DTC P0661 [MZR-CD (RF Turbo)]

BME010200102283

DTC P0661 | Intake shutter solenoid valve (half) circuit low input
--- | ---
DETECTION CONDITION | • The PCM monitors the output signal to the intake shutter solenoid valve (half) when the intake shutter solenoid valve (half) is off. If the intake shutter solenoid valve (half) voltage is less than 7.8 V when the intake shutter solenoid valve (half) off, the PCM determines that there is a malfunction in the intake shutter 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 during the first drive cycle.
• FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.
POSSIBLE CAUSE | • Intake shutter solenoid valve malfunction • Connector or terminal malfunction • Short to GND in wiring harness between intake shutter solenoid valve (half) terminal B and PCM terminal 74 • Open circuit in wiring harness between intake shutter solenoid valve (half) terminal A and PCM control relay terminal C
• Open circuit in wiring harness between intake shutter solenoid valve (half) terminal B and PCM terminal 74
• 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 INTAKE SHUTTER SOLENOID VALVE (HALF) CONNECTOR FOR POOR CONNECTION • Turn the engine switch to the ON position. • Inspect for poor connection (such as damaged/pulled-out terminals, corrosion). • Is the voltage B+? | Yes | Go to the next step.
No | Repair or replace the terminal, then go to Step 10.
5 | INSPECT INTAKE SHUTTER SOLENOID VALVE (HALF) POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT • Turn the engine switch off. • Measure the voltage at intake shutter solenoid valve (half) terminal A. • Is the voltage B+? | Yes | Go to the next step.
No | Repair or replace wiring harness for an open circuit, then go to the next step.
6 | INSPECT INTAKE SHUTTER SOLENOID VALVE (HALF) CIRCUIT FOR SHORT TO GND • Turn the engine switch off. • Inspect for continuity between Intake shutter solenoid valve (half) terminal B and GND. • Is there continuity? | Yes | Repair or replace wiring harness for a short to GND, then go to Step 10.
No | Go to the next step.
7 | INSPECT INTAKE SHUTTER SOLENOID VALVE (HALF) • Inspect the intake shutter solenoid valve (half). (See INTAKE SHUTTER SOLENOID VALVE INSPECTION [MZR-CD (RF Turbo)].) • Is there any malfunction? | Yes | Replace the intake shutter solenoid valve, then go to Step 10.
No | Go to the next step.
8 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • 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 terminal, then go to Step 10.
No | Go to the next step.
9 | INSPECT INTAKE SHUTTER SOLENOID VALVE CIRCUIT FOR OPEN CIRCUIT • Turn the engine switch off. • Inspect for continuity between intake shutter solenoid valve (half) terminal B and PCM terminal 74. • Is there continuity? | Yes | Go to the next step.
No | Repair or replace wiring harness for an open circuit, then go to the next step.
10 | VERIFY TROUBLESHOOTING OF DTC P0661 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, then go to the next step.
No | Go to the next step.
11 | 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.
