P0D82 Battery Charger Input Circuit Low

P0D82 reports that the charger's input circuit signal has dropped below the lowest value the module accepts as electrically valid. No manufacturer documents this code publicly; Ford, for instance, folds missing input into P0D80 with its 85 VAC/30 s limit. By analogy with other circuit-low codes, the cause is usually in the measuring path: a sense line shorted to ground, moisture or corrosion at the inlet terminals, or a failed input stage inside the charger. That separates P0D82 from P0D27, which judges a real but weak mains supply, and from P0D3F, which is reserved for the input voltage sensor circuit itself. CARB asks for such circuit faults on charger inputs to be detected. To the driver the result is a charge that will not begin or ends early.

Likely causes

Input sense line or harness shorted to ground
Moisture or corrosion at the charge inlet terminals
Failed input stage inside the on-board charger

Symptoms

  • Charging does not start
  • Charging ends earlier than expected
  • Charging fault message
