What Causes the Engine Indicator Light to Illuminate?
1 Answers
What Causes the Engine Indicator Light to Illuminate: 1. Poor Combustion State: The primary reason for the engine fault light illuminating is poor combustion within the engine. Inaccurate coordination between engine components leads to suboptimal combustion, triggering the engine indicator light. 2. Engine Knock: The engine indicator light will also illuminate when engine knock occurs. Engine knock manifests as reduced vehicle power, excessive engine noise, and noticeable piston slap sounds. 3. Internal Causes for Engine Fault Light: Poor fuel quality or severe carbon buildup inside the engine cylinders can also cause the engine fault light to illuminate. It is essential for the owner to promptly inspect the engine's working condition to prevent more significant failures.
