DTC P0662
A6E397001088W04
5 INSPECT VIS CONTROL SOLENOID VALVE
CONTROL CIRCUIT FOR SHORT TO GROUND
• Inspect continuity between VIS control
solenoid valve terminal A (harness-side) and
body ground.
• Is there continuity?
Yes Repair or replace harness for short to ground, then go to
Step 8.
No Go to next step.
6 INSPECT PCM CONNECTOR FOR POOR
CONNECTION
• Disconnect PCM connector.
• Inspect for poor connection at terminal 4R.
(damaged/pulled-out pins, corrosion, etc.).
• Is there malfunction?
Yes Repair terminal, then go to Step 8.
No Go to next step.
7 INSPECT VIS CONTROL SOLENOID VALVE
CONTROL CIRCUIT FOR OPEN
• Inspect for continuity between VIS control
solenoid valve terminal B (harness-side) and
PCM terminal 4R (harness-side).
• Is there continuity?
Yes Go to next step.
No Repair or replace harness for open, then go to next step.
8 VERIFY TROUBLESHOOTING OF DTC P0661
COMPLETED
• Make sure to reconnect all disconnected
connectors.
• Turn ignition key to ON (Engine OFF).
• Clear DTC from PCM memory using WDS or
equivalent.
• Perform KOEO/KOER self-test.
(See F66 KOEO/KOER SELF-TEST.)
• Is same DTC present?
Yes Replace PCM, then go to next step.
(See F43 PCM REMOVAL/INSTALLATION.)
No Go to next step.
9 VERIFY AFTER REPAIR PROCEDURE
• Perform After Repair Procedure.
(See F66 AFTER REPAIR PROCEDURE.)
• Is there any DTC present?
Yes Go to applicable DTC troubleshooting.
(See F67 DTC TABLE.)
No Troubleshooting completed.
STEP INSPECTION ACTION
DTC P0662 Variable intake-air system (VIS) control solenoid valve circuit high input
DETECTION
CONDITION
• PCM monitors VIS control solenoid valve control signal at PCM terminal 4R. If PCM turns VIS control
solenoid valve on but voltage at PCM terminal 4R still remains high, PCM determines that VIS control
solenoid valve circuit has malfunction.
POSSIBLE
CAUSE
• VIS control solenoid valve malfunction
• Short to power circuit between VIS control solenoid valve terminal B and PCM terminal 4R
• Shorted VIS control solenoid valve or PCM connector
• PCM malfunction
