DTC P2004: Notes

DTC P2004 DETECTION CONDITION AND POSSIBLE CAUSES

DTC P2004	Variable tumble shutter valve stuck open
DETECTION CONDITION	PCM monitors mass the variable tumble shutter valve position using the variable tumble position sensor. If PCM turns the variable tumble solenoid valve on but the variable tumble position still remain open (the variable tumble position sensor off), PCM determines that the variable tumble shutter valve has been stuck open. Diagnostic support note This is a continuous monitor (CCM). 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 shutter valve actuator malfunction (stuck open) Miss connecting or pull out the vacuum hose Variable tumble solenoid valve malfunction Variable tumble shutter valve switch malfunction Open circuit in wiring harness between the variable tumble shutter valve switch terminal C and the PCM terminal 2AE Short to power in wiring harness between the variable tumble shutter valve switch terminal C and the PCM terminal 2AE Open circuit in wiring harness between the variable tumble solenoid valve terminal B and the PCM terminal 2AI Short to power in wiring harness between the variable tumble solenoid valve terminal B and the PCM terminal 2AI PCM malfunction
