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

 

welcome to R-F, Andy!

 

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

 

welcome to RF. I have to replace my pressure switch too. Maybe today who knows. Its been doing that for about a year i just don't feel like replacing it but the check gauge light has taken its toll on me haha

 

general discussion

 

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