P2E2EBattery Charger A Module Supply Voltage High
- Generic OBD-II code · Powertrain
- How the car detects it
- 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.
