P1B03: Understanding The Hybrid/Ev Battery System Fault
The P1B03 fault code is related to the drive motor position sensor. The motor control module monitors the position, speed, and direction of the drive motor rotor. The position sensor contains a drive coil, two driven coils, and an irregular-shaped metallic rotor.
The DTC is set when the motor control module is unable to track the motor position based upon the sensor signals. The drive motor 1 position sensor is serviceable separately from the drive motor assembly.
