can someone explain this code to me?

i was driving to work this morning and my check engine light came...took my car into a parts store hooked up the code reader...P0135...can any one tell me what this code means and what i need to do to fix the problem?

o2 sensor heater circuit malfunction (bank no. 1 sensor no. 1)

broken primary o2 sensor, bascially

so if i replace the sensor that should fix the problem?
