What to do if the automatic transmission car suddenly turns off

Reasons for stalling: 1. Automatic transmission models: automatic transmission models will not easily stall, while manual transmission models may often stall due to low driving level.

However, it is not excluded that automatic transmission cars will not stall, and the main reason is the use of low-quality fuel (many gas stations sell impure oil in order to make huge profits), resulting in carbon accumulation in the engine.

If the idle speed is unstable and the ignition is turned off, it may be caused by too much carbon deposit in the vehicle, and you can go to the repair shop to clean up the carbon deposit to see if it can be improved.

Hello, if this automatic transmission car suddenly turns off, it is usually because of the lack of gas, or the engine failure.

What should I do if the car suddenly stops? Automatic cars should do this.

Reasons for the sudden stalling of the car while driving:

1. Circuit fault;

2. Flameout caused by short circuit of low-voltage line: intermittent flameout; 3. Device failure: it can start at first, turn off after a while, and then start again, and then turn off again;

4. Oil circuit failure; The gasoline pump was damaged, the oil line was ruptured, the carburetor inlet was clogged, and the fuel tank ran out of oil.

5. There is a problem with the ignition system and the explosion-proof system for engine overheating.

When it is found that after the ignition is turned off, according to the road conditions at the time, if there is no emergency, you can slowly step on the brakes to prevent the tail light, after the speed is reduced, slowly play the direction, drive to the roadside lane, pay attention, the brake should be stepped on all the time, the power from small to large, do not step on it and then loosen, and then go to the pedal, which will lead to the only remaining vacuum is also consumed, and then step on it can not be stepped on, park the car on the side of the road, turn on the four flashing lights, place the tripod, and hit the ** rescue trailer. Hope!

Hold the steering wheel with your hand to stabilize the direction (because there is no power assist, so you must stabilize it hard), press the brake with your right foot to reduce the speed as much as possible, and then quickly hit the AT gear to N gear, (Note: The re-ignition must be in N gear during the march, not D r P and other gears, otherwise, the car will either not ignite, or the car gearbox will be damaged), and then set the key back one notch, and then re-ignite, and then restore the AT gear to D gear normal driving.

The main reasons for the general car stalling:

1. Use low-quality fuel. Once the automatic car stalls, the main reason is the use of inferior (not up to standard) fuel, which in turn causes the engine to depot and stall.

2. Engine computer failure. From the point of view of kilometers, after using the car for a long time, the possibility of engine computer failure will be relatively large, once the engine computer fails, it will cause the car to stall, which is a problem of control. Just like the human brain, when there is a malfunction, the body "goes out".

3. The driving skills are not proficient enough. The driver's unskilled driving skills and improper operation will also cause the car to stall.

4. Multiple cylinder failures at the same time. It is possible that due to the failure of the spark plug or the high-pressure bag, one or more cylinders will not ignite, resulting in a flameout. However, only the failure of multiple cylinders at the same time and non-ignition can cause flameout, so there is such a possibility, but the probability is not large.

5. The engine itself fails. Damage to the engine idle motor or the wiring of the idle motor, or a problem with the idle control module in the engine's electronic control unit (ECU). The possibility of the engine itself failing is extremely high among the many reasons why a car stalls.

6. Oil pump failure. The stuck oil pump or the failure of the oil pump itself will cause a sudden lack of oil supply, and no oil supply will easily cause the car to stall.

1. The automatic transmission model will not easily stall, while the manual transmission model may often stall due to the low driving level. However, it is not excluded that automatic transmission cars will not stall, and the main reason is that the engine stalls due to carbon accumulation due to the use of inferior fuel (many gas stations sell impure oil for profiteering).

2. In addition, the reason for the stalling of the new car (automatic transmission) is mainly caused by the lack of skillful driving skills, and another possibility is the problem of the car engine or the oil circuit, but for the new car, the problem of the engine itself is less likely, and most of the reason is the problem of the oil circuit.

3. Finally, for old models, the reason for the stalling is not enough driving skills, that is, the use of substandard oil to make the engine collect carbon and other causes of stalling. Hope it helps.

There are many reasons why the engine stalls:

1. Vehicle battery problem: This problem is the most common, due to the expiration of the battery service life, the battery capacity and output voltage are reduced, which will directly lead to abnormal starter start, too low voltage, and the engine spark plug can not spark and other problems, when the problem is serious, the engine is turned off, and it is difficult to start, solution: replace the battery.

