How to solve the trouble light of Nissan Teana engine?

The fault light of Nissan Teana engine is on, mainly due to the fault of engine electronic control system. I suggest you go to the repair shop to read the fault code with the decoder, and then repair it.

The main reason why the engine fault light comes on is that the throttle valve or the engine has too much carbon deposit, and the oxygen sensor fails, which leads to the imbalance of the mixture ratio, so it is easy for the engine fault light to come on. If you drive at a low speed in the urban area for a long time, this phenomenon is easy to appear. If detected by other diagnostic computers, the fault code may be wrong. I suggest you go to a regular 4S shop for inspection. Although it is no problem to continue to use the vehicle after the engine fault light is on, such long-term use will definitely increase the fuel consumption of the engine, so I suggest you determine the cause of the fault and eliminate it.

The engine fault light does not mean that the engine cannot work. First of all, when the fault light is on, it is necessary to check the maintenance. If you happen to be near the pit, you can check it at any time. If you are far from the pit and just don't have time to check, you can do your own thing first.
