Oil light on

I have the check oil light coming on when my van is idling at a stop light or while in park. I just changed my oil and filter, about 1 year ago U had the same problem and changed the sending unit and it help for about a year. I am thinking about getting a regular pressure gauge and hooking it up to see what the oil pressure is really doing. Any other ideas would be great.

Thank you

Oil Light comes on to 'flicker' at low rmp on hot engine 'in gear' at stop.
Putting vehicle in Neutral or Park at stop and light goes out.
Will a new Oil Pressure Sensor fix this problem?
And where is same located on engine?

I have just bought a 2001 Dodge caravan. I noticed that the oil light comes on at idle and goes agin when I pull away. I guess the first step is to change the sensor and ensure the correct weight of oil is in.

Assuming this was done what would be the next step, could the oil pump be faulty although it works with revs?

Thanks

I just had the oil and filter chaqnged, but the light still comes on when the car is first started (after the self-test, of course). Is there a way to reset the interval counter or is it actually a case of low oil pressure?
