I just had to remove all of the same stuff to replace my leaking valve covers just a couple of months ago. I did not want to do that again. The ecu is looking for a small voltage between a set range to decide if that is normal and won't throw a code as long as it sees that voltage for each sensor. So I decided that since there are 2 sensors, and only one is bad right now, I will just feed both sensors from the good #1 bank sensor and the ecu will be happy. So i cut the wire feeding the #2 sensor and spliced it into the #1 sensor at the ECU. Anyway, it took me 15 mins and NO money to fix it. She drives as good as ever and no more CHECK ENGINE LITE. Im not telling anyone to do it, im just telling you what i did so you do what you will or won't. Don't Hate!

(when in fact #2 was now cut out of the picture because it had decided to lay down on the job) Moral of the story: don't lay down on the job or you'll be cut out of the picture and someone else will be fooled into doing your job and theirs too!
