DTC P2009: Notes

DTC P2009 [L3] CHART

DTC P2009	Variable tumble solenoid valve circuit low input
DETECTION CONDITION	The PCM monitors variable tumble solenoid valve control signal at PCM terminal 2AI. If the PCM turns variable tumble solenoid valve off but voltage at PCM terminal 2AI still remains low, the PCM determines that variable tumble solenoid valve circuit has malfunction. 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	Poor connection of connectors at PCM and/or variable tumble solenoid valve Short to ground in wiring harness between variable tumble solenoid valve terminal B and PCM terminal 2AI Open circuit in wiring harness between main relay and variable tumble solenoid valve terminal A Open circuit in wiring harness between variable tumble solenoid valve terminal B and PCM terminal 2AI Variable tumble solenoid valve malfunction PCM malfunction
