Fiabilidad del dato94%
Ford documents P2629:12 (circuit short to battery) for its 2024-2025 gasoline-engine OBD monitor strategy as o2 sensor positive current trim circuit high (bank 2, sensor 1). This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.
Comprobaciones recomendadas
Perform a full module scan
Review freeze-frame and occurrence data
Inspect relevant wiring and connectors
Check power supplies and grounds
Compare commanded and measured values
Check applicable OEM service information
