Generic (OBD-II) interpretation

P2800
Transmission Range Sensor "B" Circuit (PRNDL Input) Generic · transmission Data confidence 78%

The control module detected a fault associated with the Transmission Range Sensor "B" Circuit (PRNDL Input) circuit or function; the stored code identifies the affected component rather than a single failure mode.

Manufacturer-specific interpretations

Ford

4 interpretations
P2800:01
TRS B General electrical fault Ford · transmission Data confidence 94%

Ford documents P2800:01 for its 2024-2025 gasoline-engine OBD monitor strategy as trs b general electrical fault. 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
  • Compare commanded and measured values
  • Check applicable OEM service information

Frequently asked questions about P2800

What does P2800 mean?

Diagnostic Trouble Code (4 variants). The control module detected a fault associated with the Transmission Range Sensor "B" Circuit (PRNDL Input) circuit or function; the stored code identifies the affected component rather than a single failure mode.

Is P2800 generic or manufacturer-specific?

P2800 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 P2800 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.
