DTC P0665 [WL-C, WE-C]

id0102b9956000

DTC P0665

Intake shutter solenoid valve (half open) control circuit high input
DETECTION CONDITION
•  The PCM monitors the intake shutter solenoid valve (half open) control signal at PCM terminal 155. If the PCM turns the intake shutter solenoid valve (half open) on, but the voltage at PCM terminal 155 remains high, the PCM determines that the intake shutter solenoid valve (half open) circuit has a malfunction (circuit short to power supply).
POSSIBLE CAUSE
•  Connector or terminal malfunction
•  Intake shutter solenoid valve (half open) malfunction
•  Short to power supply in wiring harness between intake shutter solenoid valve (half open) terminal B and PCM terminal 155
•  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
INSPECT INTAKE SHUTTER SOLENOID VALVE (HALF OPEN) CONNECTOR FOR POOR CONNECTION
•  Turn the engine switch off.
•  Disconnect the intake shutter solenoid valve (half open) connector.
•  Inspect for poor connection (damaged/pulled-out pins, corrosion, etc.).
•  Is there malfunction?
Yes
Repair or replace the terminal, then go to Step 7.
No
Go to the next step.
4
INSPECT INTAKE SHUTTER SOLENOID VALVE (HALF OPEN) MALFUNCTION
•  Perform intake shutter solenoid valve (half open) inspection.
•  Is the intake shutter solenoid valve (half open) normal?
Yes
Go to the next step.
No
Replace the intake shutter solenoid valve (half open), then go to Step 7.
5
INSPECT PCM CONNECTOR FOR POOR CONNECTION
•  Turn the engine switch off.
•  Disconnect the PCM connector.
•  Inspect for poor connection at terminal 155. (such as damaged/pulled-out pins, corrosion).
•  Is there malfunction?
Yes
Repair the terminal, then go to Step 7.
No
Go to the next step.
6
INSPECT INTAKE SHUTTER SOLENOID VALVE (HALF OPEN) CONTROL CIRCUIT SHORT TO POWER SUPPLY
•  Turn the engine switch to the ON position (Engine off).
•  Measure the voltage between intake shutter solenoid valve (half open) terminal B (wiring harness-side) and body ground.
•  Is the voltage B+?
Yes
Repair or replace the wiring harness for short to power supply, then go to the next step.
No
Go to the next step.
7
VERIFY TROUBLESHOOTING OF DTC P0665 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].)
No
Go to the next step.
8
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].)
No
Troubleshooting completed.
