2007 Chevrolet Impala • 120,000 miles

Low oil presure light still comes on even after replacement of oil presure sensor. What else or what to do

I would think the next thing to do is to put a pressure gauge on the oil gallery and see what the actual oil pressure is. If the bearing clearance is too great in the motor, the oil pressure will be low. Heavier viscosity oil might be a short term fix as well.
