fuel level sensor a circuit high
The fuel level sensor a circuit high. It is recommended to check the circuit and the fuel level sensor. The sensor is installed on the high-pressure main pipe to directly measure the fuel temperature flowing through the return pipe. The density and viscosity of the fuel change with the fuel temperature.
The ECU corrects the fuel flow according to these data. In the return line from the fuel pump to the fuel cooler. It is used to detect the fuel temperature. The engine electronic control unit uses the fuel temperature signal to calculate the injection starting point and injection quantity.
The fuel level sensor is on the valve water cover pad. If the voltage of the fuel level sensor is too high, there will be strong gas flowing in the engine, and the fault codes erased by the computer will continue to appear. Therefore, the voltage of the sensor is too high, and the fault can be solved only by replacing it with a new one.
This is a problem with the oil level sensor. The sliding resistance on the oil level sensor of the gasoline pump is broken and needs to be replaced.
Analyze possible causes according to fault codes:
1. Fuel gauge sensor failure.
2. Fuel pump control unit fault (CST engine).
3. There is a fault in the harness from the instrument to the fuel sensor.
4. The instrument itself is faulty. Since the fuel gauge sensor has been replaced, it can be basically eliminated. Use a multimeter to measure according to the circuit diagram.
How to solve it ? Remove it and sand it with sandpaper. It can be used as soon as it can be used. If it can not be used, it needs to be replaced. According to the fault code b103e1b, check the controller under the rear seat, and then replace the sliding resistance on the fuel level sensor of the gasoline pump. (Note: the fuel position sensor is located on the right side of the fuel tank.)
After the battery is fully charged and unloaded, take a universal meter to measure the voltage of the battery, and then measure the voltage two days later. If there is a big difference, it may be that there is damage inside the battery, electrolyte flows out, and the power will slowly decrease. Check whether there is something wrong with your circuit, such as short circuit or wrong wire connection.
