Fault code
(Lamp)
Reason Effect
239
(Orange)
Engine position sensor main supply
Out of range high.
Error.
•
•
—
261
(Orange)
Engine Fuel Temperature
Data valid but above normal operation range.
Moderately severe level. Engine fuel
temperature 1 signal indicates engine fuel
temperature is above engine protection
warning limit.
•
•
Calibration dependent progressive power
and speed derate and engine shutdown with
increasing time after alert.
271
(Orange)
Fuel pump pressurizing assembly 1 circuit
Voltage below normal or shorted to low
source. Low signal voltage detected at the fuel
pump pressurizing assembly 1 circuit.
•
Engine will run poorly at idle. Engine will have
low power. Fuel pressure will be higher than
commanded.
272
(Orange)
Fuel pump pressurizing assembly 1 circuit
Voltage above normal or shorted to high
source. High signal voltage or open circuit
detected at the fuel pump pressurizing
assembly 1 circuit.
•
Engine will not run or engine will run poorly.
281
(Orange)
APC diesel cylinder pressure imbalance error
A pumping imbalance between the front and
rear pumping plungers has been detected.
•
Engine will not run or possible low power.
285
(Orange)
SAE J1939 multiplexing PGN timeout error
Abnormal update rate. The ECM did not
receive a multiplexed message from vehicle
electronic control unit within the time limit or
did not receive it at all.
•
One or more multiplexed devices will not
operate properly. One or more symptoms will
occur.
286
(Orange)
SAE J1939 multiplexing configuration error
Out of calibration. The ECM expected
information from a multiplexed device but
only received a portion of the necessary
information.
•
At least one multiplexed device will not operate
properly.
287
(Orange)
SAE J1939 multiplexed accelerator pedal or
lever sensor system
Received network data in error. The vehicle
electronic control unit detected a fault with its
accelerator pedal.
•
Engine may only idle or engine will not
accelerate to full speed.
288
(Red)
SAE J1939 multiplexing remote accelerator
pedal or lever position sensor circuit
Received network data in error. The vehicle
electronic control unit detected a fault with
remote accelerator.
•
The engine will not respond to the remote
throttle. Engine may only idle. The primary or
cab accelerator may be able to be used.
295
(Orange)
Ambient air pressure sensor
Error detected at initial start. The ambient air
pressure sensor is reading an erratic value
when starter switch is turned to ON position.
•
Engine power derate.
322
(Orange)
Injector solenoid driver cylinder 1 circuit
Current below normal or open circuit. High
resistance or no current detected at Number 1
injector driver or return pin.
•
Engine can misfire or possibly run rough.
323
(Orange)
Injector solenoid driver cylinder 5 circuit
Current below normal or open circuit. High
resistance or no current detected at number 5
injector driver or return pin.
•
Engine can misfire or possibly run rough.
