On a car that i work on, 2001 convertible w/2.0t ecopower, i have been battling an oil pressure light. The oil level is fine, we changed the oil to rule it out. also i have replaced the oil pressure sensor. The valve cover was pulled to see if there was any sign sludge, it was clean. The light comes on after the car is warmed up and happens at low rpm, right after it shifts,(auto). Also the car runs drive and sounds normal. Any thing else to look at or check before i have to pull the pan and check the screen.
