oil pressure sending unit
Hello
2001 ranger 2.3 liter 5 speed 167k miles.
I see the oil gauge needle occasionally flicker an 1/8 inch or so. I heard this is a dummy gauge and it either has pressure or it does not. I was going to swap out unit.
I found it next to the oil filter under truck.
Any suggestions /tips in swapping this sending unit out?
Thanks

Dummy Gauge
Eric,
Yes, I believe you are correct: gauge is meant to show if there is pressure or if there isn't. I saw a link at the Ranger Station to a guy who builds 2.3L engines and has a trick to convert the dummy gauge into a functional gauge by soldering in a resistor or something. It's been a while, so I don't recall the details now.
Flicker could mean a bad gauge, bad connection, or it dies out for a second because the pressure drops. You may need to do some more trouble shooting to diagnose the issue properly.
Good luck!
Kevin

These trucks have crappy oil sending unit. Replace it and your flicker will go away.
But as a safety precaution, you should check your oil pressure just to make sure.
I installed a 3 pod A-pillar unit and added a rpm, oil pressure and volt meter gauge. Love it.
