Make: International
Engine: MaxxForce DT (2010 & Newer)
PID: N/A
SPN: 164
FMI: 18
Description: ICP below desired level
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) Trapped air in ICP system (after system was opened)
3) Aerated or contaminated engine oil
4) IPR circuit fault or failed (sticking) valve
5) High-pressure oil pump failure

Description: ICP below desired level
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) High-pressure oil pump
2) Puck seal leakage
3) Injector
4) Injector static leakage
5) ICP sensor O-ring leakage
6) Engine Compression Brake (ECB) sensor O-ring leakage
7) ECB relief valve stuck
8) IPR valve sticking
9) Oil rail end cap seal leakage

Description: AIT signal erratic, intermittent, or incorrect
Troubleshooting:
Module (ECM) to calculate the correct amount of Exhaust Gas Recirculation during engine
operation.
Probable causes:
1) Biased Air Inlet Temperature (AIT) signal or circuit
Make: International
Engine: MaxxForce DT (2010 & Newer)
PID: N/A
SPN: 172
FMI: 3
Description: AIT signal Out of Range HIGH
Troubleshooting:
Module (ECM) to calculate the correct amount of Exhaust Gas Recirculation during engine
operation.
Probable causes:
1) AIT signal circuit OPEN or short to PWR
2) SIG GND circuit OPEN
3) Failed AIT sensor
