What does the SVS light on the car dashboard mean?

The SVS light on the car dashboard refers to the engine malfunction indicator. Cleaning the air filter: The air filter is related to the engine's air intake during driving. If the air filter is clogged or accumulates excessive dust, it can cause poor engine air intake. Additionally, a large amount of dust entering the cylinders will accelerate carbon buildup, leading to poor engine ignition, insufficient power, and naturally increased fuel consumption. Removing throttle valve sludge: Sludge is formed due to carbon deposits from fuel combustion exhaust at the throttle valve, as well as impurities not filtered by the air filter accumulating there. Excessive sludge can cause air intake resistance, leading to increased fuel consumption. Cleaning injector carbon deposits: Since the combustion chamber is prone to carbon buildup, which can cause difficulty in starting, carbon deposits on the injectors can also block fuel passages, distort fuel injection, and result in poor atomization, naturally increasing fuel consumption.
A few days ago, I also encountered the SVS warning light popping up on my dashboard while driving, and it really gave me a scare. After checking some materials, I learned that SVS stands for "Service Vehicle Soon," indicating that the vehicle needs servicing as soon as possible. The most common causes are faults in the engine emission system, such as abnormal oxygen sensors or catalytic converters; it could also be an electrical issue, like a loose sensor connection or an error reported by the electronic control unit. In some cases, you might still drive a short distance, but if accompanied by engine shaking or loss of power, you should never push it. I recommend pulling over immediately, turning on the hazard lights, and contacting a 4S dealership for towing and inspection—trying to fix it yourself could make things worse. A friend of mine ignored this warning light and drove for two weeks, ending up spending over 8,000 yuan to repair the transmission. A painful lesson indeed!
