The sensor is located in the driver's side exhaust manifold, the heater element is used to get the sensor operating up to temperature quickly. Once up to temperature, it should read normally but will still set a code.

Generally a good idea to get only an AC/Delco OEM replacement. You can get them fairly cheap at these sources:

Shoebox also has the part #s and rough pricing (+ shipping):

Its a bit easier to get the old sensor out with an "O2 sensor socket"..... a tall socket with a large slot in the side so it will fit over the wire.
