P0420 code solved for under 25$ (Cataclean)

Link: amzn.to/3ZnKP6U (Amazon 1 pack)
amzn.to/3EFtWLJ (Amazon 2-pack)
Had a p0420 code for about 5k miles with no performance difference when code was showing. Someone I know suggested cataclean and it worked! I’m a couple hundred miles in and it hasn’t come back. I’ll be using a second run of it to clear out even more carbon. This only works if your cat hasn’t destroyed itself already.

[@otpyrcralphpierre1742]

One thing that most people are not really aware of...the Cat clogs up when your engine uses oil. Most people on here regularly change their oil, but most do NOT change their PCV valve. If this valve fails, your engine may well be sucking up oil into the intake. If you have to clean your Cat, change your PCV valve. It's Cheap, and it just might prevent it from doing it again.

[@pglover2010]

Thanks it worked on my 04 Benz Clk! I'd failed two emissions tests and tried Cataclean after watching you and other YTubers recommend it. I followed directions and drove around for about 20 miles then the codes suddenly changed to green without even having to refill the tank. I drove immediately to test center and passed!

[@mkecarconnection3808]

Fuck yeah congrats!!

[@1SuperD1]

Put half the bottle in the tank drove normally until the tank was empty. Filled the tank up and put the second half of the bottle in. This time I drove on the highway for 30 minutes did some shopping and drove another 30 minutes back home. Started driving the next day and the check engine light went off. I was told I needed a new catalytic converter but decided I’d try this instead and it definitely worked. I did not reset any codes the light went off on its own.

[@djdragons7734]

Did the light ever come back on?

[@1SuperD1]

@@djdragons7734 the light did come back on. It was off for a while then it came back on. Then for a while it only came back on while driving on the freeway. I still back this product 100%. My car is used and the last owner didn’t take good care of it. The dealership probably turned the light off manually before i bought it. I’m pretty sure if your light just came on and you’ve had the car for a long time it would work even better. At the end of the day these types of products are temporary solutions and they usually extend the life of your vehicle. At some point you’ll still have to go ahead and get the maintenance done along with these types of products

11-23. I own a 2015 chevy equinox LT with 2.4 engine. Replaced both O2 sensors,still had 420 code but no performance issues. Check engine light really frustrated me to point of having shop almost replacing cat converter.....while having new 02 sensors tested just incase, tech suggested cataclean or similar product. Purchased and followed directions that day no change,bummer. Next day on my normal route low and behold light went off,.!!! Week 2 and 460 mile later still good.

Worked on my 2013 Honda Insight. It cleared P0240 code on its own

[@DesignerBrandon]

Stuff works. I got a P0420 code and couldn’t pass emissions. Dealer wanted $4k to replace the catalytic converter. I got some CataClean for $26. After about 100 miles CEL disappeared. I passed emissions later that day.

[@nissianjeff2478]

The check engine light did not go off by itself on my car either. I had my friend clear to Code with his little handheld gadget he plugged in under the dash. And I spent about a week ago and I drive it every day and the light hasn’t come back on yet, so it seems to have done the trick and my 07 Cadillac CTS.

I got the check engine light with Po420 code but every time I drive 45min-1 hour on the highway the check engine light goes away for a day or two then come back on?

I put a bottle of this in my tank almost a week ago and then my friend shut off the engine light with his little machine thing he plugged it under the dash. And the light hasn’t come back on yet and it’s been about a week and I drive it every day. So yes, I believe it has worked for me also and if so, it was well worth the 32 bucks I paid for a bottle of this! A whole lot cheaper than replacing a catalytic converter on this Cadillac CTS. Let me tell you!!

What about a after market catalytic converter does it work for them i do feel something I drove it around 20 miles put gas in it but now the light is coming on solid and the other lights really don't even show that long but i feel something so do i need to clear the code or is something else wrong but its driving ok

[@mkecarconnection3808]

As of today, the light has been coming on and off for 35k miles but it still drives fine and has the same power and fuel economy so i don't mess with it since i got it to pass emissions. You can try an aftermarket one. If mine goes out, I am going to just take it out entirely. I moved to a city that doesn't need emissions now so im not worried anymore.

[@jeromemauricio82]

I think your just racist

[@ericmol2614]

I tried it but I'm going to put in another dose because so far it didn't work on my Prius. But I smell the exhaust and it's really bad and it may really need to burn out a lot of stuff because the battery was low too and I had to get a new one and that's when other trouble started. In other words as the new battery functions correctly it could have triggered fans and oxygen sensors that weren't functioning at an optimal level before and this could have sent gunk to the catalytic converter, that and the car ran out of gas and by trying to start it while on empty it could have pulled impurities to the exhaust, that's my guess, causing carbon sludge build up. My car basically needs a jennny Jones make over, or an exorcism. So I'm going to send more stuff in to clean the converter. I bought a new air filter as well and cleaned out the battery air cooling fan and ducts which also has to do with a prius getting better gas mileage.

[@mkecarconnection3808]

I hope it works!! Does your exhaust smell like rotten eggs? If it's gotten to that point your cats might be too far gone. How many miles? I had an 06 prius thag was totaled at 156k and replaced with a 2014 prius plug in

R U sUr Ur hyper style isn’t affecting your perception of specific directions for adding this stuff?🤔, like ‘drIvr like a psycho’ or watever you said?.. NEhU, the reason code reader didn’t change as quickly as your car is because it said ‘permanant’ as a code type, & if you don’t reset ECM or have a snazzy code reader that can reset codes, it takes like 50(in this case) or 100 miles to reset code on that. but NEwA, in addition to cleaning out all kinds of stuff in your engine, fuel system, etc., IF p420 comes back, it means that you probably DONT nEd a new cat., probley something before cat cause carbon build up, so IF that’s the case, the gizmo(as a diagnostic) STILL saved you like a grand$, or watever👋.
