Thank you, sir. I feel kind of dumb now, since I thought that maybe it was the O2 sensor. I will try not to do this again without trying the "search" function first.

Another victim of 5-90s unceasing life mission of never using the same terminology the rest of the world uses if he can possibly find a more convoluted term for any simple object. :flame:
Nah - I've just read so damn many tech books that I'm starting to think in abbreviations and acronyms...
Perhaps I should put a list of common abbreviations and acronyms in my sig - but what fun would that be? :laugh3:
The rest of the world? I guess it depends on your source (like I said, I've read entirely too many technical books by now - considering there's a shelf full of FSM's right next to me, a shelf of parts catalogues above it, a shelf full of engineering books right next to it, and a shelf full of collected technical information below it. Kinda keeps one busy - if I don't talk the way they do, I'll forget how to read what they're saying!)
The RENIX HEGO sensors (Titania type) are variable resistance units, and are used in a voltage divider circuit to determine AFR.
Later/more common HEGO sensors (Zirconia type) are voltage-generating units, which react to exhaust gasses to create a reference voltage, which is then read by the PCM to determine AFR.
I'd not be surprised to find that the later HEGO sensors aren't similar to something else - something else close enough to be used in its place - but I haven't been able to look into that. The Titania sensors haven't been in use for a while in production - I'm surprised they're still priced as low as they are.
