All new OEM O2 sensors

I have checked all powers & grounds. Even if you drive it, then check the monitors before shutting off, the monitors have not cleared.

2011 E-350 6.8L will not run Cat, EVAP, O2, & O2 heater monitors.

Customer has replaced all O2 sensors, all Cats, two reman Ford PCM's. Data appears OK, mode 6 indicatesO2 monitors $02/ $85, $02/$86, $06/$85, & $06/$86 are incomplete.

Any ideas?
