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

• The light signals the vehicle’s onboard diagnostics detected an issue—ranging from minor EVAP leaks to ignition misfires or emissions control faults.

• Severity varies: some codes are informational, others indicate conditions that can damage the engine or emissions system if ignored.
• Bring your Grand Highlander to Bill Estes Toyota for a precise scan; our technicians interpret codes, diagnose root causes, and recommend repairs that save you money over time.

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

• Start with the simple checks: ensure the gas cap is tight and check for obvious fluid leaks or unusual smells.
• Look for messages on the dashboard or reduced power modes; note driving symptoms such as rough idle, stalling, or loss of power.
• If symptoms are mild, schedule a diagnostic scan with Bill Estes Toyota promptly to avoid escalation—diagnostics are fast and can prevent costlier repairs.
• If the light is flashing or the vehicle runs poorly, stop driving and bring it to our certified service team immediately to protect the engine and emissions systems.

How long does a check engine light service take?

• Basic code reads and a visual inspection typically take 30–60 minutes; more involved diagnostics or road tests can extend time to 1–3 hours.
• Simple repairs like tightening a gas cap or replacing a sensor may be completed the same day; complex repairs (e.g., catalytic converter replacement) take longer due to parts and labor requirements.
• Bill Estes Toyota schedules work efficiently and uses OEM parts so repairs are done right the first time, saving you time and future expenses.
• If repairs fall under warranty, they must be completed at a certified dealership—this ensures coverage and long‑term savings compared with repeated independent work.
