01 malibu low oil pressure light comes on & off

[copdills]

I have a 2001 malibu the low oil pressure light comes on at times for about 5 mins when I first start the car ,then goes off , but it seems to flash off and on until the 3100 engine has fully warmed up , any ideas i was thinking it might be the pressure sensor, it has 95,000 miles on it and the oil is changed regular and was changed four days before this problem started,engine still sounds normal

Thanks copdills

Get a mechanical pressure gage on it and confirm that the oil pressure is in fact ok first.
