2 interpretationsFord documents P08B4:11 (circuit short to ground) for its 2024-2025 gasoline-engine OBD monitor strategy as clutch pedal position sensor b circuit low. This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.
Recommended checks
- 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
