Yeah I got the P0420, catalyist effeciancy. Ereased it, came back 2 days later. I have the performance curve hgh flow cat. Was going good for a year and a half, but oh well.
What do you guys do to stop this? Does the spark plug non-fouler's trick work? What size/thread pitch do we use?
What about a sensor "fooler"? Or maybe cut the wires and solder in some resistors? But it's a heated o2, so, i'm not sure how well this would work. Not sure how smart our PCM's are. Like if it's heating up but reading the same voltage through heat up and cool dowm, is our pcm smart enough to say hey, this sensor isn't working right and through another CEL?
So what'd you guys do?
Ooh is this a subject I'm not supposed to ask about? If so my bad.
Easiest way to take care of that is hptuners. You can also use the spark plug antifoulers to remove the o2 from the exhaust stream.

Save your money. It might be worth something someday.
Yeah I was asking about that trick too. Like I said I knew of 3 possibilites, the Simulator, the resistor (not a great idea) and the antifoulers, which I think I'll be doing.
Do our o2 sensors use the 18mm size? Does anyone know off hand?
Also, I'm not starring at that damn light until I get HP Tuners. We're talking 6+ months from now before I get this turbo on. But I was aware that that is the easiest way.
I could be wrong but I think that the simulator is just a fancy resistor.
hptuners and you're done... just turn the code off...

The 18mm antifoulers should do the trick. Those are the ones I used before I got hptuners.

Thanks bud I appreciate the help.
Mystic I know hptuners is the best. Like I said I know that's thbe easiest way. I just need something for now.
Zz z I wasn't sure if that simulator would have a set resistance value for both the heater circuit and the signal voltage or even how all that worked. Which is why I made this post in the first place.
A sensor simulator is a voltage generator, not a resistor. It sends a varying voltage to the PCM, simulating what a sensor would do. Our cars run a test while they're running, that increases or reduces fuel a little. It anticipates the voltage change during the test. If the voltage expected is the voltage measured, we're good. Most of the time the simulator works, but sometimes it misses during the test and throws the light. I've run a simulator for a while and only have to reset my light every 4-6 months.
Voltage generator, that would make sense since my dumb ass forgot, yeah it plugs into the vehicle harness, not the sensor itself. Retard moment? Too much on my mind I guess.
I did the spark plug antifoulers method. Just in case someone searches the 18mm size worked perfectly. Definitely recommend drilling them out with a drill press. I highly doubt I would have been able to do it by hand without taking out a finger, hand, or pulling my hair out.
^^It worked and is keeping the code off??
^^ So far yeah, its working fine. I'll update again once some more time has passed, but thus far, today I was driving in perfect conditions for the catalyst monitor to run and no CEL.
well man, the the anti-foulers are only like $8. It's worth a try either way, ya know?
Still nothing today too.
Drill wut out
*****BLAME IT ON THE ALCOHOL*****
You drill one of the anti-foulers so that the o2 sensor and fit through it.
Oh ok so i need 2

Thanks fir the pig
