Second, we discovered something interesting. There are apparently more differences between the 93 SSE and SSEi.....My O2 sensor is a 1-wire.....with ground coming from the exhuast. Josh'* is a 3-wire. Is this the same as a 94 SSE? Allmachtige? Anyone? Need to know how many wires you have, and if this is an indication of a pre-heated unit. I don't understand why the Series I would differ between NA and SC on this part.
I looked in the 93 service manual for ya...
The supercharged engine has a one-wire oxygen sensor, while the N/A engine has a three-wire oxygen sensor. But you already knew that!
I think you are right about the sensor being heated, but I can only verify the wires by the manual. FYI, I changed my sensor last week and it had one wire.
