P2006 MAZDA Description
The Powertrain Control Module (PCM) monitors mass the variable tumble shutter valve using the variable tumble position sensor. If the PCM turn the variable tumble solenoid valve OFF but the variable tumble position still remain closed (the variable tumble position sensor ON), the PCM determines that the variable tumble shutter valve has been stuck closed.
