Check Engine Light Flashing

The check engine light flashing on a 2021 Ford Transit indicates a potentially serious condition — often a misfire that can damage the catalytic converter or a critical electrical fault. When the light flashes, stop driving safely as soon as possible and have the vehicle inspected. At Larry H. Miller Ford Lincoln Draper in Draper, UT, our technicians prioritize flashing lights and offer full charging system and battery inspections alongside code reading to isolate the root cause. We test battery voltage, starter draw, alternator output, and related sensors so you receive a targeted repair plan rather than guesswork. Our facility uses OEM parts and manufacturer‑approved procedures to protect longevity and emissions systems. If repairs are needed, we explain immediate and long‑term savings — fixing a misfire early prevents expensive downstream damage. Ask about current service specials and our service financing to make urgent repairs affordable. For critical flashing lights, call us or schedule service online now to limit damage and restore safe operation.

2021 Ford Transit Check Engine Light Codes

Common check engine light codes on the 2021 Ford Transit include P0420 (catalyst system efficiency), P0300 (random/multiple misfires), P0130–P0171 (oxygen sensor and fuel trim issues), and electrical/charging related codes that can point to battery or alternator faults. Left unaddressed, these conditions can escalate: a P0300 misfire can ruin a catalytic converter, resulting in repair bills that exceed preventive maintenance costs; failing oxygen sensors hurt fuel economy and increase emissions; and charging system faults can leave you stranded or damage vehicle electronics. At Larry H. Miller Ford Lincoln Draper our certified technicians diagnose codes with OEM-grade scanners, perform battery and charging tests, and present clear estimates that emphasize how early repair saves money. We maintain transparency, honor warranties for covered repairs (performed at certified dealerships), and use OEM parts for reliable outcomes.

2021 Ford Transit Check Engine Light Reset
