OS2 Heater Circuit?

Hello,
I have a 96 SL320 with 133k on it. The MIL came on just as I pulled in the driveway tonight on my way home from happy hour. I took out my scanner and up came the code P0141. "Current for Oxygen sensor heater is outside the limit (approx 0.2-2.0 A) for longer than 2 secs. I am confused as it says OS2 heater circuit malfunction. Do I replace the OS2? Do these things have heaters in them? Any ideas? Thanks for your help!
Brian
