DTC P2009 [MZR-CD (RF Turbo)]

BME010202000204

DTC P2009 | Variable swirl control (VSC) solenoid valve circuit high input
--- | ---
DETECTION CONDITION | • The PCM monitors the output signal to the variable swirl control solenoid valve. If the voltage of the variable swirl control solenoid valve is more than 7.8 V when the variable swirl control solenoid valve is on, the PCM determines that there is a malfunction in the variable swirl control solenoid valve control circuit. Diagnostic support note
• 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.
• FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.
POSSIBLE CAUSE | • VSC solenoid valve malfunction • Short to power supply between VSC solenoid valve terminal B and PCM terminal 101 • 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 REPAIR INFORMATION AVAILABILITY • Verify related service repair information availability. • Is any related repair information available? | Yes | Perform repair or diagnosis according to the available repair 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 WDS or equivalent to the DLC-2. • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine. • Is the PENDING CODE for this DTC present? | Yes | Go to the next step.
No | Intermittent concern exists. Perform the "INTERMITTENT CONCERN TROUBLESHOOTING". (See INTERMITTENT CONCERN TROUBLESHOOTING [MZR-CD (RF Turbo)].)
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. (See VARIABLE SWIRL CONTROL (VSC) SOLENOID VALVE INSPECTION [MZR-CD (RF Turbo)].) • 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 POWER • 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 the PCM memory using the WDS or equivalent. • 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. (See OBD DRIVE MODE [MZR-CD (RF Turbo)].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZR-CD (RF Turbo)].)
No | Troubleshooting completed.
