FAULT CODE LISTING
Fault Associated Hardware Reason Effect
(only with active code)
F284 ESS crankshaft position
sensor low.
Low voltage at pin 8 of
engine harness.
ECM will use injection
pump speed as back up.
Possible white smoke
and power loss.
F319 ECM Power to real time clock
has been interrupted or is
no longer valid.
Time stamp in ECM
power down data will be
incorrect
F352 Sensor voltage supply Low voltage at engine
speed sensor +5 VDC at
pin 10 of engine harness.
Default value is used.
Engine power will de-rate
to no boost fueling and
loss of protection for oil
pressure, intake boost
pressure and intake air
temp.
F361 VP44 fuel system high
current.
High current at the VP44
pump control valve.
Fueling to injectors is
stopped and engine shuts
down.
F362 VP44 fuel system open Low or no current at the
VP44 pump control valve.
Engine will lose power
and may shut down.
F363 VP44 fuel system feed
back error.
No fuel control valve
movement detected by the
controller.
Engine power loss.
F364 VP44 fuel system
communication error
No communication or
invalid data transfer on
data buss between ECM
and FPCM at pins 4 and 13
of engine harness.
Engine will run at back up
mode set speed when
throttle is off idle.
F365 VP44 fuel system low Low voltage at VP44
controller supply voltage
circuit.
Engine may lose power
and may shut down.
F366 VP44 fuel system
measuring error
Fuel pump controller
voltage not within 6 to 24
VDC.
Engine will lose power
and may shut down.
