Well...

As it turns out, our little fuel gauge, while it can report
temperatures, OT, UT (over/under), and so on, the temperature parts
are not hooked up. I haven't read the data sheet that closely, but my
guess is that's temperature from a known reference voltage, usually
converted to/from a DAC somewhere.

Anyhow, thank you those who responded or are following this for the
clarification.

Regards,

Michael Powell
