does anyone know how to put together a bypass for one of the oxygen sensors on the exhaust system. my check engine light is on and diagnostics are showing a problem with one of the sensors or a catalytic. what i know about it is that the bottom sensor on the catalytic could be bypassed by putting together a simple device out of resistors. doest anyone know exactly how to do this?

 

www.o2simulator.com and if you cut all 4 of the wires, you'll need the Heater Wire resistor as well. I have both on my exhaust system and they cured teh check engine light. They come with instructions, its pretty easy, just need to find out which color code is the one for your o2 sensor.

 

thank you
