Dears,
I am currently diagnosing a Chevy Epic 2007. Sometimes, when Idling, the oil can light flashing on and off. This happen only when at idle and it rarely does this not every time.
I used many scanner like Gscan 1, Gscan2, Vpecker and Snape on Verus. The car doesnt have info regarding oil like temp, pressure and so on.
The owner has changed both oil pump and oil pressure which didn't recommend doing so. The problem still exists
I diagnosed the oil pressure sensor using dvom both wires (voltage) and the sensor are good.
I would start with a oil pressure test in place of the oil pressure sensor (1 can be had fairly cheap from harbor freight with adapters) to know what your pressure is at idle vs spec (low oil pressure is usually not caused by pump but rather by worn bearings allowing too much oil to flow by them)
