What should I do if the automatic transmission car stalls during driving?

In this case, if there are no unexpected situations on the road, it can be restarted without stopping.

Method: Quickly push the gear lever into neutral gear (N), turn the ignition switch to the start (start) position, and then quickly pull the gear lever to the driving gear (D) after successful restart, and then you can drive normally. If the engine still fails to start after repeated attempts, the fault is serious, and it is time to stop the engine for maintenance.

Tips: This method must be familiar with the vehicle, if the gear lever is pushed directly into the reverse gear (R), it will cause greater damage to the transmission, and the ignition switch of some cars has the function of preventing secondary start, the key must be turned back to the closed position before restarting, but be careful not to lock the steering wheel, in addition, after the engine is turned off, the brake and steering power assist will also fail, at this time, more force is needed to control the vehicle.

Everyone is aware of all this, but in an emergency, it is inevitable to be in a hurry, so if you are a newbie, it is better to park your car on the side of the road first.

Let's talk about buying a car, using a car, maintaining a car, and repairing a car.

Here's why:

1. Generator failure.

The car generator can charge the battery, and the key is that after the car starts, almost all of the car's electricity is provided by the generator. It can be thought of this way, if the generator fails and no longer generates electricity, then the electricity of the whole car will be borne by the battery, and the battery does not have a generator to charge, the power will be used up quickly, and the ignition system will not work at that time, that is to say, once the generator does not generate electricity, the car will soon turn off.

Therefore, the generator failure is one of the major reasons for the automatic transmission car to turn off while driving. In fact, under normal circumstances, generators rarely fail, and most of the faults are caused by the aging and fracture of the generator belt.

The rubber parts on the car will age, including the generator belt, which is easy to break when aging, so the best way to prevent the generator from failing is to replace the generator belt preventively.

Second, the ignition system is faulty.

For the automobile ignition system, the spark plug, ignition coil and cylinder wire with the greatest probability of problems are the spark plugs, and the spark plugs are the most. If the spark plug or ignition coil of more than 2 cylinders fails, the car may stall while driving, but compared with the spark plug, the ignition coil problem is easier for us to ignore.

Spark plugs are wearing parts, have a service life, belong to one of the maintenance items, and naturally need to be replaced regularly, and the ignition coil is actually a wearing part, which also has a service life. However, the service life of the ignition coil is generally longer than that of the spark plug, generally reaching more than 100,000 kilometers.

3. Oil circuit failure.

The oil circuit fault is well understood, and the low fuel supply pressure will cause the automatic transmission car to suffocate and stall while driving. Oil circuit failures include oil circuit blockage, fuel pump failure and high-pressure oil pump failure (direct injection engine generally has 2 oil pumps, one of which is a high-pressure oil pump). The main places where the oil circuit is easy to block are the fuel pump filter, gasoline filter and fuel injector, no matter which link in the oil circuit has a problem, it may cause the car to stall due to poor fuel supply.

In addition to the failure of the fuel pump, the quality of the gasoline and the carbon deposition of the added gasoline play a special role in the working condition of the oil circuit, and the low oil pressure affects the atomization of the fuel injector, and the car is not only easy to stall, but even directly unable to start.

Fourth, the air intake failure.

Needless to say, if the intake fails and does not provide enough air to the engine to burn, it is understandable that there is a stall, and the most likely problem with the engine intake is in the throttle and idle valve.

Among them, the idle valve has serious carbon deposits, which will cause the engine to idle unstable.

The throttle valve seriously affects the opening angle due to carbon deposition, which may cause the automatic transmission car to stall while driving, and if the throttle carbon deposition is serious, it is still very necessary to clean.

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.

Hello, check the gasoline pressure and spark plug [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello answer, I have seen your question and am sorting out the answer, please wait a while Oh Dear! 1. Hold the steering wheel steady, quickly push the gear into neutral (N), turn on the double flashing lights, and warn the vehicles behind. Remember not to push too hard when shifting gears, push the gear lever directly into P or R gear, pushing into R gear will cause more damage to the transmission.

2. Turn the ignition switch to the start position, and after the restart is successful, quickly pull the gear lever to D gear and enter normal driving.

3. After many attempts, the engine still cannot start, and the old drivers will decisively stop for maintenance. If you are a novice driver, you should pull over for safety and then start the vehicle normally.

Question, thanks for the suggestion.

First of all, after the ignition is turned off, do not hit the steering wheel and step on the brakes many times, because the direction and braking need to be assisted, and there are generally only two opportunities to brake after the ignition, if there is no special situation in front, you can restart without stopping.

Then, quickly push the gear lever into neutral gear (N), the ignition switch to the start (start) position, after the restart is successful, and then quickly pull the gear lever to the D lever, you can drive normally. If the engine still fails to start after several attempts, the fault is more serious, and it should be stopped for maintenance.

Finally, it is recommended that car owners should park their car safely on the side of the road first, and then restart the vehicle according to the method described above.

Let's talk about buying a car, using a car, maintaining a car, and repairing a car.