2. Vehicle high-voltage line failure: After the problem in 1 is discharged, priority should be given to checking whether the high-voltage line has aging, falling off, short circuit and open circuit problems.

3. The oil supply circuit of the engine is blocked, and the oil supply is abnormal, resulting in the interruption of the engine stroke, or the Mars plug in the cylinder is seriously dedeposited or ablated, resulting in unstable sparks and difficulty in starting the engine, and the engine is abnormally stalled when the throttle changes. Solution: Do a good job in the cleaning and maintenance of the engine oil circuit (including the oil supply oil circuit and lubricating oil circuit), check and replace the spark plug in time, and if necessary, do a cylinder carbon removal maintenance.

4. Normal phenomenon: At present, many medium and high-end models on the market, such as Cayenne BMW X series, Audi Q series some models have an advanced engine fuel-saving technology, that is, in the process of short-term parking, as long as the neutral gear is hung and the vehicle is stationary for a few seconds, the on-board computer will think that the vehicle is in the parking state in the section, at this time, the on-board computer will temporarily turn off the engine to reduce fuel consumption and emissions in the state of traffic lights, and the vehicle will automatically start and enter the driving state when the car is hung into D gear.

Reasons for the stalling of the automatic transmission car in driving: 1. Generator failure: the electricity of all the electrical equipment of the automatic transmission car comes from the battery, and the electricity of the battery comes from the generator. 2. Ignition system failure:

The ignition system is easy to damage the spark plug, followed by the ignition coil and cylinder wire, if the spark plug or ignition coil of more than two cylinders fails, the car will turn off; 3. Oil circuit failure: If the oil pressure is low, it will cause the car to stall, and the oil circuit failure is manifested in the oil circuit blockage, fuel pump failure and oil pressure pump failure, and the area that is easy to be blocked has fuel pump filter, gasoline filter and fuel injector.

The most common reason for the stalling of automatic cars is the lack of fuel, that is, gasoline. The second is the lack of engine oil, and then the lack of antifreeze. And then there is.

The engine is either an electrical or mechanical fault. And there is. Automatic transmission cars have manual automatic integration.

Then there's the mismatch between gear and rpm. Or the throttle didn't make a timely color. Cause the calf to pull the cart.

Exhausted.

If the automatic transmission car turns off, it can only mean that the engine is short of oil, or the circuit is faulty, causing the engine to not work, and it will turn off.

In the case of a vacuum-assisted braking system, it is possible that the vacuum tube booster is faulty. It is best to go to the 4S store and use a computer to diagnose the cause of the failure.

Well, there must be a reason, hey, because of the automatic writing work. Generally, it is not appropriate to bring books, and it is not appropriate not to pick. It is possible to make an appointment with the relevant place, or where the circuit is not good, or it may also turn off the engine.

Hello, after the engine fails and turns off, it must be a fault in the car, it is best not to, repeatedly ignite the drive, drive the car directly to the repair shop, and ask them to test the fault code for you with the computer, you will know what the fault is, and it is better to eliminate it as soon as possible

The reasons for the sudden stalling of the car are:

1. Driving skills are not skilled;

2. The oil used is unqualified;

3. The oil circuit is not smooth;

4. The engine idle speed is too low;

5. Lubrication or circuit problems;

6. Low pressure; 7. Device failure;

8. Oil circuit failure.

Flameout troubleshooting method:

1. For novices, turning off halfway is not a new topic, and the main elimination method is to improve their driving skills after rapid running-in.

2. Use high-standard, high-quality and qualified fuel.

3. Clean the oil circuit thoroughly, including fuel injectors, throttles, fuel tanks, etc. It may be that the quality of the oil you add is not up to par, there is too much grease, the oil path is blocked, and the oil supply is not smooth.

4. The main reason for the failure of the car to stall in the idle state is due to too much dust in the air, and there is a lot of dirt deposited at the valve core of the idle motor and the throttle seat when the engine is running. The solution to this problem is simple: just clean the idle motor.

