4age bt water temp gauge sensor

• 2022-11-03

The normal water temp gauge sensor include the M14 and M16, 4age bt car driver can select which he needs. Water temperature sensor is an extremely important sensor in automobile. At low temperature, ECU can control the action of idle speed control valve according to the water temperature sensing signal to increase the speed. In some more and more high-end cars, the role of water temperature sensor is more and more important. A suitable and stable water temperature sensor can effectively improve the overall performance of the car , such as 4age bt .

The 4age bt water temp gauge sensor has no structural change, but its function is to provide an analog signal of temperature change to the engine control unit. Its power supply voltage is 5V provided by the control unit, and the signal returned to the control unit is a linear change signal of 1.3V-3.8V. The 4age bt water temp gauge sensor main function is to tell the current temperature of the engine control unit. On the contrary, its signal is very important to the control unit. It is mainly because the engine has different working modes under different operating temperatures.

When the temperature is below 86 ℃, the engine shall inject 10% more fuel than the normal temperature to rapidly heat up the engine and reduce the low temperature wear of the engine. When the temperature rises above 86 degrees, the engine shall be sprayed with less oil and the temperature shall be regenerated slowly. So its role is very important. If he has a problem, he will send a wrong signal to the engine control unit. For example, when the car warms up, he will send a low temperature signal from the engine. Does your car spray too much oil, so it seems to have a little waste oil.

Some advanced car engines will have multiple water temperature sensors, one of which is responsible for providing the reference of fuel injection quantity. If this is the case, the engine may continue to provide fuel injection in the "failure mode", so that the driver can drive to the garage for maintenance. Modern cars do not necessarily use water temperature sensors to display the water temperature of the engine. I also said that a certain sensor may be a reference for fuel injection. If so, once it is damaged, it will be difficult to start the vehicle.
