If the engine temperature is too high, the temperature of the entering the air will inevitably be very high. The oxygen content of high-temperature air is very low, which is not conducive to sufficient Burn. And if the temperature is too high, it will cause its compression and spontaneous combustion. Solution: Don't forget to add coolant at ordinary times, put the car in a cool place, and check whether the thermoster is normal.
The problem of oil, it is necessary to choose the appropriate oil and gasoline according to the characteristics of the engine. There is a problem with the sensor of the vehicle, causing the fault light to turn on. Problems with spark plugs or lines will lead to insufficient combustion of the engine mixture. Maintenance problems, or too much carbon accumulation will also cause insufficient combustion.
The reasons why the car engine fault light is on are as follows: ignition system failure;Start-up system failure; fuel injection system failure; intake system failure; ECU failure; oil problem; oil lubrication system failure.
1. Sensor failure: The sensor on the vehicle may fail, such as air flow sensor, oxygen sensor, throttle position Sensors, etc., these sensors may send wrong signals to the vehicle computer, causing the engine indicator light to light up.
2. There are many reasons, and the common ones are as follows: oxygen sensor failure. If the oxygen sensor is damaged or the sensor plug is damaged or loose, it will cause the mixed gas to be too thin or too thick, causing the fault light to turn on. The quality of gasoline is poor and does not meet the standard.
3. What is the reason for the yellow light of the engine fault light? The yellow light of the engine fault light usually indicates that there is some kind of fault or abnormality in the engine system. My husband and I went out for a self-driving trip. On the middle of the road, we encountered a yellow light on the engine fault light. We mainly had a problem with the crankshaft transmission system, which was an engine mechanical failure.
4. The yellow light of the engine fault light is mainly as follows: the throttle valve is stolen, resulting in the mixed gas. The engine accumulates too much carbon, resulting in unqualified exhaust emissions. The reason for excessive carbon accumulation may be that the quality of the frequently used oil is not very good, the maintenance is not done on time, or it is also related to the usual driving habits.
5. If the engine turns yellow, it means that there is something wrong with the car engine. This engineThere are many reasons for the fault light, such as poor quality of gasoline, oxygen sensor failure, air flow sensor failure, spark plug carbonization, engine explosion, water temperature sensor damage, etc. Sensor problem.

I: The common reasons are the misalignation of the engine sensor signal, mainly including: lack of maintenance, long-term non-cleaning of the throttle valve, long-term non-cleaning of the engine carbon accumulation, and the accumulation of carbon will adsorb part of the fuel vapor. For example, the throttlue position transmissionThe dirty blockage of the sensor leads to poor operation of the engine, accompanied by insufficient power, idling jitter, engine fault light on, etc.
3. [Pacific Automobile Network] The reasons why the engine light is on: poor combustion of the mixed gas of the engine; abnormal fuel supply pressure; wear of the spark plug pole gap; failure of the ignition coil; aging of the rubber parts of the starting bracket or gearbox bracket; blockage of the throttle valve. Oxygen sensor failure.
4. It is mainly because the oxygen sensor, water temperature sensor, crankshaft position sensor and air flow sensor are damaged, or when the contact is poor, the driving computer of the car cannot obtain the relevant data of the engine, resulting in the engine fault light.
5. The reasons why the engine alarm light is on are 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 and have poor contact or the signal is interrupted, the ECU of the car cannot accurately obtain the engine data, which will cause the engine failure light to turn on.
6. What is the reason why the engine fault light is on? It may be caused by the failure of the sensor, electronic system or exhaust system. When these key parts are damaged, the engine cannot accurately judge the current situation of the vehicle, causing the fault light to turn on. The quality of gasoline may also cause the engine fault light to light up.
There are problems with the sensor mainly oxygen sensor, water temperature sensor,When the crankshaft position sensor and air flow sensor are damaged, or the contact is poor, the driving computer of the car cannot obtain the relevant data of the engine, resulting in the engine fault light.
Therefore, if the oxygen sensor is damaged or the sensor plug is damaged or loose, the mixture will be too thin or too thick, resulting in a fault light. In fact, the oxygen sensor is a fairly durable component. As long as the fuel quality passes, it can be used for 3 years or more.
Generally, when the fault light is on, it means that there is a problem with the parameters of the engine. The driving computer can no longer solve it by adjusting the fuel injection and other measures. This fault light will be turned on to remind the car owner to deal with it as soon as possible. There are three main reasons why the engine fault light is on. The first is that the combustion state in the cylinder is not good, or the sensor is falsely reported.
There are 7 common reasons why the engine fault light is on: Sensor: The sensors mentioned here include water temperature, crankshaft position, empty air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, have poor contact, or the signal is interrupted, and the ECU of the car cannot accurately obtain the engine data, it will cause the engine failure light to light up.
I: The common reasons are that the engine sensor signal is not accurate, mainly: lack of maintenance, long-term non-cleaning of the throttle valve, long-term failure to clean the engine carbon accumulation, and the accumulation of carbon accumulation will adsorb part of the fuel vapor.
Hello, the fault light of the car engine is on for the following reasons: 1 The inside of the engine cylinder is not clean and there is carbon accumulation. After a certain period of use, some carbon accumulation must be accumulated inside the engine. TheseCarbon accumulation itself will cause changes in the engine design parameters, and its nature is unstable to accumulate heat, which will lead to the engine.
