Hi!
The description of your code means that the computer isn't seeing a change in voltage with your downstream bank 2 oxygen sensor. This sensor "sees" the amount of oxygen in the exhaust and makes changes to the fuel curves and injector pulsewidth to give you the best air/ fuel mixture. This code means that either the sensor is dead or there is an open in the signal wire to the computer.
