If the wiring and connections are good, the TW sensor itself could be bad. They do have a tendency to go 'open' at times. FYI, they are just variable resistors that change with temperature. If you had the time and patience, you could attach an ohm meter to it and heat up the sensor and let it cool while watching the meter. A new one is about $30 if I recall correctly.
