Why does the check vsc chose while I am driving?

The check engine light may illuminate while driving for various reasons, including issues with the vehicle's engine, transmission, or exhaust system. It could indicate a minor problem, like a loose gas cap, or something more serious, such as a malfunctioning sensor or a failing catalytic converter. It's essential to have the vehicle checked by a mechanic to diagnose the specific issue and prevent potential damage. Ignoring the light can lead to decreased performance or costly repairs down the line.
