INSPECTION
1. VISUALLY INSPECT LINES AND CONNECTORS
Visually check for loose connections, sharp bends or damage.
2. VISUALLY INSPECT FUEL TANK FILLER PIPE
Visually check for deformation, cracks or fuel leakage.
3. INSPECT FUEL TANK CAP
Visually check if the cap and/or gasket are deformed or dam-
aged.
If necessary, repair or replace the cap.
4. INSPECT EVAP SYSTEM LINE
(a) Warm up the engine and stop the engine.
Allow the engine to warm up to normal operating tempera-
ture.
(b) Install a vacuum gauge (EVAP control system test equip-
ment vacuum gauge) to the EVAP service port on the
purge line.
(c) TOYOTA Hand-Held Tester:
Forced driving of the VSV for the EVAP.
(1) Connect  a TOYOTA hand-held tester to the DLC3.
(2) Start the engine.
(3) Push the TOYOTA hand-held tester main switch
ON.
(4) Use the ACTIVE TEST mode on the TOYOTA
hand-held  tester to operate the VSV for the EVAP.
(d) If you have no TOYOTA  Hand-Held  Tester:
Forced driving of the VSV for the EVAP.
(1) Disconnect the VSV connector for the EVAP.
(2) Connect  the positive (+) and negative (-) leads from
the battery to the VSV terminals for the EVAP.
(3) Start the engine.

(3) Check if the pressure decreases when the fuel tank
cap is removed while adding pressure.
HINT:
If the pressure does not decrease when the filler cap is re-
moved, then you can conclude that the hose connecting the
service port to the fuel tank is blocked, etc.
(k) Disconnect  the pressure gauge from the EVAP service
port on the purge line.
5. CHECK AIRTIGHTNESS IN FUEL TANK AND FILLER
PIPE
(a) Disconnect  the EVAP line hose from the charcoal canister
side and then pressurize and make the internal pressure
in the fuel tank 4 kPa (41 gf/cm
2, 0.58 psi).
(b) Check that the internal pressure of the fuel tank can be
hold for 1 minute.
(c) Check the connected portions of each hose and pipe.
(d) Check the installed parts on the fuel tank.
If there is no abnormality, replace the fuel tank and filler pipe.
(e) Reconnect the EVAP line hose to the charcoal canister.
6. INSPECT FUEL CUTOFF VALVE AND FILL CHECK
VA LV E
(a) Disconnect  the purge line hose and EVAP line hose from
the charcoal canister.
(b) Plug the cap to the air drain hose.
(c) Pressurize 4 kPa (41 gf/cm
2, 0.58 psi) to the purge port
and check that there is ventilation through the EVAP line
hose.
HINT:
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 for the pressure switching
valve.
(b) Disconnect  the vapor pressure sensor connector.
(c) Disconnect  the fuel hose from the vapor pressure sensor.
(d) Disconnect  the purge line hose, EVAP line hose and air
inlet line hose from the charcoal canister.
(e) Disconnect  the vent line hose from the charcoal canister.
(1) Push the connector deep inside.
(2) Pinch portion A.
(3) Pull out the connector.
(f) Remove the 2 charcoal canister mounting bolts.
(g) Remove the vapor pressure sensor mounting bolt.
(h) 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 the 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.
