Battery Current Sensor

WARNING: This page is about a different car, the 2013 Lincoln MKX and 2013 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

The battery current sensor is attached to the negative battery cable. The BCM supplies a 5-volt reference and ground to the battery current sensor. The battery current sensor is a Hall-effect sensor that supplies a Pulse-Width Modulation (PWM) feedback signal to the BCM.
