What P0E23 means
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.
P0E23 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0E23
- Hybrid system warning light and MIL on
- Reduced electric drive power
Common causes of P0E23
- Most likelyTemperature sensor or sensing board inside the inverter failed
- PossiblePoor contact at an internal or external inverter connector
- Less likelyFaulty evaluation input in the motor control unit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E23 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 23 | The exact fault in that area. |
What to do next
- Note P0E23 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0E23
What does P0E23 mean?
P0E23 means "Drive Motor Inverter Temperature Sensor G Circuit". 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 is a generic code, so it means the same on every make.
Is it safe to drive with P0E23?
Drive gently and only to a workshop. With P0E23 the car can go into limp mode (reduced power) to protect itself.
Will P0E23 fail an emissions test?
Yes, it can. P0E23 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0E23 to fix?
Difficulty: workshop only. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P0E23 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
