What is the fault when the SVS light is on?

[DiHaven]

SVS light on indicates an engine fault. When the engine detects a fault, the SVS light illuminates to alert the driver of an engine issue. Encountering the SVS light while driving may be due to improper driving. Below are related explanations: 1. Light on while driving: If the SVS light comes on during driving, it signifies an abnormality in the vehicle's powertrain system, which may result in loss of power and inability to move. It could also be caused by improper exhaust emission, where excessive emissions trigger the SVS light to flash as a warning. 2. Light on during ignition: If the SVS light turns red or yellow during ignition, it might be due to the use of ethanol-blended fuel. 3. Engine maintenance: Daily use inevitably causes wear and tear on the engine, making regular maintenance essential. There are various reasons for engine damage, so it is advisable to visit a 4S shop for a systematic inspection to determine the cause of the SVS light illumination and the underlying engine fault.
