Thanks for the suggestion. I ended up taking it to the dealer. They did a manual oil pressure check and it was normal at idle. So, it looks like there might a problem with either the guage itself or the wiring. The dealer offered to track it for me. They said it could take up to 4 hours to run the problem down. I think I'll live with it now that I know the pressure's actually ok.
