What is the situation where the car engine fault light is on?

If there is a problem with the air intake system, there will be poor combustion and the engine fault light will turn on.

The problem with the sensor is mainly due to the damage to the oxygen sensor, water temperature sensor, crankshaft position sensor and air flow sensor, or when the contact is poor, the driving computer of the car cannot obtain the relevant data of the engine, resulting in the engine failure light to light up.

And the engine fault light is on, which is usually caused by the following reasons. Poor quality of gasoline, substandard. Poor quality of gasoline (such as excessive impurities, excessive collagen content, excessive sulfur content) will not only cause the mixed gas to burn insufficiently in the cylinder and produce excessive carbon accumulation, but also have hidden dangers of blocking oil lines and corroding components (such as fuel pumps, etc.).

The reasons why the engine alarm light is on are as follows: Sensor problems: the sensor includes water temperature, crankshaft position, air flow, air intakeTemperature, oxygen sensors, etc. When these sensors are damaged, the contact is poor or the signal is interrupted, the ECU of the car cannot accurately obtain the data of the engine, which will cause the engine fault light to turn on.

What should I do if the car engine fault light is on?

1. Identify the cause of the failure. For the diagnosis of such faults that the engine cannot start, the battery should be detected first. It must be clarified that the engine cannot start because the battery is underpowered. Detect the ignition timing.

2. [Pacific Automobile Network] When the engine fault light is on, the vehicle should be started and turned off. After starting and turning off the car three times, start the vehicle again and observe whether the fault light is still on. If it is still on, you need to go to the repair shop in time to check the fault code and check whether it is an engine problem. It's still a sensor failure.

3. Once the fault indicator light turns on, stop and check as soon as possible. Drive the car to the roadside or other safe places without affecting other vehicles and turn off the engine. Open the hood and check the engine for odor, smoke or other abnormalities.

4. The elimination method of the car engine fault light is as follows: pay attention to whether the engine is running normally, whether there is jitter, black smoke and other problems, and if so, try not to start it again. Special note that you must not start it again when the red light is on.

What is the reason why the engine fault light is on?

When the sensor is damaged, the contact is poor or the signal is interrupted, the engine fault light will turn on. Poor engine maintenance is the most common reason for engine failure. Therefore, it is suggested that the car should be maintained on time and maintain good driving habits, otherwise it will increase the burden of engine operation.

The specific reasons why the engine alarm light is on are as follows: sensor problems: sensors include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or signal interruption, the ECU of the car cannot accurately obtain the engine data. At this time It will cause the engine fault light to light up.

If there is a problem with the air intake system, there will be poor combustion, and the engine fault light will turn on.

There are many reasons why the engine fault light turns on. Here are some possible reasons: Sensor problems: This includes water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc.

The reasons for the engine fault light are: poor quality of gasoline, oxygen sensor failure, air flow sensor failure, spark plug carbonization, and engine explosion.

The reason and solution for the yellow light of the car engine

The reason why the yellow light of the dashboard engine is on Sensor problem The sensors mentioned here include water temperature, crankshaft position, airFlow rate, 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 is the reason why the yellow light of the car engine is on? When the car engine is not working normally and the self-diagnosis system has no fault code output, it is especially necessary to rely on the operator's inspection and judgment to determine the nature of the fault and the part where the fault occurs.

The owner found that the engine fault light suddenly turned on during the driving process. If there is no urgent matter, he needs to find the nearest repair shop to check the cause. Generally speaking, the reasons for the engine fault light to light up are poor quality gasoline, oxygen sensor failure, spark plug carbonisation and water temperature sensor damage, etc. .

The specific reason why the engine fault light is yellow, including but not limited to the following aspects: Sensor failure: The sensor in the engine system is responsible for monitoring various parameters, such as oxygen sensor, temperature sensor, oil pressure sensor, etc. When any of the sensors fails or the reading is abnormal, the engine fault light will be triggered.

The reason and solution for the yellow light of the engine fault light Oil quality problem: If the oil quality does not meet the standard, it will also lead to insufficient combustion of oil and gas mixture when the engine is working. In the long run, it will cause the engine to wear and cause the engine fault light to turn on.

The car engine fault light is on. What is the reason?

The specific analysis is as follows;Sensor problem; 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.

The problem of oil, it is necessary to choose the appropriate oil and gasoline according to the characteristics of the engine. There is a problem with the sensor of the vehicle, causing the fault light to turn on. Problems with spark plugs or lines will lead to insufficient combustion of the engine mixture. Maintenance problems, or too much carbon accumulation will also cause insufficient combustion.

If there is a problem with the air intake system, there will be poor combustion, and the engine fault light will turn on.
