DTC P2006:00 [L5]: Notes

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

DETECTION CONDITION & POSSIBLE CAUSES

DTC P2006:00	Variable tumble shutter valve stuck closed
DETECTION CONDITION	The PCM monitors mass the variable tumble shutter valve position using the variable tumble position sensor. If the PCM turns the variable tumble solenoid valve off but the variable tumble position still remain close for 5 s (the variable tumble position sensor on), the PCM determines that the variable tumble shutter valve has been stuck closed Diagnostic support note This is a continuous monitor (CCM). The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle FREEZE FRAME DATA is available The DTC is stored in the PCM memory
POSSIBLE CAUSE	Variable tumble solenoid valve connector or terminal malfunction Variable tumble solenoid valve malfunction Variable tumble shutter valve switch connector or terminal malfunction Variable tumble shutter valve switch malfunction Variable tumble shutter valve actuator malfunction (stuck closed) PCM connector or terminal malfunction Short to ground in wiring harness between variable tumble shutter valve switch terminal C and PCM terminal 2R Short to ground in wiring harness between variable tumble solenoid valve terminal B and PCM terminal 2I PCM malfunction
