Can the Buick Excelle continue to drive when the engine yellow light is on?
1 Answers
The engine yellow light on the Buick Excelle indicates that there is a problem with a certain part of the vehicle, but it is not too serious. You can continue to drive, but it is necessary to go for repair as soon as possible. Reasons for the Buick Excelle engine yellow light being on: Sensor issues: When sensors such as the water temperature sensor, crankshaft position sensor, air flow sensor, intake air temperature sensor, or oxygen sensor are damaged, have poor contact, or signal interruption, the car's ECU cannot accurately obtain the engine's data, which will cause the engine fault light to turn yellow and illuminate. Fuel quality issues: If the car is not filled with the corresponding model of fuel as required, it will cause engine wear over time, leading to the fault light turning on. Poor combustion of the air-fuel mixture: Engine problems such as spark plug failure, ignition coil failure, fuel pump failure, or fuel line blockage can all cause poor combustion of the air-fuel mixture in the engine. Poor combustion of the air-fuel mixture leads to engine carbon deposits or knocking problems. When detected by the engine's oxygen sensor, the fault light will illuminate as a warning.
