As with any repair, first you have to diagnose. Go from simplest to hardest, always! With that said, check/replace your oil pressure sensor first.

Cold engines/oil tend to cause higher pressures than normal operating temps. I would take the advise like mentioned above and first replace the oil pressure sending unit.
