I am getting the code for P0141, and i have checked the wires over and over again on the sensor. I have an o2 sim on this sensor due to the cat being not up to par. Any cheap fixes? i really do NOT want to replace my o2 sensor, any ideas would be greatly appreciated!!

 

I've heard that o2 sims don't work too well on our vehicles. Was the P0141 occuring before the sim? Also, is the sim an actual sim, or just a resistor you soldered in? If you were getting a threshold error with the old o2 sensor, you can do this: http://club3g.com/forum/showthread.p...nsor+catalytic

 

The code is new, and it is on a sensor that does not have an o2 sim on it. Bank 2 has the o2 sim, and it works great
