as usual a lot of good information. I really enjoyed the forst section describing how the cat works. it helps me understand why the post cat o2 sensor does what it does. my question is how do you check a cat with a wide band sensor that hardly moves on the screen. it's one thing I can't wrap my head around.
Hi Brandon, great video and, once again, saved it to my TH-cam diag folder. Two questions come to mind... 1- Do you have a rule of thumb to determine at which point the time difference is to short and you are confident to condemn the CAT? 2- Should I back this up with scope data? I ask because although I can see there is a time difference on scan tool graph data, I don't really see the time base so ti makes it hard to judge. Thanks again for all your do for the industry.
First of all,...Thank you! And great question. I wish I had a better answer for you, though. I typically view the data LIVE, so I get an idea of how much time has elapsed.
That’s a great question. I have never seen anything documented but I’ve seen older vehicles with a lag of 7 seconds and brand new cars with a lag of about 3 seconds. I have never seen less than 3 without pending DTCs (P0420 or P0430).
Nice Job Brandon! Question so your test running it lean, mean both 02 are fine working.. i just have a rear 02 going rich/lean, so their no need to replace it, just do that test run it rich an lean an if it responds its good ? i just have a bad Converter? Thank You
Retired ASE mechanic changing my 68 C10 pickup over to a 6.2, 6l80 trans system, I'm opting to stay with variable valve timing, maybe a very slight tune, but staying with cats and slightly concerned about taxing the cats with a tune change. Variable valve timing is a win/win for performance and emissions (450 HP stock or lower)!! Any thoughts on your end??
All bets are off unless the tuner can compensate. The difference between poor-performing CATs and a MIL is in the software. If the tuner tells the PCM to keep its eyes closed…no MIL
Dear friend. You think than the problem with catalic maybe in the software (computer)? I buy one but I need to find some technic than program it. Some technic said than there is the problem. Here in Puerto Rico is difficul find a good one. Thanks for your information.🙏

Hello friend. Hector from Puerto Rico. Good explication. I have a question about catalic. I have a camry 2004 3.3 with 115,000 miles . Have the code P0430. I do a tune up and add a catalic cleaner. The light ve on but later come off. Three days later come on but was the bank 1 sensor 1 and buy one original. Seven days later come on with the code P0430 again. The car run perfect, the only issue is the light. Some technic from here and outside tell me than the problem is the computer. In base of your experience, what you thick? Bad catalic ir Bad computer. I hope than bright me some explication m. Thanks a lot.🙏🙏
It's very difficult if not impossible to correctly diagnose your P0430 remotely. There's other checks you need to do before replacing the catalytic converter or the engine computer. Get a scan tool. Check your fuel trims, oxygen sensor operation and voltages. Run it rich by spraying brake cleaner into intake manifold and see how oxygen sensors and fuel trims respond. It might be a bad O2 sensor, O2 sensor wiring, or exhaust leak near the catalytic converter.
Ty sir for taking the time out and giving us a refresher!
It's my pleasure, Honestly

Great refresher by Brandon Spectacular
Thank you ver much!

my question is how do you check a cat with a wide band sensor that hardly moves on the screen. it's one thing I can't wrap my head around.
Abundance of knowledge thank u
It's our pleasure, thank you!
Never seen this method. Usually see 5 gas analyzer tail pipe testing. Thanks for another option. Also hope Pete is doing well
Pete is FANTASTIC, as always!
Excelente!👏👏👏
Thank you!

Makes sense... I guess it's one more case of "look at known good until it's familiar enough to spot when it wrong"
Thanks again.
Oh I thought this was a video of animals that say meow.
Meow is what you say when me have to pay for a expensive converter
NICE Job again!
Thank you!
Is there a rule of thumb on the lag time if you were to use a scope?
That’s a great question. I have never seen anything documented but I’ve seen older vehicles with a lag of 7 seconds and brand new cars with a lag of about 3 seconds.
I have never seen less than 3 without pending DTCs (P0420 or P0430).

Appreciate the video.
Amazing👍👍

I would really need to see some data to make a decision. I’m sorry
Sorry my friend. The second question was not for your. I thick than other persons coment and I can send a question. Sorry again.
My eyes are so used to graphing using an oscilloscope. I would have loved it's use here.
Great video thankyou for posting
