УКАЗАНИЕ:

Separation of the engine oil dipstick, oil filler cap, PCV hose, etc. may cause the engine to run improperly. Disconnection, looseness or cracks in the parts of the air induction system between the throttle body and cylinder head will allow air suction and cause the engine to run improperly.

Start the engine. Disconnect the vacuum hose as shown in the illustration.

Connect the intelligent tester to the DLC3.

Select the following menus: Powertrain / Active Test / Activate the VSV for EVAP Control.

Check that a vacuum occurs at the VSV port.