Don't panic when you suddenly turn off the engine, the steering wheel and brakes will become heavy. But it's not impossible.

Hold the steering wheel tightly and apply the brakes firmly. Find a safe place to stop.

If there is no vehicle in front of you, keep the vehicle steady. Restart the engine again.

Cars equipped with automatic transmissions do not have clutches, and under normal circumstances, the engine will not stall due to improper operation by the driver. However, due to the poor condition of the vehicle's engine, some occasional mechanical or electronic failures, the engine may be accidentally stalled in the middle of the process.

In this case, don't panic at first, quickly observe the surrounding traffic conditions, and if the surrounding traffic conditions and conditions allow, you can try to restart the engine without stopping.

Because automatic transmission cars have a neutral safety switch, the vehicle can only be started in P and N gears. Because the vehicle is still coasting by inertia, you must not push the gear lever directly into P gear. But you can shift into N gear first, and the way to restart the engine is:

Quickly push the gear lever into neutral gear, generally you don't need to step on the brake to change the gear lever from D gear to N gear, turn the ignition switch to the starting position and start again, and then quickly pull the gear lever to D gear after success, and you can drive normally. If the engine still does not start after several attempts, the fault is serious and you should pull over.

It is dangerous to restart an automatic transmission vehicle in the middle of the process after it has been turned off. It is required to be familiar with the operation of the vehicle, and if the gear lever is pushed directly into reverse gear (R) if the force is too high, it will cause great damage to the transmission. Some cars have a ignition switch to prevent secondary starting, and you must turn back to the off position before you can start again, but be careful not to lock the steering wheel.

In addition, when the engine stalls, the brakes and steering power fail, and more force is required to control the vehicle.

If you're a newbie, it's best to pull over to the side of the road and ask for help or rescue. Remember: at no time can vehicles equipped with automatic transmissions be started with anti-tow.

This depends on which alarm light is shown by your trip computer, and there are many reasons!

Go to the repair shop and check the computer to see if there are any fault codes.

How about the battery, the throttle is dirty or not.

Hello, the throttle is dirty, clean it.

There are four main causes of vehicle stalling: oil circuit, valve, circuit, and sensor failure.

1. When the engine is working normally, the oil pump will pump the fuel out of the fuel tank, enter the piping through the filter, and then spray it out from the fuel injector to form an oil-gas mixture. In this process, fuel pumps and injectors are the most likely to fail, followed by clogged filters and oil circuits. Please focus on these two locations.

If necessary, the oil circuit can be cleaned. In order to reduce the occurrence of such situations, it is necessary to add gasoline that meets the label at a regular gas station when refueling, and at the same time add fuel in time, and try not to let the amount of fuel fall below the red line.

2. Throttle blockage. The throttle valve is undoubtedly the most important component, but it is also the most problematic component. In general, maintenance personnel will consider cleaning the throttle.

However, if the flameout problem cannot be completely solved by frequent cleaning of the throttle, it is generally a fault. In addition, check the vacuum pump to see if the air intake is normal.

3. The ignition of the spark plug is abnormal. Replace the spark plug according to the service life, when the gasoline engine compresses close to the top dead center, the combustible mixture is ignited by the spark plug, so when the spark plug failure "strikes", it will naturally cause the vehicle to stall. Normally, it is completely solved by replacing the spark plug, and when it is inconvenient to replace, it can also be temporarily solved by cleaning the electrode and adjusting the emergency measures of the electrode length.

In addition, insufficient battery voltage, leakage, ignition coil failure, and line failure will lead to poor ignition or flameout.

4. Sensor failure leads to ECU protective oil cut-off. Check whether the sensors and actuators are working properly, the main sensors are throttle position sensor, oxygen sensor, crankshaft position sensor, etc., you have replaced the crankshaft position sensor, and also detect whether the oxygen sensor is poisoned. Therefore, it is recommended that the landlord go to the 4S store to do a comprehensive test, focusing on the spark plug, fuel pump, oxygen sensor, and finally computer matching, I hope it can help you.

There are generally three reasons why automatic transmission cars suddenly stall when reversing, one is circuit failure. This possibility is that the power is cut off due to low voltage during driving. At this time, you can mainly check the ignition and starter switches, as well as the fuse box.

A short circuit in a low-voltage line causes a flameout, in which case it is an intermittent flameout. Check the low-voltage line, one is a device failure. This problem is generally the ignition coil, capacitive electric, electronic ignition module.

It starts at the beginning, turns off after a while, and then starts again and turns off again. There is also the failure of the oil circuit. The gasoline pump was damaged, the oil line was ruptured, the carburetor inlet was clogged, and the fuel tank ran out of oil.

But in this case the car can be restarted, but it is difficult.

Hello! Quickly turn on the quad flash switch! I get close to the right side of the road by inertia!

Just put the gear in neutral position to start the car! The possible reason why the automatic gear stalls while driving: there is a throttle idle motor failure!

The oil pump is faulty! Engine electrical failure! It is recommended that you check if the throttle idle motor needs to be cleaned!
