Manufacturer-specific interpretations

Ford

3 interpretations
P2125:16
APP E circuit continuity Ford · engine Data confidence 94%

Ford documents P2125:16 (circuit voltage below threshold) for its 2024-2025 gasoline-engine OBD monitor strategy as app e circuit continuity. 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

Frequently asked questions about P2125

What does P2125 mean?

Diagnostic Trouble Code (3 variants). The control module detected improper operation of the Accelerator pedal position (APP) / Throttle position (TP) sensor/switch E circuit.

Is P2125 generic or manufacturer-specific?

P2125 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 P2125 at file level?

If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry. Checksum correction is not included: it is a separate, optional service. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
