1. The engine failure caused by the oxygen sensor is bright
The may want to be higher in the engine lighting fault light. For the case when it is bright, the probability of the problem of the oxygen sensor is relatively high. Generally, the oxygen sensor can be used for 3 years or longer. For new cars, engine failure yellow lights may wish to check whether the oxygen sensor plug is loose.
This solution: Check whether the oxygen sensor plug is loose before and after, and the oxide blocking causes the oxygen sensor to clean it with a carburetor cleaning agent or dilute the sulfuric acid iron. It can be replaced by the damaged oxygen sensor.
2, the oil caused by the engine fault light
The some reasons are some of the gasoline with poor quality at the irregular gas station, which causes the oil and gas mixed burning to combine sufficiently. It will affect driving safety, but long -term use is more or less harmful to the engine.
This solution: You can use a special tool to use a special tool to pull out the gasoline in the fuel tank at the 4S shop, and then replace it with high -quality gasoline.
3, carbon accumulation caused fault lights to light up
Due to the incomplete fuel and congested urban road conditions on the market, spark plugs can easily form carbon accumulation, often easily lead to poor engine work, so the fault light lights light up Essence
It solution: Check whether the spark plugs have carbon deposits and use a copper brush to erase. You can also use the oil circuit cleaning and the dry ice of the engine cylinder according to the situation.
The above three situations are relatively common. In addition, the engine fault light is turned on the accelerator. It may be that the oil pump (filter) is blocked or the fuel pump is damaged. If the vehicle continues to drive, there is a risk of breach of anchor. The blocked fuel filter element and fuel injection mouth represent the obstruction of the oil road. In addition to increasing fuel consumption, it is also prone to accelerate weakness and idle jitter.
With the development of science and technology, the car now produces various indicators or alarm lights in the instrument panel. When the engine or related parts fails, the indicator light on the car instrument will light up, which will prevent a prevention of prevention. In the first inspection role, let's talk about what is the cause of the engine fault light to light up.
It may be a problem with the engine -related sensor, and there are multiple sensors on the engine, water temperature, crankshaft position, oxygen sensor, air intake temperature, air sensor, etc. When these sensors are faulty or damaged, and poor contact or in good contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or poor contact or inquisitor When the signal is interrupted, the ECU of the car cannot correctly receive the signal data sent by the sensor, and the engine fault light will light up at this time. There is also inadequate mixed gas burning. For example, failure such as spark plugs, fuel pumps, and oil circuit blocks will cause insufficient combustion. detected.
The air intake problem, engine work requires a combination of air intake and gasoline to form a mixed gas. In this process, the filtering of air filter elements is particularly important. Long -term intake impurities may also cause engine fault lights to light up. There is also the lump of fuel jets and carbon deposit with throttle. If the gasoline is not clean and has impurities, it will gather at the fuel jet mouth to affect the normal work of the fuel injection mouth. Carbon accumulation will be produced. When the throttle is accumulated, when it reaches a certain degree, it will affect the normal switch of the throttle, which will also cause the engine fault light to light up.
Summary: Generally speaking, if there is no problem with the engine oil pressure, water temperature, fuel system, and ignition system, you can turn off the power first, rest for a while, and start the engine to start the engine to see if it is still bright In order, if so, then you better go to the repair shop to read the engine failure code.
Sensor problems: water temperature, crankshaft position, air flow, air intake temperature, oxygen sensor;
engine maintenance problem;
oil quality problems: fuel and engine oil;
Failure, ignition coil failure, fuel pump failure, oil circuit block, etc. will cause the engine's hybrid gas to combine poorly.
The red indicator light means warning. At this time, it should be stopped and maintained. The yellow indicator is just a warning, and it can be handled as soon as possible. The blue indicator warned the owner to pay attention to the influence, such as the opening of the high beam will not cause dazzling vehicles. The green indicator is functional lights, such as near -light lights, wide lights and turning lights.
