I recently changed the oil in my 2012 rubicon unlimited and after changing the oil, my oil pressure light came on. I have since replaced the cracked oil filter housing cap and the pressure sensor. Now I have the oil light and it is going into limp mode randomly. I have oil flow at the filter. I pulled the housing cap and had a buddy hold the throttle wide open and turn it over and was getting plenty of oil flow. The light only comes on under 900 rpm and goes off under load. I'm really hoping one of yall have a solution for these issues cause I am completely stumped.
