S06 INSTRUMENTATION
SPN SPN Name SPN Description
3516 Aftertreatment 1 Diesel Exhaust Fluid
Concentration
A measure of the concentration of urea in water.
3563 Engine Intake Manifold #1 Absolute
Pressure
The absolute pressure measurement of the air intake manifold.
3606 Engine Controlled Shutdown Request A signal issued by the engine control system to a user or external system
requesting for a controlled shutdown.
3607 Engine Emergency (Immediate)
Shutdown Indication
A signal issued by the engine control system to a user or external system
indicating that it is immediately shutting the engine down.
3673 Engine Throttle Valve 2 Position
The sensed position feedback of the valve, coming from a second electrical
actuator for a second throttle plate, used to regulate the supply of a fluid, usually
air or fuel//air mixture.
3822 Engine Exhaust Gas Recirculation 1
Valve 2 Position
The position of the second exhaust gas recirculation valve expressed as a
percentage of full travel.
3936 Aftertreatment Diesel Particulate
Filter System
Non-specific failures of the aftertreatment diesel particulate filter system.
4090 NOx limits exceeded, root cause
unknown
On-Board Diagnostics has determined that the limits for NOx in the exhaust
stream have been exceeded, but the root cause cannot be determined by the OBD
system.
4094
NOx limits exceeded due to
Insufficient Diesel Exhaust
Fluid Quality
On-Board Diagnostics has determined that the limits for NOx in the exhaust
stream have been exceeded due to an insufficient diesel exhaust fluid quality.
4095
NOx limits exceeded due to
Interrupted Diesel Exhaust
Fluid Dosing
On-Board Diagnostics has determined that the limits for NOx in the exhaust
stream have been exceeded due to an interruption in diesel exhaust fluid dosing
activity.
4096
NOx limits exceeded due to Empty
Diesel Exhaust Fluid
Tank
On-Board Diagnostics has determined that the limits for NOx in the exhaust
stream have been exceeded due to the diesel exhaust fluid tank being empty.
4201 Engine Speed 1 The engine speed as measured by speed sensor 1.
4202 Engine Speed 3 The engine speed as measured by speed sensor 3.
4225 NOx limits exceeded due to error in
the NOx control system
On-Board Diagnostics has determined that the limits for NOx in the exhaust
stream have been exceeded due to an error in the NOx control system.
4301 Aftertreatment 1 Fuel Injector 1
Heater Control
Heating level that the controller is commanding the aftertreatment 1 fuel injector 1
heater control to maintain.
4334 Aftertreatment 1 Diesel Exhaust Fluid
Doser Absolute Pressure
The SCR dosing diesel exhaust fluid absolute pressure (measured closest to
dosing valve) for aftertreatment system 1 (exhaust bank 1).
4337 Aftertreatment 1 Diesel Exhaust Fluid
Dosing Temperature
The diesel exhaust fluid dosing temperature (measured closest to dosing valve)
for aftertreatment system 1 (exhaust bank 1).
4341 Aftertreatment 1 Diesel Exhaust Fluid
Line Heater 1 Preliminary FMI
Used to identify the applicable J1939-73 FMI detected in the diesel exhaust fluid
line heater 1, by the manufacturer’s control software in exhaust bank 1.
4343 Aftertreatment 1 Diesel Exhaust Fluid
Line Heater 2 Preliminary FMI
Used to identify the applicable J1939-73 FMI detected in the diesel exhaust fluid
line heater 2, by the manufacturer’s control software in exhaust bank 1.
4345 Aftertreatment 1 Diesel Exhaust Fluid
Line Heater 3 Preliminary FMI
Used to identify the applicable J1939-73 FMI detected in the diesel exhaust fluid
line heater 3, by the manufacturer’s control software in exhaust bank 1.
4347 Aftertreatment 1 Diesel Exhaust Fluid
Line Heater 4 Preliminary FMI
Used to identify the applicable J1939-73 FMI detected in the diesel exhaust fluid
line heater 4, by the manufacturer’s control software in exhaust bank 1.
4374 Aftertreatment 1 Diesel Exhaust Fluid
Pump Motor Speed
Rotational speed of the motor driving a pump for diesel exhaust fluid used in an
aftertreatment system.
