DTC P0665 [MZR-CD (RF Turbo)]

BME010200102286

DTC P0665

Intake shutter solenoid valve (full) circuit voltage high input

DETECTION CONDITION

• The PCM monitors the output signal to the intake shutter solenoid valve (full) when intake shutter solenoid valve (full) is on. If the intake shutter solenoid valve (full) voltage is more than 7.8 V when the intake shutter solenoid valve (full) is on, the PCM determines that there is a malfunction in the intake shutter solenoid valve (full) 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 (full) malfunction
• Connector or terminal malfunction
• Short to power circuit in wiring harness between intake shutter solenoid valve (full) terminal B and PCM terminal 100
• 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".
4
INSPECT INTAKE SHUTTER SOLENOID VALVE (FULL) 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 8.
No
Go to the next step.
5
INSPECT INTAKE SHUTTER SOLENOID VALVE (FULL) CIRCUIT FOR SHORT TO POWER
• Turn the engine switch off.
• Inspect the voltage between intake shutter solenoid valve (full) terminal B and body GND.
• Is the voltage B+?
Yes
Repair or replace wiring harness for a short to power supply, then go to Step 8.
No
Go to the next step.
6
INSPECT INTAKE SHUTTER SOLENOID VALVE (FULL)
• Inspect the intake shutter solenoid valve (full).
•  Is there any malfunction?
Yes
Replace the intake shutter solenoid valve, then go to Step 8.
No
Go to the next step.
7
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 the next step.
No
Go to the next step.
8
VERIFY TROUBLESHOOTING OF DTC P0665 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.
9
VERIFY AFTER REPAIR PROCEDURE
• Perform the Repair Verification Drive Mode.
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
Troubleshooting completed.
