DTC P2009 [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)]

id0102c4810400

DTC P2009

Variable swirl control (VSC) solenoid valve circuit low input
DETECTION CONDITION
•  The PCM monitors the output signal to the VSC solenoid valve. If the voltage of the VSC solenoid valve is low even if the VSC solenoid valve is off, the PCM determines that there is a malfunction in the VSC solenoid valve control circuit.
POSSIBLE CAUSE
•  VSC solenoid valve malfunction
•  Short to ground between VSC solenoid valve terminal B and PCM terminal 181
•  Connector or terminal malfunction
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related service information availability.
•  Is any related service information available?
Yes
Perform repair or diagnosis according to the available service information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT?
•  Connect the M-MDS to the DLC-2.
•  Clear the DTC from PCM memory using the M-MDS.
•  Start the engine.
•  Is the PENDING CODE for this DTC present?
Yes
Go to the next step.
No
Intermittent concern exists.
Perform the “INTERMITTENT CONCERNS TROUBLESHOOTING”.
4
INSPECT POOR CONNECTION OF VSC SOLENOID VALVE CONNECTOR
•  Turn the engine switch off.
•  Disconnect the VSC solenoid valve connector.
•  Inspect for poor connection (such as damaged/pulled-out terminals, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the suspected terminal, go to Step 8.
No
Go to the next step.
5
INSPECT VSC SOLENOID VALVE
•  Inspect the VSC solenoid valve.
•   Is the VSC solenoid valve normal?
Yes
Go to the next step.
No
Replace the VSC solenoid valve, go to Step 8.
6
INSPECT VSC SOLENOID VALVE FOR SHORT TO GROUND
•  Turn the engine switch to the ON position (Engine off).
•  Measure the voltage between VSC solenoid valve terminal B (wiring harness-side) and body ground.
•  Is the voltage B+?
Yes
Repair or replace the wiring harness for a short to power supply, go to Step 8.
No
Go to the next step.
7
INSPECT POOR CONNECTION OF PCM CONNECTOR
•  Turn the engine switch off.
•  Inspect for poor connection (such as damaged/pulled-out terminals, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the suspected terminal, go to the next step.
No
Go to the next step.
8
VERIFY TROUBLESHOOTING OF DTC P2009 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from PCM memory using the M-MDS.
•  Start the engine.
•  Is the PENDING CODE for this DTC present?
Yes
Replace the PCM, go to the next step.
No
Go to the next step.
9
VERIFY AFTER REPAIR PROCEDURE
•  Perform the Repair Verification Drive Mode.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)])
No
Troubleshooting completed.
