Excuse me, is it normal for the engine indicator and oil indicator to turn on when the car is not st

Normal, after turning on the electricity, if the engine is not started, both lights will be on, and the engine will not be lit when the engine is started. If it is still bright when it is started, it is faulty.

If these 2 lights are still on after the vehicle starts, it means that the engine is faulty and the oil is faulty, such as insufficient oil pressure, insufficient oil, etc., you need to check it.

Engine fault indicator.

The engine fault indicator is represented by check engine or mil, it has two statuses and indication contents, one is solid, indicating that the engine electronic control system is faulty; The other is flickering, which indicates that the fault is still affecting some kind of engine performance (e.g. exhaust emissions, etc.).

Hello is normal, rest assured to use,

Normal, as long as you don't have it after getting in the car, it's fine.

Hello, this is a normal system self-test.

Hello, normal, thank you for your support to the car master and have a great life.

The system self-test or disassembling the battery causes the fault light to be cleared with a decoder, and the engine fault light is usually on for the following reasons:

1. The combustion state is not good.

Poor engine combustion condition is the main reason why the engine failure light is on.

2. Engine knocking.

There are usually three scenarios:

The first case: the car is weak;

The second case: the car is weak and the engine noise is too loud;

The third case: there is an obvious knocking sound.

In the first case, some engine fault lights will turn on, some will not, and in the second and third cases, the engine fault lights will inevitably come on.

3. The internal reason why the engine failure light is on.

1) The fuel quality is not good.

2) The inside of the engine cylinder is not clean and there is carbon deposit.

First of all, the most common reason: less oil. In order to reduce the frequency of oil lamp alarms, it is recommended that car owners:

Do not use oil that is lower than the quality grade specified in the owner's manual; It is also necessary to develop the habit of checking the oil regularly, and check the oil usage every 2,000 kilometers. The oil sensor plug (oil pressure sensor) will alarm when the oil reaches the bottom line or below the specified bottom line, and the oil light on the dashboard will definitely light up at this time, and the solution is very simple: add oil.

However, if the oil sensor plug is broken, the oil lamp will also give an alarm.

Another reason: damaged oil pump. The function of the oil pump is to increase the oil to a certain pressure and then force it to the moving surface of each part of the engine.

When the oil pump is broken, you need to stop the engine immediately and contact the tow truck or insurance company for rescue. [When buying car insurance, the insurance company will have free rescue, free gasoline or tire change, and electric service].

There is also a possibility: the oil pipe is damaged, the oil pipe is responsible for the normal transportation of the oil, if the oil pipe is damaged, it will cause the oil to be unable to be transported normally, and the oil lamp will also alarm.

Of course, there is also a situation that the oil used is not good, there are too many impurities in it or the viscosity is not enough, and the oil lamp on the dashboard will also become brighter. Special attention should be paid here: once the oil light is on, the vehicle must be parked in a safe place, the vehicle must be turned off immediately, and wait for rescue.

Otherwise, the engine will fail due to lack of lubrication, and in serious cases, the engine will need to be overhauled.

Another reason is that the engine temperature is too high, and the reasons for the high engine temperature are nothing more than too much scale, poor heat dissipation, long-term overload operation, or too late oil supply, etc., which will make the aging and thinning of the oil faster, leak from the gaps of each fit, reduce the pressure, and the fault lamp of the engine oil will naturally light up.

Another reason why the oil light is on is a faulty oil filter. Once the oil filter is blocked, the bypass valve on its base will be opened, and the oil at this time will directly enter the main oil channel without filtration, if the opening pressure of the bypass valve is set too high or too low, the pressure of the oil pump will rise or fall, and the alarm light will also be on. Then there is a failure of the oil bypass valve, the pressure of the oil will be reduced when the pressure regulating spring is softened or adjusted improperly, and the mating surface between the valve seat and the steel ball is worn or stuck and closed tightly.

