Code P1E4B Chevrolet Description

The drive motor generator position sensor is monitored by the motor control module. The motor control module monitors the angular position, speed and direction of the drive motor generator based upon the signals of the resolver-type position sensor. The position sensor allows the motor control module to determine the exact position, speed and direction of the drive motor generator. The hybrid powertrain control module also calculates motor speed. This fault is handled inside the power inverter module, often referred to as the drive motor generator power inverter module, and no external circuits are involved.
