What should I do if the MIL fault light is on? How to solve the problem that the mil fault light is

The sensor itself is damaged;

2. The line connection is unreliable;

3. The plug is soaked in water or other foreign objects;

4. The signal disk of the crankshaft position sensor is abnormally runout;

5. There are iron filings at the end of the sensor test.

The dashboard shows that the MIL is an engine fault that needs to be repaired by a maintenance master.

The car dashboard is a device that reflects the working conditions of each system of the vehicle. Common ones are fuel indicators, cleaning fluid indicators, electronic throttle indicators, front and rear fog light indicators and alarm lights. Different cars have different gauges.

However, the conventional instruments of general automobiles include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc.

The full name of MIL is Malfunction Indicator Lamp, which stands for Engine Failure Lamp.

When the mil fault is displayed, it may be that the engine is faulty, and the best way is to go to the store as soon as possible and let the master extract the fault code for troubleshooting.

MIL LIGHT MALFUNCTION INDICATOR LAMP Abbreviation for Fault Indicator!

If the engine fault light is on, the main reason is the throttle.

or excessive carbon deposits inside the engine, and oxygen sensors.

After the failure, the mixture is out of proportion, and the engine failure light is easy to turn on. This is related to excessive carbon deposition on the throttle valve or carbon deposition contaminating the sensor. If you drive at low speeds in urban areas for a long time, it is easy to form carbon deposits, which can lead to this phenomenon.

Then it's possible that it's because of the high voltage line.

The insulation layer is easier to be broken down after aging, which causes the engine fault light to be on, because the control unit self-diagnosis system generally does not make fault code indication on the high-voltage line, it is more difficult to find when similar problems occur, and it is necessary to use a special diagnostic computer for a special car with experienced maintenance personnel to carry out a comprehensive detection.

How to solve the problem that the mil fault light is always on? How to solve the problem that the mil fault light is always on? mil stands for Fault Indicator.

When the vehicle fault indicator lights up, if the engine is checked and found that there are obvious oil, gas and circuit faults, and does not affect the normal driving, you can choose the right time to go to the maintenance station, if the existing fault affects the normal driving, you must immediately go to the maintenance station for maintenance, do not blindly overhaul yourself. The solution to the mil fault light is to change the throttle to make the engine accelerate and decelerate slowly if the conditions permit, if the driving feeling is not much different from the feeling under normal circumstances, the cause of the fault light is not serious, the driver can decide whether to repair it immediately according to the situation, but the time should not be delayed for too long, so as not to further aggravate the degree of failure.

If in the engine acceleration and deceleration test, it is found that the speed transition is not smooth, the rate of change is slower than usual or even the throttle is not controlled, first pull over the vehicle, then turn off the ignition switch, get out of the car and carefully observe the engine's oil circuit, gas circuit and circuit, to see if there is obvious oil leakage, air leakage and the phenomenon of the connector of the wiring harness falling off. @2019

When this fault light is on, it may be that some sensors are faulty, or some of the sensors may be dusty and the data is inaccurate.

There are many electronic systems in the car, and the normal operation of the car is inseparable from the electronic system.

There are a lot of sensors in the car, and the engine has a computer. This computer can collect information through sensors and then control the engine to work through actuators.

If the sensor fails, the data received by the computer will be inaccurate and the motivation will not work properly.

It is normal for electronic systems to have some malfunctions after long-term use. If an electronic system fails, the computer will malfunction**.

When the car is serviced, the technician connects to a diagnostic computer, which can read the fault** and help the technician quickly determine the cause and location of the fault.

In the event of an occasional malfunction**, it can be rectified directly by the diagnostic computer.

During normal maintenance, a technician can use a diagnostic computer to read the fault** so that they know what is wrong with the car's electronic systems when they are in the hands of the celery.

If the car's electronic system fails, it should be repaired immediately, otherwise it may affect the normal operation of the engine.

When you usually use the car, you must maintain it regularly and check it regularly, so that you can keep the car in good condition all the time.

MIL stands for Fault Indicator. When the vehicle fault indicator lights up, if the engine is checked and found that there are obvious oil, gas and circuit faults, and does not affect the normal driving, you can choose the right time to go to the maintenance station, if the existing fault affects the normal driving, you must immediately go to the maintenance station for maintenance, do not blindly overhaul yourself.

In the process of driving, it is found that the fault indicator light becomes brighter, if the conditions permit, change the throttle to make the engine accelerate and decelerate slowly, if the driving feeling is not much different from the feeling under normal circumstances, then the fault that causes the fault light to shine is not a serious failure, the driver can decide whether to repair it immediately according to the situation, but the time should not be delayed too long, so as not to further aggravate the degree of failure, if the engine acceleration and deceleration test is done, it is found that the speed transition is not smooth, The rate of change is slower than usual or even the throttle is not controlled, first pull over the vehicle, then turn off the ignition switch, get out of the car and carefully observe the engine's oil circuit, air circuit and circuit, to see if there is any obvious oil leakage, air leakage and the phenomenon of the connector of the wiring harness falling off.

Normally, when the "mil" indicator is on, the engine does not immediately limit the output torque for safety reasons, leaving a buffer period (or a certain mileage) to give the driver more time for repairs or maintenance, and when the vehicle meets the torque limit, it becomes sluggish. If the red "STOP" indicator lights up at the same time in addition to the "MIL" light, then it means that the engine has a serious fault and the vehicle should be stopped immediately and repaired in time. In addition, although the vehicle can be driven for a period of time when the "mil" is on, we should also drive the vehicle to the repair station as soon as possible, if left unchecked, it is likely to cause permanent damage to the aftertreatment system in the long run, and the gains outweigh the losses.

After this fault light is on, it may be caused by the failure of some sensors, or it may be caused by dust on the surface of some sensors that cause inaccurate data.

There are many electronic systems in the car, and the normal operation of the car is inseparable from the electronic system.

There are a lot of sensors in the car, and the engine has a computer, which can collect information through the sensors, and then control the engine through the actuator.

If the sensor fails, the computer will not receive accurate data and the engine will not work properly.

It is also normal for the electronic system to have some failures for a long time, and if the electronic system fails, the computer will generate a fault code.

When repairing the car, the technician will connect to the diagnostic computer, which can read the fault code, which can help the technician quickly determine the cause and location of the fault.

If it is some occasional fault code, it can be eliminated directly with a diagnostic computer.

During normal maintenance, the technician can use the diagnostic computer to read the fault code, so that the car's electronic system can know in time what is the problem.

If there is a malfunction in the car's electronic system, it should be repaired immediately, otherwise it may affect the normal operation of the engine.

When using the car in ordinary times, it is necessary to maintain it regularly and check the car regularly, so that the car can always be kept in good condition.
