Check Engine Light Flashing

A flashing check engine light on your 2023 Ford Mustang signals an active misfire or condition that can quickly damage the catalytic converter and other engine systems. When you see a flashing light, pull over safely and limit further driving; prolonged operation under these conditions increases repair costs and can lead to permanent component failure. At Coggin Deland Ford in Deland, FL, our service team responds swiftly with priority diagnostics to determine if the issue is an ignition component, fuel delivery problem, or sensor failure. We use OEM-grade parts and factory software updates to ensure the repair is correct and durable. Choosing dealership service often delivers immediate savings by addressing root causes correctly the first time, and long-term savings by preserving engine health and resale value. We also honor warranties and document repairs, which maintains coverage integrity—repairs under warranty must be completed at a certified dealership like ours. To protect your vehicle and avoid escalating costs, schedule service online or review our current service specials before visiting, and ask about service financing if you prefer convenient payment options.

2023 Ford Mustang Check Engine Light Reset

Resetting the check engine light on a 2023 Ford Mustang may clear the lamp temporarily, but without diagnosing and repairing the underlying issue the light will likely return—and you risk masking a problem that affects performance and emissions. At Coggin Deland Ford we explain why a reset alone is not sufficient: our factory-trained technicians read trouble codes with OEM equipment, confirm pending or stored faults, and recommend appropriate repairs. Dealer service delivers transparency—detailed estimates, OEM parts, and documented results—so you understand immediate costs and long-term benefits. Using correct parts and software keeps your Mustang running efficiently and helps maintain warranty protection; remember, warranty repairs must be performed at a certified dealership. We also provide convenience through online scheduling, quick turnarounds, and rotating discounts found in our service specials. If you need service now and prefer flexible payment, we offer service financing to split the cost into manageable payments. To ensure your 2023 Ford Mustang is fixed right and to avoid repeat visits, schedule appointment with Coggin Deland Ford today.

2023 Ford Mustang Check Engine Light Codes

Understanding common check engine light codes for a 2023 Ford Mustang helps you evaluate urgency and potential costs. Some frequent codes include oxygen sensor failures (affecting fuel economy and emissions), misfire codes (which can harm the catalytic converter if left unaddressed), and EVAP system faults like a loose gas cap (low cost if caught early). At Coggin Deland Ford in Deland, FL, our technicians read and interpret codes immediately, explain the likely causes, and provide a clear estimate for repairs and parts. Ignoring codes can lead to more costly repairs—what starts as a sensor replacement can become an exhaust system or engine repair if delayed. By choosing our dealership you get the benefit of certified diagnostics, OEM parts for reliability, and technician expertise that reduces long-term ownership costs. We often provide better overall value than independent shops because our accurate diagnostics and correct repairs prevent recurring problems. Check our current service specials, consider service financing if needed, and schedule service to address codes promptly and keep your 2023 Ford Mustang performing at its best.
