2 Answers
SVS displayed on the car dashboard refers to the engine fault indicator light. The reasons for its illumination are: 1. Fuel emission system malfunction; 2. Intake tract malfunction; 3. Spark plug carbon buildup; 4. Sensor malfunction; 5. Poor fuel quality; 6. Engine carbon buildup; 7. Three-way catalytic converter malfunction; 8. Engine detonation. The solutions for the engine fault indicator light illumination are: 1. Check if the oxygen sensor connector is loose; 2. Clean the spark plugs; 3. Replace the oxygen sensor; 4. Replace the three-way catalytic converter; 5. Clean the engine; 6. Drain the old gasoline from the fuel tank and replace it with high-quality gasoline.
I drive frequently, and when the SVS light comes on the dashboard, I know it's time to get the car repaired. SVS stands for Service Vehicle Soon, meaning the vehicle requires maintenance as soon as possible, possibly due to issues in the engine system, such as abnormal data detected by sensors or low oil pressure. Common causes include faulty oxygen sensors or malfunctioning air mass flow meters, which can affect engine performance. Last year, during a long-distance drive, this light came on, and after inspection, it turned out to be an error reported by the electronic control unit. Delaying the fix even led to higher fuel consumption. I recommend consulting a professional technician with a diagnostic scanner as soon as you see the light to quickly identify the issue. Paying attention to regular maintenance schedules, such as timely oil changes or air filter replacements, can also reduce the chances of the SVS light coming on, as it's a significant safety hazard while driving.
