4 interpretations
P0120:01
Throttle/Pedal Position Sensor/Switch "A" Circuit Ford · engine Data confidence 94%

Ford documents P0120:01 for its 2024-2025 gasoline-engine OBD monitor strategy as throttle/pedal position sensor/switch "a" circuit. 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
Applies to Ford gasoline-engine OBD applications|2024-2025 model years
P0120:16
TP A circuit continuity Ford · engine Data confidence 94%

Ford documents P0120:16 (circuit voltage below threshold) for its 2024-2025 gasoline-engine OBD monitor strategy as tp a 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

Frequently asked questions about P0120

What does P0120 mean?

Diagnostic Trouble Code (4 variants). The control module detected improper operation of the Throttle Pedal Position Sensor/Switch A circuit.

Is P0120 generic or manufacturer-specific?

P0120 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 P0120 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.
