Intake System On-Vehicle Inspection

Remove the 2 nuts and V-bank cover.

Inspection procedure when using the intelligent tester.

1. Stop the engine.
   

2. Connect the intelligent tester to the DLC3.
   

3. Start the engine and turn the intelligent tester main switch ON.
   

4. Select the following menus: Powertrain / Engine / Active Test / Activate the VSV for Intake Control. Press the right or left button.
   

5. Make sure that a clicking sound is heard from the intake air control valve when current flows.
   

Inspection procedure when applying voltage between terminals.

1. Disconnect the connector from the intake air control valve.
   

2. Apply battery voltage between terminals 1 (-) and 2 (+) of the intake air control valve. Check that a clicking sound is heard from the intake air control valve.
   

Reinstall the V-bank cover with the 2 nuts.

Remove the 2 nuts and V-bank cover.

Check that the link is moving to confirm that the swirl control valve is operating.

1. After the engine switch is turned off, confirm that the swirl control valve opens between approximately 10° and the fully open position.
   

2. After the engine is started and is idling, confirm that the swirl control valve is fully closed.
   

3. After the engine switch is turned off again, confirm that the swirl control valve opens between approximately 10° and the fully open position.
   

Inspection procedure when using the intelligent tester.

1. Connect the intelligent tester to the DLC3.
   

2. Start the engine and turn the tester main switch ON.
   

3. Select the following menus: Powertrain / Engine / Active Test / Control the SCV Duty Ratio. Press the right or left button.
   

   NOTICE:

   This test procedure must be completed within 10 seconds.





4. Check that the swirl control valve activation link (on the front of the intake manifold) moves to the left and right.
   

Inspection procedure when applying voltage between terminals.

1. Disconnect the connector from the swirl control valve.
   

2. Alternately apply battery voltage to terminals 1 and 2 of the swirl control valve.
   

3. Check that the swirl control valve activation link (on the front of the intake manifold) moves to the left and right.
   

Measure the resistance between the terminals.

Standard resistance:

1 to 19 Ω at 20°C (68°F)
