DIAGNOSTIC MANUAL
Exhaust Back Pressure Valve
(EBPV)
A valve that regulates the amount of air pressure applied to the EBPV pneumatic actuator.
Exhaust brake
A brake device using engine exhaust back pressure as a retarding medium.
Exhaust Gas Recirculation
(EGR)
A system used to recirculate a portion of the exhaust gases into the power cylinder in order to reduce
oxides of nitrogen.
Exhaust Gas Temperature
(EGT)
The temperature of exhaust gases.
Exhaust Gas Recirculation
Temperature (EGRT) sensor
A thermistor sensor that detects the exhaust gas temperature entering the EGR cooler.
Exhaust Gas Recirculation
(EGR) valve
The EGRV controls the flow of exhaust gases to the intake manifold. The EGRV is integrated with an
EGR Position (EGRP) sensor.
Exhaust manifold
Exhaust gases flow through the exhaust manifold to the turbocharger exhaust inlet and are directed to
the EGR cooler.
Exhaust Manifold Pressure
(EMP) sensor
A variable capacitance sensor used to indicate air pressure in the exhaust manifold.
Exhaust Manifold Temperature
(EMT) sensor
A thermistor sensor used to indicate air temperature in the exhaust manifold.
Failure Mode Indicator (FMI)
Identifies the fault or condition effecting the individual component.
Fuel Delivery Pressure (FDP)
sensor
A variable capacitance sensor that monitors fuel pressure coming from the fuel tank and sends a signal
to the ECM.
Fuel pressure
The force fuel exerts on the fuel system as it is pumped through the fuel system.
Fuel Pressure Control Valve
(FPCV)
The FPCV controls the fuel pressure to the fuel rails and is controlled by the ECM. FPCV control depends
on fuel pressure and fuel temperature.
