At this time, the only thing I can suggest is whatever O2 sensor you purchase, test it before you install it. The bosch 12009 re-labels I received from that random seller on amazon were not correct. They were wired incorrectly, the wrong resistance, and did not respond correctly with heat. I have been scooping up new old stock o2 sensors when I find them on ebay but I have not seen one since september. I gave my last one to my brother for his XJ. You may have an easier time in a junk yard. It's sad.
