Visual Inspection

Components

INSPECTION

1. VISUALLY INSPECT LINES AND CONNECTORS
Look for loose connections, sharp bends or damage.

2. VISUALLY INSPECT FUEL TANK FILLER PIPE
Look for deformation, cracks or fuel leakage.




3. VISUALLY INSPECT FUEL TANK CAP
Check if the cap and/or gasket are deformed or damaged.
If necessary, repair or replace the cap.




4. 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/sq.cm, 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 tiller pipe.
e. Reconnect the EVAP line hose to the charcoal canister.





5. INSPECT FUEL CUTOFF VALVE AND FILL CHECK VALVE
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/sq.cm, 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.




6. CHECK AIR INLET LINE
a. Disconnect the air inlet line hose from the charcoal canister.
b. Check that there is ventilation in the air inlet line.
c. Reconnect the air inlet line hose to the charcoal canister.




7. REMOVE CHARCOAL CANISTER ASSEMBLY
a. Remove the 2 nuts and tailpipe band.
b. Remove the 4 bolts and suspension member stay.
c. Disconnect the [1][2]VSV connector.
d. Disconnect the vapor pressure sensor connector.
e. Disconnect the purge line hose, EVAP line hose and air inlet line hose from the charcoal canister.
f. Disconnect the vent line hose from the charcoal canister.
1. Push the connector deep inside.
2. Pinch portion A.
3. Pull out the connector.
g. Remove the 2 bolts and the charcoal canister assembly.




8. INSPECT CHARCOAL CANISTER
a. Visually check the charcoal canister for cracks or damage.




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/sq.cm, 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/sq.cm, 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 mm Hg, 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.
6. Remove the cap from the vent port.

9. INSPECT VSV FOR EVAP

10. INSPECT VSV FOR VAPOR PRESSURE SENSOR

11. INSPECT VAPOR PRESSURE SENSOR

12. REINSTALL CHARCOAL CANISTER ASSEMBLY
