Manufacturer-specific interpretations

Ford

3 interpretations
P0115:16
(low input) Ford · engine Data confidence 94%

Ford documents P0115:16 (circuit voltage below threshold) for its 2024-2025 gasoline-engine OBD monitor strategy as (low input). 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

P0115:17
high input Ford · engine Data confidence 94%

Ford documents P0115:17 (circuit voltage above threshold) for its 2024-2025 gasoline-engine OBD monitor strategy as high input. This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.

Frequently asked questions about P0115

What does P0115 mean?

Diagnostic Trouble Code (3 variants). The control module detected improper operation of the Engine Coolant Temperature Sensor Circuit 1.

Is P0115 generic or manufacturer-specific?

P0115 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 P0115 at file level?

If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry and, where the ECU needs it, corrects the checksum too. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
