fresh water tank level gauge sensor
The fresh water tank level gauge sensor is mainly used to detect the level of antifreeze in the water storage tank. The float changes the resistance value to detect the liquid level. First, if the water level sensor is installed on the car, it is also called the liquid level sensor. It is generally installed in antifreeze tank, brake oil tank and oil float in oil tank, but the name is different and the working principle is the same. The liquid level is determined by detecting the liquid level, and then changing the internal resistance value to compare with the resistance value set inside the engine computer board. If the liquid level is too low, the engine computer board can judge the change of the liquid level by detecting the change of the resistance value. When the liquid level is too low. The liquid level sensor transmits a signal to the engine computer board. When it is detected, the engine computer board will control the indicator light in the instrument to light up, telling the driver that the liquid level is too low to add or to add. You need to go to the 4S store or the repair shop for a key inspection. The water level sensor has a very wide range of applications. It is widely used in industry, households, electricity and other aspects. It is a very common sensor.
The function of the water level sensor is to automatically transmit whether the water level reaches the set water level (in fact, when the water level reaches the set water level, the electrical contact inside the water level sensor is connected, and the electrical signal when the water volume reaches the set water level is sent to the computer board, which is the computer board will issue a command to close the water injection and stop the water injection). The water level sensor is broken because the water injection is out of control (water injection is continuous).
Generally, there is a sensor at the position from the water inlet pipe of the water tank to the engine, which is the water temperature sensor. If it fails, it will have a great impact on the engine. Because all cars today are EFI vehicles, this sensor will affect the fuel injection volume. Therefore, low temperatures may cause the engine to start when it is not easy to get on and run unstably after getting on because of the lean mixture.
