A flashing malfunction indicator lamp (MIL), commonly known as a check engine light, signals a severe engine problem demanding immediate attention. This alert indicates that a misfire is occurring, potentially damaging the catalytic converter and other vital engine components. Continued operation of the vehicle in this condition can lead to costly repairs.
Addressing this warning promptly is critical to preserving engine health and preventing further degradation. Ignoring a flashing MIL can result in significant financial burden and potential safety hazards. The system’s history involves progressively sophisticated diagnostic capabilities, allowing for quicker and more accurate identification of underlying issues, thus minimizing downtime and repair expenses.
