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!

If you're apprehensive about doing this work, buy a Haynes repair manual (about $20), It shows you how to remove the manifold

What to the codes P2270 mean on my Cadillac


It's the O2 sensor attached to your exhaust pipe behind the catalytic convertor that has detected your exhaust is too lean. It could mean any of a variety of issues from simply the sensor is faulty, to the sensor being loose fitting, to a leak in the exhaust before the sensor, to a bad fuel injector ---- essentially, anything that can reduce the amount of fuel emission that "should" be present.

Why does my 2000 Cadillac escalade smoke from the tail pype but the smoke is black


Black smoke usually means a very 'rich' mixture....but because this is run by the computer, it really means that the computer is being sent a message that there is a 'lean' mixture and it is trying to fix this. So, problem might be vacuum leak or O2 sensor.

Trying to remove an o2 sensor that befor the cat off 200 caddy escalade


To remove the O2 sensor you will need an O2 sensor socket that you can buy at most auto part stores, or you can dis-connect the wire connector for that O2 sensor, and then slip the wire connector from the O2 sensor through a 7/8 inch box end wrench and then slide the wrench up to the O2 sensor and then remove the O2 sensor. Use plenty of W-D40 to soak the base of the O2 sensor before removing it, and if the wire connector does not fit through the box end of the wrench then cut the wire connector off from the O2 sensor, and you will only need the open end of the wrench to install the O2 sensor, and only tighten the O2 sensor up until you feel the the sealing rings crush down, and do not over-tighten the O2 sensor because they are not supposed to be torqued down.
