What does it mean when the check engine light comes on in a 2024 Toyota Highlander Hybrid?

• It signals that an onboard sensor or system detected a fault—anything from a loose gas cap to an emissions or engine misfire.
• Some faults are maintenance reminders; others can affect drivability or damage components if ignored.
• We recommend scanning the vehicle with a professional OBD-II tool to read stored codes and determine urgency.
• Our technicians interpret codes in context—symptoms, freeze-frame data, and vehicle history—to avoid unnecessary repairs.
• If covered under warranty, repairs must be performed by a certified dealership to ensure full protection.

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

• Start with easy checks: ensure the fuel cap is tight and properly sealed; a loose cap is a common trigger.
• Note any drivability issues—loss of power, rough idle, or excessive smoke—and avoid hard driving if present.
• Bring the vehicle to Bill Estes Toyota for a prompt scan so technicians can read codes and assess severity.
• Do not reset the light until the cause is diagnosed; resetting can mask a developing problem and void warranty coverage for related repairs.
• Certified dealerships provide documented diagnostics that protect long-term value and warranty eligibility.

How long does a check engine light service take?

• Basic diagnostics often take 30–90 minutes to read codes, run quick tests, and advise on next steps.
• Repair times vary: simple fixes (e.g., gas cap, sensor replacement) can be same-day; complex repairs may require parts ordering and a day or more.
• Bill Estes Toyota offers efficient scheduling, express lanes, and OEM parts sourcing to minimize downtime.
• Choosing dealer service often reduces repeat visits and long-term costs thanks to precise diagnostics and factory procedures.
• Warranty repairs must be completed at a certified dealership to ensure coverage and proper documentation.

What is the most common reason for check engine light on a 2024 Toyota Highlander Hybrid?

• Common triggers include a loose gas cap, failing oxygen sensors, and intermittent engine misfires.
• Emissions system issues (catalyst or evap system) and aged sensors can also illuminate the light.
• Regular maintenance and prompt diagnostics reduce the likelihood of expensive downstream repairs like catalytic converter replacement.
• Our technicians identify root causes—rather than just replacing parts—to preserve fuel economy and performance.
• If your vehicle is under warranty, have repairs done at a certified dealership to preserve coverage and long-term savings.
