong you’re liable That’s why I don’t put a Videos out because there’s too many people out there that don’t use common sense no more that’s the number one reason they can’t think on her own and the new generation out there is coming in the automotive they think the scanner is the god that code is the problem. The thing is they need to learn how to read the scanner read the data That scanner disappoint you in a direction. Where are the problems that and then you got a figure it out you have to diagnose it because the scanner will tell you if it’s electrical problem mechanical problem, sensor problem or internal problem it’s all in the way it’s worded, you have to know how to read between the lines And have enough background in the automotive to figure it out or diagnose it and a lot of guys out there. Just want to throw parts at him all day long and just say check engine light used to thousand dollars worth of parts at it still not fixed it could be a loose pin. It could be a bad ground. It could be a broken wire, or it could be were a mouse chewed on the wires why do you have to get a meter out and start diagnosing it nowadays that is a bad word to people they don’t want to hear diagnose in a vehicle. They just want to throw parts at it and go people need to learn how to take a step back idle down take some time fix it, right Yeah there’s some vehicles were you have to have a part known good part for a test part for a quick test to determine OK which is it here? If you’re in a time frame you can throw that part on there OK spit out another code OK that wire is good but it’s not. It helps you that’s all I’m a say and then you just have to figure it out yourself. and people need to learn how to pronounce catalyst system not Cadillac.
After spending quite some dough with various mechanics trying to fix my vehicle I just followed your tutorial and VOILA! The dashboard lights are off!!! Many many thanks, Bro!
Nice great job!
this guys is a car saver thank you
Yup welcome!!
I hope people realize you can't clean the cat with mass air cleaner like come on bro do it the right way. And unplug the o2 sensor you just ruined his wires because your to lazy to unplug a wire that takes 20 seconds.
He didn't use mass air flow sensor cleaner he used throttle body cleaner he clearly showed you the label, there is a difference!
So I need you to make me a small video showing me where the o2 sensor is lol on a 2011 Nissan Sentra lol jk I will google it or U-Tube it too !! But THANK YOU SO VERY MUCH FOR THIS INFORMATION BECAUSE I DID NOT KNOW IT
😂😂😂
I have tried: drill a small hose in the exhaust before the cat con: and WHILE RUNNING spray (carb cleaner?) w plastic spray tube into the hole.... careful, will melt....... but goes directly to the cats, air flow. Seemed to improve!. And tap, screw in a screw to block the small hole (accessible for future treatments)
Good job!!
No concern for UT catching fire?!
Still no check engine light?
Update please.
Great job
Thank you. I did the same thing you're doing and it cleared the check engine light. Did smog check and it passed.
Nice good job
For how long did it worked?? Am trying to do the same thing to mine but I was wondering if the check engine light stay off
@@elmexicanodelabarba3245 give it a shot maybe it lasts longer than you think
America mechanic will charge 2000K for replacement 😁 awful service
Thank you RB. It worked for my RAV4. it took 2 to 3 days to disappear the P0402 code.
Nice good job
Alright then, definitely trying this on 97 pathfinder. Thanks for the input.
Good luck!
I got 2011 gmc terrain 2.4l it was stalling and losing power sometimes when going up hill I took it to Buick and GMC at highland Indiana they told me the mix is rich and they will change high pressure fuel pump and the repair would cost me $800 with part included. I told them I will do it another time not today. So I go home watch youtube videos on how to change the high pressure fuel pump ordered the part from rock auto for $200 bought tools from Walmart and Amazon did it myself I even changed the oil. After all that it was still stalling and losing power like usual. So I thought maybe it was spark plug so I changed them myself same problem then I changed both solenoids same problem.
Until came across a video about catalytic converter issues. So I watched your video too because I didn’t want take down the cat to clean it so remove the upstream 02 sensor went to Walmart bought some Lacquer thinner use a flex hose and funnel and pour Lacquer thinner in. Then I use mass sensor cleaner and clean o2 sensor too. After putting back everything in place I turn on the car it was smoking a lot then after about 10 mins the smoke clear and I took it for a drive around the block then up some hills everything work well no more stalling and losing power. Thank you for the idea to put the cleaner through the upstream o2 sensor slot. Bless you and all the other UA-camrs helping us out by sharing your knowledge. Thank you my brother.
Oh wow u did lottttt I think maybe cleaning the maf sensor did the fix!!!
Good video. I wondered if you could do this. I didn't know if the liquid would cause the honeycombs to melt together. Good job!
U have to let it dry for couple of hours

