DTC P2006 [LF]: Notes

DTC P2006 (LF) DETECTION CONDITION AND POSSIBLE CAUSE

DTC P2006	Variable tumble shutter valve stuck closed
DETECTION CONDITION	The PCM monitors mass the variable tumble shutter valve position using the variable tumble shutter valve switch. If the PCM turns the variable tumble solenoid valve off but the variable tumble shutter valve position still remain close (variable tumble shutter valve switch 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 above malfunction condition in two consecutive drive cycles or in one drive cycle while DTC for the same malfunction has been stored in PCM. PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA (Mode 2/Mode 12) is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	Variable tumble shutter valve actuator malfunction (stuck closed) Variable tumble shutter valve switch malfunction Variable tumble shutter valve malfunction (stuck closed) Variable tumble solenoid valve malfunction Variable tumble solenoid valve connector or terminals malfunction Variable tumble shutter valve switch connector or terminals malfunction Short to ground in wiring harness between variable tumble solenoid valve terminal B and PCM terminal 2I Short to ground in wiring harness between variable tumble shutter valve switch terminal A and PCM terminal 2AE PCM connector or terminals malfunction PCM malfunction

Variable tumble shutter valve stuck closed

DETECTION CONDITION

The PCM monitors mass the variable tumble shutter valve position using the variable tumble shutter valve switch. If the PCM turns the variable tumble solenoid valve off but the variable tumble shutter valve position still remain close (variable tumble shutter valve switch 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 above malfunction condition in two consecutive drive cycles or in one drive cycle while DTC for the same malfunction has been stored in PCM.
PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
FREEZE FRAME DATA (Mode 2/Mode 12) is available.
The DTC is stored in the PCM memory.

POSSIBLE CAUSE

Variable tumble shutter valve actuator malfunction (stuck closed)
Variable tumble shutter valve switch malfunction
Variable tumble shutter valve malfunction (stuck closed)
Variable tumble solenoid valve malfunction
Variable tumble solenoid valve connector or terminals malfunction
Variable tumble shutter valve switch connector or terminals malfunction
Short to ground in wiring harness between variable tumble solenoid valve terminal B and PCM terminal 2I
Short to ground in wiring harness between variable tumble shutter valve switch terminal A and PCM terminal 2AE
PCM connector or terminals malfunction
PCM malfunction
