SOURCE: auto shop advosed that the eldorado's compter

I show that your car uses one sensor located in the exhaust crossover of the exhaust head pipes off the engine, here is the part number and prive, labor time just to change the sensor is 1/2 hour plus the diagnostic time to test the system and determine the sensor was the problem,
ACDELCO Part # AFS73 Price $74.00 so $650 is way hight in my opinion.

Ok, bank 2 sensor 1 is the front one upstream sensor.--------- It's between the engine and the fire wall. it's pre catalitic converter. There is very little room. It's best to see and work on from drivers side fender.
----------------
Bank 2 Sensor 1 is on the driver side - follow the right side of the engine down the headers which attaches to the catalytic converter. The o2 Sensor you're asking about (Bank 2 Sensor 1) is before the Catalytic. The o2 Sensor after the Catalytic is Bank 2 Sensor 2. Bank 1 Sensor 1 is on the passenger side as well as Bank 1 Sensor 2.---------- --------- Approx cost for sensor only is near to 40$ and for replacing service charge by the mechanic will be more.--------The total cost will be under $100.------ To order the sensor, click the link below:-- http://technoanswers.blogspot.com/2011/08/o2-sensor-for-cadillac-seville.html --------- This should help.Thanks.Helpmech.

1998 Infiniti I30 trouble code P0134 were are the oxygen sensors?


code p 0134 refers to heated oxygen sensor(HO2S) 1 bank 1--no activity detected ===causes ---wiring open circuit--heating inoperative---HO2S sensor
it also refers to oxygen sensor (O2S) 1 bank 1 --no activity===causes wiring -- oxygen sensor
HEATED oxygen sensors are in the exhaust manifold or exhaust pipe before the cat converter
oxygen sensors are in the exhaust pipe after the cat converter
bank one is the side closest to the radiator on a cross fitted engine or on the lhs with you facing the fan

What is the best way to remove O2 sensor bank 1 sensor 2?


Here is the low-down on oxygen sensors, and their location designations explained:

Oxygen sensors are screwed into the exhaust system at various points. Some people say that there are 4 oxygen sensors, but technically, that is not correct. Only the front 2 are considered oxygen sensors.

These oxygen sensors are screwed into the exhaust pipe or directly into the exhaust manifold, one on each bank. Because they are in front of the catalytic converter, this is often referred to as 'upstream'.

The other 2 are actually called catalyst monitors. They are oxygen sensors, but they serve a different purpose. They monitor the activities of the catalytic converters, thus the name, catalyst monitors. They are screwed into the exhaust one on each bank, after, or downstream, of the catalytic converters.

On a 4 cyl engine, there are only a total of two such sensors, the one in front of the catalytic converter is the O2 sensor, the one behind the cat is the catalyst monitor.

The location names for them are as follows:
  • On a 4 cyl, the front / upstream is called "bank 1 sensor 1" and the rear / downstream sensor is called "bank 1, sensor 2."

  • On a V6 or V8 engine:

    • the passenger side bank on a forward facing engine, or the bank closest to the firewall on a transverse mounted engine, is bank number 1, so the forward / upstream sensor on that bank would be "bank 1, sensor 1."

    • The driver's side bank (forward facing mount engine), or front bank (transverse engine) would be bank number 2, thus the forward / upstream sensor on that bank would be "bank 2, sensor 1," and the rearmost / downstream sensor on that bank would be "bank 2, sensor 2."

Bank 1 sensor 2 location on a 1996 chevy suburban

Fig. Fig. 3: Oxygen sensor-4.3L engines

Fig. Fig. 4: Oxygen sensor-5.0L and 5.7L engines

Fig. Fig. 5: Oxygen sensor-7.4L engines




Oxygen sensors are always numbered like this:
Bank 1 sensor 1
Bank 2 sensor 1
Bank 1 sensor 2
Bank 2 sensor 2

Some manufacturers use a kind of shorthand that reads different, but means the same thing:
Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2

Bank 1 is always the side of the engine where cylinder number 1 is located and, of coarse, Bank 2 is the opposite side.
On a 4 cylinder engine, there is only 1 bank and it is always referred to as Bank 1.

Sensor 1 is always the upstream sensor (the one located BEFORE the catalytic converter)
Sensor 2 is always the downstream sensor (the one that is located AFTER the catalytic converter.

Hope helps (remember to rate this).

O2 Sensor on a 1996 Cadillac Eldorado


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!
