DTC P2009:00 [L5]: Notes

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

DETECTION CONDITION & POSSIBLE CAUSES

DTC P2009:00	Variable tumble solenoid valve circuit low input
DETECTION CONDITION	The PCM monitors variable tumble solenoid valve control signal. If the PCM turns variable tumble solenoid valve off but voltage still remains low, the PCM determines that variable tumble solenoid valve circuit has malfunction 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 is available The DTC is stored in the PCM memory.
POSSIBLE CAUSE	Variable tumble solenoid valve connector or terminal malfunction Short to ground in wiring harness between main relay terminal D and variable tumble solenoid valve terminal A Open circuit in wiring harness between main relay terminal D and variable tumble solenoid valve terminal A PCM connector or terminal malfunction Short to ground in wiring harness between variable tumble solenoid valve terminal B and PCM terminal 2I Variable tumble solenoid valve malfunction Open circuit in wiring harness between variable tumble solenoid valve terminal B and PCM terminal 2I PCM malfunction

DTC P2009:00

Variable tumble solenoid valve circuit low input

DETECTION CONDITION

The PCM monitors variable tumble solenoid valve control signal. If the PCM turns variable tumble solenoid valve off but voltage still remains low, the PCM determines that variable tumble solenoid valve circuit has malfunction

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 is available
The DTC is stored in the PCM memory.

POSSIBLE CAUSE

Variable tumble solenoid valve connector or terminal malfunction
Short to ground in wiring harness between main relay terminal D and variable tumble solenoid valve terminal A
Open circuit in wiring harness between main relay terminal D and variable tumble solenoid valve terminal A
PCM connector or terminal malfunction
Short to ground in wiring harness between variable tumble solenoid valve terminal B and PCM terminal 2I
Variable tumble solenoid valve malfunction
Open circuit in wiring harness between variable tumble solenoid valve terminal B and PCM terminal 2I
PCM malfunction
