6 interpretations
P0243:16
Turbocharger/Supercharger Wastegate Solenoid A Low Ford · engine Data confidence 94%

Ford documents P0243:16 (circuit voltage below threshold) for its 2024-2025 gasoline-engine OBD monitor strategy as turbocharger/supercharger wastegate solenoid a low. 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 P0243

What does P0243 mean?

Diagnostic Trouble Code (6 variants). The control module detected improper operation of the Turbocharger Wastegate Solenoid A.

Is P0243 generic or manufacturer-specific?

P0243 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 P0243 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.
