2021 Ford Transit Passenger Van Check Engine Light Codes

In Draper, UT, at Larry H. Miller Ford Lincoln Draper we see a predictable set of trouble codes on the 2021 Ford Transit Passenger Van. Common codes include P0300 (random/multiple cylinder misfire), P0420 (catalyst system efficiency below threshold), P0455 (evaporative emission system large leak), and P0171 (system too lean). Ignoring a P0300 can escalate to severe engine damage and poor drivability, often resulting in higher fuel use and costly repairs; a misfire left unattended can damage pistons, coils, and the catalytic converter. P0420 may begin as an oxygen sensor issue but can ultimately mean replacement of an aged catalytic converter — a repair that can exceed $1,000. P0455 is often a simple fix like a cracked hose or loose gas cap, but unchecked evaporative leaks can cause failed emissions tests. We provide transparent cost estimates for each scenario and highlight the immediate and long-term savings from OEM parts and preventative care. Our Ford-certified technicians use factory diagnostic tools to interpret codes precisely, and our service advisors discuss repair options, warranties, and any available service specials. To minimize downtime and get a prioritized plan, schedule service online and take advantage of dealer expertise in Draper.

2021 Ford Transit Passenger Van Check Engine Light Reset

Resetting the check engine light on a 2021 Ford Transit Passenger Van can be done with an OBD-II scanner, but a reset alone doesn't fix underlying faults. At Larry H.

Transparency is central: if a simple reset is all that's needed, we'll tell you; if a part or repair is required, we'll walk you through options and expected outcomes.
