DTC P0662 [L3]

BME010200600203

DTC P0662 | VIS control solenoid valve circuit high input
--- | ---
DETECTION CONDITION | • The PCM monitors VIS control solenoid valve control signal at PCM terminal 4R. If the PCM turns the VIS control solenoid valve on but voltage at PCM terminal 4R still remains high, the PCM determines that the VIS control solenoid valve circuit has malfunction. Diagnostic support note
• This is a continuous monitor (CCM).
• MIL illuminates if 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 PCM detects the above malfunction condition.
• FREEZE FRAME DATA is available.
• DTC is stored in the PCM memory.
POSSIBLE CAUSE | • VIS control solenoid valve malfunction • Short to power circuit between VIS control solenoid valve terminal B and PCM terminal 4R • Connector or terminal malfunction • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | PERFORM DTC CONFIRMATION PROCEDURE • Perform DTC CONFIRMATION PROCEDURE. (See DTC CONFIRMATION PROCEDURE [L3].) • Is same DTC present? | Yes | Go to the next step.
No | Intermittent concern exists. Go to INTERMITTENT CONCERN TROUBLESHOOTING procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING [L3].)
2 | INSPECT VIS CONTROL SOLENOID VALVE CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the VIS control solenoid valve connector. • Inspect for poor connection (damaged/pulled-out pins, corrosion, etc.). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 6.
No | Go to the next step.
3 | INSPECT VIS CONTROL SOLENOID VALVE MALFUNCTION • Perform VIS control solenoid valve inspection. (See VARIABLE INTAKE-AIR SYSTEM (VIS) CONTROL SOLENOID VALVE INSPECTION [L3].) • Is the VIS solenoid valve normal? | Yes | Go to the next step.
No | Replace the VIS control solenoid valve, then go to Step 6.
4 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect PCM connector. • Inspect for poor connection at terminal 4R. (damaged/pulled-out pins, corrosion, etc.). • Is there any malfunction? | Yes | Repair the terminal, then go to Step 6.
No | Go to the next step.
5 | INSPECT VIS CONTROL SOLENOID VALVE CONTROL CIRCUIT SHORT TO POWER • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between VIS control solenoid valve terminal B (wiring harness-side) and body ground. • Is the voltage B+? | Yes | Repair or replace the wiring harness for open circuit, then go to the next step.
No | Go to the next step.
6 | VERIFY TROUBLESHOOTING OF DTC P0662 COMPLETED • Make sure to reconnect all disconnected connectors. • Turn the ignition switch to the ON position (Engine off). • Clear the DTC from the PCM memory using the WDS or equivalent. • Perform KOEO/KOER self-test.
(See KOEO/KOER SELF-TEST PROCEDURE [L3].)
• Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [L3].)
No | Go to the next step.
7 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [L3].) • Is there any DTC present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [L3].)
No | Troubleshooting completed.
