How to eliminate the yellow engine light on a Sail?
1 Answers
The yellow engine light on a Sail indicates a fault in the engine, and it is necessary to promptly visit a 4S shop or repair shop to use a computer diagnostic tool to retrieve the fault code and identify the issue. Generally, it may be a fault with a certain sensor. Another possibility is a fault in the fuel system, which requires cleaning. Cleaning the engine mainly refers to cleaning the fuel system and the lubrication system. More details about the engine are as follows: 1. Fuel system: It primarily involves the mixing of gasoline and air to form a combustible mixture. Gasoline itself contains impurities, and there is dust in the air. After combustion under high temperature and pressure and oxidation with the atmosphere, carbon deposits are produced. If these carbon deposits are not cleaned in time, they can lead to various faults, such as difficulty in starting a cold engine, engine shaking, lack of engine power, increased fuel consumption, excessive exhaust emissions, and other adverse phenomena. 2. Lubrication system: If carbon deposits are not cleaned in time, they can cause various faults, such as blocking the lubrication oil passages in the engine, leading to dry friction in the engine, contaminating new engine oil, reducing the various performance characteristics of new oil, corroding metal, decreasing the engine's sealing performance, reducing cylinder pressure, increasing engine wear, and other faults.
