Fault code
J1939 SPN
J1939 FMI
Aftertreatment intake NOx sensor circuit -
1885
Voltage below normal or shorted to low source.
3216
An internal circuit error has been detected by
4
the aftertreatment intake NOx sensor.
Aftertreatment outlet NOx sensor circuit -
1887
Voltage below normal or shorted to low source.
3226
An internal circuit error has been detected by
4
the aftertreatment outlet NOx sensor.
1896 EGR valve controller - Out of calibration.
2791 The EGR valve has failed the automatic
13 calibration procedure at initial key ON.
Aftertreatment diesel particulate filter differential
1921 pressure - Data valid but above normal
3251 operating range - Moderately severe level. The
0 soot load of the aftertreatment diesel particulate
filter has exceeded the recommended limits.
Aftertreatment diesel particulate filter differential
pressure - Data valid but above normal
1922 operating range - Most severe level.
3251 The soot load of the aftertreatment diesel
0 p a r t i c u l a t e f i l t e r h a s e x c e e d e d t h e
recommended limits. Engine protection derate
is enabled.
Ecu power output supply voltage 1 - Data valid
1938
but below nor mal operational range -
3597
Moderately severe level. Low battery voltage
1
detected by the VGT actuator.
Crankcase pressure - Data erratic, intermittent,
1942 or incorrect. The ECM has detected that the
101 crankcase pressure signal is reading an erratic
2 value at initial key ON or during engine
operation.
EGR valve control circuit calculated over
1961 temperature - Data valid but above normal
2791 operational range - Least severe level.
0 High EGR valve driver temperature has been
detected.
VGT Actuator driver over temperature
1962 (calculated) - Data valid but above normal
641 operating range - Least severe level.
0 High internal VGT actuator temperature has
been detected.
Crankcase pressure - Data valid but above
1974
normal operating range - Moderately severe
101
level. The crankcase breather filter requires
16
maintenance.
