Changed:
Engine off, ambient sensor temp, I'm getting 2.5 volts out of Pin6 (0-5V output, 1V/233.3C).

Thus getting 580C instead of 20C.

Tested Pin7 DVM output (1V/100C) and getting 0.7 volts (and not 6 volts, roughly corresponding to Pin6 2.5 volts).

Engine off, ambient sensor temp (~20C)

* Tested Pin7 DVM output (1V/100C) and getting 0.7 volts

** corresponding to 70C

** not 6 volts, roughly corresponding to Pin6 2.5 volts.

* I'm getting 2.5 volts out of Pin6 (0-5V output, 1V/233.3C)

** Thus getting 580C instead of 20C.

Added:
Hint: The output is almost certainly connected to an input with pullup (possibly strong pullup).

* Diagnostic: disconnect anything from output, and measure DC voltage with DVM (the DVM has 1 to 10MOhm input impedance).

* Solution: make sure to connect pin6 output to an input without pullup resistor

Sensor connection (seems good):
