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

• Start with simple visual checks: ensure the gas cap is tight and intact — a loose cap is a common trigger for the light.
• Look for obvious leaks, unusual smoke, or dashboard warnings that suggest a more urgent problem.
• Check fuel level and recent driving conditions—short trips and cold starts can cause transient codes.
• If the light remains, bring your 2026 Toyota Crown to Bill Estes Toyota for a fast diagnostic scan handled by factory-trained technicians.
• For warranty work, repairs must be completed at a certified dealership to protect your coverage and deliver the best savings long term.

What is the most common reason for check engine light on a 2026 Toyota Crown?

• Frequent causes include faulty oxygen sensors, loose gas caps, evaporative emissions (EVAP) leaks, and ignition misfires (spark plugs or coils).
• Oxygen sensors and EVAP issues often trigger emissions-related codes that affect fuel economy if left unaddressed.
• Ignition misfires can cause a flashing light and risk catalytic converter damage if not repaired promptly.
• Bill Estes Toyota prioritizes accurate diagnosis and uses genuine parts, which often results in lower overall cost than repeated repairs at independent shops.
• Remember: warranty-covered repairs must be performed at a certified dealership to keep your coverage valid.

How long does a check engine light service take?

• A basic OBD-II scan and initial diagnosis typically take 20–60 minutes, depending on shop queue and system checks.
• Comprehensive diagnostics, including test drives and component testing, often require 1–3 hours to pinpoint root causes.
• Simple repairs can be same-day; more involved fixes (parts orders, emission repairs) may take longer — we communicate timelines clearly and promptly.
• Because Bill Estes Toyota stocks many OEM parts and employs factory-trained techs, turnaround is efficient and often faster than independent alternatives, delivering immediate and long-term savings.
• If an issue falls under warranty, repairs must be completed at a certified dealership to maintain coverage; we handle those claims directly for your convenience.
