P0E25 means the voltage of inverter temperature sensor G has fallen below its valid window. In the 2023 Outlander PHEV, Mitsubishi assigns it to the U-phase H2 sensor of the front motor control unit and sets P0E25-00 once that signal does not rise above 1.25 V during 0.08 s with a unit supply of 8 V upward; the MIL is switched on together with the hybrid warning lamp. Mitsubishi states only the voltage. For an NTC element fed through a pull-up resistor, as GM describes for its inverter sensors, a low voltage equals a very hot sensor, so a ground short or a damaged sensing line looks like an overheated switch. Real overheating is reported by separate temperature codes. The opposite limit is P0E26; the sensor is not sold separately.

Likely causes

Sensor signal shorted to ground inside the inverter

Thermistor internally shorted

Damaged sensing board, e.g. after coolant ingress

Symptoms

MIL and hybrid warning light on
Motor power limited as if the inverter were overheating
