There's are 4 wires, 2 for heating, 1 for reading and what's the other one???
The simulator is just resistors really and I don't want to pay 65$ for resistors. If I lower the voltage from the sending wire, I can clear the code right? kinda like the first 02 sensor. It must work on a 0-1 or 0-5 Volts circuit so lowering the voltage will be like making the ecm think the cat is working or that I have a sensor.
Anyone know how it works and could explain me?

don't know if its different on your to to an eco but I know on an eco an 02 simulator is not just resistors, the computer needs to see varying voltage still or it throws a CEL, just a heads up
that's part of what I wanted to know

Are you trying to keep it form throwing a code?

yep. The car has a cat but when we changed the cat, I cut the wire of the O2 sensor because we couldn't find the plug in front. The wires are back together and it will throw a code. It was fine at first but during winter, the salt corode the connection and it ws throwing a code. My father redid the connection and it's still throwing a code.
Now a new sensor is 195$ CAD. The simulator is 75$ USD I think witch is pretty close to 90-95$CAD.
I could get a used sensor for less than that at a scrap yard but it can still fail. So I wanted to build one like I build my tach adapter. The tach adapter is around what 50-70$ ? and it only cost 5$ to build so it's a big rip off. The simulator is probably the same thing. Diode and resistance.
That's why I wanted to know how it was working.

well the 2 wiers are for the heaer, the 3ed is so the o2 has a ground, and th epurple wire is charged, an o2 works by gererating electrisety in milivolts, the computer reads this.. IE hoter= leaner with more heat comes more m-volts... Mitchell has a really good explation on how this works... this is really all i can rember.

I have one of those O2 sims (electrical one) that will only work right for about 3-4 weeks. I;m not using it anymore, I would be willing to get rid of it real cheap, if you want ot cut into it.
