Oil pressure gauge

the pressure gauge on my instrument panel "clicks" on and off. sometimes it takes a good warm-up until it pops up to normal range. My oil level is correct. I thought it was the cold weather, but it seems like a bad signal. do I start with the sending Unit??

I'd say so. Most OEM Ford oil pressure sending units don't actually measure the pressure, its actually just more like an ON/OFF switch which tells you whether or not it has oil pressure, not how much. They're pretty simple to replace, just unscrew it from the side of the block with a wrench and screw in another. Wiring is pretty simple and straight forward.

Other possible thoughts could be a bad ground for the gauge, or a bad connection but if its kicking in once its warm then it'd rule that out. LR

Replace the sending switch and you'll correct that issue. It's a common Ranger thing.

agreed, they are junk, if you really wanna know pressure just buy an aftermarket oil pressure gauge IMO
