the MAF test above just shows that it's working, not that it's working properly.
Same for the O2 sensor; just basic 'does the part exist' tests shown.
Are you trying to root out a problem you suspect is related to the parts?
I swapped mine and wife's MAF a while back to see if problems I was having would migrate to her = nope. Problem stayed on my car. I was having consistent lean code related problems on the post cat O2 sensors, and two days ago my fuel pump hard failed, so i suspect it was weak for a while and finally died i never got a chance to measure the pressure.
