O2 Sensor Simulator SOLUTION!!!!
 

I had searched the archives and came up with no real solution, I even posted asking if anyone had come up with one, the reply was a simple no. So, here is what I did:

Bought 2 PSO2SIM's and 2 O2 Sensor Heater Simulating Resistors from <a href="http://mysite.verizon.net/vze7erz1/index.html">Baker Electronics</a> for a total of something like $90.

**BEGIN EDIT** --01/21/06

Just to be clear, the O2 sims + heater sims can be hooked up anywhere along the path of their wires, to help people with this I included both side(ECU/SENSOR) wire colors below. You can truly make a sleeper system by connecting the sims right off the ECU wires, and just removing/disconnecting the rear O2 sensor completely. The O2 sims are water tight and are small enough to fit into most places. The heater sims will need some space to breath, but are also quite small. I will post some pics as soon as I can of my setup.

I won't be making/selling these, sorry all! I will answer questions from those who have them, please post and/or mail me if that doesn't get to me.

**END EDIT**

The install took a lot of time figuring out wire colors, where to cut/soldier, where to place the sims/resistors..etc.. But in the end, it all works great! Here are the wire specs for those who are interested in doing this them selves:

Plugs are layed out the following way:

not bad, not bad at all. good work

If it works longterm, that's awesome. How long have you tested it ?

Paging Zoldman, mass produce these for the lazy :)

well done, gonna order me a set [edit] also his url is busted

2nd

Been about a week sofar
 

All tests(Heater/O2) have been run and have tested good. Previous to this install, my check engine light was on for about a month, heater resistance was found bad for passenger rear O2. I could clear the code, but it would come back the same day. Now, it seems all is well. I wanted to wait a week before I posted my findings...

Heres the link for the heater resistor for those who
 

don't want to hunt for it <a href="http://mysite.verizon.net/vze7erz1/id10.html">hiding in the Accessory Products location</a>

3rd!

I'll get it to him =-)
