INSPECTION

1.

DISCONNECT CHARCOAL CANISTER ASSEMBLY
FROM BODY

Remove the 3 nuts, and disconnect the charcoal canister from
the body.
2.

REMOVE VSV

3.

INSPECT VSV

(a)

Inspect the VSV for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the terminals.
Resistance: 33 – 39

Ω

at 20

°

C (68

°

F)

If there is no continuity, replace the VSV.

(b)

Inspect the VSV for ground.
Using an ohmmeter, check that there is no continuity be-
tween each terminal and the body.

If there is continuity, replace the VSV.

(c)

Inspect the VSV operation.
(1)

Check that air flows from ports E to G.

(2)

Apply battery positive voltage across the terminals.

(3)

Check that air flows from ports E to F.

If operation is not as specified, replace the VSV.

INSPECT ECT SENSOR

Using an ohmmeter, measure the resistance between the ter-
minals.

Resistance: Refer to the graph

If the resistance is not as specified, replace the ECT sensor.
4.

REINSTALL ECT SENSOR

(a)

Install a new gasket to the ECT sensor.

(b)

Using SST, install the ECT sensor.

FUEL PUMP

ON–VEHICLE INSPECTION

1.

CHECK FUEL PUMP OPERATION

(a)

Connect a LEXUS hand–held tester to the DLC3.

(b)

Turn the ignition switch ON and LEXUS hand–held tester
main switch ON.

NOTICE:
Do not start the engine.
(c)

Select the ACTIVE TEST mode on the LEXUS hand–held
tester.

(d)

Please refer to the LEXUS hand–held tester operator’s
manual for further details.

(e)

If you have no LEXUS hand–held tester, connect the pos-
itive (+) and negative (–) leads from the battery to the fuel
pump connector. (See step 3)

(f)

Check that the pulsation damper screw rises up when the
fuel pump operates.

If there is no pressure, check the fusible link, fuses, EFI main
relay, fuel pump ECU, fuel pump, ECM and wiring connections.
(g)

Turn the ignition switch OFF.

(h)

Disconnect the LEXUS hand–held tester from the DLC3.

2.

CHECK FUEL PRESSURE

(a)

Check the battery positive voltage is above 12 V.

(b)

Disconnect the negative (–) terminal cable from the bat-
tery.

(c)

Remove the union bolt and 2 gaskets, and disconnect the
fuel inlet hose from the fuel pipe support.

NOTICE:

Put a shop towel under the fuel pipe support.

Slowly loosen the union bolt.

(d)

Install the fuel inlet hose and SST (pressure gauge) to the
fuel pipe support with the 3 gaskets and SST (union and
adapter).
