2.4  DDEC VI SENSORS 

•  Camshaft Position Sensor  (CMP Sensor): 

Indicates a specific cylinder in the firing 
order. 

•  Crankshaft Position Sensor (CKP Sensor): 

Senses crankshaft position and engine 
speed for functions such as fuel control 
strategy. 

•  DPF Inlet Pressure Sensor Measures 

pressure between the Diesel Oxidation 
Catalyst (DOC) and the Diesel Particulate 
Filter (DPF) in the aftertreatment assembly. 

•  DPF Outlet Pressure Sensor: Measures 

pressure on the outlet of the aftertreatment 
device in the exhaust system of the vehicle. 

•  DPF Outlet Temperature Sensor: 

Temperature measured at the outlet of the 
after-treatment system that is installed within 
the exhaust system of the vehicle.  

•  DOC Inlet Temperature Sensor: 

Temperature measured at the outlet of the 
after-treatment. 

•  DOC Outlet Temperature Sensor: 

Temperature measured between the DOC 
and the DPF in the aftertreatment assembly. 

•  EGR Delta Pressure Sensor: Senses EGR 

pressure for EGR control. 

•  EGR Temperature Sensor: Senses EGR 

exhaust temperature after EGR cooler. Used 
for EGR system diagnosis. 

•  Engine Coolant Temperature Sensor (ECT 

Sensor): Senses coolant temperature for 
functions such as engine protection, fan 
control and engine fueling. 

•  Engine Oil Pressure Sensor (EOP 

Sensor): Senses gallery oil pressure for 
functions such as engine protection. 

•  Engine Oil Temperature Sensor (EOT 

Sensor): Senses oil temperature for 
functions such as reducing variation in fuel 
injection and fan control. 

•  Fuel Line Pressure Sensor: Senses fuel 

line pressure. 

•  Fuel Compensation Pressure Sensor: 

Compensates fuel line pressure. 

•  Intake Manifold Pressure Sensor (IMP 

Sensor): Senses turbo boost for functions 
such as smoke control and engine protection. 

•  Intake Manifold Air Temperature Sensor 

(IMT Sensor): Senses pressure. The MCM 
uses this information to compute the amount 
of air entering the engine. 

•  Supply Fuel Temperature Sensor (SFT 

Sensor): Senses fuel temperature for 
functions such as engine fueling. 

•  Turbo Compressor Temperature Out 

Sensor: Senses turbo out air temperature. 

•  Turbo Speed Sensor (TSS): Monitors turbo 

speed for overspeed conditions. 

•  VGT Position Sensor/EGR Valve Position 

Sensor. 

•  Intake Air Throttle Valve Sensor. 
•  Exhaust Valve Recirculation Valve (EGR) 

Sensor.
