P2C6CDrive Motor A Phase Y Current
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2C6C is the umbrella code for the current in phase Y of drive motor A, the middle phase of the second X/Y/Z winding set. No manufacturer documents it publicly. Ford's 2019 hybrid summary explains what such phase current codes collect: the inverter is watched for overcurrent, current sensor faults and current regulation faults, and the result is stored per phase. For Y that means the measured current does not follow the command, or the reading cannot be trusted, without being clearly low (P2C6D) or high (P2C6E). A failed sensor circuit has its own code, P2E1F. CARB leaves the drive motor monitoring plan to each manufacturer, so thresholds differ. In practice look at the Y phase lead, its terminals and the inverter, and expect a warning and reduced or no electric drive.
- What you may notice
- Hybrid or drive warning, MIL on
- Reduced electric torque or jerky drive
- Vehicle not ready to drive in severe cases
- Likely causes
- LikelyInverter cannot regulate the phase Y current to its command (control or gate drive fault)
- PossibleLoose, corroded or overheated phase Y terminal at inverter or motor
- PossiblePhase Y current reading implausible against the other two phases
- RarePartial winding fault in phase Y of the motor
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
