Hello mrsalbert, my name is JShreader. Thank you for choosing fixya.com
Depending on which oxygen sensor you are looking for...there are several of them throughout the Exhaust System. I will start out by giving you a brief description of what and oxygen sensor is, and they're general purpose.
DESCRIPTION
Four Heated Oxygen Sensors (HO2S) are
mounted in the exhaust system where they monitor the oxygen content in
the exhaust stream. There is an oxygen sensor mounted in each exhaust
manifold and one on each end of the catalytic converter. the oxygen
sensor located in the front exhaust manifold is the Bank 2 Sensor 1
(Front) sensor. The oxygen sensor located in the rear exhaust manifold
is the Bank 1 Sensor 1 (Rear) sensor. The oxygen sensor located in the
Y-pipe ahead of the catalytic converter is the Bank 1 Sensor 2
(Pre-converter) sensor. The oxygen sensor located in the catalytic
converter outlet is the Bank 1 Sensor 3 (Post-converter) sensor.
OPERATION
An oxygen sensor acts like a battery because it creates its own signal
voltage once it reaches operating temperature. This voltage is produced
when the oxygen content in the exhaust stream is different than the
oxygen content in the atmosphere. A lean condition (high oxygen content
in exhaust) will produce a low voltage (near 0 volts) and a rich
condition (low oxygen content in exhaust) will produce a high voltage
(near one volt). The PCM provides a reference signal voltage (0.45
volt) and a ground to the sensor. The PCM reference voltage is
necessary because the oxygen sensors do not provide their own voltage
until they reach operating temperature.
HEATING ELEMENT
the oxygen sensors also incorporate a heating element inside of the
sensor housing. This heating element is energized with the ignition On
and allows the sensors to reach operating temperatures quickly. The PCM
can then use oxygen sensor information sooner after engine start-up.
PCM INPUTS
The PCM uses oxygen sensor information during Closed Loop operation to
constantly adjust fuel control to reduce exhaust emissions. Because the
oxygen sensors provide information sooner after engine start-up,
exhaust emissions are reduced. Faulty oxygen sensors will cause various
driveability conditions and will set a DTC.
That being said...I uploaded a .pdf for you of pictures showing the locations of ALL the oxygen Sensors on your Vehicle. You can download it by clicking HERE.
I hope this helps you. If you have any more questions or need any more diagrams, please don't hesitate to ask...Thanks again, JShreader!

what year?if its fuel injected its in the fuel tank.if its carb. feed its on the side of the block.

you have 4 o2 sensors on the new one 2 in front of catylitic converter and 2 after on the exhaust

Easiest way. Go to any auto store, Pep Boys etc, locate the book for the year of your car and write down the wire diagram.

It is located in the valley between the cylinders. You can loosen the throtle body, all the bolts holding the intake manifold and then lift the manifols just enough without disturbing the fuel rail to gain access from the lest side of the car to the right. This can be done with common tools and the gaskets on the manifold and TB can be reused if not damaged.
