You can have as many as 4 O2 sensors in your system, depending on the engine type. If you changed the wrong 2 sensors, the problem has not been repaired.

Also - make sure to check the power feed to the heated sensors. No power to the heaters will also generate codes.

The CMP code indicates a problem with the cam position sensor.

As a side note, with this number of codes, I would be more inclined to look for problems with the wire harness. You may have a spot rubbed through on other metal parts. Also check connectors from the sensors back to the processor. Also check your ground points. A bad ground can also generate "phantom" fault codes.
