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.

Likely causes

DC/DC converter regulating the 12 V network too high
External battery charger or jump starter with excessive voltage
Faulty voltage measurement inside the charger module

Symptoms

  • Plug-in charging stops or will not start
  • Overvoltage faults stored in other modules as well
  • Lamps unusually bright or 12 V battery overcharged
