P2E26Drive Motor A Phase Z 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
- P2E26 reports a phase Z current sensor signal of drive motor A that sits above its permitted range. No manufacturer documents P2E26 publicly. The consequence goes beyond one lost reading: in GM's eAssist table the overcurrent check P0C01 and the missing-phase check P0C05 only run while no current sensor code is active, and current control falls back to a mode that ignores the sensors. The inverter therefore loses part of its own protection and has to hold back torque. GM's U-phase high limit there is 440 A, two-trip Type B. Causes on the measuring side include the signal touching the supply line or an interrupted ground return; true overcurrent in phase Z is P2C71. A Mitsubishi Electric patent names Z as the third phase of a separately controlled second set. Low side: P2E25.
- What you may notice
- Hybrid warning lamp and MIL
- Electric drive torque clearly reduced
- Vehicle continues only in a reduced-power mode
- Likely causes
- LikelyPhase Z signal shorted to the sensor supply
- PossibleOpen ground of the phase Z sensor
- PossiblePhase Z current sensor failed high
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
