Yes there are three o2 sensors
Bank 1 in the exhaust manifold
Bank 2 in the exhaust manifold
One after the Catalytic Converter.
Not sure what you mean 'where is the best place to put it'? The scan tool tells you which one needs replacing by a P**** Code, or are you just replacing one for fun?

The o2 sensors are located in the exhaust pipe. The one you are looking for is the post cat sensor. The sensor furthest back in the pipe after the catalytic converter. Mar 19, 2007

You most likely have a blown Auxilliary Power Outlet fuse. (Happens all the time) The Auxilliary Power Outlet fuse also powers you Data Link Connector (DLC). If the DLC has no power, the computer scanner will not communicate with the engine computer. Check Fuse #7 (25 Amp) in the instrument panel fuse block. (See diagram)

You have an heated Oxygen sensor. 2 of the wires heat up the sensor and keep it at a certain temperature, it is turned on and off by the computer. The other 2 are use to send a very low voltage reading back to the computer to tell the computer if the engine is running rich or lean. I don't have a diagram to tell you which wire does what but you can get a manual and that should give you the information that you need and tell you how to trouble shoot it to tell if the sensor is bad or not, you may want to look for a wire laying on the exhaust, I have found wires burnt and lay on the metal.
