EVAP CANISTER PURGE INSPECTION
NOTE:
Before inspection, check to make sure that gear shift lever is
in neutral position (with A / T model, selector lever in “P” range)
and that parking brake lever is pulled all the way up.
1) Disconnect purge hose from EVAP canister.
2) Place finger against the end of disconnected hose and check
that vacuum is not felt there when engine is cool and running at
idle speed.
3) Connect purge hose to EVAP canister and warm up engine to
normal operating temperature.
4) Disconnect purge hose from EVAP canister.
5) Also check that vacuum is felt when engine is running at idle
speed.
NOTE:
The EVAP canister purge system does not perform purging
(vacuum is not detected at the purge hose) unless the en-
gine is sufficiently warmed up and the heated oxygen sen-
sor is activated fully. Also, when the purge hose is discon-
nected in Step 4), the air is drawn into the purge line. As a
result, ECM detects a change in the purge gas concentra-
tion and sometimes stops purging but this indicates noth-
ing abnormal.
If check result is not satisfactory, check vacuum passage, hoses,
EVAP canister purge valve, wire harness and ECM.
VACUUM PASSAGE INSPECTION
Start engine end run it at idle speed. Disconnect vacuum hose from
EVAP canister purge valve. With finger placed against hose discon-
nected, check that vacuum is applied.
If it is not applied, clean vacuum passage by blowing compressed
air.
VACUUM HOSE INSPECTION
Check hoses for connection, leakage, clog and deterioration. Re-
place as necessary.

EVAP CANISTER PURGE VALVE INSPECTION
WARNING:
Do not suck the air through valve. Fuel vapor inside valve
is harmful.
1) With the ignition switch OFF position, disconnect coupler from
EVAP canister purge valve.
2) Check resistance between two terminals of EVAP canister
purge valve.
Resistance of EVAP canister purge valve:
33 – 39 Ω at 20C (68F)
If resistance is as specified, proceed to next operation check.
If not, replace.
3) Disconnect vacuum hoses from intake manifold and its pipe.
4) With coupler disconnected, blow into pipe “A”. Air should not
come out of pipe “B”.
5) Connect 12 V-battery to EVAP canister purge valve terminals.
In this state, blow pipe “A”.
Air should come out of pipe “B”.
If check result is not as described, replace canister purge valve.
6) Connect vacuum hoses.
7) Connect EVAP canister purge valve coupler securely.

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.
