E0161-01-Engine Oil Pressure Valid Below Normal (B.60.A.95.91 - G.30.C.20) - New Holland CX720 Repair Manual

E0161-01-Engine Oil Pressure Valid Below Normal (B.60.A.95.91 -
G.30.C.20)
E0161-01 - Engine Oil Pressure Valid Below Normal
Cause:
Engine running for > 10 seconds with pressure < 1.0 bar .
Possible failure modes:
1. The engine oil pressure sensor B-30 (NH 7.5L) or B-52 (IVECO) reports that the oil pressure is below acceptable
limits - this is normal operation of the circuit and indicates an oil pressure failure.
2. Oil pressure sensor B-30 (NH 7.5L) or B-52 (IVECO) failure.
Solution:
1. The presence of this fault code indicates the engine oil pressure has dropped below 1.0 bar while the engine
has been running for over 10 seconds . This is not a failure to be diagnosed electrically unless the sensor is
faulty.
A. Locate and repair the mechanical fault in the oil pressure system.
B. If no oil pressure system fault can be found, replace the oil pressure sensor B-30 (NH 7.5L) or B-52
(IVECO). Continue troubleshooting with Step 2.
2. Visually inspect the harness and connectors for damage, bent or dislocated pins, broken or pinched wires.
A. Repair any damage found during visual inspection.
B. If no damage is found, erase the fault code and continue operation.
