What is the first thing to check when the check engine light comes on for a 2024 Toyota Grand Highlander Hybrid?

• Start with basics: ensure the gas cap is tight and undamaged — a loose cap is a common, easy-to-fix cause of an emissions code.
• If tightening the cap doesn’t help, bring the vehicle in so we can scan codes, inspect sensors, and test fuel and ignition systems safely and accurately.
• Our dealership’s diagnostic process is efficient and cost-effective; addressing small issues early reduces fuel waste and prevents amplified repair bills.
• Remember: warranty repairs must be done at a certified dealership like Nalley Toyota Stonecrest to keep coverage intact and ensure proper parts and procedures are used.

• Frequent triggers include oxygen sensor faults, EVAP system leaks (often from a loose gas cap), and occasional misfires due to spark or fuel system issues.

• Nalley Toyota Stonecrest’s factory-trained technicians use OEM diagnostic tools to pinpoint problems quickly, often saving customers money over independent shops by preventing repeat visits.
• Warranty-covered repairs must be completed at a certified dealership to preserve benefits and ensure genuine parts and correct procedures are used.
