So I got a CEL on my 06 TL yesterday. Took it to Auto Zone and came back with P2243 showing oxygen sensor bank 1 sensor 1. Anyone know where the exact location of this sensor is so I can go ahead replace it myself? Maybe there's a diagram somewhere you guys may know of. Also, a friend told me I should go with Denso over Bosch?

 

I think bank 1, senor 1 is the top O2 sensor on the front converter, but I am not really sure about that. Someone else will need to confirm.

 

Would this be whats circled on the diagram (#11)?
The ticket that Auto Zone gave me also states Rear AF sensor 11 vcent line high voltage..

 

The O2 sensors are #9, #10, #11, & #13.

Parts list is here: http://www.acuraautomotiveparts.org/...s=&view=normal


Again, I'm not sure exactly which sensor you have a problem with.


I *think* the top/upper sensor is sensor 1 and I *think* the front bank is bank 1.

The post-cat sensors (#11 & #13) include brakets/clamps in the parts diagram.

 

anyone else with an idea of where exactly this sensor is?

 

Did you ever fix this problem yourself? I pulled the same code and want to start this project!

Thanks

 

Bank 1 is rear, bank where #1 cylinder is located, sensor #1 is top or upstream sensor.

 

Hey guys im new to this forum, I just picked up a 2004 TL. I got these three codes all corresponding to the same location first of all are they related to one sensor or is there different sensors i need to buy. My second question is that it says bank 2 sensor 2 for all three locations does anyone have a video or diagram as to where this sensor(s) are located.

 

^if bank 1 is rear....that would mean bank2 is front!
if sensor 1 is upstream...sensor 2 is down stream....

I pulled all this info from the poster ABOVE you!!!!!!
be sure to read!

there's four(4) 02 sensors all together.
2 on bank 1
2 on bank 2

 

Always tells it like it is!

 

I received code P2237 which is oxygen sensor bank 1 sensor 1. I have read that it is good to change out your oxygen sensors in pairs. Is that correct? If so, does that mean I should also change out oxygen sensor bank 2 sensor 1? Also, could you help me with the locations? Is bank 1 sensor 1 (#10) and bank 2 sensor 1 (#9)? Any additional information would be helpful as I am fairly a noob at working on my car or any car for that matter.
Thank you for your help,
Stephen

 

Some folks will suggest to you to change them in pairs, some other folks, me included, will suggest to change them when they fail. Why? In my experience, an old, but still operational, O2 has about the same probability of lasting another 50,000 miles as does a brand new one.