Gracias esta muy bien explicado esto me ayudara mucho
Thanks for the video
No problem!
thank you for your vidio... your a great help
Very easy..tq sir share information..nice 👍
Thank u

You can also use an additive that is designed to clean the catalytic converter and spray it on there, it is designed especially for catalytic converters to be sprayed via the intake Port but you can do it directly on a catalytic converter which is more efficient
Yup
I just added a coupler and will properly clean it this coming summer. That fixed the light. Even removing the oxygen sensor and my fingers were frozen!
What kind of coupler did you add and where? I'm having the same issue.
I have a 2007 Toyota Tacoma 2.7 liter. The catalytic converter is horizontal. I checked the graph on the diagnostic tool. The second O2 sensor was erratic. I removed the O2 sensors and cleaned them with the throttle body cleaner. I then sprayed through the #1 sensor hole. I emptied two cans and stuck a air hose in it and blew it out for a few minutes.Since the throttle body cleaner is highly flammable,I decided to stick the hose of a wet/dry vac in the tailpipe and let it run over an hour. I then installed the O2 sensors and started it up. The diagnostic tool shows the #2 O2 sensor is rock solid at 0.015 volts,regardless of the throttle position. I call that a win.If the P0420 comes back, I will post it but, I think this is cured.Some people are using laquer thinner in the tank.Don’t Do That It can damage a lot of parts from the fuel pump to the injectors.Bad advice as far as I am concerned.Thanks for the video.Each person will have to adapt your proceedure to their individual vehicle but,this works very,very well.
Good job!!!
Is the code came back?
@@marsinbako8491 most cars I do don’t and it dose improve fuel economy also clean out the oxygen sensors
@@marsinbako8491 Yes it did. I looked through the 0- sensor hole with a camera.Catalyst material is not broken or stopped up. I installed a extension on the # 0-2 sensor and reset the p-0420 alarm.Problem has not returned in 2 months.There is no emissions testing in my state.As long as they don’t, I am going to treat it like a low tire pressure alarm.Not interested

Very good idea, thanks
Welcome!!!

