P2E2E code meaning
Battery Charger A Module Supply Voltage High
What P2E2E means
P2E2E reports the opposite of P2E2D: the low-voltage feed of on-board charger A rises above its upper limit. On a plug-in vehicle the 12 V network is held by the DC/DC converter, so a converter regulating too high is the first suspect; an external charger or jump-start device at excessive voltage can do the same, and a faulty measurement inside the charger can fake the reading. Mitsubishi's Outlander PHEV, for comparison, treats charger supply voltages above 16 V as outside its test window for P0D67; P2E2E itself appears in no public manufacturer documentation, threshold included. Under CARB rules, a plug-in hybrid must flag charger faults that prevent or limit charging. Low is P2E2D, implausible P2E2C, system overvoltage P0563. Charging may stop to protect the electronics.
P2E2E 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 P2E2E
- Plug-in charging stops or will not start
- Overvoltage faults stored in other modules as well
- Lamps unusually bright or 12 V battery overcharged
Common causes of P2E2E
- Most likelyDC/DC converter regulating the 12 V network too high
- PossibleExternal battery charger or jump starter with excessive voltage
- 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 P2E2E means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 2E | The exact fault in that area. |
What to do next
- Note P2E2E 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 P2E2E
What does P2E2E mean?
P2E2E means "Battery Charger A Module Supply Voltage High". P2E2E reports the opposite of P2E2D: the low-voltage feed of on-board charger A rises above its upper limit. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E2E?
P2E2E does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2E2E fail an emissions test?
P2E2E 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 P2E2E to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2E2E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
