If its -40 or 120 then you need to replace the sensor. Make sure you check the wiring first.

Yep, your sensor is bad or your wiring is screwed up. Check the wiring. If that's bad fix it and check the readings. Becareful to use the same gauge/type/length of wire when repairing. Some types of temperature sensors are sensitive to this. If the wiring is good, buy a new sensor.
