How to solve the problem of Lavida engine failure light always on 20

Oil leakage may be the relationship between the oil products, the imported car uses domestic oil for a long time because it is not suitable for the domestic inferior oil may turn on the light, or it may be the oil road, and the specific must be further determined by computer.

If the car is used as usual, and there is no power drop or other problems, it is estimated that there is a problem with the activated carbon canister sensor, and it seems to be more expensive to change this one. This situation is basically to go to the repair shop, there may be a problem with the sensor, or there may be a problem with the car itself, if you are still on the road then you must first check whether the oil and water are less, and then see if the engine temperature is high, whether the engine is running when there is an abnormal sound, whether the battery light is on, if the above are good, continue to open it, but it is also recommended to go to 4S as soon as possible,,, it must be uncomfortable in this kind of illness,

Engine indicator refers to the indicator light used to show the working condition of the vehicle's engine. The indicator light is used to show the working condition of the vehicle engine, when the key door is opened, the vehicle self-test, the indicator light is lit and automatically extinguished, if it is always on, it means that the engine of the vehicle has a mechanical failure and needs to be repaired.

The knock sensor is installed in the middle of the engine block, and the four-cylinder engine is installed between the 2nd and 3rd cylinders, or one in the middle of the 1st and 2nd cylinders, and one in the middle of the 3rd and 4th cylinders. Its function is to measure the degree of engine shake, and to adjust the ignition advance angle when the engine detonation.

It is recommended to go to the 4S shop to use a professional vehicle computer to detect the cause of the failure and fix it, and then clear the fault in the driving computer**There will be no such phenomenon.

The reasons for the failure light of Volkswagen Lavida: 1. The engine oxygen sensor is abnormal; 2. Fuel injector blockage and carbon deposition on the intake valve; 3. False fault phenomenon.

Generally, there are the following reasons: 1. The sensor is damaged, the contact is poor or the signal is interrupted; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. Spark plug failure, ignition coil failure; 6. The fuel pump is faulty and the oil circuit is blocked; 7. The air conditioner filter is blocked.

The specific situation is analyzed as follows; 1. Sensor problems; The sensors mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain the engine data, at this time it will cause the engine fault light to turn on. 2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, and these will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally turn on the fault light to warn of the intake air intake problem; When the engine burns, it needs to take intake, the air filter element is very important in this process, if the air filter element of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be blocked for a long time, and if it is serious, it will cause the engine failure light to turn on. The extender can also cause the engine failure light to come on.

The following are the reasons why the engine fault light of Volkswagen Lavida is on: 1. The engine oxygen sensor is abnormal: the engine oxygen sensor is generally placed near the intake manifold, which will cause the oxygen sensor to be displaced or damaged due to intense driving or some collisions, which will cause the sensor to be abnormal and cause a fault light alarm.

2. Fuel injector blockage and intake valve carbon deposit: There are impurities in gasoline, which accumulate at the fuel injector, which will affect the fuel injection of the fuel injector, and the direct injection engine in the cylinder will directly lead to engine shutdown. The impurities will produce carbon deposits after combustion, and the accumulation of carbon on the throttle to a certain extent will affect the normal opening and closing of the throttle, affect the normal operation of the engine, and cause the alarm light to turn on.

3. ECU feedback error: generally called "false fault phenomenon", it may be due to the loose wiring of some sensors on the car or due to some operations of the vehicle personnel to make the vehicle ECU warn, in this case, you only need to go to the 4S shop to let the maintenance personnel clear the fault code.

The Lavida engine fault light is on, indicating that there is a problem with the engine system. You should use the on-board computer tester to inspect the engine system, read the fault**, and then repair it according to the fault. You should prescribe the right medicine to avoid blindness.

If it is an unexpected failure, clear the fault code with the detector, and the fault light will go out. If the fault indicator is still on after clearing the fault code, the defective part needs to be replaced according to the detected fault content.

Reasons why the engine failure light is on:

1.Poor engine combustion condition is the main reason why the engine failure light is on. In the design of the car, in order to ensure that the engine is in good working condition and ensure the normal working life of the engine, an oxygen sensor is designed and installed on the engine to monitor the combustion state of the engine.

Once the combustion state of the engine is not good, such as high hydrocarbon gas content, high carbon monoxide content, high nitrogen oxide content, Beixiang deficiency These are all bad combustion states, which not only pollute the environment, but also cause fuel waste and excessive wear of the engine.

2.Once the engine fault light is on, it means that the engine parameters have changed, and excessive carbon deposition is one of the main reasons for the change of engine parameters. If this problem is not solved, the combustion state of the engine will never be adjusted to the normal state, and of course, the engine fault light will always be on and will not disappear automatically.

3.When the engine fault light is on, the owner should clean the engine in time. At present, there are two correct cleaning methods: one is to go to the repair shop to clean the carbon deposit with a special cleaning agent. Second, use good fuel additives to clean the entire fuel system yourself, including removing carbon deposits from the cylinders.
