What P0E2B means
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.
P0E2B 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 P0E2B
- MIL and hybrid warning light on
- Drive power may be limited
Common causes of P0E2B
- Most likelyInterrupted signal path of sensor H
- PossibleMissing sensor ground
- Less likelyThermistor element gone open
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E2B means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 2B | The exact fault in that area. |
What to do next
- Note P0E2B 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 P0E2B
What does P0E2B mean?
P0E2B means "Drive Motor Inverter Temperature Sensor H Circuit High". P0E2B is the upper-limit fault of inverter temperature sensor H. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E2B?
Drive gently and only to a workshop. With P0E2B the car can go into limp mode (reduced power) to protect itself.
Will P0E2B fail an emissions test?
Yes, it can. P0E2B 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 P0E2B to fix?
Difficulty: workshop only. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P0E2B clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