I have a 2009 nissan altima same problem. Will try that and report. Thanks so much
Yup use catalytic cleaner let it dry off for a bit also u can try fuel injection
@@RBTheMechanic Thanks so much
Do you mean to say that, "..you can use fuel injector CLEANER"?@@RBTheMechanic
OK, gracias compa. May have to try it!
Once you turn turn turn then the wire is snapped off cause you twisted the wire .
Yes just stick it in the hole and spray.
Great idea! I'll try this on my 2013 Hyundai which is burning one (1) quart of motor every 500 miles; and, now, the car has driveability problems.
Oh those are terrible!!! Try fixing ur oil consumption issue first
Check out piston soak videos.. B12 cleaner or others
Yes the hole gets hot. So spray and do it 4 times. Stick in the hole 4 times and spray
Are you referring to soft porn? 😂😂
I should have seen this video yesterday before I tried to fix my daughter's Audi A3... It had a bank 1 sensor 2 error, with engine light orange. I took out the sensor and cleaned it very well, then replaced it and deleted the error code. She drove the car approx 1 hour, and the engine light has not returned 🙂. Now I know what to do if I get the error again. Thanks for a great video!
Nice job!!!
Worked! Thank you
You're welcome!
Is the p0420 code still off?
@@ducrogers302 yup car passed inspection also
Vacuum on the exhaust pipe seems a good idea. Help to suck the fluid into the cat and dry it out before starting. Also a spray bottle with some distilled water as a rinse. Trying this on a 94 f150 today. Will report.
Cool yup let me know
report please, report. it's 6 days ago. What happened?
@@irisbaez1972 I’m sorry refresh my memory
@@RBTheMechanic John leigh says he will report back, still waiting but he never came back
@@irisbaez1972 oh yeah true lol I though u was waiting on somthing from my end
Looks like it's worth a try. Good information.
Yup
supposed to put never seize on sensor threads
I have a 13 Mitsubishi Lancer with a horizontal cat. I had a p0420 code come on about a year ago. I tried a bottle cataclean about 4 months ago and the code went away for a day and came right back. About 2 months ago I removed the front o2 sensor and sprayed about 2.5 cans of seaform top end cleaner into the cat. I made tons of smoke and it took about 10 to 15 minutes to burn off but did nothing. Well just today I bought 6 cans of Berryman carb/fuel system cleaner (90oz) and poured them into the cat via a flexible funnel (through front o2 hole again). Chased it with a tank of compressed air. Since it says the Berryman is highly flammable I then added about 1/2 to a gallon on purple power cleaner/degreaser to the cat and chased it with compressed air again. I didn't pay attention to the check engine light when I first started it up but when I did, probably about 30 seconds after startup, there was no check engine light on. Hopefully it lasts but the procedure I described worked for me immediately for a stubborn light that was on for about a year.
Did it come back?
@@originalimmigration Not yet but it was only yesterday and I have only driven 25 miles.
Came back?
@@Jerri001 No not yet! It has been at least 2K miles if not 3K. Still no engine light!
@@theMatrixEndsHere thanks
Skipped a little of steps and used the wrong cleaner. Sea Foam is what you need to use. Also use CRC contact cleaner to clean the contacts WHEN YOU DISCONNECT THE SENSOR WIRES.
Ok
Seafoam didn’t work for me.
@@lorikuck19 You're not supposed to ingest it.
@@MexicoAdventurer no shit. 🤦♂️
@@lorikuck19didn't work as a laxative either?😂😂
The first sensor is the precat sensor it monitors air fuel ratio. The second one is the one that monitors catalyst efficiency.
Yes
Thank you very much!
I applied this to my car today and it worked perfectly!!
Appreciate you!!
Merry Christmas🎉🎉
Good job!! Merry Christmas!!!
Have you waited for couple of hours ?
Heck yeah! nice video. What type of socket is that you are using to take the O2 sensor off?
Oxygen sensor socket 22mm or 3/8
7\8 special slit socket
Looks good as long as you don't blow that straw right into the hole😮
Yeah
wished you would of put a pressure gauge on to test before and after back pressure on that cat ,a good back pressure is 1 1/2 psi at 2500 rpm .
Yeah but that would make job hell of difficult pressure would go out valves
Throttle cleaner / solvents can flash off... also if cat isnt vertical I'd think the sediment would dislove but not fall off? Good idea though to remove the o2 and or drill a small hole.
I would like to see if the catalyst was damaged first. The throttle body cleaner is primarily xylene and would have no ill effect on the ceramic honeycomb. If the catalyst if fouled, this would be a temporary fix pending correcting the cause of the fouling.
This been good ever since. Passed inspection and all
Thanks will do this
Ok
I used to have a code for catalytic converter. I've been using injector cleaners in the tank every refill. No more engine light
Oh niceee
which injector cleaner?

@@nadeem5476 Israrted with cataclean twice it went away for 100 miles. But it came back for another round. I tried B12 chemtool same thing. I tried high octane more power but same issue. I tried Lucas, gumout, stp, and I can't remember what else. I found out that a regular stp or gumout used on every full tank will keep the code away for longer. Some how now I have to use it for ever. But like I said this is a 230k mile engine. I can't say what for newer
@@fernesal try using laquer thinner a gallon In half a take drive till the half tank is gone
Root cause : leaking valve cover gasket allows [integrated with spark plug tube seals] oil into the spark plug wells, causing misfire, thus damaging cat.
But there’s no misfire or oil in spark plug tubes

@@mkrp4 yup could be the issue good information to be away tho I see people drive around with heavy misfire and they lack to repair the issue then it gets more costly
You are correct. Quite often that is the case with DOHC engines.
@@RBTheMechanic
That’s what my reply is always. People saying coolant leak into cylinders BUT coolant level is the same & oil looks great
You can start with this method but if the catalytic converter has overheated on the inside it will melt the honeycomb and you'll have the code returning over and over usually after a few days or so sometimes a little more. Another thing you can try is when you get to a half a tank of gas full literally buy a gallon of lacquer thinner and pour it in the gas tank and then fill it the rest of the way to a full tank of gas and drive 150 Miles or more on the highway or use a tool to set your RPM at about 4,000 for 30 minutes and it will clean out the cat., Although the best way is to take the cat. off the car and soak the lacquer thinner through the entire catalytic converter from top to bottom and then use a soap solution( like some dish soap or liquid laundry detergent and water to clean that out afterward then spray out with hose and let it dry and then reinstall it. If you're just trying to pass smog most of those ones that claim it will clear the code like cataclean or CRC etc. will work to clear the code to pass smog but usually the check engine light will come back on later which is fine if you can get your smog certificate and register the car. I've done this and it works but again if it is melted on the inside it will only clear at temporarily and to do a long-term fix you would need to replace the cat any welder at a muffler place that does catalytic converters could tell you if it's melted buy inspecting it from the outside. As crazy as it may seem, if you Google it,it will literally come up with the voice confirming that it works stating verbally the paragraph with instructions of the lacquer thinner method. If your catalytic converter is not melted then I would recommend doing this every 3 months to keep it from ever needing to be replaced.
It worked well for me
Yeah If you want to fu*k up your engine insert lacquer thinner. How stupid do you have to be??
Remember people hold the can upward.
It shoots as much as it got in the barrel for the moment

