P2E22Drive Motor A Phase Y 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
- P2E22 is stored when the phase Y current sensor signal of drive motor A sticks above its upper limit. No manufacturer documents P2E22 publicly. On GM's 2016 Cadillac ELR the U/V/W counterparts fail above 800 A, judged as 4 bad samples out of 6 at 10.4 ms intervals, Type A. Notably, the V-phase checks only run while no U-phase sensor code is active, and W waits for V in the same way, presumably so that one shared fault does not set a code on every phase. If P2E22 shows up together with high codes of X or Z, look for such a common cause first, for example the sensor reference. On its own, a short between signal and supply line, or a lost sensor ground, is the likely culprit; real overcurrent in phase Y is P2C6E. Mitsubishi Electric's two-group motor patent lists a dedicated Y sensor beside those for X and Z. Low side: P2E21.
- What you may notice
- Hybrid warning lamp and MIL
- Electric drive switched off or strongly limited
- High codes of other phases stored at the same time
- Likely causes
- LikelyPhase Y signal shorted to the sensor supply
- PossibleOpen ground of the phase Y sensor
- PossibleShared sensor reference faulty, other phases affected too
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
