Volvo: Volvo S60 Fault Code # P0032, volvo s60, generic code

Question
Hi - I have the check engine light on and the Diagnostic tool shows Code P0032, Heat O2 Sensor Control Cricuit high B1, S2. Found O2 Sensor defective.
Does this mean my O2 sensor is defective? Websites show that there is Front and Rear sensors, how do I know which one is bad. ALso is it easy to replace this on my own?

Answer
Jai,
Try a scan tool that will read the codes in the Manufactures language.
You have a generic code and it is not real specific as to the faults.
However I usually always replace both HO2S because if one is new and one is old, I have then posted a code for a slow responding sensor. The sensors are simple to replace, however there are sometimes tight ares to work in.
