UEGO Five wire Oxygen O2 sensor
Anyone know the difference between a UEGO 5 wire and a typical 3 or 4 wire O2 sensor?
Wondering if there are enough advantages, and if I can even replace a 3 or 4 wire O2 sensor with a 5 wire sensor?
I know where the wires connect on a 4 wire, how are the five wires connected?

Re: UEGO Five wire Oxygen O2 sensor (dsagers)
An EGO is a basic O2 sensor found in most modern cars; UEGO is a two-cell Wide Band (WB) system.
Their applications are very different, and the two are not interchangable without a lot of rework on the average GM ECM program, and/or some electronic fabrication.
Basic info on EGO can be found here:

Look in section 3.

Info on a WB design is here:

There are more articles around but I don't have the references handy right now. You can also use the "Search" button and look in this section of the Forum.
