What Are the Hazards of the Engine Yellow Warning Light Being On?
1 Answers
Hazards of the engine yellow warning light being on: 1. Deterioration of vehicle exhaust emissions, leading to environmental pollution; 2. Increased fuel consumption, wasting petroleum resources; 3. Elevated combustion chamber temperature and accelerated wear, potentially causing premature engine damage; 4. Engine oil burning; 5. Increased engine noise, affecting driving and passenger comfort. Once the engine warning light illuminates, it indicates that the engine control unit (ECU) has detected some level of abnormality in the engine. If the engine still shows a yellow light after troubleshooting, it is due to stored fault codes in the vehicle's ECU. Connecting a diagnostic tool to clear the system's fault codes will resolve the issue.
