Pontiac Repair: 1997 pontiac sunfire, oil pressure sender, low oil pressure

Question
My oil light has been on and i just got a oil change yesterday and the oil light is still on. It comes on when the car is going under MPH but off when accelerating. i was thinking that it was the oil pump or the sending unit, but i was wondering if theres a reset on it.

Answer
Hi
FIRST I will tell you to take it to a repair shop and have the Oil pressure measured with a manual gage attached to engine to determine EXACT pressure.
From there they should be able to determine if it is the Oil pressure sender unit, oil pump or bearing failure (either main, rod or cam bearings can cause low oil pressure).
I hope this helps.
Good Luck
