What is an Oxygen Sensor?

Would you be shocked if I said it’s a sensor to measure oxygen? Okay, but it’s a bit more than that. Cars have both upstream and downstream sensors (also known as O2 sensors). Upstream oxygen sensors are placed in front of the catalytic converter, and measure the amount of oxygen in the exhaust. The car’s computer then uses that data to determine the proper air to fuel ratio.Downstream oxygen sensors are located behind the catalytic converter, and measure the efficiency of the converter.

Signs of a faulty Oxygen Sensor

Poor performance

No one likes poor performance. That includes you, and it certainly includes your car. Faulty O2 sensors will feed misinformation to your car’s computer. The computer will then alter the engine in a way that leads to less power, some hesitation and jerkiness, and running rough. Which means you’ll be embarrassed the next time you try to show off at a green light.

Check engine light

Oh, the check engine warning light. That light that you pretend isn’t there when it lights up. How has that worked out for you? Try as you might, ignoring a check engine light won’t make it go away. And oxygen sensor failure is a common cause of the light illuminating.

How urgent is an Oxygen Sensor replacement?

You’re not really in any danger driving around with a busted O2 sensor. Your car will still be safe to drive. But the performance won’t be ideal, and you may fail an emissions test. You don’t need to drop everything and run straight to a repair, but get around to it when you can.

2006 BMW 325i - Oxygen/Air-Fuel Ratio Sensor

Your oxygen sensor, sometimes called an O2 sensor or air-fuel ratio sensor, measures the oxygen level in your exhaust gases. It then relays this information to the ECU to adjust the fuel mixture. If there is too much oxygen in the exhaust, the fuel mixture is too lean, but too little oxygen indicates a rich fuel mixture. If your exhaust sensor is working poorly, or not at all, you may notice a decrease in fuel efficiency, poor engine performance, stalling, hesitation, or a rough idle. The incorrect information being supplied to the ECU creates a poor fuel mixture, and your vehicle will perform poorly. If you have one or more bad oxygen sensors, O'Reilly Auto Parts carries replacement oxygen sensors for most cars, trucks, and SUVs.

I noticed when looking for o2 sensors from the online parts stores they list them as Front/Rear Oxygen Sensor - Left/Right OR Front/Rear Oxygen Sensor - Upper/Lower.
http://ebmwparts.com/parts/2008/BMW/...agramCallOut=4
http://www.ecstuning.com/BMW-E90-335...ine/Emissions/

I added an image showing the part numbers. If anyone can help me with the correlation between Front/Back;Upper/Lower & Bank X/Sensor X, I can update the image & we'll know how to interpret the sensor location for Error codes like;
"P22AA: Nox Sensor Heater Sense Circuit Intermittent (B1S2)"

For ordering parts we need to know, is "Bank X" referring to Front/Back, Left/Right or Upper/Lower? Then if it's referring to Front/Back, which one is "Bank 1"? Same goes for "Sensor X", is it referring to Left/Right, Front/Back or Upper/Lower & which one is "Sensor 1"? Then we'd need to know the correlation between Left/Right & Upper/Lower.

Here's what I think I know based on other threads.

Bank 1, Sensor 1 = cyl 1,2,3 - the most visible O2 sensor towards the front of the engine
Bank 2, Sensor 1 = cyl 4,5,6 - the one towards the rear of the engine, still visible by just opening the hood and peering inside
Bank 1, Sensor 2 = cyl 1,2,3 - under the engine (not sure where), never actually seen it.
Bank 2, Sensor 2 = cyl 4,5,6 - last O2 sensor before the long mid-pipe running under the vehicle.

My hunch is that Bank X is referring to Front/Rear & Sensor X is referring to Upper/Lower. Is that right?
If so, I'm guessing

Front, Upper = Bank 1, Sensor 1 (Number 6) (pre-cat) (PN: 11787558055)
Front, Lower = Bank 1, Sensor 2 (Number 7) (post-cat) (PN: 11787545074)
Rear, Upper = Bank 2, Sensor 1 (Number 8) (pre-cat) (PN: 11787558087)
Rear, Lower = Bank 2, Sensor 2 (Number 9) (post-cat) (PN: 11787545075)

Front = Bank 1
Rear = Bank 2
Upper = Sensor 1 (pre-cat)
Lower = Sensor 2 (post-cat)

Can anyone clarify this for sure? The 2nd image, I believe, is from another BMW fiche, not for the 335, but same idea.

Research on Oxygen Sensor for BMW 325i

It is common knowledge that your vehicle's engine is responsible for creating the energy that spins your wheels and propels your vehicle on the road. This energy is created through the combustion process. Air and fuel are channeled into each cylinder's combustion chamber where they are compressed and ignited. Many drivers fail to realize that the mixture within each cylinder's chamber must be carefully measured. The oxygen sensor (OS) plays a fundamental role in ensuring an optimum ratio between the air and fuel. All oxygen sensors including the 2008 BMW 328i o2 sensor and 2001 BMW 325i oxygen sensor are located within the exhaust stream.

Maintaining the Ideal Ratio

The ideal ratio between oxygen and fuel channeled in your engine's combustion chambers is 14.7 to 1. Very little will without doubt result to a rich mixture. In such cases, the combustion process results in unburned fuel flowing out of the combustion chamber right into the exhaust system. This results to pollution and will cause your vehicle to fail an emissions test.

Excess air in the combustion chamber causes a lean mixture. That generates excess nitrogen oxides, a dangerous pollutant. Not only does this overwork your car's catalytic converter, but it can also lead to engine damage. Maintaining the ideal ratio between air and fuel mixture requires constant monitoring and this is the fundamental role of the oxygen sensor.

When the Component Fails

An oxygen sensor is estimated to last up to 80,000 miles, but can fail earlier depending on your driving habits. If it fails, your car's computer will not be in a position to make adjustments to the ratio of air-fuel mixture used in your engine's combustion chambers. Consequently, the closed feedback loop that usually ensures the mixture is optimized opens. Your emissions rise, potentially causing your vehicle to fail an emissions test. Your gas mileage will fall as your engine becomes less efficient. You may also notice a decline in performance as the air-fuel mixture runs rich or lean. If your oxygen sensor fails, have an OEM-certified replacement installed as soon as possible. Otherwise, your engine may begin experiencing problems that will worsen with time.

BMW 325i Oxygen Sensor Replacement Cost

A 2001 BMW 325i oxygen sensor replacement will cost you between $532 to $691 if performed in Austin, Texas. Ensure that you address the cause of your sensor's failure when replacing it. It could be contamination with coolant or exhaust leaks or any other cause. Be sure to have it replaced it so as to adhere to emission guidelines.

Where is the oxygen sensor?

Newer vehicle models are now equipped with an oxygen sensor for each cylinder for a more efficient engine. Sensors are located in the exhaust stream underneath the car either at the front or back of the catalytic converter. A faulty oxygen sensor will cost you poor gas mileage and eventually your catalytic converter may get damaged.
