2021 Ford Transit Passenger Van Check Engine Light Codes

In Lakewood, CO, at Larry H. Miller Ford Lakewood we see common engine codes on the 2021 Ford Transit Passenger Van that point to predictable causes and costs when left unaddressed. Frequent codes include P0420 (catalytic converter efficiency), P0171/P0174 (fuel trim/lean condition), P0300 series (misfires), and oxygen sensor faults. Ignoring a P0420 can lead to failed emissions tests and catalytic damage that may cost thousands to repair; early diagnosis prevents escalation and preserves resale value. Lean condition codes (P0171/P0174) often reduce fuel economy and stress engine components, increasing long-term maintenance costs. Misfires (P0300+) can damage the catalytic converter and cause loss of power or stalling, a safety risk if unattended. At Larry H. Miller Ford Lakewood, our certified techs use OEM diagnostic tools to identify the exact cause, provide a clear estimate, and recommend solutions that favor longevity and efficiency. We often cost less than independent shops for comparable work because of our streamlined parts access, warranty coverage, and diagnostic accuracy. Schedule online to minimize downtime: schedule service, and check current service specials before your visit.
