MONITOR SEQUENCE:
None
EXECUTION FREQUENCY:
Always Enabled
TYPICAL DURATION:
Five Seconds
DASH LAMPS:
MIL
ENGINE REACTION:
None
VERIFICATION:
1. When ambient temperature greater than -8°C (17.6°F).
2. Barometric pressure greater than 755 mbar.
3. Engine has not been in regeneration mode for greater than five minutes.
4. Warm up engine such that coolant temperature greater than 65°C (149°F).
5. Run vehicle.
6. Varying throttle to vary EGR flow.
7. Insuring engine is operating in closed-loop EGR control and CAC outlet temperature greater than 0°C (32°F).
PROBABLE CAUSES:
1. If any voltage codes exist, fix those first.
2. EGR valve actuator pull rod.
3. EGR actuator.
4. EGR valve.
