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!
SOURCE: Overheating
Many items need assessment. First what is THE COOLANT LEVEL enine running from cold start. IF LOW . Is there a coolant leak and where ? Lets say all of the previous check OK. ARE THE COOLING FANS OPERATING ? . They are , GREAT. Is it possible the cooling system ( i.e. radiator ) is clogged internally, or blocked exterior cooling fins of the radiator restricting cooling air. Hope this helps.

you have 4 o2 sensors on the new one 2 in front of catylitic converter and 2 after on the exhaust
SOURCE: camshaft position sensor
The camshaft position sensor is on the rear cylinder head on the left end (the serpentine belt end of the engine - passenger side). It is a son-of-a gun to get at. When it is bad or the connector is intermittant or bad, the symptom will be irregular idle from 500 to 750 RPM or so.
