sensor or connector. 0 = short 80 = open
First thing I'd do is pull the connector, clean it
and reinstall.

If it's like the 93 4.0 yours is down on by the oil filter.

There is no real torque given for installation since you
can't get a torque wrench on it anyway. :) I just run it
down by hand then turn it in with a wrench till it feels
snug. If it leaks you just turn it in a bit more then
check later. A dab of sealant around the last few
threads helps.

Re: Oil pressure sensor?
 

Ok here's a question. I went and found the sensor and tried to unplug it to
clean it but it is a new kind of connection I have never seen before. Seems
all the connections (most) have these new (black with a red thing on them)
Does it slide (red thing) to lock them? what is the correct way to
disconnect / connect without breaking them?, (which I am famous for)
