4. ENGINE FAULT CODE
J1939 Code
Description
Effect and Action
27-3
Engine Exhaust Gas Recirculation
Valve Position Sensor : Voltage
Above Normal
The Electronic Control Module (ECM) detects the following
conditions:
The signal voltage from the position sensor on the NOx
Reduction System (NRS) valve is greater than 4.8 VDC for
0.1 seconds.
The warning lamp will come on. The ECM will log the
diagnostic Zcode. The NRS valve will be fully closed while
the code is active.
The engine will be derated.
Valve Position Sensor - Test
27-4
Engine Exhaust Gas Recirculation
Valve Position Sensor : Voltage Below
Normal
The ECM detects the following conditions:
The signal voltage from the NRS valve position sensor is
less than 0.2 VDC for 0.1 seconds.
The warning lamp will come on. The ECM will log the
diagnostic code. The NRS valve will be fully closed while
the code is active. The engine will be derated.
Valve Position Sensor - Test
29-2
Accelerator Pedal Position 2 : Erratic,
Intermittent, or Incorrect (Engines
equipped with a throttle switch)
The Electronic Control Module (ECM) detects the following
condition:
There is an invalid combination of positions for the multi-
position switch.
If equipped, the warning light will come on.
The ECM will log the diagnostic code.
Throttle Switch Circuit - Test
29-2
Accelerator Pedal Position 2 : Erratic,
Intermittent or Incorrect (Engines
equipped with an analog throttle)
Analog Throttle Position Sensor Circuit - Test
29-3
Accelerator Pedal Position 2 : Voltage
Above Normal (Engines equipped
with an analog throttle)

following conditions:
The ECM has been powered for 3 seconds.
Diagnostic code 168-4 is not active.
3509 (262) codes are not active.
The setting for the upper diagnostic limit has been
exceeded for one second.
If equipped, the warning lamp will come on. The diagnostic
code will be logged.
Analog Throttle Position Sensor Circuit - Test
29-3
Accelerator Pedal Position 2 : Voltage
Above Normal (Engines equipped
with a digital throttle)
The Electronic Control Module (ECM) detects the following
conditions:
The ECM has been powered for 3 seconds.
Diagnostic code 168-4 is not active.
There are no active 678 or 41 codes.
The setting for the upper diagnostic limit has been
exceeded for one second.
If equipped, the warning lamp will come on. The diagnostic
code will be logged.
