3 wire oxigen sensors

I have one wire oxigen sensors after each long tube header, wired to their own guage in the dash. They take a long time to warm up and cool down very fast. I've read somewhere that they have to be 600* to operate correctly. I'd like to switch to the 3 wire, heated O2 sensors.

Lets assume I buy some 3 wire O2 sensors. I assume the three wires are: guage, ground, and heat. Is this a correct assumption? If so, does the heat wire only require a "hot when on" connection? Does the heat wire need to be regulated in any fashon?

Thanks for any info.

Sounds like you got it all figured out.


Heater just takes straight 12 volts it doesnt need to be current limited or anything like that. Hot and a ground for the heater element, usually two white wires doesnt matter which is which.

One wire for the sensor. Sensor ground is through the casing & through exhaust manifold.



There are 4 wire sensors from newer vehicles that have a wire for the sensor ground. They cost more though.

Do most O2 sensors have the same thread pattern and bung diameter?

Yes. All that I have seen are M18 x 1.5 metric threads. Even the newer wideband sensors.
