Frequently Asked Questions

What is the first thing to check when the check engine light comes on in a 2024 Toyota Sienna?

• Check the gas cap: a loose or damaged fuel cap is a common, simple cause and can trigger the light.
• Look for obvious issues: low oil, odd smells, visible leaks or smoke — stop driving if you see any of these.
• Note performance changes: hesitation, stalling, or loss of power indicates a more serious fault needing diagnostics.
• If the light persists after basic checks, bring the vehicle to Bill Estes Toyota for a professional scan and repair.

What does it mean when the check engine light comes on in a 2024 Toyota Sienna?

• Causes range from minor EVAP leaks or a loose gas cap to sensor failures, ignition misfires, or catalytic converter problems.
• Some issues are safe to drive on briefly; others require immediate service—diagnosis determines urgency.
