Oxygen sensor bank one upstream


Asked by Nov 15, 2013 at 10:41 PM about the 2006 Ford Expedition Eddie Bauer 4WD

Question type: General

How do you get to the disconnect on the
upstream oxygen sensor on a 2006 ford
expediton. I can get to the sensor with a 7-8
wrench just fine. But can't get to the
disconnect. It's up to far.  Anybody with
good sound advice.  Thanks in advance.

go ahead....use a vice grips...this part ain't gonna win any beauty contests for flatness of hexes~....just don't break that wire~


The disconnect unsnaps then to put it back you have to reconnect it by snapping it back together. I m not able to get fingers in close enough to do anything.


Oh yeah this is the one that they made those long curved pair of needle nose pliers for, you local parts store might have a pair for rent, they about 18 inchedstotal length and the end is curved.
