Is this the bank1 sensor 1 in the photos? I was expecting it to be higher up and more difficult to get to. If this is sensor2 then I have no idea where sensor1 is and will probably take in in to be replaced.



If sensor1 is somewhere above the shinier metal section on the left then I have no clue where it is.




Way back on the right and not very visible.




If this is it it does seam do-able.




Thi is where it plugs in on the left side.

There is one sensor BEFORE THE CAT CONVERTER and one AFTER THE CAT CONVERTER, FOR EACH SET OF 3 Cylindars. The sensor 1 is located just below where the three exhaust ports come into 1 larger port that then feeds into the cat converter. You are looking at bank 1 sensor 2.

If you are skinny enough, you can replace bank 1, sensor 1 without jacking up the car. I did it once that way, but would recommend putting the car on some jack stands.

I think the hardest part is disconnecting the electrical connector.

Sensor 1 is what they call PRE-CAT (sensor before the Catalytic converter). Sensor 2 is needless to say after CAT Converter. This is universal for all cars.
