How to Restore the Mileage Range on a Car?
2 Answers
Car's mileage range cannot be restored on its own and requires professional restoration at a 4S shop. Generally, if the vehicle's mileage range disappears, it may be caused by a car circuit or dashboard malfunction, and it is recommended to conduct timely inspection and repair. Mileage range can also be referred to as endurance capability, which indicates the total distance a vehicle or ship can continuously travel under maximum fuel reserve. For electric vehicles, the mileage range refers to the distance traveled from a fully charged state of the power battery to the end of the test as per standard regulations, and it is also an important economic indicator for electric vehicles.
Restoring the range on a car depends on the specific situation. I often encounter such issues when helping people repair cars, mainly falling into two categories: inaccurate system readings and actual low range. If the dashboard shows errors, such as erratic fuel gauge or battery meter readings, try a soft reset—turn off the engine, wait a few minutes, and restart, or pull out the relevant fuse and plug it back in after a while. The system might recover. For electric vehicles, disconnecting the main battery for a few minutes and reconnecting it can reset the battery management system. Another common cause is sensor failure or aging circuits—check for clean and corrosion-free connector contacts. If that doesn’t work, professional diagnostic tools are needed to scan and clear fault codes. For daily maintenance, keeping tire pressure optimal and the air filter clean can actually improve fuel efficiency and extend driving range. Don’t forget regular maintenance—check these components during oil changes to avoid recurring issues.
