P0E93Drive Motor B Inverter Voltage Sensor B Circuit Low
- 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
- With P0E93 the controller sees the B voltage channel in the motor B inverter stuck near the bottom of its signal range, as happens with a short to ground, an open signal path or a failed measuring circuit. No manufacturer documents P0E93 publicly. Mitsubishi's rear motor sensor A on the 2023 Outlander PHEV gives a comparable limit: its low code P0DA5 sets once the signal sits at or below 0.55 V for 0.3 s with the rear motor unit powered at 8 V or more, and the checks start with the battery management and the high-voltage cables to the rear motor before the motor unit itself. Drive motor A has the equivalent sensor B fault as P0E8E. If several channels read low together, missing high voltage is more likely than a sensor fault. Motor B is normally disabled until the reading is valid.
- What you may notice
- MIL and EV system warning
- Rear or second motor without power, front-drive only
- Likely causes
- LikelyMeasuring circuit for channel B in the motor B inverter failed
- PossibleSignal line shorted to ground or open
- RareHigh-voltage cable or connection to motor B open, no voltage at the inverter
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
