2018 Ford F-250 Super Duty Check Engine Light Codes

Common check engine light codes for the 2018 Ford F-250 Super Duty include P0420 (catalytic converter efficiency), P0300 series (misfires), P0171/P0174 (lean fuel condition), and sensor-related codes such as P0130–P0167 for oxygen sensors. Each of these codes has cost implications: unresolved misfires (P0300) can damage pistons and catalytic converters, raising repair bills significantly; a P0420 left unchecked often leads to catalytic converter replacement, which is far more expensive than early sensor or exhaust repairs. A persistent lean condition can indicate vacuum leaks or fuel delivery issues that reduce fuel economy and accelerate wear. At Coggin Deland Ford in DeLand, FL, we diagnose codes quickly, present cost-effective repair plans, and handle warranty-covered items per manufacturer requirements. Choosing the dealership often costs less than independent shops when you factor in diagnostic accuracy, OEM parts lifespan, technician training, and long-term reliability—delivering immediate and ongoing savings.
