What does the SVS light in a car mean?

[OVera]

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 is started; 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 that there is a fault with the vehicle's engine, and it needs to be repaired as soon as possible. The following is an introduction to the ECU: 1. The role of the ECU: The ECU can collect data through various sensors, and after processing, it can control the engine's operation through control mechanisms. Without the ECU and sensors, the engine cannot function properly. 2. The principle of the ECU: The principle of the ECU is to detect the engine's working conditions through sensors installed in different locations, including engine speed, crankshaft position, exhaust temperature, exhaust oxygen content, and other parameters, and send these signals to a dedicated microprocessor, which processes them and issues control signals to adjust the engine's ignition timing and fuel supply in a timely manner, achieving the desired optimal effect.
