Hi,
I had purchased 4 sensors to replace all 4. However my mechanic
Told me that the car has 2 oxygen sensors only. So the two sensors which are each on either side of the engine visible from top view were changed.
I kept insisting that there are 2 more sensors to be changed
but couldn't indicate the location myself as neither my mechanic nor me knows the location.
So the 2 remaining oxygen sensors are still with me. We just don't know where the downstream sensors are located as we looked and looked but couldn't find the location of the downstream sensors.
I have seen a diagram view online that pertains to show
2 downstream sensors but my car doesn't seem to show them.
