In the condition that the fuel fuel is full, as the float value of the
fill check valve is closed and has no ventilation, it is necessary
to check the fuel amount (volume).
(d) Check if there is any struck in the vent line hose and EVAP
line hose.
If there is no stuck in hoses, replace the fuel cutoff valve and fill
check valve.
(e) Reconnect the purge line hose and EVAP line hose to the
charcoal canister.
7. CHECK AIR INLET LINE
(a) Disconnect the air inlet line hose from the charcoal canis-
ter.
(b) Check that there is ventilation in the air inlet line.
(c) Reconnect the air inlet line hose to the charcoal canister.
8. REMOVE CHARCOAL CANISTER ASSEMBLY
(a) Disconnect the VSV connector.
(b) Disconnect the vapor pressure sensor connector.
(c) Disconnect the purge line hose, EVAP line hose and air
inlet line hose from the charcoal canister.
(d) Disconnect the vent line hose from the charcoal canister.
(1) Push the connector deep inside.
(2) Pinch portion A.
(3) Pull out the connector.
(e) Remove the 2 charcoal canister mounting bolts.
(f) Remove the vapor pressure sensor mounting bolt.
(g) Remove the charcoal canister assembly.
9. INSPECT CHARCOAL CANISTER
(a) Visually check the charcoal canister for cracks or dam-
age.
(b) Inspect the charcoal canister operation.
(1) Plug the vent port with a cap.
(2) While holding the purge port closed, blow air (1.76
kPa, 18 gf/cm
2, 0.26 psi) into the EVAP port and
check that air flows from the air drain port.

(3) While holding the purge port and the air drain port
closed, blow air (1.76 kPa, 18 gf/cm
2, 0.26 psi) into
the EVAP port and check that air does not flow from
the air inlet port.
(4) Apply vacuum (3.43 kPa, 25.7 mmHg, 1.01 in.Hg)
to the purge port, check that the vacuum does not
decrease when the air inlet port is closed, and
check that the vacuum decreases when the air inlet
port is released.
(5) While holding the air inlet port closed, apply vacuum
(3.43 kPa, 25.7 mmHg, 1.01 in.Hg) to the EVAP port
and check that air flows into the purge port.
If operation is not as specified, replace the charcoal canister.
