Pulled Engine Codes,Know What is it, Need help Fixing

[off-road97Xplor]

Hi, my check engine light has been on for awhile and I pulled the code like 2 minutes. Came up with " O2 Sensor Circuit Slow Response" ( Bank 2 Sensor 1)
Where is this sensor locatated and is it hard to fix? I dont think Oxy Sensors would cause any long term harm.
Thanx,

It's the oxygen sensor on the left side closest to the exhaust manifold.

This code IS usually caused a dying O2 sensor... the rapidity with which it "crosses over" the .445 volt "ideal" does not happen as rapidly as it should during a cycle test (not the right name, but you get the idea, somewhere in a drive cycle the computer actually varies the fuel mixture and watches what the 02 sensor does.).
