What is the reason why the engine fault light is on

1, so 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, thus causing the fault light Bright.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.

2. 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 owner that it needs 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.

3. Mainly because the oxygen sensor, water temperature sensor, crankshaft position sensor and air flow sensor are damaged, or when the contact is bad, the driving computer of the car cannot obtain the relevant data of the engine, resulting in the engine fault light to light up.

The car engine fault light is on. What should I do?

As soon as 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.

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

The reasons and solutions for the engine fault light are as follows: the oxygen sensor of the vehicle is damaged; the owner needs to replace or repair the oxygen sensor in time. Poor fuel quality; car owners need to improve fuel quality and replace higher quality fuel. The inside of the engine cylinder is not clean and there is carbon accumulation; at this time, the carbon accumulation should be cleaned and the engine should be cleaned in time.

What is the reason why the engine light is on for the car fault code?

Vehicle engine emission system failure, this failure is the main and one of the most common reasons for the vehicle engine failure light. If this failure occurs, most of the reasons for the carbon accumulation of the vehicle engine or the problem of fuel quality.

The specific 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 sensors are damaged, poor contact or signal interruption, the ECU of the car cannot accurately obtain the engine data. At this time It will cause the engine fault light to light up.

Hello, the car engine fault light is on for the following reasons 1 engine cylinderThe interior is not clean and there is carbon accumulation. After a certain period of use, some carbon accumulation must accumulate inside the engine. These carbon accumulations themselves will cause changes in the engine design parameters. At the same time, their properties are unstable and accumulate heat, which will lead to the engine.