5. Long-term parking of the car is not used. In fact, it is important not to park it for a long time. In case of a long parking time, you should do a thorough maintenance before re-use, change the oil, filter, etc., and check the fuel, electrical circuit, etc. as appropriate.

It is possible that your vehicle is due to lubrication or electrical problems due to prolonged parking.

6. If the ignition is out due to low-voltage power failure, you can mainly check the ignition and starter switches and fuse boxes at this time.

7. The sudden shutdown of the car while driving may be a device failure, and the problem is generally the ignition coil, capacitance electric, and electronic ignition module. It starts at the beginning, turns off after a while, and then starts again and turns off again.

8. The sudden shutdown of the car while driving may be a fault of the oil circuit, the gasoline pump is damaged, the oil pipe is broken, the oil inlet of the carburetor is blocked, and the fuel tank is out of oil. But in this case the car can be restarted, but it is difficult. Ignition system, engine overheating, explosion-proof system, if there is a problem, it will turn off. Hope!

Hello, after the engine fails and turns off, it must be a fault in the car, it is best not to, repeatedly ignite the drive, drive the car directly to the repair shop, and ask them to test the fault code for you with the computer, you will know what the fault is, and it is better to eliminate it as soon as possible

Question: The repair shop said that the crankshaft sensor was broken.

1.Flameout caused by carbon deposits: carbon deposits exist in throttles, spark plugs, etc.;

3.Ignition system failure: carbon deposition in the spark plug and insufficient ignition voltage;

4.Faulty power supply: If the battery loses a lot of power, it can make it difficult to start the engine, or even not start.

5.The engine control system is abnormal.

Dear, damage to the crankshaft sensor will lead to no oil supply and no start.

If you suddenly turn off the ignition, it should also be accompanied by difficulty starting. Question: Yes, this is the car.

The sudden shutdown of the car license involves a wide range, and the probability of the problem of the oil pump is relatively large.

Models with manual transmissions may often stall due to their low driving skills. However, this is only an occasional occurrence in automatic transmissions, and the main reason for this is that the engine stalls due to carbon build-up caused by the use of low-quality fuel.

In addition, the reason for the stalling of the new car is mainly caused by the lack of skillful driving skills, and another possibility is the problem of the car engine or the oil circuit, but for the new car, the problem of the engine itself is less likely, so it is mainly the problem of the oil circuit. For old cars, the reason for stalling is not only the lack of driving skills, but also the stalling caused by the use of substandard oil to collect carbon from the engine.

Get into the habit of starting a cold car and warming it up.

The specific steps are: get in the car, rotate the key and turn on the power, and then ignite it in about 5-10 seconds! After ignition, the car warms up and starts in about 30 seconds! At this time, you will no longer feel the body tremble, and there will be no more stalling problems!

There are many reasons for the automatic transmission car to turn off, and the specific needs to be combined to judge, generally there are the following reasons, the oil road is not passable, the oil supply is not continuous, the driver turns off the car, and the car runs out of gas

Here's why:1. Circuit fault; This possibility is that during the driving process, due to the low voltage of the calendar, the hungry bird power was cut off and the engine was turned off. At this time, you can mainly check the ignition and starter switches, as well as the fuse box.

2. Short circuit of low-voltage line. In this case, check the low-voltage wiring of the car.

3. Device failure. Generally, it is an ignition coil, a capacitive electrical unit, and an electronic ignition module. The performance is that it starts at first, turns off after a while, and then starts again and turns off again.

4. Oil circuit failure; The gasoline pump was damaged, the oil pipe was ruptured, the vaporizer inlet was blocked, and the fuel tank was rotten.

5. Ignition system, engine overheating and detonation system will turn off if there is a problem.

The cause of flameout may be the use of low-quality fuel and carbon deposits in the engine, or it may be circuit failure, equipment failure, oil circuit failure, etc. If the vehicle is turned off, you should keep the grinding section empty, press the brake pedal to stop, turn on the double flashing lights of the vehicle, try to put the blind position into P gear and then re-ignite and start the vehicle.

Actually, the original of the automatic transmission car suddenly turned off. In fact, most of the reasons for the sudden shutdown of automatic transmission cars are caused by the problems of Lu Lao's circuit, because empty orange automatic transmission cars generally do not exist and let him stop when they are overloaded. The general fighting group is caused by poor circuit contact or damaged computer board.
