P2C6EDrive Motor A Phase Y Current 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
- P2C6E reports that too much current flows in the Y phase of drive motor A, which sits in the machine's second winding set. No manufacturer documents P2C6E publicly. A Hyundai bulletin shows what usually lies behind a phase overcurrent: on the 2017 Ioniq Hybrid, coolant leaking inside the traction motor set the high codes of phases U, V and W (P0A5F, P0A62, P0A65), often with the isolation fault P0AA6. Dealers ran an insulation breakdown test and replaced the motor if it failed, and drivers noticed weak acceleration and no air conditioning. The same applies to Y: moisture, coolant or damaged insulation lets current bypass the intended path. A shorted inverter switch or a sensor reading too high are the other suspects. P2C6D is the low side, P2C6B and P2C71 are X and Z.
- What you may notice
- Hybrid warning and MIL, often with an isolation fault code
- Weak acceleration or electric drive switched off
- Electric air conditioning compressor disabled
- Likely causes
- PossibleCoolant or moisture inside the motor degrading winding insulation
- PossibleShort between phase Y and another phase or the stator core
- PossibleShorted power switch in the Y leg of the inverter
- RarePhase Y current sensor reading too high
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
