What is the problem with Sylphy s engine failure light always on?

The engine failure light is on means that the engine of the car has failed. The fault light only indicates that there is an abnormality in a certain system, as for the specific fault, it also needs to be interpreted with the help of a computer detector, and each brand of car has its own unique fault**.

Interestingly, because computers are controlled through fixed programs, it is inevitable to "make some mistakes", which is often referred to as "false failures".

Because the fault lights are controlled by a microcomputer, no matter which system alarms, there is not much difference in the way of dealing with them in the absence of a computer detector.

Just because the engine fault light is on doesn't mean the engine won't work. First of all, the fault light is on, it is necessary to detect and repair, if it happens to be near the maintenance station, it is best to check it at any time, it is better to check it immediately, if the location is far away from the maintenance station, and there is no time to go to the maintenance station to check, as long as you feel that the engine has no obvious fault, you can do things first.

Possible causes of Sylphy's engine failure light staying on:

1. Check whether the idle motor wiring harness is in good contact, and you can replace the idle motor wiring harness.

2. The three-way catalytic converter is damaged.

3.The oxygen sensor is damaged.

4.Bad knock sensor.

5.Oil problems can also cause engine failures and the lights stay on.

6.Use the car computer tester to test the engine system and read the specific fault code.

Under normal circumstances, it needs to be repaired immediately.

If the engine fault light is on, the cabin has no abnormal sound of limb walking, the instrument has no other abnormal prompts, the vehicle power is not affected, and the gearbox upshift is not affected, you can continue to drive and stop the 4S shop for further investigation, because the intake and exhaust may cause the engine failure light to be on, and the specific problem is analyzed in detail.

As long as there are no special abnormalities in the engine power and sound, it can still continue to drive. Because there is a substitute bug program in the ECU. Once one of the many sensors has a sensing failure, in order to ensure the normal operation of the engine, the ECU will replace the parameters of the faulty sensor according to the pre-set backup parameters to avoid vehicle breakdown.

The reasons why the Sylphy engine fault light is on are as follows:

1. Exhaust emissions are not up to standard: such as poor fuel, failure of three-way catalytic converter, excessive carbon deposit in the intake pipe, blockage of fuel injector, failure of oxygen sensor, occasional lack of fire in the engine, etc., will lead to the lighting of the engine fault light, among which the engine failure light is the most caused by poor oil quality;

2. The fault lamp is lit due to the poor operation of the engine system, such as the accelerator pedal sensor, throttle position sensor, air flow meter, crankshaft position sensor, etc., or the fault of the line sales road is poorly contacted, etc., which will cause the engine fault lamp to be lit;

3. The failure of the transmission system of some vehicles is also indicated by the engine fault light, such as internal failure of the gearbox, skidding, high temperature, etc.

There are three main reasons why the engine failure light is on the following three points:1Exhaust emissions are not up to standard, including poor fuel, three-way catalytic converter failure, excessive carbon deposition in the intake pipe, blocked injectors, failure of oxygen sensors, occasional engine stalling, etc.

These problems can lead to substandard exhaust emissions, which in turn can cause engine failure lights to turn on, with poor oil quality being the most common cause of engine failure lights. 2.Faulty lamps caused by poor operation of the engine system, including faults of accelerator pedal sensors, accelerator position sensors, air flow meters, crankshaft position sensors, etc., or poor line contact.

These problems can cause the engine system to work poorly, causing the fault light to come on. 3.Some vehicle transmission system failures are also indicated by activating the elevator fault light, such as internal transmission failure, skidding, excessive temperature, etc.

These problems can lead to poor transmission operation, which can cause the engine failure light to come on. Therefore, we need to pay attention to check the exhaust emissions, engine system sensors, etc., for troubled obstacles, and transmission problems to avoid the Sylphy engine failure light from illuminating.

There are many reasons why the Sylphy engine failure light is on. One of them is that the engine system is not working well due to substandard exhaust emissions, which causes the fault light to be on. In addition, there are also some vehicles whose transmission system faults are also indicated by engine fault lights, such as internal transmission faults, slippage or high temperatures.

Specifically, the reasons for the occurrence of Sylphy engine fault light indication mainly include the following situations:1Exhaust emissions are not up to standard

Poor fuel, three-way catalytic converter failure, excessive carbon deposition in the intake pipe, fuel injector blockage, oxygen sensor failure, and occasional engine stalling can all cause the engine failure light to come on. Among them, poor oil quality is one of the main reasons for the engine failure light to turn on. 2.

