Can the Teana still be driven if the engine yellow light is on?

Teana engine yellow light on indicates that there is a problem with the engine. If there are no other abnormalities in the car, it can still be driven. Reasons why the engine fault light is on: Exhaust emissions do not meet standards, fuel injector is clogged, throttle position sensor, and some vehicle transmission system faults are also indicated through the engine fault light. Two situations when the engine yellow light is on: The first is when the car's power is turned on, the vehicle will perform a self-check. At this time, not only the engine yellow light is on, but other fault lights will also light up together, and then they will all go out. The second is when the car is started, the engine fault yellow light remains on. This is the ECU reminding that there is a fault in the engine, which is an abnormal phenomenon.
The other day, the engine warning light in my Teana suddenly turned yellow, which made me a bit nervous. However, since the car was still drivable, I slowly drove to a repair shop near my neighborhood. The mechanic scanned the fault code with a device and said it was a minor issue with the exhaust sensor—nothing serious. After replacing it, everything was fine. Actually, when the light is yellow, the car can still be driven; it's not as dangerous as when it's red. But it's best to avoid prolonged high-speed driving or carrying heavy loads to prevent the problem from worsening and damaging the engine. It's a good idea to first check if the fuel level is sufficient or if the gas cap is tightly closed. If simple fixes don't work, take it for a professional inspection right away—it saves money and hassle. After experiencing this minor issue, I now pay more attention to regular maintenance to avoid trouble during trips. Safe driving is always the top priority.
