PID: N/A
SPN: 3055
FMI: 2
Description: ICP/IPR adaptation in-range fault
Troubleshooting:
The Injection Control Pressure (ICP) system is controlled by the Electronic Control Module
(ECM) to regulate the amount of fuel pressure in the fuel injections.
Probable causes:
1) Oil level and quality
2) ICP system leak
3) IPR sensor or circuit fault
4) IPR valve sticking or stuck
5) Oil additive package worn out, foaming (overfilled)
6) High pressure oil pump worn out or leaking
7) High pressure oil leakage
8) Injector static leakage
9) Injector Oil Inlet Adapter (Puck) Assembly leakage
10) Engine brake control valve leakage

Description: DPFIT signal erratic, intermittent, or incorrect
Troubleshooting:
The Diesel Particulate Filter Inlet Temperature (DPFIT) sensor measures the temperature of
the inlet temperature of the Diesel Particulate Filter. The Diesel Particulate Filter Inlet
Temperature (DPFIT) works with the Diesel Oxidation Catalyst Inlet Temperature (DOCIT),
Diesel Oxidation Catalyst Outlet Temperature (DOCOT), and Diesel Particulate Filter
Differential Pressure (DPFDP) sensors to operate and control the regeneration cycles of the
Aftertreatment system.
Probable causes:
1) Biased DPFIT circuit or sensor

Description: DPFIT signal Out of Range HIGH
Troubleshooting:
The Diesel Particulate Filter Inlet Temperature (DPFIT) sensor measures the temperature of
the inlet temperature of the Diesel Particulate Filter. The Diesel Particulate Filter Inlet
Temperature (DPFIT) works with the Diesel Oxidation Catalyst Inlet Temperature (DOCIT),
Diesel Oxidation Catalyst Outlet Temperature (DOCOT), and Diesel Particulate Filter
Differential Pressure (DPFDP) sensors to operate and control the regeneration cycles of the
Aftertreatment system.
Probable causes:
1) DPFIT signal OPEN or short to PWR
2) SIG GND circuit OPEN
3) Failed DPFIT sensor

Description: DPFIT signal Out of Range LOW
Troubleshooting:
The Diesel Particulate Filter Inlet Temperature (DPFIT) sensor measures the temperature of
the inlet temperature of the Diesel Particulate Filter. The Diesel Particulate Filter Inlet
Temperature (DPFIT) works with the Diesel Oxidation Catalyst Inlet Temperature (DOCIT),
Diesel Oxidation Catalyst Outlet Temperature (DOCOT), and Diesel Particulate Filter
Differential Pressure (DPFDP) sensors to operate and control the regeneration cycles of the
Aftertreatment system.
Probable causes:
1) DPFIT signal circuit short to GND
2) Failed DPFIT sensor
