So, have you been running the resistor for 2 months with no codes or problems related to the secondary sensor?

right. No problems related to the seconday sensor.

My 10ohm resistor trick didnt work for me however nothing has so far. I've tried a tune up, the antifouler, and the 10M ohm resistor trick and nothing has cleared the P0420 code for more then a week. It's driving me nuts, I even have a cat on the car but I'm guessing something isnt working right and causes me to throw the code. Joon525 suggested checking and cleaning the EGR which is what I'll do next but I'm dying to find a way to get rid of the stupid code for good without going back to the OEM cat.

Damn 04! Have you tried swapping the sensor?

TPG: this is for your secondary O2 or primary? I will be running a Primary, but want to eliminate my secondary....as I dont care and wont have a cat, I just dont want the damn code.

who here has any knowledge or experience from the defcon O2 simulator?

Mine is the secondary sensor that I've done this with and is throwing the code.

madcatz · 10-12-2006, 01:21 AM

but is your O2 plugged in or hanging freely?

IIRC the origionator said he just let his hang/hung up out of the way

Mine is still installed as I have a secondary O2 hole in my cat, maybe I'll try this with the antifouler and see how that combo goes.

antifouler.....please do tell
