You can easily pop that pump off to inspect the gear. If it's chronically low, it's likely a failed regulator. If it doesn't match what the ECM reads, it's likely a failed sensor.Cummins ISX 485ST low oil pressure Discussion in 'Kenworth Forum' started by Nefi, Jan 16, 2016. Page 2 of 3 < Prev 1 2 3 ...
