What Causes the Engine Warning Light to Illuminate After Accelerating?

[LaCaleb]

After accelerating, the engine warning light may illuminate due to using the wrong fuel grade or poor fuel quality. Poor fuel quality can lead to incomplete combustion in the engine, which in turn causes excessive emissions. The emission system detects this and interprets it as an engine malfunction, triggering the engine warning light. The car engine is the power-generating unit of a vehicle, often referred to as the heart of the car, determining its power, fuel efficiency, stability, and environmental performance. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems, among others.
