P2E1DDrive Motor A Phase X Current Sensor Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2E1D says the phase X current sensor signal of drive motor A lies below its lowest valid value. Phase current flows in both directions, so the sensor reports a signed quantity; low therefore means a reading more negative than any real current, not a weak current. That other case, too little current in an energised phase, is P2C6A. No manufacturer documents P2E1D publicly. GM's U-phase counterpart on the 2016 Volt trips below -700 A for 0.05 s within a 0.1 s window, Type A, MIL after one trip. Such a value points to the measuring path: a signal shorted to ground, a lost sensor supply or a failed sensor inside the inverter. Where such a sensor sits is shown in a Mitsubishi Electric patent: on the lead from the inverter to the X winding. Expect a hybrid warning and reduced drive. High side: P2E1E.
- What you may notice
- Hybrid warning lamp and MIL
- Sharp loss of electric drive power
- Vehicle may only drive in a reduced mode
- Likely causes
- LikelySensor signal shorted to ground inside the inverter
- PossibleSupply voltage of the phase X sensor missing
- PossiblePhase X current sensor failed
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
