Standardized SAE J2012 code · P2Exx codes
What does P2E27 mean?
The phase X, Y, and Z current sensors of drive motor A do not correlate within the calibrated tolerance. Sum of phase currents should be near zero.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
