TuningBot DTC Database · v4.37.15
Generic (OBD-II) interpretation + 1 manufacturer-specific in the TuningBot DTC database.
FordThe control module detected a fault associated with the Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation circuit or function; the stored code identifies the affected component rather than a single failure mode.
FordFord documents P2138:00 (no sub type information) for its 2024-2025 gasoline-engine OBD monitor strategy as app d/e circuit disagreement. This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.
Ford documents P2138:48 for its 2024-2025 gasoline-engine OBD monitor strategy as internal control module accelerator pedal position voltage correlation (sensor 1 vs sensor 2). This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.
Powertrain: engine, transmission and driveline systems.
Generic SAE-standard code: same meaning on every make.
Specific fault index within the subsystem.
Diagnostic Trouble Code (2 variants). The control module detected a fault associated with the Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation circuit or function; the stored code identifies the affected component rather than a single failure mode.
P2138 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.
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.
