Generic (OBD-II) interpretation

P0544
Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 1 Generic · emissions Data confidence 90%

The control module detected a fault associated with the Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 1 circuit or function; the stored code identifies the affected component rather than a single failure mode.

Possible causes

  • Wiring
  • EGRT sensor
  • ECM

3 interpretations
P0544:16
EGT sensor circuit low (bank 1, sensor 1) Ford · engine Data confidence 94%

Ford documents P0544:16 (circuit voltage below threshold) for its 2024-2025 gasoline-engine OBD monitor strategy as egt sensor circuit low (bank 1, sensor 1). 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

P0544:17
EGT sensor circuit high (bank 1, sensor 1) Ford · engine Data confidence 94%

Ford documents P0544:17 (circuit voltage above threshold) for its 2024-2025 gasoline-engine OBD monitor strategy as egt sensor circuit high (bank 1, sensor 1). This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.

Frequently asked questions about P0544

What does P0544 mean?

Diagnostic Trouble Code (3 variants). The control module detected a fault associated with the Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 1 circuit or function; the stored code identifies the affected component rather than a single failure mode.

Is P0544 generic or manufacturer-specific?

P0544 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 P0544 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.
