Cummins ISX CM870 (2003-06) Fault Code: 482 PID: P094 SPN: 94 FMI: 1/18 Fuel Pressure Low – Data Valid But Below Normal Operating Range – Moderately Severe Level.
The fuel pressure is monitored by the ECM. If the rail fuel pressure is lower than an acceptable level for a given set of engine operating conditions, the fault code is logged.
Possible causes:
1)A damaged or sticking drain-back valve located in the fuel supply circuit in the integrated fuel system module (IFSM). The IFSM is located directly above the fuel lift pump.
Possible repairs:
1)Fill the fuel tanks.
2)Prime the fuel system.
3)Repair or replace the fuel lift pump.
4)Repair or replace the fuel shutoff valve.
5)Replace the 1724 kPa [250 psi] regulator.
6)Replace the suction-side fuel filter or repair the cause of high inlet restriction.
7)Repair or replace the fuel shutoff valve.
8)Replace the pressure fuel filter.
9)Replace the rail fuel pressure sensor.
