Bank 1 Sensor 2 is post cat sensor, the one after the cat.

p0141 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

Before you rush out and buy a new sensor, check the heater circuit (the two white wires on the sensor) is receiving 12V power from the vehicle when the engine is running. *edit* whilst you are under there, unplug the rear sensor and check the resistance of the sensor heater - measure the resistance across the white wires, should be a few 10-15ohms or so. It may quite possibly in this case be open circuit, so timwe for a new sensor.

It could be the sensor heater broken or could be the heater supply circuit faulty elsewhere.
