What does it mean when the check engine light comes on in a 2025 Toyota GR Supra 3.0?

• The light indicates the vehicle’s onboard diagnostics (OBD-II) detected a fault in emissions, engine, or drivetrain systems.
• Issues range from minor (loose gas cap, sensor drift) to serious (misfires, turbocharger or catalytic converter faults) that affect performance and emissions.
• Our techs use OEM-grade scanners to identify codes, explain options, and estimate repair costs so you see both immediate and long-term savings.
• If a repair is covered under warranty, it must be performed at a certified dealership to maintain coverage and ensure proper calibration with factory tools.

What is the most common reason for check engine light on a 2025 Toyota GR Supra 3.0?

• Common causes include sensor failures (oxygen sensor, mass airflow sensor), loose gas cap, or ignition/misfire events.
• The turbocharged inline-6 requires precise air/fuel control; sensors related to boost and emissions are frequent triggers if they drift or fail.
• Nalley Toyota Stonecrest’s diagnostics pinpoint root cause quickly, often saving money versus repeated independent visits and reducing long-term repair costs.
• Warranty-covered repairs must be performed at a certified dealership to protect benefits and ensure correct parts and calibration.

How long does a check engine light service take?

• Standard diagnostic scans typically take 30–60 minutes; follow-up repairs vary by issue and can range from a quick fix to multiple hours for parts replacement.
• Minor fixes like a gas cap or sensor swap are often same-day; more involved repairs, such as turbo or catalytic work, may take longer depending on parts availability.
• We prioritize clear timelines and use factory tools to complete work efficiently, often resulting in lower total ownership costs versus repeated independent attempts.
• Any warranty repairs must be done at a certified dealership to preserve coverage and ensure long-term reliability.
