Well if the temperature sending unit isn't working the there isn't usually a way to fix it other the installing a whole new sensor. Those sensor go bad from time to time and shouldn't be too hard to replace.

Remove the intake duct. Find the two cables leading into a hose and into the engine. The cable that is closer to you is the thermal transmitter; the one behind that is the CTS. Remove the old CTS and install a new one using an adjustable wrench. Reattach the wire and reinstall the intake duct and air box.

You must replace the sensor on the side of the thermostat housing. Buy a new sensor from a parts store like napa or carquest.
