(g) Install SST (pressure gauge) and a fuel tube connector using SST as shown in the illustration.
SST 09268±41047(95336±08070),09268±45014 (09268±41250, 09268±41200, 09268±41220)
(h) Wipe up any gasoline.
(i) Reconnect the negative (±) battery cable.
(j) Connect the hand±hand tester to the DLC3.
(k) Measure the fuel pressure. Fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf/cm
2, 44 to 50 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the fuel hoses connections, the fuel
pump, the fuel filter and the fuel pressure regulator.
(l) Disconnect the hand±held tester from the DLC3.
(m) Start the engine.
(n) Measure the fuel pressure at idle. Fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf/cm
2, 44 to 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, the pres-
sure regulator and/or the injectors.
(q) After checking the fuel pressure, disconnect the negative (±) battery cable and carefully remove SST and the fuel
tube connector to prevent gasoline from splashing.
(r) Reconnect the No. 1 fuel pipe (fuel tube connector).
CAUTION:
After taking the precautions, connect the fuel tube con-
necter (quick type).
2. CHECK FUEL PUMP OPERATION AND FUEL LEAK
(a) When using the hand±held tester (1) Connect the hand±held tester to the DLC3.
(2) Turn the ignition switch ON and the hand±held tes-
ter main switch ON.
NOTICE:

PRECAUTION
1.PRECAUTION
(a)Before working on fuel system, disconnect negative (±) battery cable.
(b)Do not smoke or work near fire when handling the fuel system.
(c)Keep gasoline away from rubber or leather parts.
2.DISCHARGE FUEL SYSTEM PRESSURE
CAUTION:

Do not disconnect any part of the fuel system until
you have discharged the fuel system pressure.

Even after discharging the fuel pressure, place a
shop rag over fittings as you separate them to reduce
risk of fuel spray on yourself or in the engine compart-
ment.
(a)Disconnect the fuel pump connector.
(b)Start the engine. After the engine has stopped, turn the ignition switch OFF.
(c)Disconnect the negative (±) battery cable.
(d)Connect the fuel pump connector.
3.FUEL SYSTEM
(a)When disconnecting the high fuel pressure line, a large amount of gasoline will spill out, so observe these proce-
dures.
(1)Discharge the pressure in the fuel system. (See step 2)
(2) Disconnect the fuel pump tube. (See page 11±93)
(3) Drain the fuel that remained inside the fuel pump tube.
(4) Cover the disconnected fuel pump tubes with a vinyl or a plastic bag to prevent damage and dirt.
(5) Place a tray under the vehicle or point of disconnec-
tion to catch any fuel that may spill.

AVENSIS REPAIR MANUAL (RM1018E)
ON±VEHICLE INSPECTION
1. INSPECT INTAKE AIR SYSTEM
(a) Check for leakage or clogging between the air cleaner
housing and turbocharger inlet and between the turbo-
charger outlet and cylinder head.
(1) Clogged air cleaner...Clean or replace element
(2) Hoses collapsed or deformed...Repair or replace
(3) Leakage from connections...Check each connec-tion and repair
(4) Cracks in components...Check and replace
2. INSPECT EXHAUST SYSTEM
(a) Check for leakage or clogging between the cylinder head
and turbocharger inlet and between the turbocharger out-
let and exhaust pipe.
(1) Deformed components...Repair or replace
(2) Foreign material in passages...Remove
(3) Leakage from components...Repair or replace
(4) Cracks in components...Check and replace
3. CHECK TURBOCHARGING PRESSURE
(a) Warm up the engine.
(b) Using a 3±way connector, connect SST (turbocharger pressure gauge) to the hose leading to the intake air con-
nector.
SST 09992 ± 00242
(c) While depressing the clutch pedal, press the accelerator pedal down to the full. Measure the turbocharging pres-
sure at maximum speed (5,100 to 5,250 rpm).
Standard pressure:
15 to 45 kPa (0.15 to 0.46 kgf/cm
2, 2.2 to 6.5 psi)
If the pressure is less than specification, check both the intake
air and exhaust systems for leakage.
If there is no leakage, check if the actuator hose has discon-
nected. If not, check the turbocharger.
If the pressure is greater than specification, check if the actua-
tor hose has disconnected or cracked. If not, check the turbo-
charger.
4. INSPECT TURBO PRESSURE SENSOR
(a) Inspect power source voltage (1) Disconnect the turbo pressure sensor connector.
(2) Turn the ignition switch ON.
(3) Using a voltmeter, measure the voltage between
connector terminals 3 (VC) and 1 (E2) of the wiring
harness side.
Voltage: 4.5 to 5.5 V
(4) Turn the ignition switch OFF.
(5) Reconnect the turbo pressure sensor connector.

PRECAUTION
1. MAINTENANCE PRECAUTION
(a) Do not stop the engine immediately after pulling a trailer,
or after driving at a high speed, or uphill drive. Let the en-
gine Idle for 20 to 120 seconds before turn the ignition
switch OFF (According as the driving condition, the idling
time varies).
(b) Avoid quick acceleration or quickly accelerating the en- gine RPM immediately after the starting a cold engine.
(c) If the turbocharger is found to be defective, it must be re-
placed. Also, inspect a source of the trouble including
conditions of the turbocharger that having been used. Re-
pair or replace the followings as necessary:
(1) Engine oil (Level and quality)
(2) Oil lines leading to the turbocharger
(d) Pay due attention when removing and reinstalling the turbocharger assembly. Do not drop, or do not give shock,
or do not grasp easily±deformed assembly parts such as
the actuator or push rod in removal and reinstallation.
(e) Before removal, cover both the intake and exhaust ports
and the oil inlet to prevent dirt or foreign objects from be-
ing introduced.
(f) If replacing the turbocharger, check for deposits in the oil pipe. If necessary, replace the oil pipe too.
(g) Thoroughly remove old gasket sticking to the lubrication oil pipe flange and the turbocharger oil flange.
(h) If replacing the bolt(s) or nut(s), must use Toyota genuine parts to prevent breakage or deformation.
(i) If replacing the turbocharger, put 20 cm
3 (1.2 cu in.) of
fresh oil into the turbocharger oil inlet hole and turn the tur-
bine wheel by hand to spread oil to the bearing.
(j) If overhauling or replacing the engine, cut the fuel supply after reassembly and crank the engine for 30 seconds to
feed oil throughout the engine then run the engine at idle
for 60 seconds.
