Fault code
J1939 SPN
J1939 FMI
Aftertreatment diesel particulate filter missing -
1993
Condition exists. The aftertreatment diesel
4795
particulate filter in the exhaust system is not
31
present.
Sensor supply 4 circuit - Voltage above normal,
2185
or shor ted to high source. High voltage
3512
detected at 5 VDC sensor supply circuit to the
3
accelerator pedal position sensor.
Sensor supply 4 circuit - Voltage below normal,
2186
or shorted to low source. Low voltage detected
3512
at 5 VDC sensor supply circuit to the
4
accelerator pedal position sensor.
VGT Actuator driver circuit - Root cause not
known.
2198
Intermittent communication between the smart
641
VGT controller and the ECM has been
11
detected. The VGT controller is not interpreting
the J1939 message from the ECM correctly.
EGR Valve position circuit - Voltage below
2272
normal or shorted to low source. Low signal
27
voltage has been detected at the EGR valve
4
position sensor circuit
Exhaust gas recirculation valve delta pressure
2273 sensor circuit - Voltage above normal or
411 shorted to high source. High signal voltage
3 detected at the EGR differential pressure
sensor circuit.
Exhaust gas recirculation valve delta pressure
2274
sensor circuit - Voltage below normal or shorted
411
to low source. Low signal voltage detected at
4
the EGR differential pressure sensor circuit.
Turbocharger 1 speed - Data valid but above
2288
normal operating range - Least severe level.
103
High turbocharger speed has been detected by
15
the ECM.
Electronic fuel injection control valve circuit -
2311
Condition exists. Fuel pump actuator circuit
633
resistance too high or too low, or an intermittent
31
connection has been detected.
Engine camshaft speed / position sensor - Data
2322
erratic, intermittent, or incorrect.
723
Camshaft engine speed sensor intermittent
2
synchronization.
2349 EGR Valve control circuit - Current below
2791 normal or open circuit. Motor terminal or motor
5 coil open circuit has been detected by the ECM.
