ON−VEHICLE INSPECTION
1. CHECK FUEL PUMP OPERATION
(a) Connect the TOYOTA hand−held tester to the DLC3.
(b) Turn the ignition switch ON and TOYOTA hand−held tes-
ter main switch ON.
NOTICE:
Do not start the engine.
(c) Select the active test mode on the TOYOTA hand−held
tester.
(d) Please refer to the TOYOTA hand−held tester operator’s
manual for further details.
(e) If you have no TOYOTA hand−held tester, connect the
positive (+) and negative (−) leads from the battery to the
fuel pump connector (See page SF−5).
(f) Check that there is pressure in the fuel inlet hose from the
fuel filter.
HINT:
If there is fuel pressure, you will hear the sound of fuel flowing.
If there is no pressure, check the H−fuse, fuses, EFI main relay,
circuit opening relay, fuel pump, ECM and wiring connections.
(g) Turn the ignition switch to LOCK.
(h) Disconnect the TOYOTA 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 air cleaner assembly (See page ST−4).
(d) Remove the 2 bolts, and disconnect the engine comport-
ment R/B No.2 from the bracket on the body.
(e) Remove the union bolt and 2 gaskets, and disconnect the
fuel inlet hose from the fuel filter outlet.
CAUTION:
Put a shop towel under the fuel filter. Slowly loosen the
union bolt.

Torque: 29 N·m (300 kgf·cm, 22 ft·lbf)
(g) Wipe off any splattered gasoline.
(h) Connect the TOYOTA hand−held tester to the DLC3.
(i) Reconnect the negative (−) terminal cable to the battery.
(j) Turn the ignition switch ON.
(k) Measure the fuel pressure.
Fuel pressure:
301 − 347 kPa (3.1 − 3.5 kgf/cm
2, 44 − 50 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check these parts:
Fuel hoses and connections
Fuel pump
Fuel filter
Fuel pressure regulator
(l) Remove the TOYOTA hand−held tester from the DLC3.
(m) Start the engine.
(n) Measure the fuel pressure at idle.
Fuel pressure:
301 − 347 kPa (3.1 − 3.5 kgf/cm
2, 44 − 50 psi)
(o) Stop the engine.
(p) Check that the fuel pressure remains as specified for 5
minutes after the engine has stopped.
Fuel pressure:
147 kPa (1.5 kgf/cm
2, 21 psi) or more
If pressure is not as specified, check the fuel pump, pressure
regulator and/or injectors.
(q) After checking fuel pressure, disconnect the negative (−)
terminal cable from the battery and carefully remove the
SST to prevent gasoline from splashing.
SST 09268−45012
(r) Reconnect the fuel inlet hose with 2 new gaskets and the
union bolt.
Torque: 29 N·m (300 kgf·cm, 21 ft·lbf)
(s) Reconnect the negative (−) terminal cable to the battery.
(t) Check for fuel leakage (See page SF−1).
(u) Reinstall the engine comportment R/B No.2 and air clean-
er assembly.
3. CHECK FUEL PUMP
(a) Remove the LH rear seat assembly.
(b) Remove the floor service hole cover.
