Make: International
Engine: MaxxForce DT (2010 & Newer)
PID: N/A
SPN: 3464
FMI: 11

Description: ETC short to GND
Troubleshooting:
The Engine Throttle Valve (ETV) regulates how much air enters the engine. The valve opens
and closes to allow for more or less air intake as engine conditions require.
Probable causes:
1) Jammed sector gear
2) Stalled motor
3) Damaged butterfly valve
4) Ice water intrusion into electrical section in intake throttle

Description: Intake Throttle Actuator Control Short circuit
Troubleshooting:
The Engine Throttle Valve (ETV) regulates how much air enters the engine. The valve opens
and closes to allow for more or less air intake as engine conditions require.
Probable Causes:
1) Short Circuit

FMI: 1

Description: AFT Fuel Pressure 1 below desired (Low system pressure)
Troubleshooting:
The Aftertreatment Fuel Doser (AFTFD) is supplied with pressurized fuel from the fuel filter
housing. When a regeneration is required, The Doser Control Unit (DCU) sends voltage to the
AFTFD to inject fuel into the turbo exhaust pipe.
Probable causes:
1) Low fuel delivery pressure
2) Restricted fuel filter
3) Aftertreatment (AFT) fuel shutoff valve failure
4) Biased AFT fuel pressure 1 sensor or circuit
