SPN SPN Name SPN Description
3216 Aftertreatment 1 Intake NOx
The amount of combined NO and NO2 in the exhaust entering the aftertreatment
system measured by a NOx sensor at the aftertreatment intake, represented in
NOx molecule parts per million non-NOx molecules in exhaust bank 1.
3226 Aftertreatment 1 Outlet NOx
The amount of combined NO and NO2 in the exhaust entering the aftertreatment
system measured by a NOx sensor at the aftertreatment outlet, represented in
NOx molecule parts per million non-NOx molecules in exhaust bank 1.
3241 Aftertreatment 1 Exhaust Gas
Temperature 1
The reading from the exhaust gas temperature sensor located farthest upstream
in the aftertreatment system in exhaust bank 1.
3242 Aftertreatment 1 Diesel Particulate
Filter Intake Gas Temperature
Temperature of engine combustion by-products entering the diesel particulate
filter in exhaust bank 1.
3245 Aftertreatment 1 Exhaust Gas
Temperature 3
The reading from the exhaust gas temperature sensor located farthest
downstream in the aftertreatment system in exhaust bank 1.
3246 Aftertreatment 1 Diesel Particulate
Filter Outlet Gas Temperature
Temperature of engine combustion by-products leaving the diesel particulate filter
exhaust in exhaust bank 1.
3249 Aftertreatment 1 Exhaust Gas
Temperature 2
The reading from the exhaust gas temperature sensor located midstream of the
other two temperature sensors in the aftertreatment system in exhaust bank 1.
3251 Aftertreatment 1 Diesel Particulate
Filter Differential Pressure
Exhaust differential pressure measured between the intake and exhaust of a diesel
particulate filter in exhaust bank 1.

other two temperature sensors in the aftertreatment system in exhaust bank 2.
3340 Engine Charge Air Cooler 1 Intake
Pressure
Pressure of air at intake to 1st or only charge air cooler, from multiple first stage
turbochargers being cooled and feeding multiple second stage turbochargers.
3360 Aftertreatment 1 Diesel Exhaust Fluid
Controller
The Diesel Exhaust Fluid Controller has the ability to read attributes of the SCR
system, including but not limited to, diesel exhaust fluid level, diesel exhaust fluid
temperature, diesel exhaust fluid quality, and diesel exhaust fluid dosing rate.
3361 Aftertreatment 1 Diesel Exhaust Fluid
Dosing Unit
The diesel exhaust fluid dosing unit is a device that mixes the diesel exhaust fluid
and air, and delivers a metered quantity of this mixture to the exhaust stream.
3362 Aftertreatment 1 Diesel Exhaust Fluid
Dosing Unit Input Lines
The diesel exhaust fluid dosing unit is a device that mixes the diesel exhaust fluid
and air, such that it contains an input line from the air tank and an input line from
the diesel exhaust fluid tank.
3363 Aftertreatment 1 Diesel Exhaust Fluid
Tank Heater
Percentage of heating applied to the aftertreatment 1 diesel exhaust fluid tank
heater.
