fuel level sensor golf 4
Golf 4 has a fuel level sensor (actually, it is an oil float) to signal the amount of fuel left in the instrument fuel tank , which is generally in the form of a sliding rheostat . Some vehicles also have a sensor for the oil level alarm light , which is generally installed at the bottom of the gasoline pump . When the golf 4 fuel amount is lower than the oil level alarm light sensor , the resistance of the oil level alarm light sensor changes due to no fuel immersion, and the fuel alarm light is turned on . Prompt the driver to refuel in time.
If the golf 4 fuel level sensor in the tank fails, replace it with a new one . The golf 4 fuel level sensor is a part that detects the position (height) of the oil in the container by changing the capacitance between the sensor housing and the sensing electrode after the oil enters the container and turning this change into a current change . If the pointer of the oil gauge does not move , the golf 4 fuel float is generally broken . It is recommended to connect the two lines of the oil float . If the pointer of the oil gauge reaches the top , the oil float is broken . If you still do not move it , check the circuit and instrument panel .
If the golf 4 fuel level gauge pointer does not move just after filling the tank , the golf 4 fuel level sensor float is pushed to the top of the tank by the buoyancy of the oil , and the pointer connected to the sensor will not move . When a little fuel is consumed , the oil float drops , and the pointer will move with the sensor . Extended information : The automobile instrument is composed of various instruments and indicators, especially the driver's warning light alarm, to provide the driver with the required automobile operation parameter information. According to different working principles of automobile instruments , they can be roughly divided into three generations. The first generation of automobile instrument is mechanical movement watch . The second generation of automotive instruments is called electrical instruments . The third generation is full digital automotive instrument , which is a networked and intelligent instrument with more powerful functions, richer display content and simpler wiring harness links.