Well I would reset and wait for the light to pop up and scan again immediately
I have a 2008 Mitsubishi Eclipse with the 2.4L 4 cyl. The catyletic converter is part of the exhaust manifold. I was wondering if this would work for my situation? I have also heard of using lacquer thinner. Could I use a funnel and pour a little in it as well as using the spray?

Why not unplug the O2 sensor instead of twisting the wire up?
If u becarefull u should be good but do so
That’s what I thought 😂
Wow I have 99 Toyota Camry manual transmission and the code came up as a catalytic converter, I didn't think to try the process of elimination and clean the O2 sensor but I will try this. Hopefully it will work.
What’s the issue with twisting the wires? You know that how manufacturers store the wire and how do you think it looks inside the wire loom? If you are worried about the wires breaking then it’s probably time to replace the sensor anyways
A lot of Toyota connectors become brittle over time. The huge pain in the ass of hunting another OEM connector down alone makes unplug as few things as possible.
Put high octane Costco, it has the most detergent, should work.
I have no codes but have a sulfur smell (more when accelerating) new battery and alternator (w/voltage regulator). Voltage tested and it’s good. 2 new upstream O2 sensors (didn’t change downstream under car). I think cat maybe clogged what do you recommend?
Yes it could be bad catalytic also down stream sensors
Be calm❤ You are a beauty
Thanks
If you put the spray can upside down you will spray co2 (propeller) instead of the liquid!
U have it ready then spray
I tried it yesterday after trying multiple options. Have a monitor hooked up to check data. On my way home from work all my monitors became ready. Passed smog.
Nice good job
Have you had any luck buying O2 sensors from auto parts stores or eBay? Not sure if I should buy OEM sensors or not or aftermarkets are acceptable?
Only from my trusted part store “ Buywise”
I've heard others say they add cleaner to it when car is hot, let it sit for an hour or so to heat soak, then run it to clean through. Is that safe way to do??
Yes u can do either or it’s fine
So for instance on a 97 Chevy 3500 dually I assume I would have to remove the O2 sensor right before the catalytic converter underneath the car correct?

Better tape your straw to the spray button unless you accidently drop it in the cat.
Yeah lol I done that with throttle into intake
I thought the same thing
Hi did it workout with that camry, coz i have the same issue with the same car camry 2005,i replaced 02 sensor but code P420 came back after a week
Yes I had free I had to clean or replace the downstream o2 sensor check that also
Its one thing to do what the customer wants. Okay.
But really, on that engine, it would be so easy to remove the cat assembly, leave it soak in detergent water over night, blow it out the next morning, resinstall, use an actual exhaust back pressure guage to confirm 0 pressure.
If, don't want to do all that, use a product called "Cataclean". Works good to clean out the cat, but won't fix a cat. Beware.
Bolt will brake !! I rather take out the sensor
My Honda Odyssey has two catalytic converters. I the check engine light come on and sometimes goes off by itself. I checked and it say bank 2 catalytic converter, the one immediately after the engine, similar to the place of your Toyota. If I put this spray in will the dirt move from Bank 2 to bank 1? Or will this clean them both?
I u can clean sensor but after u do this or replace sensor the down stream
Interesting. I wonder if this would be good preventive maintenance.
Font see why not🤷♂️
The EGR valve gets build up on it too. It can be cleaned as well. The intake manifold too. ( Dodge caravan 2.4) I'm referring to.clean the " tube" that goes to and from intake manifold too. On my van ( caravan) that " tube" was clogged up . I bought it from a one owner
So I got a 2005 Toyota Camry 2.4 l it's burning oil either from the valves or the pistons which I'm working on. Would it be crazy to use gunk cleaner and then spray it out as that helps to move the oil through or with the catalytics cleaner spray work just fine? This is my second cat because I failed to fix it oil burning issue. The new cat took a year before it started getting clogged

I have used seafoam
@ RB THE Mechanic, does the catalytic converter have to be cooled off, before spraying the cleaner?
And does the spray cleaner have to dry overnight?
Yes both would be good cold and let it rest over night or few hours
Also another question, do I use half the can or the full can of spray cleaner?

