P0E2B is the upper-limit fault of inverter temperature sensor H. Mitsubishi documents it for the 2023 Outlander PHEV, where sensor H is IGBT sensor 8 at the V-phase H2 position of the front motor unit: a signal reaching 3.75 V for 0.08 s while the unit receives 8 V or more sets P0E2B-00, and the function list shows MIL and hybrid warning light for it. In an NTC circuit with pull-up, as GM uses in its inverters, the controller would read this as an implausibly cold phase, so the cause is almost always electrical: an interrupted signal path, a missing sensor ground or an element that has gone open. Its low-side partner is P0E2A, the U-phase counterpart P0E26. The repair at Mitsubishi is a new power drive unit.

Likely causes

Interrupted signal path of sensor H
Missing sensor ground
Thermistor element gone open

Symptoms

  • MIL and hybrid warning light on
  • Drive power may be limited
