Check Engine Light Flashing

A flashing check engine light on a 2018 Ford F-250 Super Duty is an urgent indicator of active misfire or other conditions that can damage the catalytic converter if you continue driving. When the light flashes, it often means the engine is skipping combustion cycles or running lean/ rich in a way that produces excessive heat at the converter. At Larry H. Miller Ford Lakewood in Lakewood, CO, we advise pulling over safely and contacting our service center for guidance. Our certified technicians prioritize flashing-light diagnostics and will assess engine codes with Ford-grade tools to determine whether immediate towing or on-site intervention is necessary. Because delayed action can multiply repair costs, bringing your truck to a factory-certified service center quickly often saves you money and prevents collateral damage. We highlight any applicable service specials and can arrange service financing so you can get repairs completed without delay.

2018 Ford F-250 Super Duty Check Engine Light Codes

The most common codes for a 2018 Ford F-250 Super Duty include P0171/P0174 (fuel trim/lean), P0300-P0308 (cylinder misfires), P0420 (catalyst efficiency), and various sensor-related codes like P0130-P0167 (oxygen/HEGO sensors).
