Code P1E16 Chevrolet Description

The power inverter module, often referred to as the drive motor generator power inverter module, contains three motor control modules and the hybrid powertrain control module. Two of the motor control modules operate their respective drive motor generator based upon power inverter module commands. The third motor control module controls the auxiliary transmission fluid pump motor. Each motor control module utilizes a 5 V reference power supply for internal circuit needs. This fault is handled inside the power inverter module and no external circuits are involved. The motor control modules and the hybrid powertrain control module are part of the power inverter module and are not serviced separately.
