DTC P2009: Notes
DTC P2009 DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P2009 |
Variable swirl solenoid valve control circuit low |
| DETECTION CONDITION |
- PCM monitors the variable swirl solenoid valve control signal. If the PCM turns variable swirl solenoid valve off but the voltage still remains low, the PCM determines that the variable swirl solenoid valve control circuit has a 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.
- DTCs are stored in PCM memory.
|
| POSSIBLE CAUSE |
- Poor connection of connectors at PCM and/or variable swirl solenoid valve
- Short to ground in the wiring harness between variable swirl solenoid valve terminal B and PCM terminal 4K
- Open circuit in the wiring harness between main relay and variable swirl solenoid valve terminal A
- Open circuit in the wiring harness between variable swirl solenoid valve terminal B and PCM terminal 4K
- Variable swirl solenoid valve malfunction
- PCM malfunction
