What is the reason why the Nissan Xuanyi engine fault light is on? The reason why the Xuanyi engine fault light is on

1. The specific reasons and solutions of the Nissan Xuanyi engine fault light: sensor damage: poor contact or signal interruption will cause the engine fault light to light up. Solution: Change a sensor. Oil quality problem: Poor oil quality will lead to insufficient combustion of the mixed gas in the cylinder, resulting in lighting.Solution: Use high-quality gasoline.

2. Due to the abnormal temperature error of the sensor, the engine fault light may light up. The main reasons for the fault light of Xuanyi engine are the following three points: sensors: including water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc.

3. There are many reasons why the fault light of Xuanyi engine is on. One of them is that the engine system is not working poorly due to the exhaust gas emission that does not meet the standard, resulting in the fault light. In addition, the gearbox system failure of some vehicles is also indicated by the engine fault light, such as internal gearbox failure, slipping or high temperature.

4. Pulled and dragged by other vehicles. Borrow the power supply of other vehicles to start. Use the downhill to start.

5. The specific situation analysis is as follows;Sensor problem; 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, which will cause the engine failure light to turn on.

6. The quality of automobile fuel is not qualified. If the engine fault light on the dashboard of the car lights up shortly after the vehicle is refueled, then it is generally due to the wrong oil addition, poor quality, and non-standard, resulting in insufficient combustion of oil-gas mixture when the engine is working.

5. 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 data of the engine. At this time It will cause the engine fault light to light up.

6. The quality of automobile fuel is not qualified. If the vehicle is refueled shortly after it is refueled, the engine fault light on the dashboard of the car is on. Well, this is generally because the oil is added incorrectly, the quality is poor, and it does not meet the standard, resulting in insufficient combustion of the oil-gas mixture when the engine is working.

What to do if Xuanyi engine fault light is on

1. Replace ternary catalytic conversion Instrument, etc.Fault lights caused by poor operation of the engine system, such as accelerator pedal sensor, throttle position sensor, air flow meter, crankshaft position sensor, etc., or poor line contact, will cause the engine fault light to turn on. It should be repaired or replaced according to the specific situation.

2. The solution includes replacing the ternary catalytic converter, etc. Fault lights caused by poor operation of the engine system: such as failure of throttle pedal sensor, throttle position sensor, air flow meter, crankshaft position sensor, etc., or poor line contact and other problems will also cause the engine fault light to light up.

3. Xuanyi engine fault light is on. First, check the water temperature gauge and oil pressure alarm light. If the water temperature gauge and oil pressure alarm light do not alarm, control the speed of the vehicle and drive to the repair station in time for maintenance.If the water temperature is too high or the oil pressure alarm light is on, or the vehicle is obviously faulty, you should stop and wait for rescue.

4. When the Xuanyi engine fault light is on, you need to check the water temperature gauge and the oil pressure alarm light. If the water temperature gauge and the oil pressure alarm light do not alarm, control the speed of the vehicle and drive to the 4s store or repair shop in time for testing and maintenance.
