Hey everyone,
I've got a coworker's Expedition, not sure the year, its 97-99, 5.4L 2WD. We're wanting to change the oil pressure sending unit, but shamefully, I can't find it! I've never looked for one on any Ford vehicle despite owning an F-150 myself. I've changed the same part on other makes of vehicles so its not like I don't recognize them or know what they are. I just can't find it on this vehicle. Does anyone have any tips or hints for me? Or better yet, pictures? I want to help the guy out if I can, but I'm stumped. I looked on my truck to get an idea of the layout underneath but I can't find it on mine either so I'm sure I'm just missing the forest for the trees so to speak. Any help would be appreciated, thank you!

The oil pressure sending unit is located behind the oil filter. I found it to be easiest if you take the left front wheel and shock off, and as I recall, the plastic splash guard can be removed too to improve access. Don't forget to practice bending your elbow backwards. It's hard to get to so make sure you have plenty of time and patience before you start. I ended up cutting a box end wrench in half so I could turn it more than a 32nd of a turn each time.
Good luck!
