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
.
