Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 1
Generic · emissions
Data confidence90%
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.
EGT sensor circuit low (bank 1, sensor 1)
Ford · engine
Data confidence94%
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

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.
