What does it mean when the check engine light comes on in a 2026 Toyota Grand Highlander Hybrid?

• The light signals the vehicle’s onboard diagnostics detected an issue—from minor sensor faults to engine or emissions problems.
• Common causes include oxygen sensor faults, evaporative system leaks, misfires, or catalytic converter inefficiency.
• Immediate dealership diagnostics determine severity and prevent small issues from escalating into costly repairs.
• Choosing our certified service delivers accurate diagnosis, factory parts, and warranty protection, which yields better long-term value than piecemeal fixes.

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

• Our technicians check pending codes, readiness monitors, and live data to identify root causes quickly, saving you time and money.
• Repairs covered by warranty must be completed at a certified dealership to maintain coverage and receive factory-trained technician care.

How long does a check engine light service take?

• Initial diagnostics typically take 30–60 minutes using OEM-grade scanners and hybrid-specific procedures to read codes and live data.
• Minor repairs, such as replacing a sensor or tightening a gas cap, can often be completed the same day.
• More extensive repairs or parts orders may require additional time; we provide transparent timelines and loaner options when available.
• Our factory-trained technicians and direct access to Toyota parts reduce turnaround time and deliver better long-term savings than repeated independent attempts.
