What is the reason why the Qijun engine fault light is on

1. The specific situation 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, which will cause the engine fault light to turn on.

2. The reasons for the failure light of the Nissan Qijun engine are as follows: the exhaust emission does not meet the standard. Specific problems include poor fuel, ternary catalyst failure, excessive carbon accumulation in the intake pipe, fuel injector blockage, oxygen sensor failure and occasional engine shutdown, etc. Among them, poor oil quality is the reason why the engine fault light is the most lit.

3. [Pacific Automobile Network] There are 4 main reasons why the fault light of Qijun engine is on: 1. The combustion state is not good, 2, the use of poor quality fuel, 3, there is carbon accumulation in the engine cylinder, 4, the engine explosion. The engine failure signal is sent by the car engine computer.

4. The reason why the engine fault light is on Poor combustion state: The poor combustion state of the engine is the main reason why the engine fault light is on.

The engine fault light of Qijun dashboard is always on, and the automatic start-stop fault light flashes?

1. Poor combustion state: Poor combustion state of the engine is the main reason why the engine fault light is on.

2. Reason, for reference only: sensor damage, poor contact or signal interruption;Poor engine maintenance; poor quality of fuel and oil; insufficient combustion of mixed gas; spark plug failure, ignition coil failure; fuel pump failure, oil line blockage; air conditioning filter blockage.

3. First, press the ignition switch twice, and pay attention that there is no need to step on the brake at this time. Secondly, press and hold the istop switch button for 10 seconds to start the car and turn the steering wheel from the leftmost to the rightmost. Finally, turn off the engine and it will be eliminated after 10 minutes.

4. This is due to the imbalance of the proportion of the mixed gas after the problem of the oxygen sensor, which is easy to cause the engine failure light to turn on. When the temperature controller finds an abnormality, the engine fault indicator light will also light up. If the water temperature cannot be raised to the ideal temperature for a long time in the car body, the engine fault indicator light will flash.

5Like our vehicles, there are usually many sensors, such as water temperature sensors, oxygen sensors, etc. When the sensors are damaged or have poor contact, the engine fault light will turn on.

6. There are seven main reasons why the fault light of Qijun's engine is on: Fault: 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, the ECU of the car cannot accurately obtain the engine data, which will cause the engine fault light to light up.

Qijun engine fault light on

1. [Pacific Automobile Network] Qijun engine fault light on There are 4 main reasons: 1. The combustion condition is not good, 2, the use of poor quality fuel, 3, there is carbon accumulation in the engine cylinder, 4, the engine explosion. The engine failure signal is sent by the car engine computer.

2. Poor combustion state: Poor combustion state of the engine is the main reason why the engine fault light is on.

3. Exhaust problem: Exhaust failure will also cause the engine fault light to light up. Post-oxygen sensor, ternary catalyst, exhaustThe failure of camshaft and shaft tile is the cause of exhaust problems, among which ternary catalysts are the most common.

4. Like our vehicles, there are usually many sensors. The more common ones are water temperature sensors, oxygen sensors, etc. When the sensors are damaged or the contact is poor, the engine fault light will turn on.

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 main reason why the fault light of Qijun engine is too much carbon accumulation in the throttle valve or inside the engine, resulting in unstable idle speed and dirty throttle valve.This is because the oxygen sensor fails, causing the mixing gas to be out of proportion, which is easy to cause the engine failure light to turn on. When there is an abnormality in the thermostat, the engine fault light will also turn on.

2014 Qijun, engine fault light on

1. Poor operation of the engine system will also cause the fault light to turn on, such as accelerator pedal sensor, throttle position sensor, air flow meter and crankshaft position There is a problem with the sensor, or the line contact is poor, etc.

2. If the anti-skid light on the dashboard is on, the road surface may be indeed mild and slippery, causing ABS to work, so it will light up; ABS pump failure; there is an error in signal transmission, and if the computer's false alarm is on for a long time, there will definitely be a problem. At this time, it should be repaired as soon as possible.

3. If the fault light of Qijun engine is on, it means that there is a fault in the engine. It needs to troubleshoot in time, and then use the decoder to eliminate the fault code. If there is no fault, the fault code should be cleared directly.

4. The main reason why the fault light of Qijun engine turns on is that there is too much carbon accumulation in the throttle valve or inside the engine, resulting in unstable idle speed and dirty throttle valve. This is because the oxygen sensor fails, causing the mixing gas to be out of proportion, which is easy to cause the engine failure light to turn on. When there is an abnormality in the thermostat, the engine fault light will also turn on.

5. The poor combustion state of the engine is the main reason why the engine fault light is on. Engine shock is also the reason why the engine fault light is on. The intrinsic reason why the engine fault light is on: the fuel quality is poor, the inside of the engine cylinder is unclean, and there is deposited carbon.

6. Poor combustion state: Poor combustion state of the engine is the main reason why the engine fault light is on.
