P0E96DC/DC Converter Voltage Sensor C Circuit

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
How the car detects it
P0E96 opens the series for a third voltage measurement in a DC/DC converter, sensor C. It is the general circuit code, meant for a missing or electrically invalid signal; range, low, high and erratic faults of the same sensor follow from P0E97 to P0E9A. Where a converter has more than two voltage channels, for example input and output plus a redundant reading, C names the third. No manufacturer documents P0E96 or any sensor C code in public sources. For orientation, GM's 2025 engine tables (25OBDG03A) cover sensors A and B of a 12 V converter that supports engine auto-starts, with valid readings between 1 V and 28 V and Type B confirmation; FCA calls the first two channels voltage sensor 1 and 2. CARB asks for circuit faults of such inputs to be detected. Converter output may be cut back.
What you may notice
  • 12 V or converter warning, possibly with MIL
  • Start-stop or 12 V support restricted
Likely causes
  • PossibleMeasuring circuit for channel C inside the converter defective
  • PossibleLoose connector or damaged sensing lead
  • RareSoftware fault in the converter or its controller
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
