2023 Toyota GR Supra 2.0 Check Engine Light Flashing

A flashing check engine light in your 2023 Toyota GR Supra 2.0 usually signals an active misfire or other condition that can quickly harm the catalytic converter and engine if driven. Misfires allow unburned fuel to enter the exhaust, raising temperatures that damage emissions components and multiply repair costs. If you see a flashing light, stop driving when safe and have the vehicle towed to Toyota of Greenville—driving further risks severe, expensive damage. Our factory-trained technicians prioritize these inspections, use OEM parts, and document findings for warranty claims. Choosing our dealership often results in immediate and long-term savings versus independent shops thanks to accurate diagnostics, correct repairs, and preserved warranty coverage.

2023 Toyota GR Supra 2.0 Check Engine Light Reset

Resetting a check engine light on a 2023 Toyota GR Supra 2.0 can be done with an OBD-II scanner or by clearing codes, but a reset without addressing the root cause can mask problems and lead to failed emissions tests or further damage. At Toyota of Greenville we recommend a complete diagnostic and repair before any reset; our factory-trained technicians confirm repairs with OEM tools, perform required drive cycles, and ensure systems are functioning properly. Repairs covered by warranty must be completed at a certified dealership to maintain coverage. By opting for dealership service you often save money immediately through accurate fixes and avoid costly repeat repairs, securing long-term value and reliability.

2023 Toyota GR Supra 2.0 Check Engine Light Codes

The 2023 Toyota GR Supra 2.0 most frequently returns codes such as misfire codes (P0300–P0304), fuel trim or lean-condition codes (P0171/P0174), O2 sensor faults (P0130–P0167), catalyst efficiency codes (P0420), and turbo-related underboost codes (P0299).

Prompt diagnosis at Toyota of Greenville prevents secondary damage and preserves performance. Our transparent estimates, OEM parts, and certified technicians often cost less than independent shops over time by avoiding repeated failures and ensuring warranty compliance for covered repairs.
