Frequently Asked Questions

What is the first thing to check when the check engine light comes on in a 2023 Toyota Sequoia?

• Check for a loose or missing gas cap first — it’s a common, simple cause and can trigger an emissions fault code.
• Confirm obvious signs: unusual noises, loss of power, or smells that indicate a more urgent issue.
