Lada vehicles incorporate an advanced sensor network that continually monitors engine performance and emissions, triggering the check engine light when key diagnostic codes--such as misfire events, oxygen sensor failures, or catalytic converter malfunctions--are detected. This alert serves as an essential, data-driven signal designed to prioritize immediate technical assessment using OBD-II diagnostics, ensuring that even minor sensor discrepancies or more significant system faults are promptly addressed. By reviewing these specific error codes and consulting authorized Lada service centers, owners can efficiently determine whether routine sensor recalibration or comprehensive engine repairs are necessary, thereby maintaining the vehicle's reliability, performance, and safety.
