Inspection

1. REMOVE EXHAUST TAIL PIPE AND HEATED INSULATOR (See page EM-115)

2. INSPECT LINES AND CONNECTORS

Visualiy check for loose connections, sharp bends or damage.

3. INSPECT FUEL TANK FILLER PIPE

Visually check for deformation, cracks or fuel leakage.

4, INSPECT FUEL TANK CAP

Visually check if the cap and/or gasket are deformed or damaged.

If necessary, repair or replace the cap.

5. INSPECT EVAP SYSTEM LINE

(a) Warm up the engine and stop the engine.

Allow the engine to warm up to normaf operating temperature.

(b) Instafi a vacuum gauge (EVAP control system test equipment 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.

(e) Check the vacuum at idle. Vacuum:

Maintain at 0.368 -19.713 in.Hg (5 - 268 in.Aq) for over 5 seconds

HINT:

If the vacuum does not change, you can conclude that the hose connecting the VSV to the sen/ice port has come loose or is blocked, or the VSV is malfunctioning.

(f) If you have TOYOTA hand-held tester: Conclude forced driving of the VSV for the EVAP.

(1) Stop the engine.

(2) Disconnect the TOYOTA hand-held tester from the DLC3.

(g) if you have no TOYOTA hand-held tester: Conclude forced driving ol the VSV for the EVAP.

(1) Stop the engine.

(2) Disconnect the positive (+) and negative (-) leads from the battery, and from the VSV terminals for the EVAP,

(3) Connect the VSV connector for the EVAP.

(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.

Pressure Gauge A

(j) Check the pressure.

(1) Close off the air drain hose at the marked position of the canister with a hose clipper or similar instrument.

Pressure Gauge A

IS h

(2) Add the pressure (13.5 -15.5 in.Aq) from the EVAP

service port. Pressure:

2 minutes after the pressure is added, the gauge should be over 7.7 - 8.8 in.Aq.

HINT

If you can't add pressure, you can conclude that the hose connecting the VSV-canister-fuel tank has slipped off or the VSV is open.

(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 fiiler cap is removed, 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.

6. CHECK AIRTIGHTNESS IN FUEL TANK AND FILLER PIPE

(a) Disconnect the EVAP line hose from the charcoal canister.

(1) Pinch portion A.

(2) Pull out the connector.

(b) Pressurize and make the internaf pressure in the fuel tank 4 kPa (41 gf/cm2, 0.58 psi).

(c) Check that the internal pressure of the fuel tank can be held for 1 minute.

(d) Check the connected portions of each hose and pipe.

(e) Check the installed parts on the fuei tank.

If there is no abnormality, replace the fuel tank and filler pipe. (0 Reconnect the EVAP line hose to the charcoal canister.

INSPECT FUEL CUTOFF VALVE AND FILL CHECK VALVE

Disconnect the purge line hose and EVAP line hose from the charcoal canister. Plug the cap to the air drain hose. Pressurize 4 kPa (41 gf/cm2, 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 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 anything stuck in the vent line hose and EVAP line hose.

If there is nothing stuck in them, replace the fuel cut off valve and fill check valve.

(e) Reconnect the purge line hose and EVAP line hose to the charcoal canister.

8. 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.

9. REMOVE CHARCOAL CANISTER ASSEMBLY

(a) Disconnect the VSV connector.

(b) Disconnect the purge line hose, EVAP line hose and air inlet line hose from the charcoal canister.

(c) Disconnect the vent line hose from charcoal canister.

(1) Push the connector deep inside. |

(2) Pinch portion A.

(3) Pull out the connector.

(d) Remove the 3 nuts and charcoal canister assembly.

(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/cm2, 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/cm2, 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.

li a problem is iound, replace the charcoal canister.

(6) Remove the cap from the vent port.
