DTC P2004:00: Notes

DTC DETECTING CONDITION REFERENCE CHART

DTC P2004:00	Variable tumble shutter valve stuck open
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 on but the variable tumble position still remain open for 5 s (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). 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 (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	Variable tumble solenoid valve connector or terminal malfunction Variable tumble shutter valve position sensor connector or terminal malfunction PCM connector or terminal malfunction Short to power supply in wiring harness between variable tumble solenoid valve terminal B and PCM terminal 2I Short to power supply in wiring harness between variable tumble shutter valve position sensor terminal C and PCM terminal 2R Variable tumble solenoid valve malfunction Variable tumble shutter valve actuator malfunction (stuck open) Variable tumble shutter valve position sensor malfunction Open circuit in wiring harness between variable tumble solenoid valve terminal B and PCM terminal 2I Open circuit in wiring harness between variable tumble shutter valve position sensor terminal C and PCM terminal 2R Miss connecting or pull out the vacuum hose PCM malfunction
