In Braintree, MA, Herb Chambers Ford of Braintree treats flashing conditions as high priority—our certified technicians perform immediate diagnostics with OEM tools to isolate ignition coils, spark plugs, fuel injectors, or wiring faults that commonly cause misfires. Addressing a flashing light quickly saves money by preventing secondary damage; the long-term savings from timely repairs usually outweigh the initial diagnostic fee. We provide transparent estimates, OEM parts, and documented repairs that protect factory warranties because warranty work must be completed at a certified dealership. Take advantage of current service specials, and use our flexible service financing to get repairs now and pay over time.

2022 Ford Expedition Check Engine Light Codes

Common check engine light codes for the 2022 Ford Expedition include P0300-series misfire codes, P0420 catalytic efficiency codes, P0171/P0174 fuel trim codes, and oxygen sensor faults.
