EVAP Canister Inspection
WARNING:
DO NOT SUCK nozzles on EVAP canister. Fuel vapor inside
EVAP canister is harmful.
1) Check outside of EVAP canister visually.
2) Disconnect vacuum hoses from EVAP canister.
3) Check that there should be no restriction of flow through purge
pipe (2) and air pipe (3) when air is blown (4) into tank pipe (1).
If any faulty condition is found in above inspection replace.
PCV SYSTEM
NOTE:
Be sure to check that there is no obstruction in PCV valve or
its hoses before checking IAC duty, 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 valve (1) from cylinder head cover and install
plug to head cover hole.
2) Run engine at idle.
3) Place your finger over end of PCV valve (1) to check for vacuum.
If there is no vacuum, check for clogged valve. Replace as nec-
essary.
4) After checking vacuum, stop engine and remove PCV valve (1).
Shake valve and listen for the rattle of check needle inside the
valve. If valve does not the rattle, replace valve.
5) After checking, remove plug and install PCV valve (1).

ON-VEHICLE SERVICE
IGNITION SPARK TEST
1) Disconnect injector coupler at throttle body side.
WARNING:
Without disconnection of injector coupler, combustible gas
may come out from spark plug holes during this test and
may get ignited in engine room.
2) Remove spark plugs and connect them to high-tension cords,
and then ground spark plugs.
3) Crank engine and check if each spark plug sparks.
4) If no spark is emitted, inspect high-tension cords, spark plugs,
ignition coil, distributor, etc.
HIGH-TENSION CORDS
1) Remove high-tension cord at ignition coil while gripping its cap.
2) Remove distributor cap installed with high-tension cords.
3) Remove high-tension cord clamp from cylinder head cover.
4) Pull out high-tension cords from spark plugs while gripping each
cap.
CAUTION:

Removal of high-tension cords together with clamps
will be recommended so as not to damage their inside
wire (resistive conductor).

For the same reason, pull out each connection by grip-
ping cap portion.
5) Measure resistance of high-tension cord by using ohmmeter.
High-tension cord resistance: 10 – 22 kΩ/ m (3.0 – 6.7 kΩ/ft)
