(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.

(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.
