Why is the average fuel consumption not displayed on the Buick LaCrosse?

[JuliaDella]

Abnormal fuel gauge display in cars is generally caused by issues such as a faulty fuel level sensor (fuel level display sensor) or a short circuit in the fuel gauge wiring. The specific reasons are detailed below: Faulty fuel level sensor: The fuel gauge uses a fuel level sensor to detect the fuel level. If the detection signal is distorted, such problems can occur. Some fuel level displays are controlled by the car's computer, and if the computer signal malfunctions, it may also lead to inaccurate display, though this is rare. A malfunctioning gauge pointer can also result in inaccurate readings. Short circuit in fuel gauge wiring: If the fuel level sensor is functioning properly, the issue may lie in the fuel gauge wiring on the dashboard. In this case, the dashboard should be removed, and a multimeter and a needle should be used to locate and test the corresponding fuel gauge wiring on the dashboard.
