EVAP CANISTER INSPECTION
WARNING:
DO NOT SUCK nozzles on EVAP canister. Fuel vapor inside
EVAP canister is harmful.
1) Disconnect vacuum hoses from EVAP canister and remove
EVAP canister.
2) When air is blown into tank pipe, there should be no restriction
of flow through purge pipe and air pipe.
If operation differs from above description, EVAP canister must
be replaced.
3) Install EVAP canister and connect hoses to canister.
TANK PRESSURE CONTROL VALVE INSPECTION
WARNING:
DO NOT SUCK air through tank pressure control valve.
Fuel vapor inside the valve is harmful.
1) Remove tank pressure control valve.
2) Air should pass through valve smoothly from fuel tank side
(black side of tank pressure control valve) to orange side when
blown hard.
3) From orange side, even when blown softly, air should come out
of black side.
4) If air doesn’t pass though valve in step 2) or hard blow is required
in step 3), replace tank pressure control valve.
5) Install tank pressure control valve.
NOTE:
When connecting tank pressure control valve between
hoses, refer to figure at the left for installing direction.
PCV SYSTEM
NOTE:
Be sure to check that there is no obstruction in PCV valve or
its hoses before adjusting engine idle speed, for obstructed
PCV valve or hose hampers its accurate adjustment.
PCV HOSE INSPECTION
Check hoses for connection, leakage, clog and deterioration.
Replace as necessary.

PCV VALVE INSPECTION
1) Disconnect PCV hose from PCV valve.
2) Run engine at idle.
3) Place your finger over end of PCV valve to check for vacuum.
If there is no vacuum, check for clogged valve. Replace as nec-
essary.
4) After checking vacuum, stop engine and check PCV valve for
sticking.
With engine stopped, connect a new hose to PCV valve for in-
spection.
Blow air into the hose and check that air flows with difficulty from
cylinder head side to intake manifold side.
If air flows without difficulty, valve is stuck in “Open” position. Re-
place PCV valve.
WARNING:
Do not suck air through PCV valve. Petroleum substances
inside the valve and fuel vapor inside the intake manifold
are harmful.
5) After removing the hose, connect PCV hose and clamp securely.
