. Engine oil leakage failure: The reason for the engine oil leakage is that the piston ring, piston inner ring or other seals are damaged, resulting in vibration or internal friction caused by wear. The gasoline in the fuel tank cannot circulate normally, and the phenomenon of oil leakage occurs.

3. Common faults of automobiles Main faults: abnormal performance of automobiles Abnormal performance of automobilesThat is, the poor power and economy of the car, mainly manifested in the significantly low maximum driving speed of the car and the poor acceleration performance of the car; the large fuel consumption and large oil consumption of the car. The ride comfort of the car is poor, and the vibration and noise of the car are obviously increased.

What are the common faults of cars

1. Car faults are the phenomenon that cars cannot complete their functions, such as engine start-up difficulties, car failures, car oil leakage, lighting system failures, etc. There is something wrong with this car. Common faults include sudden changes in working conditions, abnormal sound, abnormal smell, abnormal smoke exhaust, abnormal temperature, abnormal appearance, abnormal fuel and lubricating oil consumption, and leakage.

2. There is something wrong with this car. Common faults include sudden changes in working conditions, abnormal sound, abnormal smell, abnormal smoke exhaust, abnormal temperature, abnormal appearance, abnormal fuel and lubricating oil consumption, and leakage.Common faults are often encountered in use.

3. Causes of car failure 1 Abnormal car performance Abnormal car performance is the poor power and economy of the car, mainly manifested in the obvious low maximum driving speed of the car and poor acceleration performance of the car; high fuel consumption and large oil consumption of cars. The ride comfort of the car is poor, and the vibration and noise of the car are obviously increased.

4. Car failure is the phenomenon that the car cannot complete its functions, such as engine difficulty in starting, not starting the car, car oil leakage, water leakage, lighting system failure, etc. There are faults in the car. Common faults are: sudden working conditions, abnormal sound, abnormal smell, abnormal smoke exhaust, abnormal temperature, abnormal appearance, abnormal fuel and lubricating oil consumption, and leakage.

5. Driving by carAbnormal sound is one of the most common fault phenomena. It may be a screw that we accidentally dropped somewhere, it may be caused by some loose or lack of lubrication, and some parts may be deformed or damaged. For this kind of fault, we first need to judge the approximate direction through the abnormal sound source, and then find the location according to the direction.

car fault light

1. The car fault light is a light used to indicate the fault of the car. It is generally divided into oil alarm light, water temperature alarm light, engine fault light, brake system fault light, steering assistant alarm light, door or front cover unclosed prompt light, tire pressure alarm light, ABS alarm light and battery alarm light.

2. Car fault light includes engine fault light, oil alarm light, water temperature alarm light, battery fault light, body stability system fault light, etc. 1 Engine fault light When the engine fault light is on, go to the 4S store or repair shop for overhaul in time 2 Oil alarm light When the oil alarm light is on, do not continue Continue to drive, find a safe.

3. Engine fault light Engine fault light is the most common fault light in the automobile electronic control system. When the engine control module detects some fault, it will send a signal to turn on the light.Common causes include oxygen sensor failure, ignition system failure, oil line system failure, exhaust system failure, etc.

4. There are six types of vehicle fault indicator light, oil alarm light, engine fault light, brake system fault light, tire pressure alarm light, water temperature alarm light, battery alarm light 1 oil alarm light, the shape of this fault light seems to be a teapot. If this fault light is on the dashboard, it means that the engine Insufficient amount of engine oil.

5. The common fault lights of cars are as follows: tire pressure warning lights. Yellow logo, an irregular circle without a seal, four small spikes below, and an exclamation mark inside. If this sign appears, it means that the tire pressure of the car tire is abnormal, and the tire should be checked in time.

What is the reason why the engine fault light is on

The reasons why the engine alarm light are on are as follows: sensor problems: sensors include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or signal interruption, the car's The ECU cannot accurately obtain the engine data, which will cause the engine fault light to turn on at this time.

The sensor is damaged, and the engine fault light will turn on when the contact is bad or the signal is interrupted. Poor engine maintenance is the most common reason for engine failure. Therefore, it is suggested that the car should be maintained on time and maintain good driving habits, otherwise it will increase the burden of engine operation.

If there is a problem with the air intake system, there will be poor combustion, and the engine fault light will turn on.

The reason why the engine fault light is on may be maintenance problems, oxygen sensor problems, and oil problems.

There are about three reasons why the engine fault light is on: false fault problem: the engine fault light is on, but it is still working, and even if it is detected, the problem cannot be found. This may be a fake fault problem. The engine fault light is on because of the garbled code generated by the car ECU during the calculation process.

The reason why the engine of the car dashboard is yellow. There are many types of fault lights on the dashboard of the car. Once these fault lights are on, the corresponding parts of the vehicle may fail or abnormal.

What are the common faults of cars?

Car failure is that the car has noThe phenomenon of completing its functions, such as engine start-up difficulty, car failure, car oil leakage and water leakage, lighting system failure, etc. There is something wrong with this car. Common faults include sudden changes in working conditions, abnormal sound, abnormal smell, abnormal smoke exhaust, abnormal temperature, abnormal appearance, abnormal fuel and lubricating oil consumption, and leakage.

Common faults and causes of cars are as follows: abnormal working conditions of cars. Some abnormal phenomena suddenly occur during car use, which should be prevented: the engine suddenly turns off while driving; the car does not brake when it needs to be braked; the car can't start in winter; it can't start after the engine is turned off; steering suddenly while driving However, it failed; what's more, there are flat tires and spontaneous combustion of cars.

There is something wrong with this car. Common faults include sudden changes in working conditions, abnormal sound, abnormal smell, abnormal smoke exhaust, abnormal temperature, abnormal appearance, abnormal fuel and lubricating oil consumption, and leakage.Common faults are often encountered in use.

Causes for automobile failure 1 Abnormal car performance Abnormal car performance is the poor power and economy of the car, mainly manifested in the significantly low maximum driving speed of the car and poor acceleration performance of the car; large fuel consumption and large oil consumption of the car. The ride comfort of the car is poor, and the vibration and noise of the car are obviously increased.

A collection of common faults in automobiles

Engine failures: including gasoline pump failures, ignition coil failures, cylinder head failures, etc. Battery failure: including insufficient battery charging, battery damage, vehicle circuit failure, etc. Cooling system failure: including water pump failure, water tank failure, radiator failure, etc.

"oil into water" and "water into oil" are two different faults."Oil into water" is a problem with the engine body itself, while "water into oil" is mostly caused by engine accessories, and the nature of the fault is different. Solution: You should go to the repair shop for replacement and repair in time.

. Engine oil leakage failure: The reason for the engine oil leakage is that the piston ring, piston inner ring or other seals are damaged, resulting in vibration or internal friction caused by wear. The gasoline in the fuel tank cannot circulate normally, and the phenomenon of oil leakage occurs.

This article will introduce the common faults of automobile engines and their repair methods to help readers better understand and solve these problems. The engine cannot be started. The engine cannot be started due to battery failure, ignition system failure, oil supply system failure and other reasons.

Common faults include sudden changes in working conditions, soundAbnormal sound, abnormal smell, abnormal smoke exhaust, abnormal temperature, abnormal appearance, abnormal fuel and lubricating oil consumption, leakage. Common faults are often encountered in use. When braking while driving, the car cannot slow down or stop; after one or more consecutive brakes, the brakes suddenly fail.
