What is the reason for having fuel but the range not displaying?
2 Answers
If the range is not displaying, it could be due to a sensor issue or poor contact. Here are the relevant explanations: 1. Range: The range is data calculated by the computer based on the current fuel level, recent fuel consumption, current driving speed, road conditions, load, and other factors. It is highly influenced by external factors such as road conditions and can vary significantly, serving only as a rough estimate. 2. Sensor: A sensor is a detection device that can sense the measured information and convert it into electrical signals or other required forms of information output according to certain rules, to meet the requirements of information transmission, processing, storage, display, recording, and control.
This situation is quite common. I reckon it's mainly due to a faulty fuel level sensor. The sensor sits inside the fuel tank and over time can get clogged with sludge or debris, or the float inside might get stuck in one position. When the sensor data can't update, the ECU can't determine how much fuel is in the tank, so of course the range won't display. Wiring issues could also be the culprit, like rodents chewing the wires between the sensor and dashboard or loose connectors. Occasionally, the vehicle's computer might freeze up too - restarting the car might fix that. But the safest bet is to get to a repair shop ASAP and hook up a diagnostic scanner, just in case you actually run out of fuel someday while driving.
