2. 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. Petroleum substances
inside the valve air 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. FUEL TANK CAP ASSY
(a) Visually check if cap and/or gasket are deformed or dam-
aged.
If necessary, repair or replace the cap.
4. VACUUM SWITCHING VALVE ASSY NO.1
(a) Inspect VSV for open circuit.
(1) Using an ohmmeter, check that there is continuity
between the terminals.
Resistance: 30 – 34 Ω at 20C (68F)
If there is no continuity, 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.
