P0E92Drive Motor B Inverter Voltage Sensor B Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
- What you may notice
- MIL and hybrid or EV system warning
- Second drive motor switched off, reduced acceleration
- Likely causes
- PossibleVoltage channel B of the motor B inverter drifts
- PossibleInternal fault of the motor B inverter or motor unit
- RareWrong comparison value from battery management or the front power electronics
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
