Hot sale electric water temp gauge and sending unit! The alarm light for high water temperature is usually installed on the electric water temp gauge and is judged and controlled by the water temperature sensor. However, some of the high water temperature warning lights are independent. In this case, the signals they use may be from the water temperature sending unit, or from the temperature control switch (water temperature sensing plug), similar to the original control of the Computer fan. When the switch is closed during high temperatures, the control alarm light will light up and give an alarm. 

Function of the car water temperature sending unit: 1. Function: To obtain the temperature of the engine cooling water on the side. The electronic control unit measures the temperature of the engine cooling water based on this change, and the lower the temperature, the greater the resistance; On the contrary, the smaller the resistance. 

Symptoms of malfunctioning water temperature sensor: abnormal display on the vehicle's water temperature gauge, unstable idle speed, and weak acceleration. 1. The water temperature sensor of the vehicle has malfunctioned, with the most obvious manifestation being the abnormal display of the water temperature gauge. The pointer of the water temperature gauge has remained stationary for a long time, and it may have been in a low or high temperature state, while the vehicle has not experienced any abnormalities. 2. If the water temperature sensor of the vehicle malfunctions, it can also cause the vehicle to experience unstable idle speed. When the water temperature sensor malfunctions, it will not sense the transmission signal of the mixed gas and cannot provide mixed gas to the engine, affecting the stability of the engine. 3. The water temperature sensor of the vehicle has malfunctioned, causing the vehicle to experience weak acceleration and affecting the fuel injection rate of the engine, thereby increasing the fuel consumption of the vehicle. 

When the water temperature sensor is broken, it will affect the normal operation of the vehicle. At this point, the indicator needle of the car's water temperature gauge is stationary and will point to the highest position. In addition, it is difficult to start a cold car because the water temperature sensor is damaged, and when the cold car starts, it displays the temperature signal of the hot car. At this time, the electronic control unit cannot receive the electrical signal of the excessively rich mixed gas, but can only provide the engine with a relatively sparse mixed gas.
