What does the yellow fuel tank light mean?
1 Answers
When the yellow fuel tank light on the car dashboard illuminates, it serves as a warning that the remaining fuel is low or the fuel pump is experiencing high temperatures. Immediate refueling or seeking professional maintenance personnel for troubleshooting and repair is necessary. Typically, when the yellow fuel gauge light comes on, there is still more than 12.5% of fuel remaining in the tank, approximately around 8 liters. The distance the car can travel after the fuel light comes on varies depending on the fuel tank capacity of different vehicle models and driving conditions. When the fuel tank light turns yellow, you should promptly refuel at the nearest gas station to avoid running out of fuel while driving. It is advisable to control your speed reasonably, turn off unnecessary electrical devices in the car such as air conditioning and music, and slightly close the windows to reduce wind resistance. Try to drive on flat road sections and plan your route carefully to avoid taking wrong turns and consuming extra fuel. When the fuel level drops below the fuel pump, the fuel pump lacks sufficient fuel for cooling, and the more fuel is consumed, the more severe the heating of the fuel pump becomes, which can shorten its lifespan. High temperature phenomenon in the fuel pump: Modern gasoline vehicles mostly use electric fuel pumps and electronic fuel level sensors, both of which require immersion in gasoline for cooling. If the gasoline level is too low, the cooling of the fuel pump will be significantly affected, not only reducing the pump's lifespan but also potentially causing fuel line blockages. It is essential to seek professional help to troubleshoot and eliminate safety hazards promptly. During daily driving, it is important to always monitor the remaining fuel level in the tank. This is usually done by observing the readings on the vehicle's fuel gauge. If there are no other issues, the fuel level will be accurately reflected on the gauge. The dashboard fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel midway. During the actual refueling process, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by car manufacturers is measured from the bottom of the tank to the safety limit, with additional space remaining from the safety limit to the tank opening. This extra space is designed to accommodate fuel expansion due to temperature increases without causing overflow. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.