The oil's faulty light will also come on.

The last thing to note is that when the engine is working, the oil pressure is generally kept in the pressure range of 150 350kpa, and when the oil pressure is too low or too high, the oil indicator light on the dashboard on the car will light up.

The engine fault indicator is generally a problem fed back by the sensing system, such as the air flow meter and the oxygen sensor have been missing, which will cause the engine fault light to be lit, and if there is a problem with the oil, it will indirectly cause the engine indicator to be lit, such as the oil pressure is insufficient for a long time, which will cause excessive wear of the cylinder block, and will also cause the engine and oil lamp to be lit.

Hello, this depends on the amount of engine fault lamp or oil pressure only, if it is the fault of the engine then it has nothing to do with the oil.

The engine temperature is too high, and the reasons for the high engine temperature are nothing more than too much scale, poor heat dissipation, long-term overload operation, or too late oil supply time, etc., which will make the aging and thinning of the oil faster, leak from the gaps in each fit, reduce the pressure, and the fault lamp of the oil will naturally light up.

This indicator light should be used to read the fault ** with a diagnostic computer, and determine what problem caused the fault light is on according to the fault**, so as to accurately prescribe the right medicine.

The engine failure light is usually lit for the following reasons: Poor combustion state: Poor engine combustion state is the main reason why the engine failure light is on. Engine knocking, the first case: the car is weak, the second case: the car is weak, the engine is noisy.

You mean you just changed the oil and then the engine lights came on, right? If this is the case, it is not possible to be sure, and the relationship between them cannot be determined, so it is better to go to the repair shop and test it with a fault diagnosticator.

It does not matter. Each time the vehicle is powered on, the engine self-test indicator will light up, which means that the engine is undergoing self-test. The indicator light will turn off when the vehicle is started, indicating that the engine is normal and there is no fault.

The engine fault light is lit, most of them are caused by lack of oil, you can go to the repair shop to check whether your vehicle has a problem with burning oil.

It generally doesn't matter if you change the oil filter regularly, go to the repair shop and check the fault code.

will light up. The oil indicator is used to show the oil stock and pressure in the engine, and its color is mainly red or yellow, twist the key, the indicator will also light up when the vehicle conducts self-inspection, and the indicator will automatically turn off after starting the car.

If the indicator light is always on, the reason is that the oil stock and pressure are lower than the standard value, the red light of the oil pot on the instrument is lit, if it is not a sensor failure, it is generally the lack of engine oil in the engine, and continue to drive in the absence of oil, which will cause the piston to break the cylinder body, and there is a danger of stalling.

The reason why the engine failure light is on.

1. The combustion state is not good.

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.

2. The fuel quality is not good.

Many riders who find that the engine fault light is on have a feeling: that is, the engine fault light suddenly turns on after adding a tank of fuel. Because the engine has requirements for the quality index of oil, especially as the requirements for the engine are getting higher and higher in various specifications, the quality index of the oil is also getting higher and higher.

3. The inside of the engine cylinder is not clean and there is carbon deposit.

After a certain period of use, there must be some carbon deposits inside the engine, which itself will lead to changes in the design parameters of the engine, and at the same time, its properties are unstable and heat is accumulated, and these accumulated heat will lead to disorderly ignition of the engine, thereby causing engine detonation. In this case, the engine fault light is also illuminated.

The engine fault light is on the solution.

1. Clean the engine.

Once the engine failure light is on, the owner should clean the engine in time, and there are currently two correct cleaning methods:

1) Go to the repair shop to clean the carbon deposits with a special cleaning agent.

2) Clean the entire fuel system with good fuel additives, including removing carbon deposits in the cylinder.

2. Add higher grade gasoline.

After the engine cleaning, because the compression ratio of the current automobile engine that meets the national IV emission standard is generally above, this kind of car is not suitable for long-term gasoline below 95. In order to keep the engine in good working condition, the owner can choose to add 95 or 97 gasoline, which can usually solve the problem of the engine failure light on.

