If the sensor is bad it will trigger a trouble code and the check engine light will come on. symptoms related to a bad coolant temperature sensor:
1) Truck uses more fuel than usual
2) Have trouble starting at normal operating temperature
3) Black smoke out the exhaust
Ohms test: Connect the black lead of the meter to the body of the sensor and the red to the terminal. You should have a reading of approximately 2000 ohms when its cold and a lower reading when warm.
