Check Engine Light Flashing

When the check engine light is flashing in a 2020 Toyota GR Supra, it usually indicates an active misfire or a condition that can damage the catalytic converter. A flashing signal is more urgent than a steady light: it can mean unburned fuel is reaching the exhaust and creating excessive heat, which threatens costly downstream components. At Larry H. Miller American Toyota Albuquerque we treat flashing lights as high priority. Our factory-trained technicians run a full diagnostic, inspect ignition coils, spark plugs, fuel delivery, and turbo systems specific to the GR Supra’s inline-six turbo setup. We use OEM parts and Toyota-approved procedures to repair faulty components and prevent collateral damage, delivering immediate reliability and longer-term value. Before you drive extensively, stop by and schedule service to protect performance. Check our latest service specials and ask about service financing so you can address urgent repairs right away while preserving warranty coverage and peace of mind.

2020 Toyota GR Supra Check Engine Light Reset

Miller American Toyota Albuquerque means transparent diagnostics, certified technicians, and documented repairs that protect factory warranties — repairs covered under warranty must be completed at a certified dealership to remain valid.
