What's with the camera on the dashboard?

What appears on the dashboard is not the logo of the camera, but the logo is similar to the pattern of the camera. This sign is the engine fault light.

The reason why the engine fault light is on is:

1, poor combustion state;

2. Engine knocking;

3. Poor fuel quality;

4. The engine cylinder is not clean and has carbon deposit;

5. The computer can't get the engine data.

The engine fault light is on, or it may be that the fuel pump is not recording oil and the car can't start, so it can't start directly; It is also possible that the oxygen sensor is faulty. In this case, you can still drive normally after getting off the bus, but it will lead to deviation in the control of engine air-fuel ratio and consume more oil than before.

Another possibility is that the fault light is on, which is a false fault. This possibility is still relatively large. For example, if you drive a family car, you just came to a high-speed cross-country in the mud, or you are curious about what a plug is for, the ECU will give a warning (fault light) for this improper operation. In fact, there is nothing wrong with the car, just troubleshoot it.

Hazards of engine fault lights;

1, poor automobile exhaust quality, polluting the environment;

2. The increase of automobile fuel consumption wastes petroleum resources and RMB resources;

3. The temperature of the combustion chamber increases and the wear intensifies, which may lead to early engine damage;

4. Engine burns engine oil;

5, the engine noise increases, affecting driving and riding comfort.

When the engine fault light is on, the following measures should be taken: First, check the water thermometer and the oil pressure warning light. If the water thermometer and the oil pressure warning light do not give an alarm, the car can still be driven, but at this time, we must pay attention to controlling the speed and drive to the maintenance station for inspection in time.

If the water temperature is too high or the oil pressure warning light is on, if it is obvious that the vehicle is out of order, you should immediately pull over and call the maintenance station for rescue to avoid affecting the engine performance.

Extended data:

Interpreting the indicator light of automobile dashboard;

1, front and rear fog light indicators

This indicator lamp is used to display the working status of the front and rear fog lamps. When the front and rear fog lights are turned on, these two lights will also be turned on. When visibility is low in foggy weather, it is necessary to turn on fog lights. What needs to be reminded here is that fog lights have strong penetration ability, so don't turn them on unless necessary. Especially in rainy days, fog lights are easily refracted and reflected by water droplets, which affects the sight of drivers in front and rear, causing safety hazards.

2. Constant speed cruise indicator light

At present, some models are equipped with cruise control devices. When this function is started, the cruise control light is on, and the general color is green. Theoretically, cruise control can save fuel by controlling gasoline injection, but starting cruise control in urban areas and other road sections that need frequent braking and deceleration may consume more fuel.

3. Warning light of electric steering system

The warning light of the electric power steering system lights up continuously after turning on the ignition switch or during driving, indicating that there is a fault in the electric power steering system. The yellow indicator light is on, indicating that the steering system is partially failed and more force is needed to turn the steering wheel.

The red indicator lights up, indicating that the steering system is completely out of order and its function has failed. It takes a lot of force to turn the steering wheel. What is needed is that if the engine is restarted and the indicator light goes out after a short period of driving, there is no need to send it for repair.

4. Tire pressure warning indicator light

The tire pressure warning light is on, indicating that the automobile tire is leaking, which may be because the tire is leaking. Of course, the sudden drop in temperature may also cause the warning light to light up. If it is the latter, it is ok to add some gas, and some models may need to reset the tire pressure in the computer.

5. Water temperature warning light

The water temperature warning light is used to indicate whether the coolant temperature is normal. Under normal circumstances, it goes out, and it will light up if the coolant temperature is too high or too low. Under normal circumstances, the water temperature warning light is on because of insufficient cooling water, and it can return to normal after adding cooling water.
