Cummins ISB CM850 (2003-06) Fault Code: 143 (Auto) PID: 100 SPN: 100 FMI: 1 Engine Oil Rifle Pressure – Data Valid but Below Normal Operational Range – Moderately Severe Level. Engine oil pressure signal indicates engine oil pressure is below the engine protection warning limit.
The engine oil pressure sensor is located on the left side of the engine block.
Possible repairs:
1)Refer to the Lubricating Oil Pressure Below or Above Normal troubleshooting tree in Troubleshooting and Repair Manual, ISC, QSC8.3, ISL and QSL9 Engines, Bulletin 4021418 or ISBe and ISB (Common Rail Fuel System) Series Engines, Bulletin 4021271.
