P0E26 is logged when the signal of inverter temperature sensor G climbs above its permitted range. In the 2023 Outlander PHEV it belongs to the front motor unit's U-phase H2 sensor: at least 3.75 V lasting 0.08 s, with at least 8 V supply to the unit, sets P0E26-00 together with MIL and hybrid warning light. With an NTC element and pull-up resistor, the layout GM documents for its inverter thermistors, such a voltage would mean an extremely cold power switch, which a working inverter never shows; the usual reasons are an open sensing line, a lost reference ground or a broken thermistor. The low-side fault is P0E25. Because the sensor is built into the unit, Mitsubishi replaces the power drive unit.

Likely causes

Open sensing line or broken thermistor

Lost sensor reference ground

Signal shorted to the sensor supply

Symptoms

MIL and hybrid warning light on
Reduced electric drive power as a precaution
