Ford
3 interpretationsFord documents U0608:16 (circuit voltage below threshold) for its 2024-2025 gasoline-engine OBD monitor strategy as throttle/pedal position sensor/switch "b" communication 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
Ford documents U0608:17 (circuit voltage above threshold) for its 2024-2025 gasoline-engine OBD monitor strategy as throttle/pedal position sensor/switch "b" communication circuit high. 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
Ford documents U0608:81 for its 2024-2025 gasoline-engine OBD monitor strategy as lost communication with throttle/pedal position sensor/switch "c". 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
- Verify battery voltage
- Check module power supplies and grounds
- Inspect network wiring and connectors
- Measure network resistance with power isolated
- Check applicable OEM service information

Frequently asked questions about U0608
What does U0608 mean?
Diagnostic Trouble Code (3 variants). The control module stopped receiving expected network messages from the Throttle/Pedal Position Sensor/Switch C node on the vehicle communication bus.
Is U0608 generic or manufacturer-specific?
U0608 exists both as a generic OBD-II code (same meaning on every make) and with 1 manufacturer-specific interpretation(s): Ford. Always read it in the context of your vehicle.
Can TuningBot remove U0608 at file level?
Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether U0608 is removable in your case.
