Next, do you know anybody with a similar car you could swap known-good sensors with? To answer your question directly, i believe the OBD codes don't give you enough information to differentiate which sensor (or sensor circuit --> wiring) is bad. Are you anywhere close to Track Dog or Rogue? They might have spare parts around to try.
