P2C6FDrive Motor A Phase Z 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
P2C6F is the general current fault for phase Z, the third phase of the second winding set of drive motor A. No manufacturer documents it publicly. Whether Z is measured at all depends on the design: the Mitsubishi Electric patent fits a sensor to each of X, Y and Z, while a Hyundai patent describes inverters that measure two phase currents and calculate the third, since all three must add up to zero. In the second case a Z code can arise from an error in X or Y, so the other phases must be checked too. The code covers implausible readings and current that does not follow the command without a clear low or high case (P2C70, P2C71); a sensor circuit fault is P2E23. The driver sees a hybrid or drive warning with reduced or no electric power.
What you may notice
  • Hybrid or drive system warning with MIL
  • Reduced electric power, possibly engine-only operation on hybrids
  • Other X/Y phase codes stored alongside
Likely causes
  • PossibleError in the X or Y current measurement corrupting a calculated Z value
  • PossiblePhase Z terminal or busbar loose, corroded or overheated
  • PossibleFault in the Z switching leg or its gate driver
  • RareDamaged phase Z winding
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
