I've searched and I've found several numbers regarding this issue. I need to know what the resistance numbers are for an oil pressure sending unit. I've read from one person that it's 240 to 33 ohms, others say that it's 0 to 90 ohms. I've tried looking for a page outside of the forums to gather this information. Any help will be greatly appreciated.

I have to troubleshoot the pegged gauge and I have to eliminate the sending unit. Thanks again.

 

Only info I have is for the sender off my '96 S truck. Don't know if GM has changed it since then, but here's the curve I made from that sender for my GN swap:

 

Right on, brotha! Thanks a whole heap, man.
