P0D47 code meaning
Battery Charger 14 Volt Output Current Sensor Circuit
What P0D47 means
P0D47 is the general circuit code for the current sensor in the charger's 14 V output, the measurement of how much current the charger's internal low-voltage stage delivers. No manufacturer publishes this code; GM's Volt and ELR charger module measures the same current but reports only low and high readings (P0D49, P0D4A), with 54 A as its upper limit. Range and sporadic faults have the codes P0D48 and P0D4B. The Ford patent on a DC/DC stage housed in the charger describes such a unit feeding the 12 V bus whenever the car is connected to a charging station. Under CARB rules every input of this kind must be checked for circuit faults. Without a valid current value the charger cannot limit its auxiliary output, so it may switch that stage off.
P0D47 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0D47
- 12 V battery discharges during long charging sessions
- Charging may be interrupted
Common causes of P0D47
- PossibleOpen or shorted current sense circuit of the low-voltage stage
- PossibleFailed on-board charger electronics
- Less likelyDamaged 12 V output connector at the charger
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D47 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 47 | The exact fault in that area. |
What to do next
- Note P0D47 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 P0D47
What does P0D47 mean?
P0D47 means "Battery Charger 14 Volt Output Current Sensor Circuit". P0D47 is the general circuit code for the current sensor in the charger's 14 V output, the measurement of how much current the charger's internal low-voltage stage delivers. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D47?
P0D47 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0D47 fail an emissions test?
P0D47 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 P0D47 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P0D47 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
