When the yellow light in a car comes on, it is generally a fault reminder or maintenance reminder. There are many types of yellow lights on the car dashboard, including the engine fault light, oil fault light, tire pressure fault light, transmission fault light, and maintenance reminder light. When the yellow light comes on, it usually indicates that there is a fault in the car, and the vehicle should be inspected and repaired based on the type of fault light. Additional information: 1. There are many reasons why the engine fault light may come on, including high engine temperature, engine misfire, engine knocking, severe engine carbon buildup, or poor fuel quality. 2. When the fault light comes on, there are two scenarios: First, although the light is on, there are no abnormal sensations while driving, and acceleration and braking are normal. In this case, the car can still be driven normally. It might be due to a temporary sensor malfunction, interference from external conditions, or a fault that does not affect driving but may impact emissions. In this situation, you can continue driving temporarily but should visit a 4S shop for inspection as soon as possible. 3. The engine fault light coming on is a common issue faced by many car owners. It looks like a yellow light shaped like a faucet. Faults in the car's electrical system, various sensors, or control modules can cause the engine fault light to come on. More accurately, the engine fault light is part of the emission system. When the engine control unit detects a faulty sensor that may cause emissions to exceed standards, the fault light will illuminate.
