P2E3C code meaning
Battery Charger B Output Current Performance
What P2E3C means
P2E3C means charger B does not deliver the high-voltage current it has been asked for. No manufacturer documents P2E3C publicly. Its A-side model P0D22 is well covered: the 2011 Volt compares actual and desired current in constant-current mode against a table and sets the code after 150 bad samples in 300, One Trip Type A. Mitsubishi's 2022 Outlander PHEV stops charging if target and actual current differ by 3 A or more for 3 s while the PHEV-ECU permits charging. GM bulletins PIP4884B (2011 Volt, mostly in cold weather) and PIP5077D (2013 Volt) trace a MIL with P0D22 after charging to calibration and order a reflash of the hybrid powertrain control module 2, not a new charger. Voltage faults are P2E3A/P2E3B, a shorted output P2E3D. Charging slows or stops.
P2E3C 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 P2E3C
- MIL after or during charging
- Charging takes noticeably longer or aborts
- Problem more frequent in cold weather
Common causes of P2E3C
- Most likelyControl software or calibration of charger or hybrid module
- PossibleWeak power stage inside charger B
- Less likelyInaccurate output current measurement
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E3C means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 3C | The exact fault in that area. |
What to do next
- Note P2E3C 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 P2E3C
What does P2E3C mean?
P2E3C means "Battery Charger B Output Current Performance". P2E3C means charger B does not deliver the high-voltage current it has been asked for. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E3C?
P2E3C does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2E3C fail an emissions test?
P2E3C 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 P2E3C to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P2E3C clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
