Drive Motor Phase V Current Malfunction
The P0A60 code indicates a problem with the phase V current in the drive motor of a hybrid or electric vehicle. This typically means the motor control module has detected an abnormal current reading in one of the three phases (U, V, W) of the electric motor. This can be caused by a faulty motor, inverter, wiring issues, or a malfunctioning control module.
