Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
Some 2021-2023 Bronco Sport vehicles may exhibit an illuminated MIL with diagnostic trouble codes (DTCs) P025A, P025B, P00C6, P008A, P0627 and/or U0109 stored in the powertrain control module (PCM). This may be due to an intermittent or partial disconnect of the harness, connector pin push-outs or loose/corroded grounds to the fuel pump control module (FPCM) connector, PCM connector and/or battery junction box connector. Inspect the following connectors for 1.5L and 2.0L engines: C1551B, C1035A, C110, C401, C4033, C4330. Verify the connections are fully seated, without damage and/or pushed out pins/terminals prior to performing Workshop Manual (WSM) diagnostics or replacing any components. Inspect G404 and verify it's clean and secure. If any connector damage is found, repair as necessary. Refer to Wiring Diagram, Cell 005.

Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
