Fooling your 02 sensor
I thought I might have read it somewhere in this forum but I cant seem to find it. Has anyone out there ever fooled an 02 sensor with a resistor or something similar.
I have successfully done the trick with the EGR valve sensor so I think that it must be doable to the 02's as well.
Just wondering if it can be done thanks ahead for your input.

If you run a 2 wire sensor instead of the 4 you can put a resistor on the heater lines and this will get your light out. Other then that you can't because the sensor generates a voltage. You can rig up a pot and give it 0-1volt range.

Yes, if you're talking about a rear O2 sensor.
Here's what I'm using:

I have a friend that built his own using these instructions for a guide:

Both are working on trucks with a 3.4 swap.

Thanks again Mt Goat.
I may try the "build your own" technique as I keep having a code pop up for the rear O2 sensor. I think it's due to my high flow cat or possibly using the wrong sensor (from a '90).
Either way... would be nice to see the light go away.
