Some 2004-2009 Mazda vehicles may experience a MIL that comes on with DTC P2004 (variable tumble shutter valve stuck open). The cause may be the check valve in the intake manifold vacuum chamber being stuck open. The check valve has now been updated. Applicable models include 2004-2009 Mazda3 with L3 or LF engines, and 2006-2009 Mazda5 vehicles with the L3 engine.
