What I'm trying to find out is how to determine whether my oil pressure sender is working. It's somewhat involved to remove that thing and I don't want to do it if I don't need to. I've read about testing the sender's resistance while the engine is running but wanted to get Walt's opinion.

Sorry, I misunderstood. Does the pointer move off the stop up to 0, or does it stay all the way down? I drove my car to the airport this morning, but I can't remember if the 0 is a little above the pointer resting point or not. However, we know now the resistor values:
0 bar - 9.5 ohms
5 bars - 168.9 ohms
Get a 165 ohm resistor and place it between the wire of the sender unit and ground and see if your gauge moves up close to the 5 bar mark. Just for cross checking I would also get a 80 ohm resistor to check if the gauge indicates in-between.
