Rear ABS light always on. What can cause and how to fix?

Checked rear sensor and cleaned connectors, still stays lit. If I replace the sensor, do I need a code reader to reset the rABS light?

First thing you need to do is to read the codes and find out which circuit is causing the indicator to come on.
Let us know the codes.
For codes clearing it depends on whether you vehile is 2 wheel or 2 wheel ABS system. For 2 wheel type, no resetting is necessary. 4 wheel system requires a scan tool or special manual erasing procedures.
