DTC 33 = Manifold Absolute Pressure (MAP) sensor circuit (signal voltage high, low vacuum)
How did you arrive at the conclusion you have an O2 sensor problem? The two are not related

the left bank reads low and doesnt "bounce" around like the right side. the right side goes from 0 to about 850 and the left stays around 430mv at idle and sometimes driving it might ease up to 720mv or so but mostly between 3??mv and 6??mv. i took the bosch out and put a new bosch in and it was the same way. so i took it out and went and got my money back and got a gm and its the same way. i gotta get this car right i got a$$es to whoop lol
