2017 Ford F-350 Super Duty Check Engine Light Codes

The 2017 Ford F-350 Super Duty commonly logs codes related to evaporative emissions (EVAP), oxygen sensors (O2), catalytic converter efficiency, and misfires. In Mesa, AZ, Larry H. Miller Ford Mesa routinely interprets these codes with OEM-grade tools to determine whether a simple fix — like replacing a gas cap or oxygen sensor — is all that’s needed, or whether deeper repairs are required. Ignoring codes that point to EVAP leaks can allow fuel vapors to escape and trigger failed emissions tests; unresolved O2 sensor issues reduce fuel economy and can damage the catalytic converter. Misfires risk long-term engine damage and reduced towing capability, which for an F-350 with a 21,000 lb towing capacity is critical. We provide transparent estimates showing immediate cost and the long-term savings of prompt repairs. Our certified technicians recommend the right solution—often less costly than repeated independent-shop attempts—backed by OEM parts and warranty protections. Before your visit, review our service specials and schedule service online for fast, reliable care.
