Current Sensor
WARNING: This page is about a different car, the 2015 Hyundai Sonata. However, it is still accessible from the selected car via links, so may be relevant.
The current sensor detects the electric current flowing to the motor and is used to control the current phase flowing into the motor from the motor controller. The sensors for the motor and for the HSG are different, and the current sensor is internally connected to the power module.
