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.

Likely causes

Loose or corroded supply or ground terminal at charger B
Ground offset between charger B and the reference module
Fluctuating 12 V network from weak battery or DC/DC converter
Faulty supply voltage measurement inside charger B

Symptoms

  • Plug-in charging starts late, pauses or stops
  • Fault appears with electrical load changes or vibration
  • Charging system warning in the instrument cluster
