What is the reason why the engine light of Fit car is on?

There are many reasons why the engine light of Fit car is on. It is recommended to go to a repair shop or 4S shop for inspection and maintenance.

The engine lights up for the following reasons:

Poor gasoline quality will lead to insufficient combustion of the mixture in the cylinder, which will lead to pollution of the lamp and easy to produce carbon deposition. The existence of carbon deposit at the air inlet and piston top will lead to poor atomization, insufficient combustion and light pollution. When the cold car starts, especially when the weather temperature drops sharply, the pollution lamp will light up because of the temperature correction problem of the computer.

If the mileage of the engine is too long, the working characteristics of the spark plug will be weakened, leading to the lighting of the pollution lamp. Too much carbon deposition will lead to reverse breakdown of the ignition coil, resulting in failure of the ignition coil, poor ignition and incomplete combustion polluting the lamp. Excessive vehicle age and mechanical aging lead to poor engine working conditions and pollution of lamps. Part of the sensor computer board itself failed, resulting in pollution of the lamp.

Precautions for automobile engine maintenance are as follows:

Replenish enough cooling water to lay a good foundation for engine cooling. Check whether the thermostat is normal. The thermostat can't open the big valve in time as required, so it must be replaced in time. Pay attention to the indicating reading of the water thermometer at any time while driving, and it is required not to exceed 95℃. When the engine is started in cold state, it is necessary to warm up the engine. Use fuel that meets the requirements.

When the amount of oil in the fuel tank is kept at 1/3 as far as possible, it is necessary to refuel, so as to make the gasoline pump in the fuel tank dissipate heat well and ensure that the gasoline pump has a long enough life. Maintain the engine regularly, maintain the engine according to the mileage on time, and choose the appropriate engine oil. Keep the coolant clean, so that the engine has good heat dissipation. Clean the oil and gas circuits of the engine regularly.
