1) Diagram and pin
2) Installation position
Installed in the cooling water flow rate is high, and can correctly reflect the engine cooling water
temperature, such as the water outlet of the engine or the engine cooling system circuit.
3) Working principle
The two NTC thermistor is encapsulated in the temperature sensor, the resistance value varies with
the temperature of the cooling water, cooling water temperature is low, the resistance of the
thermistor is large. The cooling water temperature is high, the resistance of the thermistor is smaller.
Conversion of resistance into the change of voltage input to the ECU, ECU according to the
temperature of cooling water, the basic injection time, carries on the revision to the idle speed and
the air volume. On the other hand, it also output signals to the instrument, the driving staff can
directly by visually judge the operating state of engine.
As shown in Figure 6 structure temperature sensor
