Check THIS Before Condemning an ABS Module - 08 Dodge Challenger

This 2008 Dodge Charger kept throwing a right rear ABS speed sensor "no signal" fault — even after the sensor was replaced. The wiring checked out. The resistance tested fine. But the ABS module was still providing low supply voltage with the sensor plugged in. This is an active wheel speed sensor or Magneto-resistive sensor.
