P0E2A reports that inverter temperature sensor H delivers a voltage below its lower limit. Mitsubishi's 2023 Outlander PHEV assigns the code to IGBT sensor 8 (V-phase H2) of the front motor control unit, triggered by a voltage at or under 1.25 V lasting 0.08 s while the supply is 8 V or higher; the MIL comes on. Sensor 8 is the last one with a generic code there: for sensors 9 to 12 Mitsubishi falls back on its own P301x codes, since the generic list stops at H. If the circuit is an NTC divider of the type GM documents, low voltage reads as excessive heat, so a ground short makes the inverter look overheated and power is cut back. Genuine phase overheating is a separate code; the high-side fault is P0E2B.

Likely causes

Signal of sensor H shorted to ground
Shorted thermistor element
Moisture or coolant damage on the sensing board

Symptoms

  • MIL and hybrid warning light on
  • Power reduction similar to an overheating inverter
