i have a 99 cali spec maxima with fed manifold and fed y-pipe and these codes with o2 sim remain. one guy suggested heater resistor wont work. driling bung holes i don't want to do .
Please... How do I get rid of these codes I can't pass inspection been driving with a bogus sticker for over a month now.
i Know this has been covered in other posts, What WILL WORK?
I have read through posts on this and with someone(guy is knowledegable) telling me that heat resistor won't work i don't know what to do .

I have an o2 sim, fed spec headers and y-pipe.

Are you sure your sim is working/plugged in correctly? I have none of these codes. Did you get a dual output sim? Or a single?

ok so my sim o2 went bad and i had it connected for less than a year. had white to one sensor and the other black,red and white to another sensor.
Ilya so you're saying if i connect a good sensor the same way it should resolve my issue?

and yea dual output is what i had purchased from 02sim.com

my p0141 code wont go off... cleared codes and everything and just replaced sensor 1 bank 2.... what should i do next?

According to FSM, P0141 is rear O2 sensor (Cal spec Bank1 Sensor 2; Fed spec just Sensor 2) behind the cat. If you replaced sensor 1 bank 2, you replaced front sensor on forward cylinder bank.

yea so replaced all sensors. nothing anyone know of a good diagnose mechanic who will ook at this issue. i think because of this issues when i drive hard my card ona turn would sometimes just die, scary feeling when driven with one hand. it's automatic 99 converted from cali to fed spec
