P2E25Drive Motor A Phase Z 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
- P2E25 means the phase Z current sensor of drive motor A reports below its valid minimum. No manufacturer documents P2E25 publicly. A zero reading is not the same thing: if phase Z carries no current because a lead is open, the sensor correctly reads about zero and the open phase is judged by P2C70. Low here means beyond the negative end of the scale; GM places that limit for its U/V/W sensors between -440 A on eAssist and -800 A on the 2016 Cadillac ELR. When X and Y log low codes as well, a common cause such as the shared sensor reference or a ground in the inverter's low-voltage wiring is more likely than three failed sensors; Ford, for one, watches that reference separately. High side: P2E26.
- What you may notice
- Hybrid warning lamp and MIL
- Reduced electric drive
- Low codes of other phases possibly stored too
- Likely causes
- LikelyPhase Z sensor signal shorted to ground
- PossibleShared sensor reference or ground faulty
- PossiblePhase Z current sensor failed
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