Poor operation of the engine system: If there is an error in the accelerator pedal sensor, accelerator position sensor, air flow meter, crankshaft position sensor and other sensors, or if the line is not in good contact, the engine fault light will turn on. 3.

Vehicle driveline failure: Some vehicles also have transmission system failures that are indicated by engine fault lights, such as internal transmission faults, skidding, excessive temperature, etc. In short, when Sylphy's engine fault light is on, we need to carry out a repair check on the vehicle to find the specific cause and solve it.

The engine fault light is a problem that every car owner can not ignore, which is directly related to engine life and driving safety. Sylphy ( Check price |Detailed explanation of the model The classic engine fault light is on, which means that the engine control system may not be working properly and needs to be repaired, and it is recommended to go to the 4S shop for inspection as soon as possible. So what's going on with the engine failure light on?

1. The quality of gasoline is poor and not up to standard.

Generally, it is because of the addition of poor quality gasoline at non-standard gas stations, resulting in insufficient combustion of the oil-gas mixture and the engine fault light when the engine is working. This will not affect driving safety, but it will be more or less harmful to the engine.

2. Oxygen sensor failure.

Nowadays, there are two oxygen sensors installed in cars, one at the front and one at the front and one at the front of the three-way catalytic converter. The function of the front oxygen sensor is to detect the air-fuel ratio of the engine under different working conditions, while the ECU computer adjusts the fuel injection amount and calculates the ignition time according to this signal. The rear is mainly to detect how well the three-way catalytic converter is working.

Therefore, if the oxygen sensor is damaged or the sensor plug is damaged or loose, the mixture will be too thin or too concentrated, which will cause the fault light to turn on.

3. The air flow sensor is faulty.

The air flow sensor, also known as the air flow meter, detects the amount of air inhaled and converts it into an electrical signal to the ECU of the electronic control unit, which indirectly allows the ECU to decide how much fuel to spray according to the optimal air-fuel ratio. If the air flow sensor or wiring fails, the ECU will not get the correct intake volume signal, and the sock will not be able to control the fuel volume normally, resulting in the mixture being too thin or too thick, and the engine will not work properly. While malfunctioning of the air flow sensor does not cause the engine to fail to start, phenomena such as unstable idling, poor acceleration, flashback of the intake pipe, and black smoke from the exhaust pipe are highly likely.

4. Carbon deposition in spark plugs.

The uneven quality of fuel on the market and the congestion of urban traffic make it easy for automobile spark plugs to produce carbon deposits, which will lead to poor engine work, such as difficulty in starting, unstable idling, poor acceleration, urgent refueling and tempering, excessive exhaust gas, and increased fuel consumption.

5. The engine lacks cylinders.

After the engine lacks cylinders, it will lead to high fuel consumption, black smoke, weak acceleration of the car, serious shaking, engine noise will also increase, and it is easy to stall the vehicle. The lack of cylinders in the engine mainly comes from the ignition system and fuel supply system, including carbon deposition in the spark plug and damage to the high-pressure oil pump.

How to deal with the Sylphy fault light.

The fault light is on, indicating that there is a problem with the car. If it is a red light, it is recommended to find a safe place to park nearby and do not continue driving. If it is a yellow light, if it is not a big problem to open it with your hands, you can slowly drive to the car 4S shop and use the computer to read the fault code.

It is then inspected and repaired according to the corresponding fault**. There is a rule for the lights in the car meters. A red light is usually a hazard warning light.

If these red indicators are on, they will be ignored and will either have a great impact on your driving safety or cause a lot of harm to the vehicle itself. When the warning light of the brake system is on, it will definitely tell you that there is a problem with the brake system. If you leave it on all the time, it can lead to serious accidents.

If the airbag warning light is on, it is certain that there is something wrong with the internal system, and there is no way to protect you if something goes wrong. If the oil pressure warning light is on, continuing to drive will cause great damage to the engine, and the direct consequence is that you cannot drive at that time. This is a red warning light.

A yellow light is a fault indicator. When the yellow light in the instrument cluster is on, the driver is informed that a system of the vehicle is out of function before completion. For example, the ABS warning light is on, which directly means that the ABS is no longer working, and it may cause the wheel to die when braking.
