The car s fault light was on, and there was steam in the front of the car

This is generally a lack of antifreeze, the high temperature caused by adding antifreeze, go to the maintenance plant to check whether the cylinder is pulled.

That could be that the water tank is boiling, and you didn't look at the water temperature gauge? In this case, stop the car and idle for a while, turn off the engine, open the engine cover to cool down for a few minutes, wrap the water tank cover with a wet towel and unscrew it, add purified water, and then go to the repair shop to find out the cause and repair.

If you can clearly feel the vapor in the front of your car, it is likely that your tank is leaking or broken, or that your tank is boiling.

This problem may be caused by the high temperature of the engine, it is recommended to check whether there is a lack of antifreeze, if it does not solve the problem, it is recommended to go to the garage for inspection and repair.

It may be that the cooling pipe is damaged.

Or the valve of the cooling pipe is broken.

When the liquid is heated, it will expand, the door cannot be opened because the water pipe will break, and when the liquid splashes on the engine, it will emit "white smoke" (white fog).

Hello, this may be caused by high engine temperature, you can check whether the coolant is sufficient.

Hello, this may generally be due to the high temperature of the engine, open the engine compartment to see if it is boiling.

Hello, check whether the water tank is caused by water leakage, or if the water tank is steam, it is recommended to go to the auto repair shop to see.

Specifically, depending on what the fault light is, if there is steam in the front of the car, it is very likely that the pot is boiling, check whether the coolant is enough.

Check whether there is a leakage, the cylinder gasket is missing, check it in time, and the computer will read the cause of the failure.

Hello, first of all, it is recommended to check whether the water tank is leaking, or the compressor is faulty, it is recommended to test it

In this case, you may need to check the water tank, could it be that the tank is boiling, or the tank is broken and leaking?

Stop immediately and do not start, and see if there is a lack of oil or water.

Hello, in your case, it should be that there is a leak in your water tank or a leak in the spare kettle. It is advisable to go to the repair shop to check it out.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

This indicator light is on, indicating that the bulb is on a certain part of the car, alerting the guy.

With immediate detection of all lights, most can be extinguished after replacement.

The lights that are often encountered in the car are: turn signals, brake lights, license plate lights, and signal width.

lights, front and rear fog lights.

Reversing lights, high beam headlights, low beam headlights, etc.

If all the lights are basically detected, it is fine, but the faulty lights.

Still bright, there are several possibilities:

1. There is a place where the line is connected virtually, which affects the resistance value of the light line is too large, and the instrument.

The computer mistakenly thinks that the light bulb is not working. 2. Poor line contact.

3. The filament of the bulb seems to be broken.

The light alarm light is on, you can try the following method:

Park your car in a safe place, turn off the engine, and use a wrench.

Connect the negative pole of the battery.

The wiring is removed. Wait 15 seconds, put it on, and see if the faulty light disappears. False.

If it's not lit, it's fine, if it's still on, it is recommended to go to the 4S store or specialize immediately.

In the auto repair shop, the technician can read the fault code with a barcode reader to know the problem. Where is it.

The reason why the car dashboard lights are fully lit.

The CAN bus is faulty, and 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.

Extended Materials. About the car dashboard.

1.The car dashboard is a device that reflects the working conditions of each system of the vehicle. 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.

2.A variety of indicators or warning lights are made under the instrument panel of modern automobiles, such as coolant level warning light, fuel level indicator, washer liquid level indicator, charging indicator, high and low beam dimming indicator, transmission gear indicator, brake anti-lock braking system (ABS) indicator, drive force control indicator, airbag (SRS) warning light, etc.

It is recommended that you use a decoder to decode, find the fault, and then go to the repair shop to find a professional for you to detect and repair, I hope my help to you, hope.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

Engine failure light turns on and off Reason:

1. The instrument prompts that the gearbox is abnormal or the fault light is on, which is generally the alarm when the gearbox fails, and the fault can be determined by computer detection;

2. It may be that the electronic components of the gearbox are faulty, and the solution is: use a computer to detect and replace the damaged electronic components;

3. If the mechanical components of the gearbox are seriously worn, the solution: repair the damaged mechanical components;

4. There is an engine or ABS failure that sends an wrong signal and interferes with the gearbox, solution: detect the engine and ABS, and repair the damaged electrical components.

If the fuel quality is not good, it may also lead to insufficient combustion during driving, and the engine fault light will jump out, but it will not last too long, and if you turn it on again, it will naturally go out. In this case, we don't have to worry, it is very likely that low-quality gasoline has been added. However, the gasoline is filtered by a gasoline filter before entering the combustion chamber, and it will not cause any damage to the engine, so there is no need to pump out the inferior gasoline.

