Do you think there would be a problem in using used O2 sensors out of a written off or crashed vehicle?
I need 4 for my 96' Disco. Anybody got any? (I am aware that I can buy them from Nathan Crabtree for cheap)

You really only need the front two. The rear two only trigger the CEL when the cat has failed. I will look for the link on how to trick the ECU into thinking it has good rear sensors. The bypass is just a few resistors and under $5.00

So it's only 200.00 for NEW sensors that will last +80k miles or the gamble on used ones that may only last a week or a few months.

I would be most interested in that link.
Thanks

Robert,

the voltage of the rear sensors needs to fluctuate or the ecu will throw a code for that too. if the volts stay the same it will see a "frozen" sensor and bam on comes the MIL. in my opinion buy new sensors from nathan or do that splice/solder job off of the nissan sensors.
