Check Engine Light Flashing

A flashing check engine light in a 2023 Toyota GR Supra typically signals a severe condition such as engine misfire or catalytic converter risk. When the light flashes, unburned fuel may be entering the exhaust system, which can rapidly overheat and damage downstream components. At Larry H. Miller Toyota Murray in Murray, UT, our certified technicians prioritize flashing conditions and will perform an immediate diagnostic scan, targeted testing, and, when necessary, a controlled road evaluation to prevent collateral damage. We explain findings in plain language and recommend cost-effective, lasting solutions using genuine Toyota parts. Acting quickly with a trusted dealership not only resolves the immediate safety concern but also preserves performance and avoids major repair bills later. We encourage you to schedule service right away; if you want to take advantage of current discounts, review our service specials. Our service advisors can also discuss service financing so you can get urgent repairs now and pay over time.

2023 Toyota GR Supra Check Engine Light Reset

Resetting the check engine light on a 2023 Toyota GR Supra is more than clearing a code — it's about confirming the underlying fault is fixed. Our technicians at Larry H. Miller Toyota Murray use OEM diagnostic procedures to clear codes only after repairs are verified, ensuring the issue won't reoccur. Independent reset tools can erase a warning temporarily, but without a proper repair you risk recurring faults and possible warranty invalidation. We provide transparent estimates, OEM parts, and manufacturer-aligned repair documentation so warranty claims remain intact; any warranty-covered repair must be completed at a certified dealership to stay valid. Choosing our dealership often reduces overall ownership costs by preventing repeat visits and protecting vehicle value. Before we reset a light, we explain the cause, recommended repairs, and available incentives — visit our service specials or schedule appointment to get started.
