What are the effects of the SVS light being on?
2 Answers
SVS light coming on indicates that there is a fault in the engine, and it needs to be inspected and repaired at a 4S shop. Here is some relevant information about the SVS indicator light: Working principle: When the ignition key is turned on, this light will illuminate and will turn off after the vehicle starts. If the engine ECU detects a fault, the SVS light will also come on. If this light comes on while the vehicle is in motion, it indicates that there is a fault in the vehicle's engine. Function of the SVS fault light: The SVS fault indicator is a warning light that alerts the owner when the ECU or TCU of an electronically fuel-injected car detects a problem with the engine or automatic transmission. As soon as this light comes on, it is recommended that the owner takes the vehicle to a repair shop for inspection as soon as possible.
The SVS light comes on primarily when the vehicle's system detects an issue requiring service. This warning signal should not be ignored, as it indicates potential faults in the electronic control unit or sensors, such as abnormal emission systems or decreased engine performance. If not addressed promptly, it can affect driving safety, for example, causing insufficient power or stalling on highways. The last time I encountered this light, it was due to an emission control problem—the car felt sluggish, and fuel consumption increased. I immediately took it to a professional repair shop where diagnostic tools revealed an aging oxygen sensor. Delaying repairs could further damage the catalytic converter, leading to repair costs of thousands of dollars and affecting annual inspections. Regular maintenance can prevent such issues, but once the light comes on, don't delay—safety comes first.
