A yellow light in a car is generally a fault reminder or maintenance reminder. There are many types of yellow lights on the car dashboard, mainly including the engine fault light, oil fault light, tire pressure fault light, transmission fault light, and maintenance reminder light. Below are the specific introductions for different fault lights: 1. Engine fault light: Engine temperature too high, engine misfire, severe engine carbon buildup, poor fuel quality, or sensor damage. 2. Oil fault light: Insufficient engine oil, excessive oil viscosity, blocked or improperly adjusted pressure relief valve, or insufficient oil volume. 3. Tire pressure fault light: Insufficient or excessive tire pressure, or the tire pressure light not being reset. 4. Transmission fault light: Blocked transmission valve body, transmission sensor fault, or transmission controller fault. 5.
