P0E23Drive Motor Inverter Temperature Sensor G 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
- P0E23 is the catch-all circuit code of drive motor inverter temperature sensor G, a thermistor that watches the power switches of the motor inverter. It stands for an electrical fault the controller cannot pin down as low, high or erratic. No manufacturer documents P0E23 publicly. The only published user of the G series is Mitsubishi: in the 2023 Outlander PHEV the seventh IGBT sensor of the front motor unit (U-phase H2) reports its faults as P0E24, P0E25 and P0E26, but not as P0E23. CARB requires hybrid input components to be tested for open circuits and out-of-range signals. Without a valid temperature the inverter is usually run with reduced torque; the sensor sits inside the inverter, so repair often means that assembly.
- What you may notice
- Hybrid system warning light and MIL on
- Reduced electric drive power
- Likely causes
- LikelyTemperature sensor or sensing board inside the inverter failed
- PossiblePoor contact at an internal or external inverter connector
- RareFaulty evaluation input in the motor control unit
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
