P0D41 code meaning
Battery Charger A Input Voltage Sensor A Circuit Intermittent/Erratic
What P0D41 means
P0D41 is reserved for an input voltage sensor A signal at charger A that is intermittent or erratic, i.e. it jumps or drops out briefly. No manufacturer documents this code with set conditions; GM and Mitsubishi only use P0D3E-P0D40 for this sensor. GM's information bulletin 12-08-45-001A shows how unstable household supplies appear in practice: electrical noise on the AC line can disturb charging on the Volt, ELR and Spark EV, sometimes together with P0D3F or P0D3E. CARB's rules for input components cover such signal faults in general. Possible causes are poor contacts between inlet and charger, a degrading sensor in the charger, or a noisy supply. Charging may stop and restart unpredictably; driving continues.
P0D41 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0D41
- Charging stops and restarts unpredictably
- Fault appears only at one charging location
Common causes of P0D41
- PossibleElectrical noise or poor grounding on the AC supply
- PossibleLoose contact between charge inlet and charger
- Less likelyVoltage measurement in the charger degrading
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D41 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 41 | The exact fault in that area. |
What to do next
- Note P0D41 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 P0D41
What does P0D41 mean?
P0D41 means "Battery Charger A Input Voltage Sensor A Circuit Intermittent/Erratic". P0D41 is reserved for an input voltage sensor A signal at charger A that is intermittent or erratic, i.e. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D41?
P0D41 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0D41 fail an emissions test?
P0D41 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 P0D41 to fix?
Difficulty: medium. A typical repair takes 0.3 to 4 hours of work. This is a job for a workshop.
Will P0D41 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