3. Improve fuel quality.

Since the domestic fuel cannot meet the requirements of the current high-efficiency engine for the time being, it is necessary to improve the quality of the fuel by yourself. For example, using good fuel additives to improve the cleanliness level of fuel should be the best way.

The engine fault light will not be lit when there is no oil, because it is not an engine failure, and the reasons why the engine fault light is lit include system and circuit abnormalities such as air intake, ignition, and exhaust emissions, and do not include no oil. The combustion state is not good, and the engine combustion state is not good, which is the main reason for the engine failure light to be on.

The cause of the oil lamp alarm.

1. The oil volume of the engine oil is insufficient, so that the oil volume of the oil pump is reduced or the pump cannot be oiled due to air intake, resulting in the oil pressure dropping;

2. The engine temperature is too high, which is easy to make the oil thinner, from the fit gap.

Medium and large losses lead to a drop in oil pressure;

3. Crash. When the oil pump parts are damaged or the gap is too large due to wear and assembly, it will cause the failure of the oil pump not producing oil or insufficient oil output;

4. a crankshaft. Improper matching gap between large and small tiles, too tight will increase the oil pressure, too loose will reduce the oil pressure;

The engine fault light will not light up when there is no oil, because this is not an engine failure, and the reasons why the engine fault light is lit include air intake, ignition, exhaust emissions, etc., which are caused by rubber pants and circuit abnormalities, and do not include no oil. The poor combustion state of the engine is the main reason for the engine failure light to be lit.

The engine fault light is on, which means that the engine computer detects that the engine has one or several sensors, or the induction plug is caused by poor burning.

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.

Car Indicator Classification:

1. Engine fault indicator.

The engine fault indicator is indicated by check engine or loss of years, it has two states and indication contents, one is always on, indicating that the engine electronic control system has failed; The other is flickering, which indicates that the fault is still affecting some kind of engine performance (e.g. exhaust emissions, etc.).

2. Brake warning light.

The brake warning light is red and the pattern is a circle with a "! Symbols.

For reference, 1. Sensor failure; 2. The quality of gasoline is not up to standard; 3. The air leakage of the inlet pipe leads to the mixture being too thin; 4. The fuel pressure is low, and the injector and fuel filter are blocked; 5. The signal of the pressure sensor and the throttle position sensor is abnormal; 6. The signal of the sensing liquid tank device is abnormal, resulting in inaccurate ignition timing and late ignition; 7. Weak high-voltage sparks due to poor spark plugs, igniters or high-voltage wires; 8. The throttle is dirty; 9. The exhaust gas recirculation system works poorly; 10. The exhaust pipe is blocked; 11. The cylinder pressure is low; 12. Turbocharging system failure 13. Clutch three-piece set 14 Air filter blockage, piston ring break or stuck, poor valve sealing, late ignition time, carburetor mechanical failure, air intake pipe leakage, individual cylinders do not work well or do not work, etc. However, some of the faults of insufficient engine power can be solved by use. Such as:

The general wear of the cylinder is high, and the flow of the carburetor oil channel is not smooth. When the user reflects that the engine power is insufficient, when the oil is burned, we should first judge the cause of the lack of power, in the exclusion of the air filter blockage, the carburetor throttle can not be fully opened, the ignition timing is not good, the intake pipe gasket is damaged, the individual cylinder does not work or does not work well, and then according to whether the engine fuel consumption is too high to judge the carburetor working condition, if the fuel consumption is too high, the exhaust smoke is very thick, it is likely that there is a mechanical failure such as the volume hole falling off, this fault must be repaired as necessary. Finally, we have to judge the wear and tear of the engine cylinders.

Engine wear directly affects the tightness of the cylinder; The most convenient way to check the tightness of the cylinder is to use a cylinder pressure gauge to check the compression pressure of the cylinder.
