Thread: Oil pressure light came on help....

I was doing some scans this afternoon and my oil pressure light came on.
But it only apears when i'm at idle.
Checked the oil and it checks out good, no leaks.
Its the red ligh on the left of the cluster.
About a month a go i replaced the oil pressure sensor cause it was leaking oil.
Could it be the sensor again?
Or could it be the oil pump?
How do you check the oil pump?
