How to connect a digital water temp gauge on a adaptor ? The digital water temp gauge is on an adaptor . The function of the water temperature sensor is to convert the temperature of the cooling water into an electrical signal, which is input into the ECU to correct the fuel injection quantity . Increase the fuel injection when the temperature is low. Correct ignition advance angle . The ignition advance angle shall be increased at low temperature, and delayed at high temperature to prevent deflagration. Affect the idle speed control valve . At low temperature, the ECU controls the action of the idle speed control valve according to the water temperature sensing signal to increase the speed. The digital water temp gauge is an important data of the working state of the automobile engine. When the engine works normally, the temperature of the digital water temp gauge is about 90 degrees.

When the temperature of the car is too high, it may indicate that the engine has failed. When the engine temperature is too high, it will also cause failures in other parts, causing a series of problems. There is no water temperature gauge, and there is a water temperature indicator light on the car. When this indicator light is on, it means that the car engine is overheating, and you need to stop and turn off the engine, and then wait for a while. When the water temperature and engine temperature drop, continue driving. Generally, this indicator will not light up unless the car has been driving for a long time or there is a problem with the car itself. Not only Jetta and Santana do not have water temperature gauges, but also some BMW models do not have water temperature gauges. Therefore, water temperature gauges are not necessary. You can also use cars correctly by looking at the water temperature indicator.

Stop to check if the water temperature is too high or rises too fast. The water temperature gauge is used to display the temperature of the engine coolant. When the temperature is too high, it will flash to remind the driver that the coolant is too high, in order to prevent the thermal fatigue damage caused by the failure of timely cooling of the internal parts of the engine when driving with high temperature, which will affect the safety of the driver!
