Yes, another question on O2

Yes, another question on O2
Changed all 4 O2 sensors, still getting the following codes.
P0141 O2 sensor heater circuit malfunction (bank 1,sensor 2)
Rear sensor heater LH bank - short/open circuit (NAS
and EU-3 only)
P0161 O2 sensor heater circuit malfunction (bank 2,sensor 2)
Rear sensor heater RH bank - short/open circuit (NAS
and EU-3 only)
P0134 O2 sensor circuit no activity detected (bank 1,sensor 1)
Front sensor LH bank open circuit
P0154 O2 sensor circuit no activity detected (bank 2,sensor 1)
Front sensor RH bank open circuit
I checked the fuse- no go.
Next I am going to check the following and correct as needed.
1. Power to the O2's
2. Ground
3. continuity from the sensor to the ecm
My question is "Has anyone had these 4 at the same time, if so what was the solution?" Second, any steps I am missing? Thanks, S-
