When the engine coolant temperature is higher than the predetermined value, if the radiator cooling fan is not running, you should check the radiator cooling fan circuit. First check the wiring connections, check for open circuit, short circuit, and the work of the Working fan relay and thermal ferrite temperature sensor.
Check Shaft Position Sensor thermal ferrite. The thermal ferrite temperature sensor placed in the container, connect the multimeter, while heating at work to check the sensor. Under normal conditions, when the coolant temperature is the predetermined temperature, the sensor is in a conducting state, the meter indicates 0 Ω. Coolant temperature is higher than the predetermined temperature, the sensor should be turned off (non-conducting sensor), the meter indicates the resistance ∞, if the number of the ferrite temperature thermal sensor is damaged and should be replaced.

Working principle of temperature sensors

Working principle of temperature sensors1, the thermal resistance: in accordance with the principles of the resistance wire of the temperature change
2, a thermocouple: a two conductor contact, the junction will have a stable electromotive force; same conductor ends at different temperatures, between the both ends of the electromotive force of a certain size
3, liquid thermometer: is the use of temperature-sensitive liquid thermal expansion of the principle of work
Most of Car Temperature Sensor resistive sensor,
That is, he himself is a resistor, as the temperature changes, the corresponding change in the resistance value, the resistance change of the desired temperature and Crank Shaft Position Sensor is a linear relationship, but which does not actually exist, the general performance to have good linearity within a certain temperature range performance. So when you want to select the temperature sensor for specific models of the original operating temperature range.
