2. INSPECT FUEL CUT OFF RPM
(a) Check the operation.
(1) Increase the engine speed to at least 3,500 rpm.
(2) Use a sound scope to check the fuel injector operating noise.
(3) Check that when the throttle lever is released, the fuel injector operation noise stops momentarily
at 2,500 rpm and then resumes at 1,200 rpm.
2,500 rpm: Fuel cut off rpm
1,200 rpm: Fuel return rpm
3. VISUALLY INSPECT HOSES, CONNECTIONS AND
GASKETS
(a) Check the appearance.
(1) Check the engine assembly to see if the indicated
portions by the arrows have cracks, leaks or dam-
age.
HINT:
Separation of the engine oil level gauge, oil filler cap, PCV
hose, etc. may cause the engine to run improperly. Disconnec-
tion, looseness or cracks in the parts of the air induction system
between the throttle body and cylinder head will allow air suc-
tion and cause the engine to run improperly.
If necessary, repair the engine assembly.
4. INSPECT EVAP SYSTEM LINE
(a) Warm up the engine to the normal operating temperature.
(b) Connect the vacuum gauge (EVAP control system test
equipment vacuum gauge) to the EVAP service port on
the purge line. Then stop the engine.
(c) If you have the hand-held tester:
Force the VSV for EVAP to operate.
(1) Connect the hand-held tester to the DLC3.
(2) Start the engine.
(3) Turn the hand-held tester ON.
(4) Use the ACTIVE TEST mode on the hand-held tes-
ter to operate the VSV for EVAP.

(d) If you have no hand-held tester:
Force the VSV for EVAP to operate.
(1) Disconnect the VSV for EVAP connector.
(2) Connect the positive (+) and negative (-) leads of
the battery to the VSV for EVAP terminals.
(3) Start the engine.
(e) Check the vacuum at idle.
Vacuum:
Maintain at 0.368 to 19.713 in.Hg (5 to 268 in.Aq) for
over 5 seconds.
HINT:
If the vacuum does not change, it can be concluded that the
hose which connects the VSV to the service port is loose or
blocked, or the VSV is malfunctioning.
(f) If you have the hand-held tester:
Return to the normal VSV for EVAP.
(1) Stop the engine.
(2) Disconnect the hand-held tester from the DLC3.
(g) If you have no hand-held tester:
Return to the normal VSV for EVAP.
(1) Stop the engine.
(2) Disconnect the positive (+) and negative (-) leads
of the battery from the VSV for EVAP terminals.
(3) Reconnect the VSV for EVAP connector.
(h) Disconnect the vacuum gauge from the EVAP service
port on the purge line.
(i) Connect a pressure gauge to the EVAP service port on
the purge line.

(j) If you have the hand-held tester:
Force the VSV for CCV to operate.
(1) Connect the hand-held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) Turn the hand-held tester ON.
(4) Use the ACTIVE TEST mode on the hand-held tes-
ter to operate the VSV for CCV.
NOTICE:
Do not start the engine during this operation.
HINT:
If the check is not completed within 10 minutes, the forced close
of the VSV for CCV will be tested.
(k) If you have no hand-held tester:
Force the VSV for CCV to operate.
(1) Disconnect the VSV for CCV connector.
(2) Connect the positive (+) and negative (-) leads of
the battery to the VSV for CCV terminals.
(l) Check the pressure.
(1) Add the pressure (13.5 to 15.5 in.Aq) from the
EVAP service port.
Pressure:
2 minutes after the pressure is added, the gauge
should be over 7.7 to 8.8 in.Aq.
HINT:
If you cannot add the pressure, it can be concluded that the
hose which connects the VSV for EVAP canister fuel tank is
slipped off or the VSV is open.
(2) Check if the pressure decreases when the fuel tank
cap is removed while adding the pressure.
HINT:
If the pressure does not decrease when the filler cap is re-
moved, it can be concluded that the hose which connects the
service port to the fuel tank is blocked, etc.
(m) If you have the hand-held tester:
Return to the normal VSV for CCV operation.
(1) Turn the ignition switch ON.
(2) Disconnect the hand-held tester from the DLC3.
(n) If you have no hand-held tester:
Return to the normal VSV for CCV operation.
(1) Disconnect the positive (+) and negative (-) leads
of the battery to the VSV for CCV terminals.
(2) Reconnect the VSV for CCV connector.

(o) Disconnect the pressure gauge from the EVAP service
port on the purge line.
5. CHECK AIR TIGHTNESS IN FUEL TANK AND FILLER
PIPE
(a) Check the operation.
(1) Remove the fuel tank (see page 11-28).
(2) Remove the fuel tank vent hose from the fuel tank
(see page 11-28).
(3) Connect the pressure gauge to the fuel tank vent
hose port of the fuel tank.
(4) Apply pressure to the fuel tank, so that the internal
pressure of the fuel tank is 4 kPa (41 gf/cm
2, 0.58
psi).
(5) Check that the internal fuel tank pressure is main-
tained for 1 minute.
(6) Check the connected portions of each hose and
pipe.
(7) Check the installed parts on the fuel tank.
If there is no abnormality, replace the fuel tank and fuel tank filler
pipe.
(8) Reinstall the fuel tank vent hose to the fuel tank (see
page 11-28).
(9) Reinstall fuel tank (see page 11-28).
6. INSPECT FUEL CUT OFF VALVE AND FILL CHECK
VA LV E
(a) Check the operation.
(1) Remove the fuel tank (see page 11-28).
(2) Remove the fuel tank vent hose from the fuel tank
(see page 11-28).
(3) Connect the pressure gauge to the fuel tank vent
hose port of the fuel tank.
(4) Fully fill the fuel tank with fuel.
HINT:
In the condition that the fuel is full, there is no ventilation as the
float valve of the fill check valve is closed.
(5) Install the fuel suction w/ pump & gauge tube (see
page 11-20).
(6) Securely cover the fuel pump tube, fuel tube No. 1
port and fuel tank to filler pipe port with vinyl or plas-
tic bags to perform the accurate pressure test.
(7) Apply 4 kPa (41 gf/cm
2, 0.58 psi) of pressure to the
fuel tank vent hose port of the fuel tank.
