Rep Power: 0 O2 simulator
I have a 97 EX 2 door with a test pipe and no secondary O2 sensor. I was wondering if there is a circuit you can build that will eliminate the sensor totally as it was rubbing against the bottom of the car with an extender. There are no performance implications I'm just tired of looking at the CEL.

Well I took the cat off because it threw a code because it wasn't properly cleaning the exhaust so a test pipe was a cheap alternative. The defouler worked but it was to long and would rub against the under cariage making an obnoxious squeaking sound. And you can't just let it hang because then the heater won't display the proper reading and you will get a faulty O2 sensor code. So I was wondering if there is a simple circuit I could build to simulate a working O2 sensor. But if nobody has plans for that, does anyone know what the resistance/current/voltage is for the four wires running from a working O2 sensor while the engine is running?

You need between 20 to 50 ohms of resistance to replace the sensor. I want to make a 'module' to replace mine. My cars MIL is on and has some other issues too. The module I want to make will plug in to the harness in the cabin. I saw an Accord owner(?) added the module to the harness by the center console. It looked fairly painless but I have a Civic.
