ON±VEHICLE INSPECTION
1. VISUALLY INSPECT HOSES, CONNECTIONS AND
GASKETS
(a) Check for cracks, leak or damage.
HINT:
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 be-
tween the throttle body and cylinder head will allow air suction
and cause the engine to run improperly.

2. INSPECT VENTILATION VALVE SUB±ASSY
(a) Install clean hose to the PCV valve.
(b) Inspect the PCV valve operation.
(1) Blow air into the cylinder head side, and check that
air passes through easily.
CAUTION:
Do not suck air through the valve. If contains petroleum
substances and is harmful.
(2) Blow air into the intake manifold side, and check
that air passes through with difficulty.
If operation is not as specified, replace the PCV valve.
(c) Remove clean hose from the PCV valve.
3. INSPECT FUEL TANK CAP ASSY

If the resistance is not as specified, replace the VSV.
(b) Inspect the VSV for ground.
(1) Using an ohmmeter, check that there is no continu-
ity between each terminal and the body.
If there is continuity, replace the VSV.
(c) Inspect the VSV operation.
(1) Check that air flows with a little difficulty from port E
to port F.
(2) Apply battery voltage across the terminals.
(3) Check that air flows from port E to port F.
If operation is not as specified, replace the VSV.
