P2E2C code meaning
Battery Charger A Module Supply Voltage Performance
What P2E2C means
P2E2C covers the low-voltage supply that powers the control electronics of on-board charger A, not the AC input. The code means this supply voltage is present but behaves implausibly, for example it fluctuates or disagrees with what other modules see on the same 12 V network. Mitsubishi shows why the value matters: the Outlander PHEV only judges the charger's internal 3.3, 6 and 12 V rails while the charger supply is between 10 and 16 V. Mitsubishi files those faults under P0D67, and no maker documents P2E2C itself. CARB requires plug-in hybrids to detect charger faults that stop or slow charging. Out-of-range values are P2E2D and P2E2E, AC input voltage P0D27/P0D28, charger B P2E2F. Driving is normally unaffected, but charging can be refused or break off.
P2E2C at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2E2C
- Plug-in charging does not start or stops early
- Charging system warning message
- Fault comes and goes with electrical load or vibration
Common causes of P2E2C
- Most likelyLoose or corroded supply or ground connection at the charger
- PossibleGround offset between charger and other modules
- PossibleUnstable 12 V supply from weak battery or DC/DC converter
- Less likelyFaulty voltage measurement inside the charger module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E2C means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 2C | The exact fault in that area. |
What to do next
- Note P2E2C 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 P2E2C
What does P2E2C mean?
P2E2C means "Battery Charger A Module Supply Voltage Performance". P2E2C covers the low-voltage supply that powers the control electronics of on-board charger A, not the AC input. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E2C?
P2E2C does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2E2C fail an emissions test?
P2E2C 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 P2E2C to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2E2C clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
