Make: International
Engine: MaxxForce DT (2010 & Newer)
PID: N/A
SPN: 164
FMI: 2

Description: ICP signal erratic, intermittent, or incorrect
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) Connections
2) Failed/biased sensor
3) Injector
4) Circuit
5) Sticking IPR valve

Make: International
Engine: MaxxForce DT (2010 & Newer)
PID: N/A
SPN: 164
FMI: 3

Description: ICP signal Out of Range HIGH
Troubleshooting:
The Injection Control Pressure (ICP) sensor indicates injection control pressure. ICP is
monitored to modulate the IPR.
Probable causes:
1) ICP signal circuit OPEN or short to PWR
2) SIG GND circuit OPEN
3) Failed ICP sensor

Make: International
Engine: MaxxForce DT (2010 & Newer)
PID: N/A
SPN: 164
FMI: 4

Description: ICP signal Out of Range LOW
Troubleshooting:
The Injection Control Pressure (ICP) sensor indicates injection control pressure. ICP is
monitored to modulate the IPR.
Probable causes:
1) ICP signal circuit short to GND
2) VREF-6 circuit OPEN
3) Failed ICP sensor

Make: International
Engine: MaxxForce DT (2010 & Newer)
PID: N/A
SPN: 164
FMI: 10

Description: ICP signal abnormal rate of change
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) Biased ICP sensor or circuit
2) ICP sensor or circuit fault
3) ICP valve or circuit fault
