The reasons why the Buick Verano engine malfunction light turns on are as follows:
1.

The sensor and occasional misfire in the engine will cause the check engine light to illuminate, among which the check engine light is most often caused by poor oil quality;
2 . The fault light comes on due to poor oil quality. The operation of the engine system, such as accelerator pedal sensor, papill position sensoron, air flow sensor, crankshaft position, sensor faults or poor circuit contact will cause the engine trouble light to illuminate;
3. Faults are also indicated by the engine fault light, such as internal gearbox faults, slippage, high temperature, etc.
This car is very new and there will be no serious problems with carbon deposits. There is no problem with the accessories. We should consider the oil circuit problem. Maybe Yue magazine's fuel sometimes exceeds the standards. standard during recent refueling. Fuel from Sinopec Petroleum will also be the cause of the problem.
