It mayjust be extremely dirty. I would spray the small wires in the meter (located in the engine side of the air cleaner housing) with carb cleaner (engine off). Also check the wires to make sure that they are ok.
And I just wanted to say Welcome To FTE. I think that you will find a whole lot of useful info here.
The codes that you are speaking of concern the Ho2 sensors that are right after the exhaust manifolds. Usually accompanied by o2 sensor slow to read codes means its time to replace the heated o2 sensor.
