Oil Pressure gauge show low oil pressure and Oil and Coolant light comes on when engine is cold. After 3-4 minutes and engine reaches normal temperature the oil pressure comes up to normal and the lights go off.

Using mfg. Recomended 5W-20W oil. Could this be a sensor or somthing more serious?

Sounds like the oil pressure relief valve is sticking check the oil pressure with a mechanical gauge if normal replace the oil pressure switch abnormal could be oil pump or engine bearings
