The logo on the dashboard will light up when the car starts

Engine fault indicator, this light is on when the ignition switch is turned on for car self-inspection, and this light is off when the engine of the car is started, if this light is on or flashing while driving, it means that there is a problem with the engine and should be stopped for inspection. If you confirm that the engine oil pressure, water temperature, fuel system, and ignition system are all right, turn off the main power supply first, and stop for a while to turn on and start the engine to see if it is still on. If it is still on, you should go to the repair station to check the fault.

When this light is on, you should feel that there is no obvious change in the power of the engine, if it affects the power, it means that the engine is malfunctioning, and it may be a small problem with the circuit or computer without affecting the power.

Hello, when the key door is opened normally, all the signs on the dashboard will be lit, and the normal system will be extinguished in turn after the self-test, until the car is started, all the signs will be extinguished, if it is not extinguished, it means that the system has a fault and needs to be repaired.

Hello, after the vehicle key door is opened, the dashboard enters the self-test state, and all the warning lights on the instrument will be lit, which is a normal phenomenon, and these warning lights will go out after the vehicle engine starts.

When the vehicle is in the self-inspection, many fault lights will be lit, and it will be extinguished after the fire, which is very normal.

Hello, depending on your situation as well as our repair experience, the moment of start-up will be. The vehicle will self-check, all the lights will be on, but it will go off after the self-inspection, I hope mine will satisfy you. Happy car.

If the engine icon on the dashboard is always on, it means that there is a fault, that is, the fault light, at this time, you can take off the negative pole of your car's battery. Wait a minute or two before putting it on him, and it'll usually be fine.

Sensors 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 engine data, at this time it will cause the engine fault light to turn on.

If it is just started, it is normal, and the driving computer has not detected the engine when it is just started, and if it is still after a few minutes, it needs to be checked and repaired by the 4S shop.

What's the deal with the engine icon on the dashboard that keeps it on? The yellow engine icon is always lit, indicating that the engine electronic control system is faulty, go to the repair shop or 4S shop to detect what fault code, and then carry out maintenance.

The engine icon light is on, indicating that the engine control system is faulty and needs to be repaired.

The car dashboard lights are fully lit.

The cause of the CAN bus failure, the CAN interface of the ECU is not in good contact.

2.Excessive dirt and carbon deposits, abnormal air circulation, and inability to accurately control the normal air intake volume, resulting in unstable gas levels and making the engine not work well.

3.The low fuel pressure combined with the poor constant pressure performance leads to a low level of atomization in the system, making it difficult for the car to start.

It is recommended that you check the car fault light encyclopedia.

The instructions are clearly written... What does each light mean.

It's not interesting, the engine doesn't start.

No problem, only one is a problem.

The reason for the engine icon to light up is sensor problems, maintenance questions, and oil quality problems.

Sensor Issues:

The sensors mentioned here include water temperature, crankshaft position, air flow, inlet air temperature, oxygen sensor, etc. When these sensors are damaged, poorly contacted, or the signal is interrupted, the car's ECU is unable to accurately obtain data from the engine, resulting in the engine failure light coming on.

Maintenance Issues: Improper engine maintenance is the most common cause of engine failure. All vehicles have a certain maintenance interval. If the driver does not maintain it on schedule, the driving habits are not good, it will increase the burden of engine operation, and finally can only be reminded by the fault light.

Oil quality issues:

The oil quality mentioned here includes fuel and engine oil. Fuel filled in the car is generally labeled, and motor oil can also be divided into semi-synthetic and fully synthetic. Manufacturers will generally recommend which grade of fuel and which type of oil should be used by the driver.

If the driver does not add as required, the chances of starting the manuscript will wear out in the long run.

If the engine icon is yellow, the problem is not big, go to try maintenance, if the Xun limb fruit is red, it is recommended to go to the maintenance belt Changshi center for repair.

Possible Causes:

The inside of the engine cylinder is not clean and there is carbon deposit: after a certain period of use, some carbon deposits must accumulate 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 knocking. In this case, the engine fault light is also illuminated.

Poor combustion state: Poor combustion state of the engine 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.

Poor fuel quality: 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 stupidity to 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.

The reasons are as follows: 1. The sensor is damaged, the contact is poor or the signal is interrupted, and the computer will report the code if it has a storage function; 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 conditioning filter is blocked, and 8. The engine itself is caused by mechanical failure.

The specific analysis is as follows; 1. Sensor problems; Sensors include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., throttle position, accelerator pedal position sensor, 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 be on, and the power of the engine will also be affected. 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 pass the fault light to remind you 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 hood 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. pressurization issues; Intake booster lines and turbochargers can also lead to engine oil leakage, large oil consumption, and power decline, personal summary for reference.

What does it mean to show the engine logo on the dashboard What kind of car is the car logo The dashboard shows that the engine sign is engine failure, and the reason is that the air flow sensor or oxygen sensor is faulty, spark plugs, etc., check it specifically.

If an engine icon appears on the dashboard, it means that the engine is faulty.

If the engine fault light is displayed on the dashboard of the car, there are many reasons involved, and you need to check to know the reason.

1. Identify the cause of the failure. For diagnostics of such faults in which the engine does not start, the battery should be tested first. It is necessary to find out if the engine does not start because the battery is insufficient.

2. Detect ignition timing. Timing belt slippage is the root cause of the failure that there is no electric spark and the engine cannot start.

3. Detect the starting system. In the case of faults such as engine failure to start, the first thing to do is to check the circuitry in the engine starting system. From the perspective of the most basic composition, the circuit of the starting system generally includes the following basic parts, that is, the battery, the starting motor and the cable connecting these parts.

Of course, in addition to this, ignition switches, starter relays or solenoid coils, as well as in-vehicle anti-theft systems, are also important components of the starting system.

4. Detect the quality of electric sparks. Once the circuitry of the starting system has been tested and proven to be fine-tuned, attention should be focused on why the engine is not working. Generally speaking, the ignition system of the engine is tested first, which is also the easiest inspection job.

In early ignition systems, you could easily remove the ignition coil and use a spark detector to detect if the spark was normal. When choosing a spark detector, an adjustable detector is preferable to a fixed design because it allows you to adjust the detector to a smaller gap so you can tell if there is no spark at all, or if there is an electric spark but it is weak.

5. Detect the fuel system. The diagnosis of the fuel system can be divided into two parts: the diagnosis of the fuel supply system and the diagnosis of the injector circuit system.

The fuel supply system can be detected by measuring the flow and pressure of the fuel. The best way to measure fuel flow is to inspect the line when there is a load in the fuel supply line.

Strictly speaking, the exhaust emission light is on, and there are many reasons why the exhaust gas is not up to standard, such as intake and exhaust, fuel injection, and ignition.

The engine icon is lit to indicate that the engine is faulty and needs to be detected and repaired in time.

This situation may be caused by an air leak in the engine, and the fault information must be read by a diagnostic instrument to determine the specific cause.

Tomorrow night's engine icon, which is a proof that the vehicle is faulty, you need to troubleshoot and find.

Engine failure, oxygen sensor severity, and more.

According to the information you provided, the main cause of this phenomenon is the poisoning of the anterior oxygen sensor.
