When your Rover's check engine light illuminates, it indicates that the vehicle's onboard diagnostic system has detected sensor anomalies or performance issues--ranging from emissions irregularities and misfires to fuel system or catalytic converter concerns--that require immediate attention. This advanced alert system relies on real-time data collected from critical components to generate specific diagnostic trouble codes (DTCs), which technicians can retrieve using an OBD-II scanner. Interpreting these codes is crucial for pinpointing the root cause, allowing for timely maintenance and ensuring that your Rover maintains its optimal performance, fuel efficiency, and overall reliability.
