2 interpretations
P0033:16
Turbocharger/Supercharger Bypass Valve "A" Control Circuit Low Ford · engine Data confidence 94%

Ford documents P0033:16 (circuit voltage below threshold) for its 2024-2025 gasoline-engine OBD monitor strategy as turbocharger/supercharger bypass valve "a" control circuit 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
  • Inspect relevant wiring and connectors
  • Check power supplies and grounds
  • Compare commanded and measured values
  • Check applicable OEM service information
