P1E4A – Control Module Redundant Drive Motor 1 Speed Sensing Circuit

P1E4A Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

P1E4A Possible Causes

Program Power Inverter Module,Faulty Power Inverter Module,Power Inverter Module harness is open or shorted,Power Inverter Module circuit poor electrical connection

P1E4A 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.
