Air or combution gasses being forced into the cooling system from a blown head gasket or cracked head can cause the same symptoms.If you want to know if the temperature sensor is working, you must first be certain that the rest of the cooling system is working and only then can you determine if the sensor is "lying" to you. The actual engine temperature should be checked with an infrared thermometer and compared to the temperature sensor data in the onboard computer.There is a coolant temperature sensor for the computer and there is a separate coolant temperature sending unit for the gauge. Comparing the two and verifying with an infrared thermometer is the best way to figure out what is going on.
