Is the SVS light on the car dashboard serious?
2 Answers
At this time, the vehicle condition is quite serious. When the SVS light appears on the dashboard, it indicates a fault in the vehicle's engine. The driver should immediately stop the car in a safe manner and contact professional maintenance personnel for repairs. Here are the relevant details: Reasons for the SVS light to illuminate: The SVS light is similar to the engine fault light. When the SVS indicator lights up, it means the engine control unit has detected an error signal from a sensor or that the sensor has exceeded its standard operating parameters. When the ignition is turned on, the SVS light will illuminate briefly for an automatic check and then turn off after a few seconds, indicating that the vehicle is safe to drive. How to handle the SVS light: First, check if other vehicle systems are showing abnormalities, such as the coolant temperature gauge or oil pressure warning light. If only the SVS light is on and the engine can still start, drive cautiously, control your speed, and promptly take the vehicle to a repair shop for inspection. If symptoms such as increased combustion chamber temperature or the oil pressure warning light accompany the SVS light, continuing to drive may lead to accelerated engine wear and premature engine damage.
I immediately became alert when I saw the SVS light illuminate on the dashboard. This light stands for 'Service Vehicle Soon,' indicating that the vehicle requires maintenance. While it's not as urgent as the engine fault light, it should never be ignored. Last time my car had this light on, it was due to an issue with the oxygen sensor. Although the car was still drivable, fuel consumption surged by 20%. I recommend first listening for any unusual engine noises and checking if the fuel cap is tightened properly. If the light remains on for more than two days, it's essential to visit a professional repair shop to connect an OBD scanner and read the fault codes. Typically, it's related to the emission system, sensors, or circuit faults. Delaying repairs could lead to the failure of the catalytic converter, which could cost you five to six thousand yuan. By the way, some older vehicles might falsely trigger this light due to unstable battery voltage.
