DTC P2009:00: Notes

DTC P2009:00 (L3 WITH TC) DETECTION CONDITION & POSSIBLE CAUSES

DTC P2009:00	Variable swirl solenoid valve control circuit low input
DETECTION CONDITION	The PCM monitors the variable swirl solenoid valve control signal. If the PCM turns the variable swirl solenoid valve off but the voltage still remains low for 5 s , the PCM determines that the variable swirl solenoid valve control circuit has a 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 first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	Variable swirl solenoid valve connector or terminals malfunction Variable swirl solenoid valve malfunction Short to ground or open circuit in variable swirl solenoid valve power supply circuit Short to ground in wiring harness between main relay terminal C and variable swirl solenoid valve terminal A ENG INJ 15 A fuse malfunction Open circuit in wiring harness between main relay terminal C and variable swirl solenoid valve terminal A Short to ground in wiring harness between variable swirl solenoid valve terminal B and PCM terminal 2AS PCM connector or terminals malfunction Open circuit in wiring harness between variable swirl solenoid valve terminal B and PCM terminal 2AS PCM malfunction

DTC P2009:00

Variable swirl solenoid valve control circuit low input

DETECTION CONDITION

The PCM monitors the variable swirl solenoid valve control signal. If the PCM turns the variable swirl solenoid valve off but the voltage still remains low for 5 s , the PCM determines that the variable swirl solenoid valve control circuit has a 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 first drive cycle.
FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
The DTC is stored in the PCM memory.

POSSIBLE CAUSE

Variable swirl solenoid valve connector or terminals malfunction
Variable swirl solenoid valve malfunction
Short to ground or open circuit in variable swirl solenoid valve power supply circuit
- Short to ground in wiring harness between main relay terminal C and variable swirl solenoid valve terminal A
- ENG INJ 15 A fuse malfunction
- Open circuit in wiring harness between main relay terminal C and variable swirl solenoid valve terminal A
Short to ground in wiring harness between variable swirl solenoid valve terminal B and PCM terminal 2AS
PCM connector or terminals malfunction
Open circuit in wiring harness between variable swirl solenoid valve terminal B and PCM terminal 2AS
PCM malfunction
