Ok Im sure this will better help me find out what I need.
I scanned my car and its reading that the Bank#2 Sensor#1 is no good.
Now which O2 sensor is the one I need to replace, Ive marked them A,B,C,D..make sure you pay attention to the line directing each sensor to the port.

Thanks

 

sensor 1 = front sensor
Bank 2 = sensor on bank with cylinder #2

IIRC it's B, but it's been 2 years since I needed one.

 

So you say its B?

 

same one thats bad on my max! lol

 

So is it B?

 

went bad on my i30.
replaced it but the code came back. never did get to the bottom of it. sold the car with a coolant loss problem for $1200.

 

I just wanna know if the one I need to change is B if not then which one would it be. Thats all I care to know.

 

Bank 2 is with the even cylinder numbers ie 2,4,6.

Bank 2 is closest to the front of the car.
As for sensor 1, i'd guess the first sensor on that bank. I'm assuming you have a cali spec since you have so many o2 sensors.

I'd double check that you do have a cali spec vehicle. If you dont then that will throw off which one it can be. You can use the stickies to decypher your vin to find out if its cali or not.

 

well then...

 

I have a cali spec

 

before the catalytic.

 

ok thanks

 

Hey this is the sensor I need to replace as well. Does anyone know where I can find the picture that the OP was reffering to?

 

I would think that it would be possible to disconnect the suspected o2 sensor then start the car and see if the new code that you get refers to the same location or not.
