Want to remove/disable your rear O2 sensor without a CEL? Here's how..
I suggest running two 50ohm, 10 watt resistors from RadioShack in parallel to create a 25ohm resistor. The current is split between the two resistors to minimize how hot they'll get. Each resistor will have around 4 watts of power being dissipated through it, less than half of its maximum rating.
I had a resister on my heater circuit for about a year, it just recently burned out (I had it under the car). The place I bought it from doesn't sell O2 simulator stuff anymore because the EPA harassed them, but they told me to use a 40ohm-25watt resister from digikey.com, part number RHC-40-ND as a replacement.

I can't really get a good pic without taking my seat out, but there is a plug where the rear O2 sensor connects to the car wiring. On the O2 sensor side of that plug, there are two black wires. I have them connected to the resistor
This is from a post in the how-to section on installing an O2 sim:
The two black wires are Heater 12v and Heater ground. I cut off the O2 sensor since I don't use it at all
This is from a post in the how-to section on installing an O2 sim:
List of wires from the o2 Plug from the car on the o2 sensor side. Do not cut the wires on the car wiring harness side only on the 02 sensor side becuase it can be replaced very easily. The correct plug is BLACK.

this happened using 2 50 ohm 10 watt resistor in parallel. i noticed the cel comes on after driving a long time. if i just drive for a few min do not get the cel. i guess the resistor is heating up too much when driving for over an hour.

thanks.
Oh ok. well so i guess my resistor and your code is working. i now know y it is showing up. its because im using my zeitronix's narrowband simulator. I did this since i adjusted my switching point. i guess the wideband takes longer to warm up causing the slow response. does anyone know how to adjust the treshold for this slow response error?
