Fault code
J1939 SPN
J1939 FMI
Intake manifold 1 temperature - Data erratic,
436
intermittent, or incorrect. The intake manifold
105
temperature sensor is reading an erratic value
2
at initial key on or while the engine is running.
Battery 1 voltage - Data valid but below normal
441
operational range - Moderately severe level.
168
ECM supply voltage is below the minimum
18
system voltage level.
Battery 1 Voltage - Data valid but above normal
442
operational range - Moderately severe level.
168
ECM supply voltage is above the maximum
16
system voltage level.
Injector metering rail 1 pressure sensor circuit -
451
Voltage above normal, or shorted to high
157
source. High signal voltage detected at the rail
3
fuel pressure sensor circuit.
Injector metering rail 1 pressure sensor circuit -
452
Voltage below normal, or shorted to low source.
157
Low signal voltage detected at the rail fuel
4
pressure sensor circuit.
Injector metering rail 2 pressure sensor circuit -
483
Voltage above normal or shorted to high
1349
source. High signal voltage detected at the fuel
3
rail 2 pressure sensor circuit.
Injector metering rail 2 pressure sensor circuit -
484
Voltage below normal or shorted to low source.
1349
Low signal voltage detected at the fuel rail 2
4
pressure sensor circuit.
Sensor supply 6 circuit - Voltage above normal
515
or shorted to high source.
3514
High voltage detected on the +5 volt sensor
3
supply circuit to the fuel rail pressure sensor.
Sensor supply 6 circuit - Voltage below normal
516
or shorted to low source.
3514
Low voltage detected on the +5 volt sensor
4
supply circuit to the fuel rail pressure sensor.
Injector metering rail 1 pressure - Data valid but
553
above normal operational range - Moderately
157
severe level. The ECM has detected that fuel
16
pressure is higher than commanded pressure.
Crankcase pressure - Data valid but above
555
normal operational range - Moderately severe
101
level. The crankcase breather filter requires
16
maintenance.
Crankcase pressure - Data valid but above
556
normal operational range - Most severe level.
101
The crankcase breather filter requires
0
maintenance.
