What does the SVS light on the dashboard mean?

[OJeffrey]

SVS stands for the engine fault indicator light. Reasons for the engine fault light to illuminate: 1. Poor engine combustion is the primary cause of the engine fault light coming on; In automotive design, to ensure the engine operates in good condition and maintains a normal service life, an oxygen sensor is installed to monitor the engine's combustion state. Poor combustion not only pollutes the environment but also leads to fuel waste and excessive engine wear. 2. In real-life situations: Some gas stations may not fully comply with standards to provide fuel suitable for high-performance engines, resulting in frequent occurrences of the engine fault light illuminating. 3. Over time, carbon deposits inevitably accumulate inside the engine. These deposits can alter the engine's design parameters and, due to their unstable nature, retain heat. The retained heat can cause uncontrolled ignition, leading to engine knocking. In such cases, the engine fault light will also illuminate.
