What P0E92 means
P0E92 is stored when voltage sensor B of the drive motor B inverter gives a reading inside its electrical range that does not fit the other voltage values of the high-voltage system. No manufacturer documents P0E92 publicly. The closest published test is Mitsubishi's plausibility check P0DA4, written for the first voltage channel of the rear motor in the 2023 Outlander PHEV: with the boost converter off, the rear inverter voltage is compared with capacitor 1 and both capacitor 2 channels of the front unit, and a difference of 100 V or more to each of them for 0.2 s counts; the hints name the rear motor unit, battery management and the power drive unit. For drive motor A the same fault on sensor B is P0E8D. A drifting measurement or a wrong reference elsewhere are both possible, so all channels should be compared.
P0E92 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 6 hours
- Clears after repairAfter a drive cycle
Symptoms of P0E92
- MIL and hybrid or EV system warning
- Second drive motor switched off, reduced acceleration
Common causes of P0E92
- PossibleVoltage channel B of the motor B inverter drifts
- PossibleInternal fault of the motor B inverter or motor unit
- Less likelyWrong comparison value from battery management or the front power electronics
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E92 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 92 | The exact fault in that area. |
What to do next
- Note P0E92 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 P0E92
What does P0E92 mean?
P0E92 means "Drive Motor B Inverter Voltage Sensor B Circuit Range/Performance". P0E92 is stored when voltage sensor B of the drive motor B inverter gives a reading inside its electrical range that does not fit the other voltage values of the high-voltage system. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E92?
Drive gently and only to a workshop. With P0E92 the car can go into limp mode (reduced power) to protect itself.
Will P0E92 fail an emissions test?
Yes, it can. P0E92 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 P0E92 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 6 hours of work. This is a job for a workshop.
Will P0E92 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
