This is a manual car. The probably started out of no where. The car started sputtering a few minutes after gas light went on, which we were hoping was the issue. We added gas and the problem persisted. We popped the hood, checked oil and all fluids, they were fine. Started the car again when are was felt coming from the CHT sensor and we saw it popped out. We tried replacing it and the cover and started the car again and the second the car started the part popped out. Not sure what would cause the malfunction.
SOURCE: Engine coolant temperature sensor
get a name brand sensor and double check with scantool under engine data for correct temp , if you can , use infrared temp gun and compare with scanner reading
SOURCE: My 95 Taurus Sho 3.2L, stalls every day. All
Will it stall if you keep your foot on the gas like the Idle speed is set low? Possible Idle speed motor? I'll have to look up the location of the low coolant sensor.

have u bled the cooling system ?warm the car and cut the car off right before the fans come on ,let sit for 30-35 minutes,see if the coolant drops in res. if so repeat process untill coolant stops droping ,then drive car regularly if overheating stops ,but monitor it because it will drop somemore/there has been reports of new and rebuilt water pumps nt having correct propelar mounted on them/ backwards etc. if this helps let me know [email protected]

With the sensor unplugged and the fan works,, replace the new sensor,,,,, it is probably defective. I have seeh this before.

The coolant temperature gauge sensor is a temperature-variable resistor, or thermistor. As coolant temperature increases, the resistance of the sensor decreases or decreases, depending on the type of sensor.
A1 and A2 platforms use a different type of circuit that A3 vehicles. On A1 and A2 vehicles, the circuit is a "resistance to ground" type. A3 vehicles use a "variable voltage" type, where a voltage is supplied to the sensor. Because of the circuitry design on A3 vehicles, testing of the coolant temperature gauge is limited.
The engine coolant temperature gauge uses a heat sensitive sending unit to transmit an electrical signal to the gauge. The sending unit is a heat sensitive variable resistor that is located on or near to the cylinder head and threads into an engine coolant passage. The sensors are a Negative Temperature Coefficient (NTC) type. As the temperature increases, the electrical resistance of the sensor decreases. As the coolant temperature changes, so does the resistance of the sensor. The gauge is calibrated within the operating range of the sensor and interprets the resistance value to display the coolant temperature.
Beginning with model year 1994, the engine coolant gauge and the Engine Control Module (ECM) temperature sensors were combined into one sensor with 4 terminals. The basic operation remains the same in that their resistance decreases as the coolant temperature increases, however the actual resistance values of the 2 sensor circuits are different. The electrical connector of the 4-wire terminal sensor ( 1 and 2 ) is keyed to prevent improper connection of the sensor's electrical circuit.
