How to Check the Fuel Gauge?
2 Answers
To check the fuel gauge: 1. When the illuminated bars reach the 'F' position, it indicates the tank is full; 2. The closer the illuminated bars are to the 'E' position, the less fuel remains, signaling the need for timely refueling. The fuel gauge is designed to indicate the amount of fuel in the car's tank, with its low fuel warning system activating when the fuel level drops below a certain threshold, alerting the driver to refuel. Reasons for inaccurate fuel gauge readings include: 1. Poor contact or severe wear of the fuel level sensor's sliding resistor; 2. Abnormalities in the instrument circuit or loose/aged electrical components; 3. Deformation of the fuel tank or abnormal bracket positioning; 4. Loose connections or open circuits within the engine control module; 5. Loose grounding wires of the vehicle's fuel level sensor or fuel pump wiring harness.
When getting into the driver's seat after work to prepare for driving, I habitually glance at the fuel gauge on the left side of the dashboard. The traditional analog fuel gauge has two letters, E (Empty) and F (Full), and seeing the needle pointing to the three-quarter mark near F tells me that the tank was recently filled. Newer models with LCD screens are more intuitive—the fuel pump symbol is accompanied by a digital range display. Seeing '420km' of remaining range gives me peace of mind to start the car. I remember last month when driving a friend's Tesla, I fumbled around for a while looking for the fuel gauge, only to finally find the real-time battery percentage hidden in the energy management page on the central display. Developing the habit of checking the fuel gauge before starting the car and filling up before long trips helps avoid the embarrassment of running out of fuel midway.
