P0D82 code meaning
Battery Charger Input Circuit Low
What P0D82 means
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.

- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor1 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0D82
- Charging does not start
- Charging ends earlier than expected
- Charging fault message
Common causes of P0D82
- PossibleInput sense line or harness shorted to ground
- PossibleMoisture or corrosion at the charge inlet terminals
- PossibleFailed input stage inside the on-board charger
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D82 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 82 | The exact fault in that area. |
What to do next
- Note P0D82 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0D82
What does P0D82 mean?
P0D82 means "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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D82?
P0D82 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0D82 fail an emissions test?
P0D82 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0D82 to fix?
Difficulty: workshop only. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will P0D82 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
