Must be the sending unit???

[Canadian1968]

My Oil pressure gauge isn't working. The other gauges are working perfectly.

If I ground the sending wire the gauge will climb and max itself out. I get a pulsing voltage from the sending wire with my DVOM. So it sounds like the sending unit itself it toast??? OR am i missing something.

I dont have anything helpful to say, but I have the same problem.

Yes, looks like bad sending unit. Make sure you dont wrap the new one with teflon or it can cause issues.

You need a new sending unit.