Mine was a 0420 and a 0303, 0304 (misfires in 3,4) ran cataclean, swapped fuel pumps, changed sensors, spark plugs, new coil, coil packs,,,,,,STILL THERE.
Just before swapping the cat I saw a UA-cam video that casually mentions, a stuck open PCV valve would foul the spark plugs with oil, the cat sensors would trigger, and the cat itself also would be damaged.
Swapped the pcv valve and the light went out, without reset @ 80 miles later.
I'm guessing the Cataclean worked.
Oh also check the coolant temp sensor because bad readings will mess up the air fuel calculation, making it run rich or lean messing up the cat, sensors, and possibly cause misfire and also hard starts in the morning.
Check vaccum leaks and injectors
You said 'you don't have to remove anything

Don't come at me for asking a dumb question..
But I have a 2009 Malibu 3.6. The o2 sensor and cat are accessible.

Drill hole? U don’t do that access through o2 port
I mean if you wanna cause yourself $100-$200 oxygen sensor go for it but I would suggest unplugging it before you twist the wires.

@@ahkh642 what kinda car u have not sure the set up of ur catalytic but it might not work out due to location on sensor
@@RBTheMechanic you probably have never heard of it , it's from a Chinese manufacturer called Gac Motor , Ga4 .
anyways thanks for your help i really appreciate the dedication you have for your channel you're a really nice guy i hope you get whatever you want in life you sure deserve it
hello friend, my 06 honda catalytic convertor is restricted. the sensor is on top of convertor. is this method working on mine too ? if yes, what kind of cleaner you offer? what about if using actual gas to clean inside it using pump or whatever. I've seen a video talking about adding to the gas tank. is that working same as directly clean the inside net through sensor hole? thanks for your help in advance.
If it severely restricted then u have to replace it
I have a 2015 jeep patriot and my engine check light came on and said my cat isn't working properly anymore and I feel it when I drive . now should I put the liquid in my gas pump to clean it before replacing it ?
No try cleaning g or replacing oxygen sensor first downstream
I thought there are two O2 sensors. One before and one after the catalytic converter. It is the one after the catalytic converter that gets fouled.
Yup. One before and after
Is this supposed to be done while the engine is on operating temperature or when it's cold? And is the engine turned on or off
Cold
Nice Video my friend, it really helps to people who doesn't have alot of bankroll to replace the cat.i have a 02 Toyota camry with 2.4 engine,i alreadyreplacedthe cat 1 year ago and the upstreams 02 sensor but i haven'tchangedthe downstream.Sir can i do this spray cleaner with cat cold or does it has to be hot?
Yes u can dosent matter hot or cold
92 cheby s10. 2.5l throttle body.. driving an I can push pedal an engine will go but u can feel it is wanting to keep up an slows down. let off gas pedal an it'll go again for a few....cat clogged? would this help my truck?
Do u have codes for catalytic. U can remove the oxygen sensor before the catalytic it will be loud but u can confirm it this way
Does this method work on all cars? I have a 06 dodge magnum I'm thinking of trying this on
Yeah just make sure u let it dry
@@RBTheMechanic thank you
Interesting that no anti-seize was reapplied.
No need
Antizseize should be applied
2 gallons of foaming carpet cleaner at 200psi until you see it come out the pipes
Ok
I did it Yesterday (04/21/24) and after that was white smoke coming out I hope it fixes it light off for now
Oh ok yeah smoke will go away
Are you cycling the car on and off between cleanings?
No just clean as much as can then let it dry for a while
Hi: my car oxygen sensor replaced, do the smoke inspection. now no fault code, does the car have to run for 200 mi before going to the smoke inspection?
It needs to be driver not all cars get ready in 200 miles some before some after usully cycle is 90 miles so try 90 miles then if u got scan tool to see if it’s ready or not other wise u have to take the chance
If the code reader shows catalytic bank 1 issue can the 02 sensor be bad despite the scanner saying the 02 is good?
Yes I had that case also when I replace catalytic for some cars code came back due to it really was fault of sensor giving false reading
