P2E2F code meaning
Battery Charger B Module Supply Voltage Performance
What P2E2F means
P2E2F concerns the 12 V feed of the control electronics in a second on-board charger, charger B, not its grid input. The voltage is within limits but behaves implausibly, for example it jumps around or disagrees with the system voltage that other modules report. No manufacturer documents P2E2F publicly. The A-side pages from Mitsubishi show why the feed matters: the Outlander PHEV runs its charger checks, such as P0D67 on the internal 3.3/6/12 V rails or the ROM test P0E5E, only while the charger supply sits between 10 and 16 V. A supplier unit like Holley's 30-8405 specifies the same 9–16 V working range. CARB wants plug-in hybrids to catch charger faults that stop or slow charging. Out-of-range values are P2E30/P2E31; the A twin is P2E2C. Charging may become unreliable.
P2E2F 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 P2E2F
- Plug-in charging starts late, pauses or stops
- Fault appears with electrical load changes or vibration
- Charging system warning in the instrument cluster
Common causes of P2E2F
- Most likelyLoose or corroded supply or ground terminal at charger B
- PossibleGround offset between charger B and the reference module
- PossibleFluctuating 12 V network from weak battery or DC/DC converter
- Less likelyFaulty supply voltage measurement inside charger B
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E2F means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 2F | The exact fault in that area. |
What to do next
- Note P2E2F 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 P2E2F
What does P2E2F mean?
P2E2F means "Battery Charger B Module Supply Voltage Performance". P2E2F concerns the 12 V feed of the control electronics in a second on-board charger, charger B, not its grid input. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E2F?
P2E2F does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2E2F fail an emissions test?
P2E2F 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 P2E2F to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2E2F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
