Automobile engine fault light on

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

Maintenance problem; Poor engine maintenance is the most common cause of engine failure.

The reason why the engine fault light is on is: sensor problem: when the sensor is damaged, the contact is poor or the signal is interrupted, the ECU of the car cannot accurately obtain the engine data, which will cause the engine fault light to light up; maintenance problem: the owner's failure to maintain on schedule will increase the burden of engine operation. It can only be reminded by the fault light.

The reason why the car engine fault light is on

1. The specific situation analysis is as follows; sensor problems; the sensor mentioned here Including water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, the contact is poor or the signal is interrupted, the ECU of the car cannot accurately obtain the engine data, which will cause the engine fault light to turn on.

2. Problems with the sensor are mainly caused by damage to the oxygen sensor, water temperature sensor, crankshaft position sensor and air flow sensor, or when the contact is poor, the driving computer of the car cannot obtain the relevant data of the engine, resulting in the engine failure light to light up.

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

4. The reasons why the engine fault sign light is as follows: poor quality of gasoline will cause the mixed gas to burn insufficiently in the cylinder, causing the fault light to turn on, and it is also easy to produce carbon accumulation. The presence of carbon accumulation at the top of the intake airway and piston will lead to poor atomization, resulting in insufficient combustion and the fault light.

5. There are about three original engine fault lights.Cause: Fake fault problem: The engine fault light is on, but it is still working. 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.

6. In fact, the reasons why the fault light of the car engine is on include sensor problems, maintenance problems, oil quality problems, poor combustion of mixed gas, air intake problems, etc. These problems may cause the fault light of the car engine to turn on.

What's wrong with the car showing engine failure

1. Explain the reasons for the failure of the car engine: failure to repair on schedule; deterioration of the oil; blockage of the empty air filter; dirty intake pipe; more sludge in the crankcase; fuel System maintenance; the water tank is rusty and scaled.The reasons for automobile engine failure are as follows: unplanned maintenance: vehicle failures caused by poor engine maintenance account for about 50% of the total failures.

2. The specific analysis is as follows; sensor problems; the sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or the signal is interrupted, the ECU of the car cannot accurately obtain the engine data. At this time It will cause the engine fault light to light up.

3. The reasons for the failure of the car display engine are as follows: non-maintenance on schedule; deterioration of the oil; blockage of the air filter; dirty intake pipe; a lot of sludge in the crankcase; maintenance of the fuel system; rust and scale of the water tank. The specific causes of automobile engine failure are as follows: Failure to maintain on schedule: The failure caused by poor engine maintenance of the vehicle accounts for about 50% of the total failure.

4. When the car is only connected to the power supply and has not been ignited, it is normal for the engine fault light to be on. If the vehicle is not faulty, it will be extinguished after the ignition. If the vehicle really breaks down, it will not go out after it catches fire. That is to say, check whether the fault light of the vehicle is on, and then see it after it is on fire.

5. This article will introduce the common faults of automobile engines and their maintenance 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.

6. Common faults of automobile engines Fault 1: Engine overheating fault. Due to the special structure of the car engine, it is easy to have excessive coolant temperature during operation.Once the coolant temperature exceeds the normal value, the engine cannot dissipate heat normally, which will cause the engine to overheat and affect the normal operation of the engine. Fault 2: The smell of the engine compartment.

What is the reason why the engine fault light is on

The sensor is damaged, and the engine fault light will turn on when the contact is poor 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.

The reasons why the engine alarm light is on are as follows: sensor problems: sensors include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensorsWhen the device is damaged, the contact is poor or the signal is interrupted, the ECU of the car cannot accurately obtain the data of the engine, which will cause the engine failure light to turn on.

There are many reasons: vehicle engine ignition system failure. The engine start system of the vehicle fails. Fault of the engine fuel injection system. The engine intake and exhaust system is faulty. Engine ECU failure, the above problems will cause the engine failure light to light up.

What to do if the car shows engine failure

1. Once the fault indicator light turns on, stop and check as soon as possible. Drive the car to the roadside or other safe places without affecting other vehicles and turn off the engine. Open the hood and check the engine for odor, smoke or other abnormalities.

2. The solution to the car's display engine failure is: check the status of the car engine in time; check the status of the car's sensors, air flow sensors and spark plug parts; check whether the car has bursts; check whether the ignition coil is faulty; and the engine has serious carbon.

3. The engine fault light of the car is on. It is recommended to go to the repair shop for inspection.

4. However, in the process of using the car, the engine often fails, which affects the performance of the car and increases the economic pressure on the driver. This article will introduce the common faults of automobile engines and their maintenance methods to help readers better understand and solve these problems.

Common faults of automobile enginesAnd the solution

1. Eliminate the special smell generated by the engine. During the use of the vehicle, if you find a pungent smell or burning smell in the engine compartment, you should stop immediately, check whether the lines around the engine have been softened or charred, and repair the charred or short-circuited lines in time to avoid more A major safety accident.

2. Gasket aging: After long-term use, the gasket of the engine (such as cylinder head pad, valve cover pad, etc.) is easy to age and crack, resulting in oil leakage. At this time, the corresponding gasket needs to be replaced.

3. "oil into water" and "water into oil" are two faults of different nature. "Oil into water" is a problem with the engine 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.

4. Solutions to common engine faults Method 1: Monitor the overheating of the engine in time. When the coolant temperature is abnormal, the dashboard that will be reported to the car should be stopped to check whether the coolant is leaking.

5. The common faults of automobile engines are summarized as follows: 1 engine cannot start; 2 engine stall fault; 3 engine idle failure; 4 mixed gas thin fault; 5 acceleration failure 1 engine cannot start (1) fault phenomenon: opening point Fire switch, turn the ignition switch to the starting position, and the engine will not start.

6. Common engine faults and solutions: faults. ( 1) Fault phenomenon: Turn on the ignition switch, turn the ignition switch to the start position, and the engine cannot start.
