What does it mean when the car displays SVS?

[LeDominic]

SVS indicator light is the engine fault indicator light, which is equivalent to the 'engine shape' indicator light. When the vehicle's ignition key is turned on, this light will illuminate and will turn off after the vehicle starts. When the engine ECU detects a fault, the SVS light will illuminate. If this light comes on while the vehicle is in motion, it indicates a fault in the vehicle's engine. The reasons for the car engine fault light coming on are: 1. Poor gasoline quality leading to incomplete combustion of the air-fuel mixture in the cylinder, resulting in carbon deposits; 2. The engine has been driven for too long, causing the spark plugs' working characteristics to weaken; 3. Mechanical aging of the vehicle; 4. Damage, poor contact, or signal interruption of the water temperature sensor, crankshaft position sensor, air flow sensor, intake air temperature sensor, or oxygen sensor. The solutions for the car engine fault light coming on are: 1. Promptly check the condition of the car engine; 2. Inspect the condition of the car's sensors, air flow sensor, and spark plug components; 3. Check for any knocking in the car; 4. Inspect the ignition coils for any faults.
