Mine is located on the exhaust manifold, driver's side near the fire wall.

Disconnecting the O2 sensor for the short term won't hurt anything but may cause the EEC computer stay in close loop mode which may mask the problem, if it is cause by another sensor.  The motor will run rich and over time harm the catalyic converter, or so I was told.


You mean the EEC will stay in OPEN loop... The missing o2 sensor will be made up by backup programming in the EEC, which is likely more accurate than info from a 150k mi sensor. Yes it will go a little rich, but not enough to harm the converter. It's likely been dead for the last 40 or 50K mi anyway.
