Dodge 2009 Dodge Ram Pickup 2500 - Manual (Page 93)

If the vehicle experiences a sudden loss of engine power
when being driven in heavy snow, rain or when plowing
snow, and the EVIC message center states SERVICE AIR
FILTER is showing a plugged filter, then visually inspect
the air filter for snow/ice build up or extreme water
saturation. If the air filter is not damaged, remove all
snow/ice and reinstall air filter. If the air filter is dam-
aged, replace filter element.
NOTE: The air filter housing contains a Mass Air Flow
sensor. This sensor is critical to proper engine operation
and component longevity. Any damage or modification
to this sensor could result in major engine and/or
exhaust aftertreatment damage. This includes the use of
non-approved air filters. Use only MOPAR
௡ approved air
filters or equivalent.
A visual inspection of the air cleaner filter element is
never recommended under normal circumstances. A
badly restricted element may appear clean while a soiled
element may be quite effective in filtering particles
without restricting air flow. Rely on the Engine Control
Module to determine when a filter change is necessary.
CAUTION!
Many aftermarket performance air filter elements do
not adequately filter the air entering the engine. Use
of such filters can severely damage your engine.
