19 Qi Jun engine fault light flashes?

19 Qi Jun engine fault light flashing reasons: 1, sensor damage, poor contact or signal interruption; 2. Poor engine maintenance; 3. Poor quality of fuel and engine oil; 4. Incomplete combustion of mixed gas; 5, spark plug, ignition coil failure; 6, fuel pump failure, oil blockage; 7. The air conditioning filter element is blocked.

The main reason of Qi Jun engine fault light is that the throttle or engine has too much carbon deposit, which leads to unstable idle speed and unclean throttle.

This is because when the oxygen sensor fails, the mixing ratio is unbalanced, which easily leads to the engine failure light. When the thermostat is abnormal, the engine fault light will also light up.

If you don't see the water thermometer rise to the ideal temperature for a long time in the car body, the engine fault light will light up.

The reasons for the failure light of Nissan Qi Jun engine are as follows:

1, the exhaust emission is not up to standard, such as poor fuel, failure of three-way catalyst, excessive carbon deposition in intake pipe, blocked fuel nozzle, failure of oxygen sensor, occasional misfire of engine, etc. , engine fault lights will be on, and poor oil quality will lead to the most engine fault lights;

2. The fault light is on due to poor engine system, such as the fault of accelerator pedal sensor, throttle position sensor, air flow meter and crankshaft position sensor. Or poor line contact, etc. , it will cause the engine fault light to light up;

3. Some vehicle gearbox system failures are also indicated by engine failure lights, such as internal gearbox failures, slippage, high temperature, etc.
