What Causes the Engine Yellow Warning Light to Illuminate in a Car?
1 Answers
When the engine yellow warning light illuminates, it indicates a fault in the car's engine. Below are specific explanations regarding engine faults: 1. Engine Misfire: If the engine misfires, the engine fault light will turn on. A misfire can lead to insufficient power, poor acceleration, and abnormal vehicle shaking, requiring prompt inspection at an auto repair shop. 2. Severe Engine Carbon Buildup: Heavy carbon deposits in the engine are a primary cause of the engine fault light and reduced vehicle power. Severe carbon buildup can disrupt normal fuel combustion. 3. Engine Overheating: Prolonged overloading of the engine can trigger the car to reduce power as a self-protection measure. In such cases, simply wait for the engine temperature to drop to the standard range. 4. Poor Fuel Quality: Using low-quality fuel or mixing different types of fuel can cause the engine yellow warning light to illuminate and result in insufficient power. It is necessary to promptly clean the fuel tank and refill with high-quality fuel.
