Mazda 3 engine fault light is on, what should I do?

The fault light of Mazda 3 engine is on because the carbon deposit inside the engine is too serious, which leads to the warning of the engine fault light of the automobile.

The solution is: go to 4S shop or garage to clean up the carbon deposit inside the automobile engine in time, which can solve the cause of the automobile engine failure and avoid problems in the operation of the automobile engine.

There are many reasons for the formation of carbon deposits in automobile engines. The most fundamental problem is that gasoline is not completely burned and remains in the engine for a long time before carbon deposits are formed. This is not only related to the usual driving habits, but also related to the added oil. If improper or poor quality gasoline is added, it can not be fully burned, and carbon deposit will be formed.

Extended data:

Matters needing attention in the use of Mazda 3 automobile engine are as follows:

When the oil passes through the pores of the oil filter element, solid particles and viscous substances in the oil will accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element smoothly, the filter element will burst or the safety valve will be opened to pass through the bypass valve, bringing the dirt back to the lubrication part.

Contaminants in the air will deposit around the PCV valve, which may block the valve. If the PCV valve is blocked, the polluted gas will flow into the air filter in the opposite direction, and the polluted filter element will reduce the filtering ability. If the inhaled mixed gas is too dirty, it will further pollute the crankcase, resulting in increased fuel consumption, increased engine wear and even damage to the engine.
