Yesterday morning when I left for work I noticed that my oil light was faintly on... I checked the oil and it seemed fine. ( I am concerned because I got in an accident about 2 weeks ago and i dont know if it could be from that although the only things that got replaced were the front bumper, hood, headlights and radiator support) Started driving and it went off. Is this an indication that I need a sensor or that my oil pump is going or something? Is there a way to test it or just wait until it goes?
