P2E2FBattery Charger B Module Supply Voltage Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- 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.
