P2E90Battery Charger A Internal Power Supply Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- 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.
