2. CONNECT TOYOTA HAND-HELD TESTER OR OBDII SCAN TOOL (See page EM-9)
3. INSPECT IDLE SPEED
(a) Race the engine speed at 2,500 rpm for approx. 90 seconds.
(b) Check the idle speed.
Idle speed:
750 ± 50 rpm
(w/ Cooling fan OFF and transmission in neutral position)
If the idle speed is not as specified, check the IAC valve and air intake system.

INSPECTION
1. VISUALLY INSPECT LINES AND CONNECTIONS
Look for loosen connections, sharp bends or damage.
2. VISUALLY INSPECT FUEL TANK
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. REMOVE CHARCOAL CANISTER
5. REMOVE CAP FROM CHARCOAL CANISTER
6. VISUALLY INSPECT CHARCOAL CANISTER
Look for cracks or damage.
7. INSPECT FOR CLOGGED FILTER AND STUCK
CHECK VALVE
(a) Using low pressure compressed air4.71 kPa (48 gf/cm
2,
0.68 psi), blow into port A and check that air flows from the
other ports.
If operation is not as specified, replace the charcoal canister.
(b) Blow air 4.71 kPa (48 gf/cm
2, 0.68 psi) into port B and
check that air does not flow from the other ports.

(d) Install the fuel inlet hose and SST (pressure gauge) to the
fuel filter outlet with the 3 gaskets and union bolt.
SST 09268-45012
Torque: 29.0 N´m (290 kgf´cm, 22 ft´lbf)
(e) Wipe off any splattered gasoline.
(f) Reconnect the negative (-) terminal cable to the battery.
(g) Connect the TOYOTA hand-held tester to the DLC3 (See
step 1 check fuel pump operation (a) to (f)).
(h) Turn the ignition switch ON.
(i) Measure the fuel pressure.
Fuel pressure:
281 - 287 kPa
(2.87 - 2.93 kgf/cm
2, 40.8 - 41.7 psi)
If pressure is high, replace the fuel pressure regulator.
(j) If pressure is low, check these parts:
Fuel hoses and connection
Fuel pump
Fuel filter
Fuel pressure regulator
(k) Remove the TOYOTA hand-held tester from the DLC3.
(l) Reinstall the fuse cover on instrument panel.
(m) Start the engine.
(n) Disconnect the vacuum sensing hose from the fuel pres-
sure regulator.
(o) Measure the fuel pressure at idle.
Fuel pressure:
281 - 287 kPa (2.87 - 2.93 kgf/cm
2, 40.8 - 41.7 psi)
(p) Reconnect the vaccum sensing hose to the fuel pressure
regulator plug the hose end.
(q) Measure the fuel pressure at idle.
Fuel pressure:
226 - 265 kPa (2.3 - 2.6 kgf/cm
2, 33 - 37 psi)
If pressure is not as specified, check the vacuum sensing hose
and fuel pressure regulator.
(r) Stop the engine.
(s) 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 injector.
(t) 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
(u) Connect the fuel inlet hose to the fuel filter with 2 new gas-
kets and the union bolt.

INSTALLATION
1. INSTALL FUEL PRESSURE REGULATOR
(a) Apply a light coat of gasoline to a new O-ring, and install
it to the pressure regulator.
(b) Attach the pressure regulator to the delivery pipe.
(c) Check that the pressure regulator rotates smothly.
NOTICE:
If it does not rotate smothly, the O-ring may be pinched, so
remove the pressure regulator and perform again steps (b)
and (c) above.
(d) Install the pressure regulator with the 3 bolts.
