Clutch Pedal Position Sensor B Circuit/Open Generic · engine Data confidence 65%

The control module detected an interruption (open circuit) in the Clutch Pedal Position Sensor B circuit, so the expected electrical continuity was not present.

Manufacturer-specific interpretations

Ford

2 interpretations
P08B4:11
Clutch pedal position sensor B circuit low Ford · transmission Data confidence 94%

Ford 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
