Catalyst converter still looks good, before to spend money to get a new converter, I would soak the catalyst converter in lacquer thinner, then clean it out. It worked for me the last two times. carbon built up is mostly the reason why setting this code, clean it up it may work again.

Great video! I have had people bring their vehicle to me because when their "check engine" light came on, they brought it to someone who claims to be a mechanic but i call them a bonafide "parts changer." They use their magical scan tool that says "P0420" and immediately tell the customer that they need a new cat. Then a few days later, that damn yellow light reappears, so they come to me or another mechanic. 90% of the time (after the cat has been changed), I use my smoke machine (but I like your method with the shop vac also) and I find an exhaust leak pre O2 sensor and repair it for a fraction of the price they paid for a new cat that was just a waste of money. These so-called mechanics should be made to give their customers a full refund because too many are ripping hard working people off and giving the good mechanics a bad reputation. I love to see good videos like yours that show scan tools are just to give you a good starting place to look for the problem and they aren't a "super tool" that tells you exactly what part is failing 100% of the time. Again, thanks for a truly educational video. Well done.

thanks to people like you . i had a mechanic charge me 700 dollars for a 03 Lexus IS300 MAF . Had nothing to do with the code i even took it in for. (my fault for not trusting my research telling me it is the APPS/TPS) . They gave my car back with the same TPS codes on there and siliconed my Throttle body connectors together so when i had it replaced for 1/3 of the price by a home mechanic-- he had to break the connectors and tape them back. I successfully sued in a small claims court. Thanks to this video i might save 1400 dollars as well.

Hi, i bought a premium exhaust and had local mechanic fit it, he did mention that the gasket provided with exhaust didnt fit correctly so he went and got another gasket, i cant help thinking the other gasket is the problem have problem now, i driven for about 3 weeks after fitted now car struggles on acceleration and and engine light came on, so i put my own reader on it, and im getting code p0420 and p0303, i wonder if code p0303 is triggered by p0420??? It just seems odd how the car was fine until i had the exhaust change, i also bought a 02 sensor but dont wanna change it if thats not the problem. I dont have a hoover that blows air how would i do the smoke 1? Thanks

Although there's no physical damage to the CAT and its not clogged, over time the rare earth metals in the CAT will be depleted to the point that the necessary chemical reactions to remove the toxic gases from the exhaust no longer take place. So it basically just wears out. And great tip on using shop vac to find exhaust leaks!

Thank you so much for this video. Clearing my P0420 error code in Camry 2005 with 184K miles. I followed by blowing air in the rear muffler so it pushed all "restriction" on the catalytic converter. First you need to add CATACLEAN in your gas tank (follow direction, drive it per direction). Then I removed the upstream oxygen sensor, then adding blowing air in the rear muffler for 15 min with Shop Vac Exhaust trick. You need to close the opening on the oxygen sensor for 2 seconds, then open it so the air pressure will "push" the restriction. Do it as often you like during 10-15 min. Then install the oxygen sensor back. It make my check engine light disappear (error code P420), and passed NJ inspection for my Camry 2005 with 184K miles. Thank you, save my original catalytic converter, save money, as of now I already drove 150 miles without the check engine light.

From what I have read and viewed else where, use a scanner to monitor the live data for both of the O2 sensors. When the car is still cold, the output O2 sensor will mimic the input O2 sensor. Once car reaches the operating temp, the converter starts to do its job, and the output sensor will go to the steady line. You can also use a laser temperature gun to measure temp at both in and out pipes of the cat when at operating temp. If cat is working, i.e., burning the residual fuels, the output will be hotter than its input by quite a bit.

