What does it mean when the SVS light on the car dashboard is on?

The SVS light on the dashboard indicates that the engine control unit has detected an error signal from a certain sensor or that it has exceeded the standard usage limits. Below is an introduction to the SVS light on the dashboard: 1. Try to start the engine. If it fails to start, it could be due to an abnormal fuel pump that cannot supply fuel to the engine properly; if it can still start, it might be a fault with other sensors. In this case, the car can still be driven, but other factors affecting normal vehicle operation cannot be ruled out, such as increased fuel consumption or body shaking. 2. Check if other car equipment shows abnormalities, such as the water 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 car to a repair shop for inspection. 3. If accompanied by signs such as increased combustion chamber temperature or the oil pressure warning light, continuing to drive may lead to aggravated engine wear and premature engine damage.
Last time my car's SVS light suddenly came on, which really made me nervous. SVS stands for Service Vehicle Soon, which basically means the vehicle needs to be serviced. Common causes include engine sensor failure, emission system issues, or the computer detecting abnormal signals. For example, I once had a faulty oxygen sensor that caused excessive emissions. At that time, I promptly drove to the 4S shop for inspection. The technician quickly diagnosed the problem using a scanner and fixed it. If you ignore it, your car might experience slower acceleration or even break down on the road. I recommend not delaying and scheduling a check-up the same day. While you're at it, have the engine oil and coolant levels checked to ensure safe driving. Regular maintenance can really prevent many of these minor issues, saving you both hassle and money.
Having worked in an auto repair shop, the SVS light indicates that the vehicle requires service, often signaling a fault reported by the onboard system. Common issues include a clogged catalytic converter, loose sensors, or circuit problems. We typically plug in a diagnostic tool to read the fault codes and perform targeted repairs. If you see the light on, don't panic; drive slowly to the repair shop for inspection. Delayed action may lead to reduced engine efficiency or increased fuel consumption. Additionally, during the inspection, it's advisable to check the condition of the spark plugs and air filter for comprehensive prevention. In most cases, replacing a small part solves the problem, which is both cost-effective and efficient.
