Hi I had a P0140 and a P0141. Bought a new 02 sensor for Bank 1 sensor 2 downstream and fixed it. Now its displaying P0135 for that 02 sensor. I had extra 02 sensors from the box and swapped it twice still the same code.

That code indicates that the heater circuit for that O2 sensor isn’t functioning.

Check if the fuse has blown for the heater circuit for that sensor.

My Jeep Liberty 04 doesn’t have a fuse for 02 Sensors. They are controlled by the PCM. Is there any other option I can use.
