Description: Low Air Flow
Troubleshooting:
DESCRIPTION:
This fault code sets when the engine is in smoke mode control for an excess amount of time
due to inadequate clean airflow into the engine.
MONITORED PARAMETER:
Smoke mode operation.
TYPICAL ENABLING CONDITIONS:
1. General enabling condition: engine is in smoke mode.
2. Specific Enabling Conditions:
Engine Parameter Min
Engine Coolant Outlet Temperature 65°C (149°F)
Barometric Pressure (mbar) 755
Ambient Temperature -8°C (18°F)
MONITOR SEQUENCE:
None
EXECUTION FREQUENCEY:
Continuous when enabling conditions met.
TYPCIAL DURATION:
13 seconds
DASH LAMPS:
1. MIL
2. CEL
ENGINE REACTION:
Derate 25%
VERIFICATION:
Once engine is at standard operating temperature, operate engine on highway, coast for 30
seconds and then snap throttle and keep throttle at 100% for a minimum of 15 seconds.
POSSIBLE CAUSES:
1. Faulty MCM.
2. Damaged or corroded intake manifold pressure sensor electrical connector.
3. Faulty intake manifold pressure sensor.
4. Faulty EGR Delta Pressure sensor and the pigtail.
5. Faulty DOC inlet pressure sensor.
6. Faulty turbocharger.
7. Faulty ATD.
8. Dirty EGR system components .
9. Faulty hose sensor.
