P0E28Drive Motor Inverter Temperature Sensor H Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Sensor H is the eighth temperature sensor of a drive motor inverter, and P0E28 is its general circuit code for an electrical fault without a more precise low, high or erratic finding. No manufacturer documents P0E28 publicly. Mitsubishi, whose 2023 Outlander PHEV is the documented user of the H series, calls the part FMCU IGBT temperature sensor 8 (V-phase H2) and files its faults under P0E29, P0E2A and P0E2B; the general circuit code is not listed. Which component carries letter H is up to each maker. CARB requires hybrid input components to be checked for interruptions and for readings outside their range. When the value is missing, the controller has to protect that phase by limiting torque; the sensor is part of the inverter assembly.
- What you may notice
- Hybrid warning light and MIL on
- Limited motor torque
- Likely causes
- LikelySensor H or its sensing board in the inverter failed
- PossibleConnector or internal wiring fault in the inverter
- RareEvaluation input of the motor control unit faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
