Question, I've seen the term "upstream" and the term "downstream" used for 02 sensors. When I went on to Amazon.com To find the O2 sensor for my 2005 Jaguar S type (3.0 engine) it just showed one type which said "Downstream." In your description, you say "upstream." So, are there TWO 02 sensors? (One upstream and one downstream?) Do I now need to go find one that's upstream? Thanks 🙂
Thanks for the tutorial, and I have two questions to make sure I do the same job properly. Which size wrench/socket did you use? Which specific parts did you have to remove to get to the sensor?
