Make: International
Engine: MaxxForce DT (2010 & Newer)
PID: N/A
SPN: 172
FMI: 4
Description: AIT signal Out of Range LOW
Troubleshooting:
Module (ECM) to calculate the correct amount of Exhaust Gas Recirculation during engine
operation.
Probable causes:
1) AIT signal circuit short to GND
2) Failed AIT senso
Make: International
Engine: MaxxForce DT (2010 & Newer)
PID: N/A
SPN: 173
FMI: 2
Description: EGT signal erratic, intermittent, or incorrect
Troubleshooting:
The Exhaust Gas Temperature (EGT) sensor indicates exhaust gas temperature.
Probable cause:
1) Biased EGT sensor or circuit
2) Improper combustion of fuel in exhaust manifold
3) Over-fueling
4) External fuel source
