The dashboard engine of the car is a red light, but can the car drive?

1. A red light on the engine means that the engine is in an emergency state. Do not continue to drive. You should immediately pull over under safe conditions and contact the maintenance agency to confirm the engine status.

2. If the light of the dashboard is damaged, it needs to be replaced in time; if the power supply line of the instrument panel is broken, if there is a break or short circuit, it will also cause the dashboard of the car to not be lit; if the power supply fuse of the dashboard of the car is broken, there will naturally be no power supply, and the dashboard will not light up.

3. Small glfunction. There is no particularly obvious fault in the engine. According to the computer detection information and further inspection, it is found that there is really some kind of fault, which does not affect normal driving or has a small impact. It needs to be found and solved in time. For example, the failure of the air intake pressure sensor, etc. Major failure.

4. However, the engine electronic control unit has a set of spare systems. When the actuator or sensor in the electronic control system fails, it is temporarily spared. At this time, the engine can also be used, but the operating performance. Weakening, this time is called the mother-in-law state, at which time you can drive the vehicle to the repair shop for repair.

5. Water temperature alarm light Water temperature fault light sign, displayed on the dashboard, indicating that the engine water temperature is too high and there is a fault problem. The cause may be the lack of water in the water tank, the failure of the water temperature sensor, and the failure of the water circulation cooling system.You should stop and check at this moment, otherwise the engine may be damaged.

6. Various signal indicator lights will be displayed on the dashboard of the car. When the car engine fault light keeps on, the owner doesn't know what's going on. So what's wrong with the engine fault light turning red? There is too much carbon in the engine.

The 18-speed engine turns on the red light, showing what's wrong with the manual start of the engine?

The reason why the fault light of the speed engine is on is that the carbon accumulation at the top of the air intake and the piston leads to poor atomization, resulting in insufficient combustion and turning on the pollution light. Solution: Clean up the accumulated carbon.

Like our vehicles, there are usually many sensors, and the more common ones areWater temperature sensors, oxygen sensors, etc. When the sensor is damaged or has poor contact, the engine fault light will turn on.

The reasons why the Maiteng engine fault light is on are as follows: ignition system failure, start-up system failure, fuel injection system failure; intake system failure, ECU failure, oil problem, oil lubrication system failure.

Sensor failure: The sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or the signal is interrupted, the ECU of the car cannot accurately obtain the engine data, which will cause the engine failure light to turn on. .

What's wrong with the engine turning on the red light

1The common reasons for the engine red light are as follows: the oil pressure is insufficient, and the oil pressure warning light is on. When this warning light is on, it means that the oil pressure is insufficient. After the oil pressure is insufficient, if you continue to drive, there will be a risk of damaging the engine because the engine cannot be fully lubricated. Serious need to repair or replace the engine.

2. There are many reasons for automobile engine failures, including sensor failures, such as water temperature sensors, crankshaft sensors, oxygen sensors, etc. There are also spark plug failure, ignition coil failure, fuel pump failure, oil blockage and other fault lights.

3. It is possible that a sensor failed once and is now fine, or the interference of some external conditions, or the failure does not affect the driving of the vehicle at all, but may have a certain impact on the emission.In this case, you can continue to drive for the time being, and take the time to go to the repair shop for testing.

4. Engine high temperature: If the engine is overheated while the vehicle is running, it may cause the red light to turn on. In this case, you need to immediately drive the vehicle to the safe area, stop and wait for the engine to cool down. Insufficient oil pressure: If the oil pressure is insufficient, it may cause the engine to fail and display the manual start message.

5. There are two common cases of engine red light: the first is that the oil pressure is insufficient, and the oil pressure warning light is on. When this warning light is on, it means that the oil pressure is insufficient. After the oil pressure is insufficient, if you continue to drive, there will be a risk of damaging the engine because the engine cannot be fully lubricated.

6. Sensors include water temperature and crankshaftPosition, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or the signal is interrupted, the ECU of the car cannot accurately obtain the engine data, which will cause the engine fault light to turn on.

What's wrong with the flashing of the red light on the dashboard after the engine starts

1. The car can't start and the display flashes. It should be that the battery is low. It is recommended to replace the new battery in time or use Other cars can be replaced with an electric start to replace a battery. 1 The car dashboard indicator light flashes and can't start. It is the engine alarm. The car engine causes the fault light to turn on. 2 The fault light is on.

2. The voltage of the car battery is insufficient. Note that the battery voltage is low, not the power outage.Although the car battery is charged, the voltage is insufficient. In this case, the speaker can make a sound normally, but it cannot be started. The battery of the car is dead. For example, you forget to turn off the headlights when parking, or the electrical appliances in the car are not related, resulting in a power outage.

3. The red light keeps flashing in the following situations: water temperature meter alarm light. The alarm light of the water temperature meter is on, indicating that the water temperature of the car is too high. Check whether the engine is boiling and whether there is water leakage. After waiting for the car to cool down, add water to cool down. The oil indicator light is on.
