What Does the Yellow Engine Symbol Mean?

[KingstonLee]

When the yellow engine indicator light comes on, it indicates a fault in the engine. Relevant details are as follows: 1. Common reasons for the yellow light to illuminate include: a dirty throttle body, poor fuel quality, a faulty oxygen sensor, a clogged catalytic converter, and other typical issues. The impact on vehicle safety can vary, so the owner should promptly have the engine system inspected. 2. Reasons for the engine fault light to illuminate: Poor or substandard gasoline quality. This usually occurs when low-quality fuel is added at an unregulated gas station, leading to incomplete combustion of the air-fuel mixture during engine operation and triggering the engine fault light. While this does not affect driving safety, it may cause some degree of harm to the engine.
