The sensors are just thermistors! They dont really out put a voltage! The resistance just varies up and down.

In my ST205 there are 2 sensors! 1 is in the intake manifold and the other is in the air box. I just did a quick test and got this results:
27degrees = 1.8kohms
18degrees = about 2.2kohms

I'm not sure how accurate those temps are I was just using a cheap thermometer beside the sensor!
