On my '95, the sensing thermistor is in front of the radiator near the bottom. It goes to terminals 9 & 10 on the OH console. The wires are Dk Grn/Red (9) and Lt Grn/Wht (10).
A thermistor changes resistance with temperature. Cold = high ohms, Hot = low ohms. If you put an ohmeter across the sensor and heat and/or cool it you'll see the resistance vary. If it is 0 ohms or infinite ohms, the sensor is faulty. Thermistors come in hundreds of values, I do not know what the sensor value is supposed to be. Go to the P n P and buy one for 50 cents.
If you go to Radio Shack and buy a ~50,000 ohm potentiometer, You can feed that into the console with the sensor unplugged. Turn the pot and see the readout change. If it doesn't change, the console is faulty.
Hope this helps
