• Observe dashboard indications: reduced power, odd noises, or a flashing light signal higher urgency and need immediate inspection.
• A simple scan at our service center will read stored codes; diagnosing early prevents secondary damage and saves money long term.

How long does a check engine light service take?

• Initial diagnostics typically take 30–90 minutes depending on the symptoms and whether road testing or extended scanning is required.
• Simple fixes (like replacing a gas cap or clearing a code after repair) can be completed the same day; more involved repairs depend on parts and the required labor.
• At Toyota of Greenville we prioritize accuracy to avoid repeat visits — that approach often lowers total ownership costs versus multiple quick fixes from independent shops.
• For warranty-related repairs, certified dealership service ensures work meets factory standards; we’ll provide a clear timeline and cost estimate before proceeding.
