This may be due to low battery voltage. It is recommended to check it as soon as possible. If the battery light on your car's dashboard lights up, it means the car battery has a problem. Theyellow lightis on, indicating that the battery is low or dead.
This will prevent the car from starting. At that time, you can start it using an electrical device and run it for a while to store electricity after starting; try again, the yellow light will disappear and the battery will return to normal. If the red light comes on, it is not just a battery problem, but a fault in the power supply system. At this time, it is recommended to turn off the car's electrical equipment and call for help.
Causes why the battery light turns on
1. The voltage generated bythe engine is lower than the battery voltage, the generator does not work or the power line is faulty, the car battery light will turn on. At that time, you should go to the repair shop to check the generator and charging line.
2. The battery light on the dashboard is a warning light indicating that the generator is not producing electricity. Typically, it turns on after turning the ignition switch to the ON position and turns off after starting. engine. If the light is still on after the car is turned on, it means the generator may not be producing electricity or there may be a problem with the wiring and you need to go to the gas station. maintenance for maintenance.
If the generator does not generate electricity, during the process of driving the car, the electrical equipment can only rely on the battery for powerelectric entation, and the battery will not be charged when battery power is used. the engine stalls or the car does not start.
3. When the car battery is low, the battery indicator light will also light up. However, you can continue to use it in this case. Because the battery can be charged by the generator inside the engine while the car is driving.
For reference only: 1. If the sensor is damaged, has poor contact or the signal is interrupted, the computer will report the code if it has a storage function; 2. The engine is; badly maintained ; 3. Fuel and oil quality is poor; 4. Insufficient combustion of the mixture; 5. Spark plug failure, ignition coil failure; 6. Fuel pump failure, oil circuit blockage; . Mechanical failure of the engine itself.
The specific analysis is as follows: 1. Capt problemseurs; sensors include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., throttle position, throttle position sensors the accelerator pedal, when these Sensors are damaged, contact When the signal is bad or interrupted, the car ECU cannot accurately obtain the engine data. At this time, the engine fault light will turn on and the engine power will also be affected. 2. Maintenance Problems: Poor engine maintenance is the most common cause of engine failure. We know that vehicles have a certain maintenance cycle. If the owner does not maintain it on time and has poor driving habits, it will increase the load on the engine operation. Ultimately, the trouble light can only be used to remind you. you need to take care of your vehicle.Love your car 3.Oil quality problem; The oil grade mentioned here includes fuel and engine oil. We know that fuel filled in cars is usually labeled, and engine oil is also divided into semi-synthetic. and entirely synthetic. Manufacturers generally recommend car owners to use what type of label. Fuel, what type of engine oil, if the car owner does not add it as required, it will cause long-term engine wear , so no one can blame it if the error light comes on. Poor combustion of the mixture; engine spark plug failure, ignition coil failure, fuel pump failure, oil circuit blockage, etc. will all lead to poor combustion of the engine mixture. Improper combustion of the mixture will cause carbon deposits or knocking problems in the engine, which willnt possibly detected by the engine oxygen sensor, after signaling to the computer, the fault light will naturally light up to warn of intake problems; Combustion in the engine is necessary. In this process, the air filter element is very important. If the car's air filter element is not clean and is not cleaned regularly, it will affect the car's air intake. time, it is likely to become clogged. In severe cases, the engine trouble light will illuminate. Overeating problems; The intake boost pipeline and turbocharger can also cause the engine trouble light to illuminate. The most common is damage to the turbocharger. At the same time, the vehicle will also experience oil leaks, heavy oil consumption and reduced power. My personal summary is for your reference.
