P2E1EDrive Motor A Phase X Current Sensor Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2E1E flags a phase X current sensor signal of drive motor A above the top of its valid range. No manufacturer documents P2E1E publicly. GM's U-phase counterpart on the 2016 Volt trips above 700 A for 0.05 s within 0.1 s, Type A. The same table stops real overcurrent at 600 A through P0C01, and Ford's 2019 hybrids treat more than 600 A for 400 microseconds as motor overcurrent. The sensor limit thus lies beyond any current the inverter would tolerate, so a reading that high almost always comes from the measuring side, for instance a signal shorted to the sensor supply or an open sensor ground. Genuine excess current in phase X is P2C6B. The inverter limits or stops drive. Low side: P2E1D.
- What you may notice
- Hybrid warning lamp and MIL
- Electric drive cut off or strongly limited
- Possible jolt when the inverter shuts down
- Likely causes
- LikelySensor signal shorted to the sensor supply
- PossibleOpen ground of the phase X current sensor
- PossiblePhase X current sensor failed high
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
