DTC P0661 [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)]

id0102c4821700

DTC P0661

Intake shutter solenoid valve (full close) control circuit low input
DETECTION CONDITION
•  The PCM monitors the intake shutter solenoid valve (full close) control signal at PCM terminal 152. If the PCM turns the intake shutter solenoid valve (full close) off but the voltage at PCM terminal 152 remains low, the PCM determines that intake shutter solenoid valve (full close) circuit has a malfunction (circuit short to ground).
POSSIBLE CAUSE
•  Intake shutter solenoid valve malfunction
•  Short to ground in wiring harness between intake shutter solenoid valve (full close) terminal B and PCM terminal 152
•  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 the PCM memory using the M-MDS.
•  Run the vehicle under the FREEZE FRAME DATA stored condition.
•  Is the same DTC present?
Yes
Go to the next step.
No
Intermittent concern exists.
Perform the “INTERMITTENT CONCERNS TROUBLESHOOTING”.
(See INTERMITTENT CONCERN TROUBLESHOOTING [WL-C, WE-C].)
4
INSPECT INTAKE SHUTTER SOLENOID VALVE (FULL CLOSE) CONNECTOR FOR POOR CONNECTION
•  Turn the engine switch off.
•  Disconnect the intake shutter solenoid valve (full close).
•  Inspect for poor connection (damaged/pulled-out pins, corrosion, etc.).
•  Is there malfunction?
Yes
Repair or replace the terminal, then go to Step 8.
No
Go to the next step.
5
INSPECT INTAKE SHUTTER SOLENOID VALVE (FULL CLOSE) MALFUNCTION
•  Perform intake shutter solenoid valve (full close) inspection.
•  Is intake shutter solenoid valve normal?
Yes
Go to the next step.
No
Replace the intake shutter solenoid valve (full close), then go to step 8.
6
INSPECT INTAKE SHUTTER SOLENOID VALVE CONTROL CIRCUIT FOR SHORT TO GROUND
•  Inspect for continuity between intake shutter solenoid valve (full close) valve terminal B (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Repair or replace the wiring harness for short to ground, then go to Step 8.
No
Go to the next step.
7
INSPECT PCM CONNECTOR FOR POOR CONNECTION
•  Disconnect the PCM connector.
•  Inspect for poor connection at terminal 152. (damaged/pulled-out pins, corrosion, etc.).
•  Is there malfunction?
Yes
Repair the terminal, then go to the next step.
No
Go to the next step.
8
VERIFY TROUBLESHOOTING OF DTC P0661 COMPLETED
•  Turn the engine switch off.
•  Make sure to reconnect all disconnected connectors.
•  Turn the engine switch to the ON position (Engine off).
•  Clear the DTC from the memory using the M-MDS.
•  Run the vehicle under the FREEZE FRAME DATA stored condition.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [WL-C, WE-C].)
(See PCM REMOVAL/INSTALLATION (U.K. Specs.) [WL-C, WE-C].)
No
Go to the next step.
9
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “After Repair Procedure”.
•  Are any DTC present?
Yes
Go to the applicable DTC troubleshooting.
(See DTC TABLE [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)].)
No
Troubleshooting completed.
