Function
Indicates a specific cylinder in the firing order.
Senses crankshaft position and engine speed for functions such
as fuel control strategy.
Sensor measures pressure between the Diesel Oxidation Catalyst
(DOC) and the Diesel Particulate Filter (DPF) in the aftertreatment
assembly located in the exhaust system of the vehicle.
Sensor measures pressure on the outlet of the after-treatment
device in the exhaust system of the vehicle. Located after the DPF
that is within the aftertreatment device.
Temperature measured at the outlet of the after-treatment system
that is installed within the exhaust system of the vehicle. It's
located after the DPF that is within the aftertreatment unit.
DOC Temperature In - Temperature measured at the inlet of
the after-treatment device in the exhaust system of the vehicle.
Located before the DOC that is within the after-treatment device.
Temperature measured between the DOC and the DPF in the
aftertreatment assembly located in the exhaust system of the
vehicle.
Senses EGR pressure for EGR control.
Senses EGR exhaust temperature after EGR cooler. Used for
EGR system diagnosis.
Senses coolant temperature for functions such as engine
protection, fan control and engine fueling.
Senses gallery oil pressure for functions such as engine protection.
Senses oil temperature for functions such as reducing variation
in fuel injection and fan control.
Senses fuel line pressure
Compensates fuel line pressure
Senses turbo boost for functions such as smoke control and engine
protection.
Senses boost temperature
Senses fuel temperature for functions such as engine fueling.
Senses turbo out air temperature.
Monitors turbo speed.
Detects water in the fuel filter that alerts the owner/driver that the
fuel filter needs to be dried out.
