Frequently Asked Questions

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

• Confirm the condition of the gas cap—tighten it and re-check after a few drives; a loose cap is a common cause on a 2025 Toyota GR86.
• Scan for codes with an OBD-II reader; codes point to the subsystem needing attention rather than guessing.
• Quick visual checks: fluid levels, battery terminals, and obvious wiring or vacuum leaks under the hood.
• If the light stays on after basic checks, bring your vehicle to Toyota of Greenville—warranty repairs must be done at a certified dealership to preserve coverage.

How long does a check engine light service take?

• Basic diagnostics typically take 30–90 minutes for a 2025 Toyota GR86, depending on whether codes point to a single sensor or a deeper issue.
• Simple fixes like replacing a gas cap or oxygen sensor can often be completed the same day.
• Complex repairs (misfires, catalytic converter) may require parts ordering and can take one to several days.
• At Toyota of Greenville, factory-trained technicians and efficient workflows help reduce downtime and deliver immediate and long-term savings versus many independent shops.
