P2E90 code meaning
Battery Charger A Internal Power Supply Performance
What P2E90 means
P2E90 says the internal power supply of charger A, the rails that feed its control and gate-driver electronics, does not behave as intended. Kia uses the code: technical bulletin ELE409 (service action SA639, December 2025) covers 2025 EV6 and 2026 EV9 built between 21 February and 18 September 2025 that store P2E9092, performance or incorrect operation, and can no longer charge on Level 1 or 2; the fix is a new integrated charging control unit (ICCU). Mitsubishi watches the same rails under P0D67 on the Outlander PHEV: 3.3, 6 and 12 V supplies must stay in their windows for 1 s, otherwise charging stops. TI explains that such bias supplies draw on the 12 V or high-voltage battery. Charger B is P2E91; the 12 V feed of the module itself is P2E2C.
P2E90 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor1 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2E90
- No AC charging at home or on Level 2 stations
- DC fast charging may still work
- Charging system warning in the cluster
Common causes of P2E90
- Most likelyInternal supply stage of charger A or the ICCU failed
- PossibleWeak 12 V feed or loose low-voltage connector at the charger
- Less likelyCharger software fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E90 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 90 | The exact fault in that area. |
What to do next
- Note P2E90 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 P2E90
What does P2E90 mean?
P2E90 means "Battery Charger A Internal Power Supply Performance". P2E90 says the internal power supply of charger A, the rails that feed its control and gate-driver electronics, does not behave as intended. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E90?
P2E90 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2E90 fail an emissions test?
P2E90 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 P2E90 to fix?
Difficulty: workshop only. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P2E90 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
