The code for cat efficiency is P0420.
The codes your getting are for 02 sensor heating circuit failed
iether the 02 sensors have been damaged or not plugged in correct sockets, they are colour coded plugs grey and black.
they should screw in by hand then tighten to required torque. its best to use a tread tap or chaser to clean the threads up before inserting , 02 sensors are easily damaged if you apply heaps of force
