What Causes the Yellow Engine Light to Illuminate?
1 Answers
There are two main reasons why the yellow engine light illuminates: 1. When the vehicle's power is turned on, the system performs a self-check. During this process, not only the yellow engine light but also other warning lights will illuminate simultaneously before turning off, which is a normal phenomenon; 2. If the yellow engine warning light remains on after starting the car, this indicates that the ECU is alerting you to an existing engine fault. The automobile engine serves as the power-generating device for vehicles, functioning as the heart of the car that determines its power performance, fuel efficiency, stability, and environmental friendliness. Depending on their power sources, automotive engines can be categorized into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid systems.
