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

• Check the gas cap — a loose or damaged cap is a frequent, easy-to-fix cause that can trigger the light.
• Look for other dashboard warnings, unusual noises, or reduced performance; note when symptoms began and any recent fuel stops.
• Use a reliable OBD-II scan to capture trouble codes; our service team performs this quickly and interprets results for you.
• If the light is flashing or performance is compromised, stop driving and bring the vehicle to Bill Estes Toyota immediately to avoid further damage.

How long does a check engine light service take?

• Initial code reading typically takes 20–45 minutes; a full diagnostic visit commonly completes in 1–3 hours depending on complexity.
• Simple repairs can often be done the same day; more involved repairs that require parts or deeper inspection may take longer.
• At Bill Estes Toyota we provide a clear time estimate before work begins and use OE parts and factory-trained techs for efficient, lasting results.
• Choosing the dealership often yields immediate and long-term savings by avoiding repeat repairs and ensuring warranty-eligible work is documented properly.
