Why are Motorcraft oil pressure switches such poor quality? Every one of the Explorer's, Mountaineer's, my Sport Trac (SOHC's and V8's) and my daughter's 3.0L V6 Ford Fusion has had intermittent, or occasional, "CHECK GAGE" light come on because the oil pressure switches register no/low oil pressure. I just bought 3 brand new Motorcraft oil pressure switches from RA. I installed one on my freshly rebuilt Sport Trac's SOHC. one on my daughter's Fusion and I was going to install the remaining one in our 2000 Mountaineer (which banged the oil pressure needle so hard and so frequently that to broke the oil gauge's needle stop peg off the instrument cluster's face).
Putting a real oil pressure gauge on these vehicles indicated no issues with low oil pressure. I replaced the pressure switch while my Sport Trac's engine was out, because it's a bit of a PITA to change it with the engine in the truck. I figured I was being proactive, as I recalled it once failed to register oil pressure after sitting for a couple of months. The new switch worked fine for about 100 miles and then would not work intermittently. As I had a second new switch handy I installed it. Problem solved (for a while anyway).
The next time I have a Motorcraft oil pressure switch crap-out on me I'm going to just buy whatever aftermarket band that Autozone sells. As oil pressure is so critical on the SOHC engines, I had also installed a new OE oil pump while the engine was apart. I plan to also install a permanent "real" oil pressure gauge on my SOHC using a oil sandwich-style oil filter adapter, which I can also use to install my pre-oiler as it comes with 2 ports.
