P0420 & P0430 Easy Fix

Performed on 2010 Infiniti G37
The one I used no longer available on amazon
amzn.to/3SE71sr - spacer should work on both sides (but if not let me know)
amzn.to/3ty8J16 - socket for sensor removal
Size is m18 1.5

That is a very clean underside of a car under there!

[@PZPal]

Thanks, living in Florida keeps the underside very clean lol

this adapter never worked on a 2010 .6.1 dodge challenger with a po430 code. i actually took it off 4 different times and gradually increased the hole size in this adapter junk, the light in my instrument panel returned each time .. i know 100 percent my cat is the issue... this did nothing for me ty

HelloPZPal, I have an Infiniti JX 35 and my car didn't passed the smog test. Code reader showing PO 420- PO 430 efficiency below trash-hold ....I wonder if would be a same routine to fix my catalytic converter issue?Thank you

[@PZPal]

Sounds like it's the same issue. In my state there is no smog test requirements and I don't know if they check under the vehicle to see if there are adapters in place. Just check with your local laws and regulations, but if you can do that and it will pass the test, the procedure is very easy. Let me know how it goes if you'll end up doing it.

[@tiborzkarate1]

@@PZPal thank you ……..I live in Los Angeles CA we have very tough restrictions……. I let you know how it goes

[@stopher1971]

So was it the catalytic converter’s because the odds of both of them going out at once is not very good

[@PZPal]

I think it was catalytic converters

[@tdatilma]

Great video! Thanks for sharing. My 2003 Camry takes a lot of crankings to stay running. It runs for about 3 to 5 seconds, then stops. Eventually, it stays running. I have a P0420 . Could this be the reason it takes a lot to stay running? Does anyone know? I was thinking about replacing the sensors. Let me know. Thanks

[@PZPal]

My understanding is this sensor just tells amount of gasses post converter so I don’t think replacing the sensor will improve performance, but I could be wrong

[@tdatilma]

Understand, thanks

[@RexxorDDG]

I changed my down-stream sensors and it still is happening with brand new OEM cats. Could it be the upstream ones?

[@PZPal]

I doubt it if you get these check engine light codes. More than likely catalytic converters need to be replaced. Some countries/states can just install adapters (like in this video) to bypass the check engine lights, but check with your local codes/laws if its allowed.

[@RexxorDDG]

@@PZPal I just got brand new cats installed and this code still happening lmao. Only thing I haven't ever changed which could potentially cause this is fuel injectors or my upstream sensors.

[@PZPal]

@@RexxorDDG wow that's crazy. Keep me updated when you figure out what's the problem. It's always toughest to me to troubleshooting problems than to actually replacing what needs replacing lol

[@highquality85]

@@RexxorDDG what's the code you're getting?

[@williambutler4092]

I clicked on the link in your video to order the adapter and it’s currently not available on Amazon is there anywhere else I can get the part from

[@PZPal]

Amazon blocks those pretty fast. Probably just do google search and find them on other online stores

[@abuyaroub]

Hello mu brother My name souliman I have question for you please give an real answers I am leaving in UAE and l owner lexus ls 430 And lam facing the same issue I already purchased two sensors holder and the new model of this sensor are with samll catalyst and filters My questions Does using this type of filter actually cancel the operation of the sensor, and does the flow of gasoline stabilize? Please advise Many thanks

[@PZPal]

My understanding is since the sensors that I was testing with these adapters were post catalytic converter, it does not affect gasoline, but all it does is gets rid of check engine light. I believe the adapter creates bigger distance, so sensor still works, but shows voltage within the needed limit.

[@abuyaroub]

@@PZPal thanks alot bro

[@jeeppicker2986]

What bank is P0430?

[@PZPal]

Bank 2

[@firmetatt2268]

That’s not working for me only temporary the light back again

[@PZPal]

That's strange, I'd assume either problem with something else or the spacer is not long enough.

[@khaido2301]

Man these newer Infiniti are crap my brother has a 2014 qx60 hybrid with 2.5L and has P0420 code. I’ve seen a lot of them with these problems

[@boogerboy1111]

Hello I have a 2016 v6 mustang and both codes 420 and 430 are popping up I took it to my local Autozone and what popped up the catalytic converter before that my car was in the dealership for 2 months and they told my my cats are getting clogged what can I use to unclog them

[@PZPal]

I used this before amzn.to/46RKnQY and I heard people use it to pass emission tests. I don't think it will help in long run though, only option is to get those adapters (if your state allows it) or replace the catalytic converter.

[@chris-samuel-cesar]

Were can i buy the adapters at let me know??

[@PZPal]

You'll have to search on google as eBay and Amazon tend to block those products

[@LuisGomez-ty7xp]

where can I buy them 2009 dodge ram 1500 4 sensors

[@PZPal]

Search on Google as Amazon doesn’t sell them most of the time

[@HankGoodness]

Does this fix only turn off check engine light or will it make run better?

[@PZPal]

Just turn off check engine light.

[@chris-samuel-cesar]

Hi so if i have code P0430 i can put the adapters and the check engine light will dissappear let me know!!

[@PZPal]

It worked in my case

[@chris-samuel-cesar]

@@PZPal is it the same for 2010 infiniti m35 same adapters

[@chris-samuel-cesar]

@@PZPal and also do I have to buy 1 adapter straight and the other curved ..

[@PZPal]

No idea. I think size should be same as engines are almost identical. As far as straight and curved, you could try same as I did, but since its a different car, you could look there and see if there is same space as it is on my car

[@chris-samuel-cesar]

@@PZPal thanks

[@daniellizarraga4032]

The links don’t work for the adapters

[@PZPal]

It's tough to find them on amazon as in many states (or maybe even nationwide) they're not allowed to be used. You could find them through google search, just make sure you're not breaking any laws.

[@suncrusherofficial]

Hey brother, what should be the description to search on google?

[@PZPal]

I think oxygen sensor adapter will show you some results. Just check with your local laws on what you allowed to do etc.

[@nathang1332]

Which one is bank 1? P0420

[@PZPal]

From what I remember, bank 1 is passenger side.

[@djhinrg]

Them 2 codes gone then got new code saying o2 sensor overheated. . . . lol

[@PZPal]

wow that's crazy, can't even guess what it could be lol

[@mikaylaf.6099]

That’s b my breaking point😭 I’m sorry bud

[@strutynskyyroman1015]

Dosent work. Don't waist time and money And on the top of it it is illegal

[@PZPal]

As I said in the video, check with your local and federal laws before doing that. When I tested it, it worked flawlessly for over 20k miles.
