Look at the chart....negative means as the temperature goes UP , the resistance value [ Ohms] of the sensor goes DOWN [ negative].
So , you measure the ohms and compare it to the gauge ..
I have a 38 ohm resistor in my tool box for checking these real easy..if you sub that resistor for the sensor, the gauge has to read 100C... just like the chart I posted says............simple.
