The bank 2 sensor is located in the engine exhaust manifold/pipe behind the engine at the firewall.
Good luck.

SOURCE: o2 sensor

If you can't access it from from the engine compartment you will need to jack the car up and support it. You need a 7/8 box end wrench. Sometimes it take a special wrench due to the angle not accessable with a strait wrench. Its on the exhaust pipe in front of the cat

HOW DO YOU REPLACE THE BANK 1 SENSOR 1 IN 2002 OLDSMOBILE AURORA 4.0


The car must be on a lift as the sensors are under the car in the exhaust pipe. You want the cylinder bank 2 sensor but be advised it is not recommended that just one be replaced, as they may send confusing signals from old and new senor to the cars computer this may turn the check engine light back on. The sensors are "upstream" (before the catalytic converters) and "downstream" (after the catalytic converters) In order to know what you need I need to know the fault code you received.

Where is the 02 sensor number 3 located


That would be the oxygen sensor in back of the catalytic converter. Sensors 1 and 2 are in the exhaust near the engine, one on each side or bank of the engine, and number 3 sensor will be in the exhaust after the cat. The purpose of number 3 sensor is to monitor the efficiency of the catalytic converter.

How many oxygen sensors are in my 95 oldsmobile aurora? and where are they located?


LOCATIONS There are different locations in the exhaust system where O2S sensors are positioned. The locations have been given numbers and will be used in the accompanying charts to identify the positions of O2S sensors in most vehicles. Due to mid-year production changes or factory inconsistencies, all models may not be covered. If a vehicle being serviced is not covered in the charts, inspect the exhaust system (while cold!) in the general locations to find the applicable O2S sensors. NOTE: If equipped with dual exhaust systems, there may be up to 4 or 5 O2S sensors in the exhaust system. Be sure to locate all of them before commencing with any testing or service. Fig. 1: Location No. 1 — down pipe or exhaust manifold 79248g01.gif
Fig. 2: Location No. 1 — typical O2S sensor located in the exhaust manifold 79248g04.gif
Fig. 3: Location No. 2 — left and right banks of a V-type engine 79248g02.gif
Fig. 4: Location No. 3 — exhaust collector (where more than one pipe joins together) 79248g05.gif
Fig. 5: Location No. 4 — outlet of the catalytic converter 79248g06.gif
Fig. 6: Location No. 5 — inlet and outlet of the catalytic converter 79248g03.gif

Running lean?


Check for a vacuum leak. You can do this acouple ways the easyest way is too spray some brake clean around engine and if engine picks up you have a leak in that area.Thats the most common fault.

On my 97 Olds Aurora, I'm having trouble passing emissions. An oxygen sensor is malfunctioning, I have had my codes read and they say it's the bank 1 sensor 1. But I just replaced the very first oxygen...


The bank 1 sensor should be the one before the CAT on the side of the engine that includes cylinder #1. If you're not sure which bank that is, look across the heads from the side of the engine (front of the car) The bank with #1 on it will have the head a little (1"-2") more towards the front of the engine. The bank that has the head set back a bit will be #2. When there are sensors after the CAT, they're not oxygen sensors, they're CAT efficiency sensors.
