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
Temperature measured at the outlet of the
after-treatment system that is installed within
the exhaust system of the vehicle.
• DOC
Inlet Temperature
Temperature measured at the outlet of the
after-treatment.
• DOC
Outlet Temperature
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
Sensor): Senses gallery oil pressure for
functions such as engine protection.
• Engine Oil Temperature Sensor (EOT
Sensor):
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
Sensor:
uses this information to compute the amount
of air entering the engine.
• Supply Fuel Temperature Sensor (SFT
Sensor):
Sensor:
functions such as engine fueling.
• Turbo
Sensor: Senses turbo out air temperature.
Sensor:
• 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.
