Check Engine Light Flashing

The sight of a flashing check engine light in your 2025 Ford Ranger is a clear signal to stop driving and seek immediate professional inspection.

At David McDavid Ford in TX, our service advisors and certified technicians prioritize safety and diagnostics: we run a full OEM diagnostic scan, inspect ignition and fuel systems, and evaluate charging and battery health to identify whether a failing battery, alternator, spark plug, fuel injector, or sensor is triggering the condition. Choosing dealer service provides documented procedures, OEM parts, and warranty protection where applicable; remember that warranty-covered repairs must be completed at a certified dealership. We also offer service financing and frequent service specials to reduce immediate costs.
