Check Engine Light Flashing

A flashing check engine light on a 2016 Ford F-250 Super Duty typically signals an active misfire or condition severe enough to risk catalytic converter damage and compromised safety. When the light flashes, engine combustion is unstable and unburned fuel can overheat or destroy emission components. At David McDavid Ford in TX we treat a flashing light as an urgent concern: our factory-trained technicians perform a priority diagnostic to identify misfires, ignition faults, or fuel delivery problems. Acting quickly reduces repair scope and expense — delaying can double or triple costs if secondary parts fail. We use OEM ignition components, injectors, and sensors to ensure correct fit and long life. Ask about service financing to begin repairs immediately and spread the cost over time. Check for current rebates and {service specials} via our online offers, and schedule service to minimize downtime. For owners who value transparency, we provide itemized estimates and explain long-term savings from using OEM parts and dealership expertise.

2016 Ford F-250 Super Duty Check Engine Light Codes

Common codes for the 2016 Ford F-250 Super Duty include P0300 (random/multiple cylinder misfire), P0420 (catalytic converter efficiency), P0455 (large EVAP leak), P0171 (system too lean), and P0325 (knock sensor). Left unchecked, P0300 can lead to damaged pistons or catalytic converters; repairs can range from simple spark plug replacement to multi-thousand-dollar engine work. P0420 often starts as an oxygen sensor replacement ($200–$400) but can escalate to a catalytic converter replacement if ignored. EVAP leaks like P0455 are commonly inexpensive to repair but can trigger failed emissions tests and continued drivability warnings. At David McDavid Ford we provide clear cost estimates, OEM parts, and a recommended timeline to avoid cascading failures. Our service advisors can explain immediate and long-term savings, warranty implications, and options to schedule appointment or take advantage of service specials.