Amazing......I have a Scion xA, ...288,000 trouble free miles....and it's throwing a P0420 code. I hear an "exhaust-leak" that sounds incredibly like your car here....a "far-away-jet-engine" noise that rises and falls with throttle position. I found no other vid like this...and the sound you captured , like mine. I had the exhaust "doughnut" replaced at the exhaust manifold where it meets the exhaust pipe....using the spendy Toyota gasket...and the jet noise is still there....and so is the P0420. I used the Scotty Kilmer trick of adding the 1:9 ratio of lacquer thinner to gas, and the code is still there. car runs great both before and after doing this. I also replaced the downstream sensor with a new, OEM style, NTK/NGK brand...as I was getting PO138 before and now it's gone with the new downstream sensor. PO420 is still there and I fear I'm in for a new cat. Will review this vid with interest !!!!!!! ....... fingers crossed.

I got that curveball dealing with an 06 E350 Benz that had a faulty secondary air pump. Now I’m dealing with a 2013 Ford Flex throwing a P0420 & P0430. Took the front cat off and just like your video the honeycombs looked clean & intact. No rattling either. 175K miles. I don’t believe this car has a secondary air injection so should I assume the cats are shot? Unfortunately my scanner is down, updating messed something up. What’s strange is I also noticed an almost 1.5” air gap between the rear cat and downpipe flange while I was down there. I was going to assume that possible leak might’ve caused the problem, as I did remember a slight vibration at higher freeway speeds (though it’s an assumed correlation), BUT according to your video, since it’s technically “post-cat” that it might not be the reason for the codes!? Or am I mistaken? Any help would be tremendous.

WOW, 330k!!! Sweet! Sadly it looks like there's nothing built today that will make that distance anymore without major engine work (timing chains, mostly it seems). If there is, it will be Toyota, for sure. That's a great exhaust leak finder - great idea! 😎 I've used my cheap paint-can smoker on exhausts several times. It does work, but it's harder to see where the smoke is coming from. Much easier to see bubbles. I just did a '06 Corolla cat, 137,6xx miles - the top of the cat had blown right out from rust. The rest of the system wasn't a whole lot better, either. Replaced everything from the cat back. A little different design on this one - I didn't have to touch the header. The cat was bolted to the header underneath. I also got both the flange nuts off after getting them cherry red, but the studs were destroyed. Had to feed a bolt in from the top, while balancing the assembly on a lift jack stand, and attempting to tighten with my left hand. The classic reach-around, lol. After a few choice words were shouted, I got it tight and leak free. 😁

I think across the United States there is a high demand for well used but still functioning automobiles. With greater income disparity lots of folks with lower paying jobs need any form of transportation that is somewhat reliable and will get them to and from a job and is in the $1000 -$3000 price range. That would mean a vehicle with 200,000+ miles and is 10 or more years old. Any car driven in the northern "rust belt" that fits that criteria will look like "Swiss cheese" (pun intended). But there are lots of these cars in the southern states and California where road salt induced rust is NOT an issue. You cannot get much trade-in value in their local domains but used car dealers can afford to pay a little to a southern state dealer for the vehicle and ship it north, sell it and make some profit.

Great video and presentation. Is oil-burning ever a cause for a solo P0420, (ie a bad valve-cover gasket w/ oil leaking into chambers thru plug hole?) I have this same engine (2AZ-FE) on an '09 2.4 Camry [w/ 440k miles]. I recently replaced the upstream & downstream cat (upstream-cat was cracked & downstream-cat was clogged). The new cats greatly fixed/improved previous performance issues. It passed emissions test despite having the p0420 code..

I thought the post o2 sensor had to oscillate. My 05 corolla had a bad cat and I just rodded it out and installed an o2 simulator. when I hook up my scanner, it cycles from .95 to 0. It holds for about a second at the .95 before it drops off. With the bad cat it was acting like yours did. I also had a 09 corolla and it would go to 1.1, hold for a brief second the fall. I do like the shop vac trick. Thanks for all you do Mike!

Hey Arthur, yeh a smoke machine would do the trick. I think it takes longer though, the shop vac has a lot more volume :) Mike Becker, Senior Instructor
