Of course, verify that your oil level is still good, not to full, not too low.

Double check that the correct sender is installed near the water pump.  It's 0.9 bar I think, I had a 1.8 bar on mine when I first got it and got a lot of false alarms from that.

If you can, you need to check the pressure with a gauge so you know what you really have.  Harbor Freight sells an inexpensive oil pressure tester.  Or have a shop do it.  Without knowing what your actual hot oil pressure is, everything else is just guesswork.
