What happened to the fault light of Zhengzhou Nissan Odin diesel engine?

Too much carbon deposit in throttle or engine.

1. Too much carbon in the throttle or engine.

2. When the oxygen sensor fails, the mixing ratio is unbalanced. If you drive at a low speed in the urban area for a long time, it is easy to appear this phenomenon.

3. The nozzle leaks air, which leads to the nozzle still being in the oil supply state after the throttle valve is closed, which leads to the excessive mixture when driving at low speed, which leads to the unstable idle speed after the oil is closed. If it is serious, turn it off directly.

4. The oxygen sensor was poisoned by adding inferior gasoline with excessive metal content. The solution is to change to a gas station.
