Aftertreatment diesel exhaust fluid pressure
3575 sensor - Data valid but above normal operating
4334 range - Moderately severe level. The diesel
16 exhaust fluid dosing unit has detected a
blockage in the diesel exhaust fluid return flow.
Aftertreatment diesel exhaust fluid return valve -
3577
Voltage above normal or shorted to high
4376
source. High signal voltage detected at the
3
aftertreatment diesel exhaust fluid return valve.
Aftertreatment diesel exhaust fluid return valve -
3578
Voltage below normal, or shorted to low source.
4376
Low signal voltage detected at the diesel
4
exhaust fluid return valve.
Aftertreatment SCR catalyst conversion
3582
efficiency - Data valid but below normal
4364
operating range - Moderately severe level. NOx
18
conversion across the SCR catalyst is too low.
Aftertreatment outlet NOx sensor heater -
3583
Abnormal rate of change. The aftertreatment
5031
outlet NOx sensor heater is unable to maintain
10
its normal operating temperature.
Aftertreatment diesel exhaust fluid pressure
3596 sensor - Data erratic, intermittent, or incorrect.
4334 The diesel exhaust fluid pressure sensor has
2 reported a reading too high or low for the
operating conditions.
Aftertreatment Intake NOx sensor heater -
3649
Abnormal rate of change. The aftertreatment
5024
intake NOx sensor heater is unable to maintain
10
its normal operating temperature.
Aftertreatment outlet NOx sensor power supply
3681
- Data erratic, intermittent, or incorrect. The
3228
aftertreatment outlet NOx sensor indicates that
2
the power supply to the sensor is incorrect.
Aftertreatment Intake NOx sensor power supply
3682
- Data erratic, entermittent or encorrect. The
3218
aftertreatment intake NOx sensor indicates that
2
the power supply to the sensor is incorrect.
E
ngine control module calibration memory -
3697
Bad intelligent device or component.
630
Error internal to the ECM related to engine
12
software failures.
Aftertreatment SCR operator inducement -
3712 Data valid but above normal operational range -
5246 Most severe level. Critical SCR related fault
0 codes have been active for an extended period
of time and require immediate attention.
