What does it mean when the check engine light comes on in a 2025 Toyota Corolla Hatchback?

• The light signals that the vehicle’s onboard computer has detected a system irregularity—ranging from minor (evap leak) to serious (misfire).
• It does not always mean a safety emergency, but it does require a diagnostic scan to read stored trouble codes and confirm severity.
• Certain conditions will trigger a steady light; a flashing light usually indicates active misfires or catalytic converter risk and needs immediate attention.
• At Coggin Toyota at the Avenues, we use OEM-grade scanners and factory knowledge to diagnose accurately, often saving you time and money versus improper repairs.

What is the first thing to check when the check engine light comes on?

• Start with simple checks: ensure the gas cap is tight and intact—this is a very common cause of an illuminated light.
• Note vehicle symptoms: rough idle, loss of power, or unusual noises; record when the light started and any recent fueling or maintenance.
• If the light is flashing, stop driving and have the vehicle inspected immediately to avoid engine or catalytic converter damage.
