6. Barometric Pressure Greater Than 755 mbar.
7. Engine must have not been in regeneration mode for greater than Five minutes.

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.
