P0D50 code meaning
Battery Charger Hybrid/EV Battery Output Voltage Sensor Circuit Intermittent/Erratic
What P0D50 means
P0D50 stands for an unsteady output voltage signal from the on-board charger: the value jumps or drops out briefly instead of following the slowly changing battery voltage. No manufacturer documents P0D50 publicly. GM and Mitsubishi only publish fixed limits for this sensor (P0D4E, P0D4F) and, at GM, a comparison with the battery voltage (P0D4D), so a dedicated check for signal spikes would be an additional layer. CARB lets such checks count as part of the circuit and rationality monitoring it requires for the plug-in charger. Loose internal contacts, failing solder joints or interference within the charger are the likely triggers. Charging may stop and restart repeatedly; driving is unaffected.
P0D50 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 P0D50
- Charging repeatedly interrupted
- Charge time noticeably longer than usual
- Sporadic charging system warning
Common causes of P0D50
- Most likelyLoose contact or cracked solder joint in the charger's measuring path
- PossibleElectrical interference from the charger's power stage
- PossibleAgeing voltage sensing electronics in 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 P0D50 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 50 | The exact fault in that area. |
What to do next
- Note P0D50 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 P0D50
What does P0D50 mean?
P0D50 means "Battery Charger Hybrid/EV Battery Output Voltage Sensor Circuit Intermittent/Erratic". P0D50 stands for an unsteady output voltage signal from the on-board charger: the value jumps or drops out briefly instead of following the slowly changing battery voltage. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D50?
P0D50 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0D50 fail an emissions test?
P0D50 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 P0D50 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P0D50 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
