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

• The light signals the vehicle’s onboard diagnostics detected an issue—anything from an emissions sensor to an engine misfire.
• Common triggers include oxygen sensors, catalytic converter issues, misfires, or evaporative system leaks; each requires a scan to identify the exact code.
• Immediate diagnostics help determine severity: some codes are informational, others indicate urgent mechanical faults that affect safety or emissions.
• Our technicians use factory-level tools to read codes, interpret manufacturer data, and recommend repairs that protect performance and fuel economy.

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

• Start with simple checks you can do safely: ensure the gas cap is tight and undamaged—an unsecured cap is a common trigger.
• Note any performance changes (loss of power, rough idle, stalling) and report them when you bring the vehicle in; symptoms guide priority.
• Avoid clearing the light yourself; resetting without repair can mask problems and may void warranty coverage—warranty repairs must be handled by a certified dealership.
• Contact Bill Estes Toyota to schedule a prompt diagnostic so factory-trained technicians can identify and resolve the issue correctly.
