P0E94Drive Motor B Inverter Voltage Sensor B Circuit High
- 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
- P0E94 records that voltage sensor B in the drive motor B inverter reports a value at the top of its signal range. A short from the signal to a supply, an interrupted sensor ground or a defective measuring stage are the usual explanations; a genuine overvoltage would normally show on the other channels too. No manufacturer documents P0E94 publicly. For sensor A of the rear motor Mitsubishi publishes the high limit on the 2023 Outlander PHEV: P0DA6 needs a signal of at least 4.76 V lasting 0.3 s, and only while the propulsion system is active, so the check is not run in standby. The low side of sensor B on motor B is P0E93, the high side of sensor B on motor A is P0E8F. CARB requires out-of-range checks for such inputs. Expect the second motor to be taken offline and a warning with MIL.
- What you may notice
- MIL and EV system warning
- Second drive motor deactivated, less traction and power
- Likely causes
- LikelyMeasuring stage for channel B in the motor B inverter defective
- PossibleSignal shorted to a supply or lost sensor ground
- RareReal overvoltage on the high-voltage bus
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
