Can the car still run when the fuel light turns red?

[ElisaAnn]

In fact, under normal circumstances, if the car's fuel tank light turns red, it can still run for about 50 kilometers. The following is relevant information about the car throttle: 1. The function of the car throttle: The throttle in a gasoline engine does not control the fuel injection volume but the opening size of the throttle valve. That is, a smaller opening means less mixed gas enters the cylinder, resulting in less power output from the engine, and vice versa. 2. Solutions for a heavier throttle: If the car's throttle becomes heavier, you can perform a fuel system cleaning. Alternatively, try to continue accelerating to see if the engine speed increases but the speed does not. If this happens, it may be due to a damaged sensor inside the transmission, causing the overdrive gear to be locked.
