Automobile fuel position sensor is an important part of vehicle fuel management system. When the sensor is damaged, it may have the following effects:

1. Inaccurate fuel measurement: The main function of the fuel position sensor is to measure the fuel level in the fuel tank. When the sensor is damaged, it may lead to inaccurate fuel measurement. This will affect the calculation and display of vehicle fuel consumption, which may lead to the driver's inability to accurately understand the remaining fuel quantity of the vehicle and increase the difficulty of fuel management.

2. Vehicle performance degradation: Damage to the fuel position sensor may lead to vehicle performance degradation, such as unsmooth acceleration and insufficient power. This is because the fuel management system of the vehicle cannot accurately monitor and control the fuel supply, which affects the combustion efficiency and power output of the engine.

3. Fault light is on: The electronic control unit of the vehicle usually monitors the working state of the fuel position sensor. Once the sensor is damaged, the fault light of the vehicle may be on. This will prompt the driver that there is a problem, and may cause the vehicle to fail to pass the inspection procedures such as emission inspection.

4. Risk of fuel leakage: In some cases, the damage of the fuel position sensor may lead to the risk of fuel leakage. For example, if the seal of the sensor is damaged, it may lead to fuel leakage in the fuel tank, causing potential safety hazards and environmental pollution.

To sum up, the damage of automobile fuel position sensor may lead to inaccurate fuel measurement, vehicle performance degradation, fault light on and fuel leakage risk. Therefore, once the sensor is found to be faulty or damaged, it should be repaired or replaced in time to ensure the normal operation and safety of the vehicle.
