What does the triangular exclamation mark in a car indicate?

[StMiranda]

The triangular exclamation mark in a car represents the traction control system warning light. The reasons for its illumination include: 1. Faulty engine oxygen sensor; 2. Clogged fuel injector; 3. Carbon buildup on intake valves; 4. Sensor malfunction; 5. Low fuel pressure; 6. Inaccurate air measurement; 7. Impurities in gasoline. The functions of the traction control system are: 1. To provide optimal traction under various driving conditions; 2. To enhance driving stability, acceleration, and hill-climbing capability. The working principle of the traction control system is: The system uses a computer to monitor wheel speed and steering wheel angle. When accelerating, if the computer detects an excessive speed difference between driven and non-driven wheels, it sends signals to reduce engine fuel supply, thereby decreasing driving force.
