8
Accelerator pedal or lever position sensor 2
circuit frequency - Abnormal frequency or pulse
width or period. The accelerator pedal position
sensor reading is out of range.
The engine will operate in Limp Home mode.

9
After treatment diesel par ticulate filter
temperature sensor module - Abnormal update
rate. No communications on the J1939 data link
between the ECM and the aftertreatment diesel
particulate filter temperature sensor module.
Possible reduced engine performance.
4152
5743
9
Aftertreatment selective catalytic reduction
temperature sensor module - Abnormal update
rate. No communications on the J1939 data link
between the ECM and the aftertreatment SCR
temperature sensor module.
Possible reduced engine performance.
4155
5746
3
Aftertreatment 1 diesel exhaust fluid dosing unit
heater relay - Voltage above normal, or shorted
to high source. High signal voltage detected at
the aftertreatment diesel exhaust fluid dosing
unit heater relay circuit.
Possible reduced engine performance.
4156
5746
4
Aftertreatment 1 diesel exhaust fluid dosing unit
heater relay - Voltage below normal, or shorted
to low source. Low signal voltage detected at
the aftertreatment diesel exhaust fluid dosing
unit heater relay circuit.
Possible reduced engine performance.
4157
4376
7
Aftertreatment diesel exhaust fluid return valve -
Mechanical system not responding or out of
adjustment. A stuck aftertreatment diesel
exhaust fluid return valve has been detected.
None on performance.
4158
5742
12
After treatment diesel par ticulate filter
temperature sensor module - Bad intelligent
device or component. An internal error has
been detected in the aftertreatment diesel
particulate filter temperature sensor module.
Possible reduced engine performance.

3
After treatment diesel par ticulate filter
temperature sensor module - Voltage above
normal, or shorted to high source.
High battery supply voltage detected at the
after treatment diesel par ticulate filter
temperature sensor module.
Possible reduced engine performance.
4162
5742
4
After treatment diesel par ticulate filter
temperature sensor module - Voltage below
normal, or shorted to low source.
Low battery supply voltage detected at the
after treatment diesel par ticulate filter
temperature sensor module.
Possible reduced engine performance.
