It sounds like the oil pressure sender. I wouldn't expect a bad oil pump to give good normal pressures like you have. The ones I have seen are low all around and ultra low at hot idle. The only way to truly tell though is to put a mechanical oil pressure gauge on it. Changing out an oil pressure sensor is pretty easy though and cheaper than buying another oil pressure gauge setup
