Why Does the Driving Range Increase?

[StElena]

The driving range displayed on the dashboard is calculated by the vehicle's onboard computer based on the remaining fuel, indicating how many more kilometers the car can travel. The driving range is determined by the amount of fuel, which in turn is measured by the fuel level sensor. Therefore, it can be concluded that the driving range depends on the fuel level sensor. The fuel level sensor, commonly referred to as the fuel float, is installed inside the fuel tank and detects the amount of fuel based on the fuel level. Here are some common issues related to the fuel gauge: 1. If the fuel tank is half full but the fuel gauge suddenly drops to zero after driving for a while: This is likely a fault with the fuel float. The fuel float operates similarly to a potentiometer or a sliding rheostat. If the "sliding rheostat" shorts at a certain position, this issue may occur. The solution is to remove, clean, or replace the fuel float. 2. If the fuel gauge remains stuck at a certain position and does not decrease even after driving a significant distance: Check if the fuel float is stuck in a particular position. Remove the fuel float and test the flexibility of the float arm by moving it up and down. If it is not flexible enough, clean or replace the fuel float.