In addition, some old cars have more carbon deposits, and it is easy to cause the engine failure light to turn on, because the carbon deposit itself has adsorption, and when it just starts on fire, if the engine failure light lasts for dozens of seconds, and then extinguishes it is caused by carbon deposits. Because when the car is just started, a part of the fuel injected will be adsorbed by carbon deposits, and the concentration of fuel entering the cylinder will be low, which will cause the lights to turn on.

Finally, after slamming on the accelerator, the engine fault light came on, but after a while, it went off. This situation is because the air intake is not smooth, it may be that the air filter is too dirty and the air filter needs to be replaced.

Summary. After starting, there are many fault lights on the instrument, which means that the vehicle's control system is faulty. It may be that the circuit of the body control module is expected to be loose, and it may be that the circuit board of the engine control computer is connected, or the circuit board of the engine control computer itself is problematic.

You can turn off the engine and restart it, if it still doesn't work, you can disconnect the negative terminal of the battery for a minute and then reconnect it. Take a look at whether these fault lamps can disappear, if it still doesn't work, you need to use the computer to detect, and deal with the maintenance according to the fault of the computer detection.

There will be the following reasons, for reference only: 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 car nuclear He Zen master 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 to dust 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. pressurization issues; Intake booster lines and turbochargers can also cause engine failure lights to illuminate.

The most common of these is turbocharger damage, and at the same time, the vehicle will also have oil leakage, large oil consumption, and power loss.

There are several reasons why the fault light is on, and some of them are not in the way of the car.

1. If the engine slow fault light is on, it may be that the fuel pump is not pumping oil, and the car cannot be started, and it cannot be driven directly.

2. If the oxygen sensor fails, the car can still drive normally when getting off in this case, but it will lead to a deviation in the control of the engine's air-fuel ratio, which is more fuel-efficient than before.

3. False fault, ECU will warn (fault light) for some improper operation, in fact, there is no problem with the car.

Fault lamp analysis:

During the driving of the car, or the moment the car is ignited, the car engine fault light on the dashboard lights up, usually a red or yellow light, once it is on, it will not disappear automatically in most cases, and will disappear automatically in a few cases, which is the so-called engine fault light on.

The engine fault signal is sent by the ECU engine computer, and the ECU controls all the electronic equipment of the entire engine, such as electronic throttle, fuel injector, generator, fuel pump, etc., covering various systems such as air intake, exhaust, fuel, ignition, timing, etc.

Reasons why the engine failure light is on:

1. The combustion state is not good;

2. Engine knocking;

3. The fuel quality is not good;

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

5. The computer cannot obtain the engine data.

If the general engine fault light is on, it is possible that the state of combustion is not particularly good, and the state of the general engine is not good, which is the main reason for the amount of engine failure light. There is also an engine guarantee that will also cause the fault light to be on, such as the car is weak, and the engine noise is too loud, or there is a significant knocking sound. So it's still necessary to do some regular maintenance and repairs.

The engine fault light is not necessarily the engine failure, but more often some parameters exceed the standard value, such as exhaust emissions exceeding the standard, or for some reason the engine fires, etc.

Reasons why the engine failure light is on:

1. The combustion state is not good;

2. Engine knocking;

3. The fuel quality is not good;

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

5. The computer cannot obtain the engine data.

Can the car be driven when the fault light is on?

The engine fault light is on, it may be that the fuel pump does not pump oil, and the car cannot be started, and it cannot be driven directly; It is also possible that the oxygen sensor is faulty, and the car can still drive normally when getting off in this case, but it will cause the control of the air-fuel ratio of the engine to deviate, which is more fuel-efficient than before.

There is also a possibility that the fault light is on, that is, a false fault, and this possibility is relatively large, for example, you have just driven a family car in the mud to a high-speed off-road, or curious about what a plug is doing and pulled it out and plugged it in, ECU will warn you about this improper operation (fault light), in fact, there is no problem with the car, just eliminate the fault code.

The danger of the engine failure light on.

After the engine fault light is on, there are always some abnormal states, if not solved in time, it is usually accompanied by the following problems:

1. The quality of automobile exhaust gas deteriorates and pollutes the environment;

2. Increased fuel consumption of automobiles, waste of petroleum resources and RMB resources;

3. The temperature of the combustion chamber increases and the wear intensifies, which may lead to early damage to the engine;

4. The engine burns engine oil;

5. The engine noise increases, affecting the comfort of driving and riding.
