DTC P2004:00: Notes

DTC P2004:00 (MZR 1.5) DETECTION CONDITION AND POSSIBLE CAUSES

DTC P2004:00	Variable tumble shutter valve stuck open
DETECTION CONDITION	The PCM monitors the variable tumble shutter valve position using the variable tumble shutter valve position sensor. If the PCM turns the variable tumble shutter valve on but the variable tumble shutter valve position still remain open for 5 s (the variable tumble shutter valve position sensor on), the 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 first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	Variable tumble shutter valve actuator connector or terminals malfunction Variable tumble shutter valve actuator malfunction (stuck open) PCM connector or terminals malfunction Short to power supply in wiring harness between variable tumble shutter valve actuator terminal A and PCM terminal 2AL Open circuit in wiring harness between variable tumble shutter valve actuator terminal A and PCM terminal 2AL Variable tumble shutter valve position sensor malfunction PCM malfunction
