Fault Characteristics of Car Water Temperature Sensor

Water temperature sensor failure description:
1, the car's water temperature table does not move.
2, ECU temperature signal is abnormal.
3, the body temperature is too high, the cylinder bed burned.
4, burn the engine assembly.
5, the impact Idle speed control valve.

Car water tank temperature control function:
Car radiator, also known as radiator, Is the main engine cooling system components; Function is to distribute heat, Cooling water in the water jacket to absorb heat, Flow to the radiator heat dissipation, And then return to the water cycle, to thermostat function. The car water temperature sensor is to detect the water tank temperature sensor, Is an integral part of the car engine. As a water-cooled engine cooling circuit is an important component. The water temperature sensor can control the absorption cylinder heat, To prevent the engine overheating. due to the larger specific heat capacity of water, Absorption of the cylinder after the heat temperature will not be much, So the heat of the engine through the cooling water the liquid back. The use of water as a heat carrier heat conduction, And then through a large area of the heat sink to convection heat, To maintain the proper operating temperature of the engine.

Water temperature sensor control tank temperature Work: 
     When the engine temperature is too high, The water temperature sensor will transmit the signal to the water tank water pump, Pump water cycle to take this to reduce the engine temperature. To protect the engine's purpose, if the water temperature in winter is too low, This time the water temperature sensor sends the signal will stop the water cycle, To avoid the engine temperature is too low.

Water temperature sensor failure Description:
    Water temperature sensor to read the car static engine (referred to when the cold car) data found, Engine ECU output of the coolant temperature is 105 ℃, At this time (set the temperature in winter) the actual engine temperature is only 1 ℃, Obviously, the engine ECU received the water temperature signal is wrong, Indicating the water temperature sensor has a problem.
As the water temperature sensor failure, Resulting in ECU temperature signal abnormalities, Engine water tank can not open a large cycle, Resulting in the body temperature is too high, The cylinder bed will eventually burn, At that time only for cylinder bed, Serious need to replace the cylinder block, Basically for the engine assembly.

Water temperature sensor fault repair instructions:
Water temperature sensor is a car circuit on the NTC temperature sensor, If the water temperature sensor is broken, Products can not be repaired, only changed. Test the water temperature sensor is normal, The easiest way is to water temperature sensor into the heating cup heating (note that the plug part can not enter the water), With a multimeter "resistance stalls" measurement, When the temperature rises, The resistance should be smaller on the right, If there is no change, It is proved that the water temperature sensor is broken.
