Well to start with you should have 3 O2 sensors on the rig. And if it has more then 100,000 miles on it ,it is a good idea to change all 3. As for the codes they can be caused by a vacuum leak check all of your lines and the vacuum canister, it should be in the inner fender passenger side. Follow the lines.
