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 ON but the variable tumble position still remain open (the variable tumble position sensor OFF), the PCM determines that the variable tumble shutter valve has been stuck open.
