Clear the codes and see if they return..

Put new O2 sensors in and see what happens.

in the last few weeks ive had two D2s throw O2 codes and it ended up being a bad connection in the grey multiplug under the hood on the passenger side back by the firewall. should be just behind the coolant reservoir.
