bank one is on the driver side, sensor 2 is after the convertor...left side low...if its a heater code, make sure the fuse is ok.

No fuse. 99% of the time this means replace the 02 sensor. Check the wiring to make sure it is not damaged also. Could be a bad connection.

underhood fuse block o2 sensor2 (post) fuse 62. this fuse is for the 02 heater supply circuit.
most of the time the wiring rubs through on the frame and blows the fuse.

you changed the wrong sensor. when referring to left and right for cars, left is from the perspective of sitting in the drivers seat.
you need to change b1s2 its the driver's side rear sensor.

If you change the bad sensors, have you cleared the codes and seen if its fixed?
